What is Bottom Paint?

Why bottom paint a boat, primer/barrier coat, estimated cost, cost for labor, hauling and storage fees, cost per square foot, materials needed, time needed, when is it unnecessary to bottom paint a boat.

Bottom paint is also often called antifouling marine paint. It is a specially formulated paint or paints that coat the bottom of a boat. This multi-layer coating helps discourage the growth of aquatic organisms on the boat.

Bottom paint coats the bottom of the boat in order to discourage the growth of fouling aquatic organisms. These organisms, such as barnacles and algae, adhere to solid surfaces in the water, such as the bottom of your boat.

These aquatic organisms grow fast. You may try to keep up with scraping down the bottom of the boat, but it will be difficult to keep up with the growth on the underside.

All those barnacles and algae will slow down your boat, as well. The increased water resistance may cause as much as a 50% loss in hull through water efficiency. Not only will that cost you time, but you’ll spend more on diesel to get you to your destination. If your prop has aquatic organisms, your engine will suffer , as well.

What Paint is Needed for Bottom Painting a Boat?

Bottom painting a boat usually involves three layers of paint applied to the bottom of the boat. Typically, you will need two coats of each kind of paint.

The first coat of paint will be either an epoxy primer or a barrier coat . The two-part epoxy primer is perfect for repairs to the bottom of the boat. It will dry rock hard for a durable base coat.

A barrier coat is a similar, hard paint that will adhere to fiberglass, repair damage, and dry hard. Barrier coats are typically only used on fiberglass boats. Based on the condition of your boat, you would choose either a primer or a barrier coat.

The base coat of paint will be an antifouling paint or an ablative paint . This softer layer of paint will provide a layer to repel the build-up of marine growth.

Antifouling paint is quick-drying. It will slowly self-polish or wear down over time. This helps reduce the build-up of paint.

Ablative paint is very similar to antifouling paint. Often, the two terms are used interchangeably. Ablative paint is self-polishing as well. As the boat is in use, the paint will wear away gradually. It also repels aquatic organisms.

If you have an aluminum boat, avoid antifouling paint that includes copper. Copper may cause corrosion on the aluminum unless you have a protective primer in place between the boat and the antifouling paint.

The top coat is a gel coat that gives the boat a glossy, protective finish. This step may be skipped, depending on the antifouling paint, and your desired finish on the boat.

How Much Does It Cost to Hire Someone to Bottom Paint a Boat?

Most boat painters charge by the foot. For a 17-18 foot boat, expect to pay a total of between $1,200 to $3,000 or more to bottom paint a boat. As with any important job, it may be best to drop the lowest estimate and go with a reputable business that will treat you and your boat well.

Your dollars pay for materials, labor, and hauling, and storage fees.

Depending on the size of the boat, and the amount of work involved, a professional will probably spend between 10-20 hours painting the bottom of your boat. Most painters will charge $50-$100 per hour for labor. As you can see, labor makes up a good portion of your bill!

Often, your boat will need to be hauled to a painter, and stored during the painting process. Of course, there is a fee for this, as well. Most boat yards will charge by the linear foot to haul, wash, and block the boat. This fee is typically between $6-$10 per foot.

Yard storage fees are typically by the month. Often, boat owners will have their boat bottom painted during the off-season and will pay for several months of storage. Depending on the location, and the boat, be prepared to spend $100-$300 per month for storage fees.

In addition to paint, you are paying for the use of the painter’s brushes, tools, and equipment. The cost for paint for a 17-18 foot boat depends on the variety of paint used. Antifouling paint is fairly expensive. The cost for materials will be around $400-$700.

If you have about 200 square feet of paintable area on the bottom of your boat, your cost per square foot to bottom paint a boat will be $6-$15 or more.

How Much Does it Cost to DIY Bottom Paint a Boat?

If you are painting your boat yourself, your only costs are materials. For a 17-18 foot boat, the cost for materials will be $500-$800. This depends on the condition of your boat, as well.

Boat Primer is the first step. This primer covers 200 square feet at under hundred bucks. Next, this antifouling paint costs slightly more. One gallon covers 500 square feet, so that will be enough for two coats.

The final layer of paint is a gel coat . If you want to build up several layers of gel coat, you will need 3-8 gallons of gel coat at around $35 per gallon. For 5 gallons, that would be $175.

You will also need brushes, paint suits, rollers, and other painting supplies. Plan to spend $30-$50 on these supplies.  The fees to haul, block, and launch will be around $300.

The total amount for materials will be about $750.

If you have never bottom painted a boat or have extensive scraping and cleaning, be prepared to spend a little extra time. Otherwise, to bottom paint around 200 square feet of the boat, it will probably take 15-25 hours.

For 200 square feet of paintable space, the cost per square foot to bottom paint your boat yourself will be around $3.75.

If your boat is not stored in the water, it may not be necessary to use bottom paint. If you typically have your boat in a trailer or dry storage when it is not in use, it will be easy to perform regular maintenance. You should be able to remove all aquatic growth in between uses.

Final Thoughts

Bottom painting is a good investment for boats that spend a lot of time in the water! Evaluate your priorities. If you have the time, you can save a lot of money by bottom painting your boat yourself.

Large motor yacht (40 feet or more)

Large motor yachts can be quite the investment, and bottom painting one can cost anywhere from $5,000 to $10,000, depending on the same factors. These boats are large and complex, and the paint job requires significant skill and experience.

It’s worth noting that these estimates are just that – estimates. The cost of bottom painting your boat will depend on the specific factors that apply to your situation.

Factors that Affect the Cost of Bottom Painting a Boat

Regarding bottom painting a boat, several factors can affect the cost. Understanding these culprits can help you better estimate the cost of bottom painting for your boat. Here are them: 

Size Of The Boat

The size of the boat is one of the most significant factors determining the cost of bottom painting. Larger boats require more paint and labor to paint, increasing the cost. For example, the cost of bottom painting a 20-foot sailboat would be significantly less than that of a 40-foot motor yacht.

Type Of Paint And Primer Used

The type of paint and primer used can also affect the cost of bottom painting. Certain types of paint and primer are more expensive than others, which can increase the cost. For example, using a high-quality, multi-seasonal paint or a built-in anti-fouling agent will likely be more expensive than a basic bottom paint.

Condition Of The Boat’s Hull

The condition of the boat’s hull also plays a role in determining the cost of bottom painting. If the boat’s hull is in poor condition, it may require additional work, such as sandblasting or hull repair, before the bottom paint can be applied. These additional services increase the cost of bottom painting.

The location also affects the cost of bottom painting, as the cost of labor can vary significantly from one area to another. Bottom painting a boat will cost more in areas with a higher cost of living.

For example, bottom painting a boat in a central metropolitan area will likely be more expensive than painting the same boat in a rural area.

Additional Services

Any additional services required, such as sandblasting or hull repair, will also increase the cost of bottom painting. For example, if the bottom of the boat needs to be sandblasted before the paint is applied, the price will be higher than if the boat’s hull was in good condition and did not require sandblasting.

Does the Drying Time of Chalk Paint Affect the Cost of Bottom Painting a Boat?

The drying time of chalk paint can impact the cost of bottom painting a boat. Faster drying time means fewer labor hours and potentially lower costs. However, slower drying time may require additional time and effort, leading to higher expenses for the boat owner. Consider the chalk paint drying time when budgeting for bottom painting.

What are the Cost Estimates for Bottom Painting a Boat vs Using Rhino Shield for Protection?

When considering the cost estimates for bottom painting a boat versus using Rhino Shield for protection, it’s important to weigh the rhino shield pros and cons . While bottom painting may be a more affordable upfront option, Rhino Shield offers longer-lasting protection and potential cost savings in the long run.

How to Save Money on Bottom Painting?

While bottom painting is important to protect a boat’s hull, the cost can be significant. Here are some ways to save money on the cost of bottom painting your boat:

Do It Yourself

Painting your boat by yourself can save you a significant amount of money. You’ll need to buy the paint, supplies, and tools to do it yourself, but the cost will be significantly less than hiring a professional. Ensure you thoroughly research the process, as proper preparation and paint application are essential for a successful job.

Shop Around

Before you commit to a paint job, shop around to compare prices. Don’t be afraid to negotiate; some yards may be willing to lower their rates if you’re eager to do some prep work, such as sanding and cleaning the hull.

Use A Less Expensive Paint

Budget paints can be an effective way to save money, but do your research. Many budget paints don’t last as long as more expensive paints, so you may have to repaint them more often, which can cost you more in the long run.

Preparing the Bottom of Your Boat for Painting?

Bottom painting is essential to maintaining a boat’s hull and protecting it from the harsh marine environment. The cost of bottom painting can vary widely depending on several factors, such as the size of the boat, the type of paint and primer used, the condition of the boat’s hull, location, and additional services.

By understanding these factors and taking steps to prepare the boat for painting, doing it yourself, and using less expensive paint or primer, you may be able to save money on the cost of bottom painting without compromising on the quality of the work.

It is essential to remember that bottom painting is an investment in the longevity and performance of your boat, and it is crucial to budget accordingly.

How Much Does it Cost to Antifoul a Boat? (Bottom Paint)

Bottom painting is one of the many ongoing expenses you can plan for when you buy a boat. You don't have to do it every year, but unless you dry sail the boat or keep it in pristine fresh water, you will have to do it. It's not hard to figure out once you take all the factors in.

Painting the bottom of a moderate-sized boat in a yard will cost between $20 and $45 per foot. A 25-foot yacht will cost you around $800. A 40-foot yacht will cost you around $1,300. This cost ranges quite a lot because of many variables, but you can control some of those to rein in the costs.

Below, I'll go over the different variables that will affect the cost. Read on to learn how to save money.

On this page:

The average cost for antifouling, what is included in the cost, what drives the cost up, how to save some money, planning your project.

To make things easier, I've created a table with the cost range for different boat lengths:

Typically, the following is included:

Consumables, environmental, insurance, and disposal charges.

The specifics of any bid you receive to paint your bottom will vary from yard to yard. You need to be careful to read each quote carefully, as there are many small items you may find that add up. To antifoul a boat properly, there are several specific items that should be quoted in detail.

The yard may give you a quote stated on a per foot basis for your boat, or they may give you an estimate based on your boat specifics. I've had yards quote me per foot as an off-the-cuff estimate, then hand me a detailed bill at the end that doesn't really match the per foot estimate. I'd rather see an estimate for hours of labor and lists of materials.

Discuss what it includes before you accept the bid and start work so you understand the final bill.

The specific paint you choose will affect the end price, as paint quality and prices ranges from around $100 a gallon to close to $300. Most yards will estimate how many gallons you need, but you may find the final bill used more (or maybe less!) paint than the estimate included.

The yard should also help you choose a paint, but take care to research your needs yourself so you can make an informed decision and not put on a more expensive paint than you need.

The hourly rate for yard labor may shock you if this is your first boat. But even a task like bottom painting will cost a significant amount per hour. Most quotes for painting will be based on estimated hours, rather than exact hours.

If a marina quotes you "$35/foot" on a painting job, there should not be extra or excessive charges for labor on top of this. The exception is if there are problems found which require extra preparation or work. Most responsible yards will contact you if this happens.

Rubber gloves, sandpaper, masking tape, protective masks, paint stirrers, and Tyvek suits are among the consumable items they may bill you for as part of a bottom job. It surprised me the first time I had a yard paint my boat to see a two page bill for just rolling on the paint. Don't assume the quote is for anything but paint and labor; make sure it includes consumables as these may add hundreds of dollars to the final bill.

Also, don't assume you'll be charged anything less than full retail price from the ship's store for these items, or that you will only pay for what they use. For example, if masking tape is used, you may see a charge for an entire roll. It is best to discuss these things in advance with the yard to avoid surprises.

Many states and countries now leverage various environmental charges and fees associated with marina work. Bottom painting runs afoul of these because of the inherent toxicity of the paint. Yards usually pass these on to the boat owner. They may be a flat fee or a percentage of the total bill. Ask upfront what they will be and if they are mandatory.

What makes this job so expensive? Why is one boat so much more to antifoul than another? Bigger boats cost more to protect, this is unavoidable. But what else makes this

Size of the boat

A longer boat does not have a simple linear relationship between its length and the amount of paint it needs. My son's Capri 22 needed less than a gallon of paint for a thorough paint job; our fifty-three footer takes eight to ten gallons of the same paint for a proper application. We're two-and-a-half times the length, but twenty-five times the displacement.

So many yards have sliding scales on a per foot basis, with bigger boats costing more. The more the displacement of the boat, the more labor and materials it takes to paint it.

Prep Work and the Old Paint

Ideally, your last bottom job would need only a light cleaning and sanding before they apply new paint. Even this is a fair amount of labor. But conditions are rarely ideal.

Paint which is flaking or chipping may require additional preparation. This may mean sanding or filling to smooth flaked areas, and extra preparation where paint may have completely flaked off.

Bottoms with growth or encrustations may take considerably more time to make ready. The yard will pressure wash the bottom when the boat is hauled, but this will not take care of excessive growth. This is a strong argument for regular painting and occasional bottom scrubbing - it can save you a lot of money the next time you paint.

If you change the type or manufacturer of paint, the old paint may have to be completely removed. There may be compatibility issues between types and brands of paint - ignoring them can be an expensive mistake. Sometimes staying with the old brand even if it's not what you want may be a more affordable option if it is still available and legal to use.

Prep work also includes masking off the waterline and underwater gear. If spraying, this will include skirting the boat and protecting it from over-spray.

You should be given an estimate for the prep work needed. Once they start, if the labor will vary more than about 10% of this the yard should contact you to discuss it before proceeding.

Type of Paint

A full study on the types, brands and varieties of paint on the market is beyond this post, but you should be aware there is a considerable range of costs based on the bottom paint you choose. The least expensive bottoms paints are still expensive.

The cheapest paint may not be the best paint for your area or your usage plans. Some paints are more effective in certain regions of the world and this may justify the extra cost. The yard should have familiarity with which types of paints are most effective for local boats.

The absolute cheapest way to antifoul your boat is to do it yourself. It costs you your weekends, not your dollars, and you only buy the supplies you need. If your boat isn't too large and the project manageable, this is a real alternative that a lot of boat owners use. The pros are the lower costs. The cons are that you are dealing with a lot of work with toxic substances and you need to be careful, for your health and for the environment.

If a yard will do the work for you, there are still some steps you can take to make it less expensive. Ways to do this include:

• Supply your own paint. Many yards will let you supply your own even if they are doing the work, and you can often get it for a better price if you buy it yourself. Note: not all yards sell all brands, so choosing a brand the yard does not supply usually requires this.
• Pick the cheaper paint. It may not last as long or be the best choice, but it will provide protection if you're pressed for cash.
• Do some prep work yourself. Sanding bottom paint is a nasty business, but you can do that. It requires elbow grease and protective equipment, but your own labor is cheap. Scrubbing the bottom before it comes out of the water is another way to shortcut preparation.
• Keep your bottom clean. Don't let hard or heavy growth accumulate, this gets very expensive to clean up.
• Paint on a schedule. This goes back to keeping your bottom clean, but if you don't let your paint completely wear out, then you will not have as much growth at the end of the season. If the paint says it's good for two seasons, repaint when you are supposed to.
• Spray vs. Roll. This is a question for your yard, but most yards have different prices for spraying paint versus rolling it as the labor and paint coverage rate is different.

The key to managing your costs is to understand the quotes you get from marinas. Check the following items off to make sure you have estimates so there are no surprises.

• Paint choice and quantity
• Labor hours - rates and estimated time
• Consumables - quantities and costs
• Environmental charges and fees.

How much is bottom paint for a boat per foot? The cost of bottom paint per foot can vary widely depending on the type and brand of paint used. It can range from $10 to $30 or more per linear foot.

How much weight does bottom paint add to a boat? The weight added by bottom paint is relatively minimal and is unlikely to significantly impact a boat’s overall weight or performance.

Do you have to sand a boat before painting? Surface preparation, including sanding, is often necessary before painting a boat to ensure proper adhesion and a smooth finish.

Do you need bottom paint in salt water? Bottom paint is more critical in saltwater environments due to the higher likelihood of marine growth and fouling.

Should I repaint the bottom of my boat each year or just touch it up? You don’t need to repaint the bottom of your boat every year. Touching up areas that need attention between full repaints is often sufficient.

How often should you replace bottom paint? The frequency of replacing bottom paint can vary based on the type of paint and water conditions but is typically done every 1 to 3 years.

What happens if you don’t bottom paint your boat? Without bottom paint, your boat’s hull may be susceptible to marine growth, which can increase drag, reduce fuel efficiency, and potentially cause damage over time.

Can you remove bottom paint from a boat? Yes, it is possible to remove bottom paint from a boat, but it can be a labor-intensive process that often involves scraping, sanding, or using chemical strippers.

What temperature can you bottom paint a boat? The ideal temperature for bottom painting is usually around 50°F (10°C) or higher. Follow the manufacturer’s recommendations for the specific paint you are using.

How many coats of paint on a boat hull? The number of coats of paint on a boat hull can vary, but typically, two coats of hull paint are recommended for proper coverage and protection.

How Much Does It Cost to Paint a Boat? (Price Chart)

One of the most vital questions boat owners have is how much does it cost to paint a boat. It depends on numerous factors and can be $2 to even $400 per linear foot. So, painting may cost you a couple of hundred dollars to at least $5,000.

As you can see, the gap between those two values is vast, so you should check all relevant factors before starting with work. The first thing to decide is hiring a professional or organizing a DIY project. Then, overall costs will vary depending on the paint type and boat size. Let’s take a look.

Table of Contents

Why Should You Paint Your Boat?

Boat painting costs by types, what does affect the boat painting cost.

Whether you have a boat made of fiberglass , wood, or aluminum, its painting is highly beneficial and can prolong its life. It will also increase the vessel value, which is crucial if you plan to sell it in the future.

Plus, specialized paint will protect it from water damage and prevent water plants from sticking. Be prepared that this action is not easy and requires excellent preparation and a lot of hard work. It is estimated that about 75% of the process is preparation work if you want to get the desired boat look.

Before starting, you should determine if you need to paint the whole boat or only its parts. That will directly affect the amount of work and price.

Bottom (antifouling) painting

This painting type includes painting the vessel part below the water level. Most owners who use their boat regularly consider it unnecessary, but it is beneficial for vessels kept mainly on the dock.

Its primary purpose is to protect the hull from damage caused by barnacles and weeds. Remember that it is often unnecessary, but once you paint the boat bottom, it is necessary to regularly clean and re-paint it.

The first thing to do is to pick out the appropriate paint:

Ablative bottom paint – This self-polishing paint is an excellent option for slow-moving boats. It gradually wears away and releases biocides while sailing, making future re-painting effortless.

Hard bottom paint – This durable hard coating is an option for powerboats and other fast boats. The downside is that you need to remove it before re-painting your vessel.

Hybrid (semi-hard ablative) paint – This paint type is suitable for most boats and provides a smooth and hard surface resistant to buildup.

Besides the paint type, overall costs for professional bottom painting will depend on:

• Boat condition
• Way of keeping (in the water, a yard, or on a trailer )

If you decide on a DYI project, you will spend approximately $100 to $500 to complete painting your boat bottom.

Professional service implies the price of $15 to $100 per linear foot, but the average cost is about $20 to $45 per linear foot. That means you should set aside $300 to $800 for an average boat of 20 feet (6 m).

However, that number can reach $2,000, sometimes even $5,000, depending on the boat size, the company you choose, paint quality, and possible bottom damage.

Topside painting

Topside painting has an aesthetic purpose and will protect the boat from water and sunlight exposure. The process includes boat body re-pairs, surface preparation, and primer application.

Before starting, you should determine if you need to paint the whole boat or only its parts, including:

• The interior

That will directly affect the amount of work and price . Remember that painting the boat topside requires a different procedure and paint type than bottom painting.

Overall topside boat painting costs can significantly vary, depending on:

You can choose among three topside paint types:

Alkyd enamel – This oil-based, low gloss paint is easy-to-apply and cheap but has poor color retention and low gloss.

One-part polyurethane – This popular, cheap, and easy-to-apply option is perfect for DIY topside painting.

Two-part polyurethane – This hard, durable, and expensive high-gloss topside paint type is tricky to apply, so it is better to hire a professional to work with it.

Additionally, you should pay more for a sizable boat and plan more money if your vessel is damaged.

The average DIY topside painting price is approximately $350. In this case, you should calculate paint price and add costs for prep materials, like:

• Paintbrush and paint trays
• Masking tape and sandpaper

The professional topside painting will cost you $100 to $400 per linear foot. However, the average price is often $200 to $250 per linear foot for an undamaged boat, particularly when choosing low-quality paint.

For instance, you need to set aside $4,000 to $5,000 for an average 20 feet (6 m) long vessel on average. However, the price range is from $2,000 to $8,000.

Bids you get for painting your boat can significantly vary, but you always need to pay for the same things:

Since different boat parts require specific paints , their price will vary from $100 to $300 per 1 gallon (3.8 l). So, you will get an approximate price after estimating your boat length and how much paint you need per 1 foot (0.3 m).

Remember that most modified epoxy hull paints quire only one coat, but you should calculate two coats when using ablative hull paints. Most hull paints will cost you $20 to $200 per gallon, but the final price will depend on the paint brand and painting style you choose.

Professional hull painting price primarily depends on your boat size and is typical $25 to $125 per linear foot. Remember that this price can be higher when your vessel requires additional re-pairing and more work, while a first painting of the new boat will be charged lower.

As you can expect, boat size will directly affect overall costs. However, professionals sometimes charge a higher rate per linear foot for small boats over bigger ones. The price will also depend on the place where you plan a painting. It is always more pricey when transportation is necessary.

Remember that marina quotes typically include all charges, except when later found problems require extra work. Plus, most professionals will quote for painting based on estimated rather than exact hours necessary to finish the job. They will let you know if some unexpected costs appear.

Consumables

You should also pay for some tools and supplies, such as:

• Rubber gloves, goggles, and protective masks
• Tyvek suits
• Paint stirrers

Always check whether the bill includes those things to prevent unpleasant surprises that count hundreds of dollars. Also, you will pay for everything bought, not only for what they have used.

For instance, you need to pay for an entire masking tape roll, although only a small piece has been used.

Extra costs

Paint stripping – As I have already mentioned, some paints will require stripping before applying a new paint layer, so you need to pay for this work. However, it will make it easier to notice any existing damage and allow better prime.

Customization – Simply said, you need to pay extra if you prefer to give your boat a unique and distinctive look. It is possible to add an application, your initials, or the company logo on the hull.

Professionals typically calculate this service cost by linear feet, so you should count on $100 and $400 for the customizing topside painting and approximately $15 to $100 for the bottom painting.

Insurance and disposal and environmental charges

Professionals will invariably include insurance costs in the final bill. Plus, many states charge environmental charges and marina fees because of paint’s inherent toxicity. So, you should also pay for that, regardless of whether it is a flat fee or a bill percentage. Finally, you need to add disposal charges to overall costs.

Sailing exposes your boat to numerous outdoor elements , making protective painting crucial for prolonging its life. Plus, a freshly coated boat will look more representative, and its price will be higher once you decide to sell it.

The planned budget will depend on the boat size, paint type, and the way of finishing that task. The DIY project will be more affordable, but hiring professionals often means a more appealing boat look.

Boats & Bottom Paint: 15 Quick Answers (For Beginners)

Often when boaters gather for cocktails, the conversation drifts to bottom paint.

This is one of the more costly and frustrating items of boat maintenance, but with proper knowledge, the right bottom paint can be found for your boat.

Table of Contents

1. What is the Purpose of Bottom Paint?

Bottom paint, often called antifouling paint, is formulated to keep marine growth from forming on the bottom of your hull.

This growth can be stringy or slimy green algae or even hard barnacles attached for the free ride.

All growth causes loss of performance and excess fuel costs, and it looks disgusting!

2. How Does Bottom Paint Work?

Bottom paint contains Copper or Tin compounds that are actually poisonous to marine organisms.

Due to the potential to contaminate waterways, there are now bottom paints without heavy metals that use other chemicals to inhibit marine growth. Tin has now been outlawed in the US and other countries.

That leaves Copper and Copper-free formulas.

3. What Are the Different Types of Bottom Paint?

The two basic categories are ablative and hard bottom paints.

Ablative bottom paints slowly wash away as the boat moves or sits in the water. They act like a slowly melting bar of soap. By ablating, they shed some paint along with marine growth.

These paints also have Copper and other chemicals that inhibit growth. By ablating away, they expose fresh layers of paint with fresh chemical compounds.

Do some research among paint manufacturers; there are hard and soft ablative paints.

The soft is more effective in inhibiting growth but doesn’t last as long as harder compounds.

Ablative Paints Are:

• Easy to apply by roller, even over older ablative bottom paint that has been thoroughly cleaned.
• Cost is slightly lower than hard paints.
• The hull bottom stays clean without scrubbing, as long as the paint is not used up.
• It can wash away too quickly, requiring more paint to remain effective.
• They are usually thick and do not provide a slick, smooth hull finish.

Hard bottom paints contain Copper compounds like ablative paints but are thinner, longer-lasting paints. They are designed to be effective for several years and not wear away as quickly.

Hard Paints Are:

• More demanding of surface preparation. All old paint, especially ablative paint, must be removed.
• Require scrubbing, about once/month, to remove marine growth and expose more chemical compounds.
• More costly to buy and apply than ablative paints.
• Provide a smoother, slicker bottom finish for higher performance.

4. What’s the Best Bottom Paint?

That’s a favorite topic in sailor’s bars.

There is no simple answer but let’s look at some guidelines:

Most Important: What’s Under your Bottom Paint?

Fiberglass boats have an outer surface of tough gelcoat.

This is sprayed in the mold before laying up the fiberglass. Gelcoat does absorb a small amount of water.

Therefore, multiple coats are necessary for a water barrier between you and the gelcoat. A good practice is to alternate the coats with gray and white 2000e so you can see in the future how far you have sanded through your barrier coat.

The barrier coat must be sanded before applying bottom paint to have proper adhesion. A sanded barrier coat is the perfect primer for any bottom paint.

Watch Out for Blistering:

Older boats and some newer ones suffer from osmotic blistering of the gelcoat.

This occurs when water absorbs through the gelcoat into the first layers of fiberglass. The water can actually build up pressure that pops the gelcoat up like a blister.

Any boat that has osmotic blistering requires serious, remedial work.

The blisters must be removed by grinding or sandblasting. After the hull is completely dry, the blisters are filled with an epoxy filler and sanded smooth.

To prevent future blistering, layers of epoxy barrier coat must be applied. Interlux 2000e works well.

Fresh Water Boats Have Limited Choices for Bottom Paint:

One choice instead of using bottom paint is to use a boat lift or dry storage.

If not, Interlux VC17 and Petit SR21 work fairly well and are easy to apply.

• They are skinny, so they tend to give a smooth finish.
• They require scrubbing every month, more frequently for racing boats.

Ablative bottom paints work fairly well, too. If they don’t effectively inhibit growth, they will ablate off to remove the growth along with a fraction of the paint.

Salt Water Presents More Challenges:

There is a greater variety of organisms in saltwater that like to hitchhike on your hull.

Warmer water temperatures also accelerate growth.

• Talk with other boaters in your area. Find out what works best.
• Consider how often you will pull your boat out of the water for cleaning or repainting.
• Consider the added expense of hard paint if you can easily snorkel or dive to clean your boat bottom.

5. Can I Apply my Own Bottom Paint?

Most paints have explicit instructions for the DIY boater.

As always, follow the manufacturer’s instructions, but here are valuable tips on a successful bottom job:

• All bottom paints require a sound base to adhere to.
• You don’t want delays in your project.
• There are a lot of solids that need to be dispersed in the paint.
• Temperature and humidity must be within the manufacturer’s specifications. Of course, rain can make a mess of a bottom job.
• Applying thick coats in succession can entrap solvents and cause the paint to remain soft.
• There is nothing worse than a perfect bottom finish marred by lift slings or trailer pads.
• Plan on a week to clean, sand, and apply bottom paint.

6. What Colors are Available in Bottom Paint?

In years past, bottom paint was dull, red copper color.

Now the manufacturers add a variety of tints. Some are quite vivid (Micron Vivid), but most turn a dull color when exposed to water.

All look bad when covered with marine growth, but black seems to hide the appearance of marine growth the best.

7. How About Bottom Paint Safety?

Bottom paints contain chemicals poisonous to marine growth.

They are also toxic to humans and animals.

Sanding old bottom paint is especially dangerous. Wear protective clothing and breathing devices!

There are often environmental regulations regarding sanding, washing, and applying bottom paint. Ask at your boatyard to be sure you comply.

We do not want to pollute the beautiful waters we enjoy on our boats .

8. How Much Bottom Paint will I Need?

Manufacturer’s websites help estimate how much you should buy.

Be aware that some paints have a shelf life. Don’t buy extra that might expire before you re-paint.

We used four quarts of VC17 or SR21 on our 28-foot sailboat in Lake Michigan. We now live aboard a 42-foot sailboat and use four gallons to re-paint.

9. How Long will the Bottom Paint Last?

The goal for most boats that stay in the water year-round is two years.

Our experience is that performance is poor during the second year; we have to do a lot of scrubbing. Boats that are used during only a summer season can often go two years on a bottom job. Some routinely put on a fresh coat every year.

Some hard bottom paints like Coppercoat can last 10 years. This is a highly specialized, epoxy/copper paint that must be applied with care. I saw a boat out of the water that sailed with Coppercoat for two years, and the bottom looked like new.

The owner said they do have to clean the bottom every month, though.

Petit Trinidad SR can last several years but, again, needs monthly scrubbing.

10. What’s New in Bottom Paint?

Copper-free bottom paints have emerged on the market to be more friendly to the environment.

Some contain non-metallic biocides. One unique paint is Epaint, EP 2000. This water-based paint forms a layer of Ozone when in the water. This Ozone is toxic to all marine growth but has no lasting pollutants.

We used it on the keel and rudder of a racing boat, and it stayed immaculate all summer.

It just rolled on like house paint. However, it wasn’t easy to sand to a smooth, racing finish.

11. What’s the Best Bottom Paint for Speed?

The simple answer is “none” because your boat’s factory gelcoat finish is probably smoother than any bottom paint.

If racing performance is the goal, wet sand the gelcoat and keeps cleaning the bottom or hauling between races. We did this for years with our 28-foot race boat, Veloce. We would haul the boat on the yacht club crane and scrub before every race.

It took only ½ hour, and we always had the confidence of a perfect bottom.

For boats that must have an antifouling paint, hard paints are the fastest.

They can be wet sanded to be almost as smooth as gelcoat. Ablative paints, sloppily applied, look like roofing tar. But if applied with care, it can provide a smooth finish.

Remember, any marine growth will be slow, regardless of the type of paint. Antifouling paint will help with boat speed and fuel savings.

12. How Much Does it Cost to Have the Boat Professionally Painted?

There are a lot of factors involved in the cost.

Bottom cleaning and sanding, type of paint, cost to haul and launch the boat, and boat size contribute to cost.

As a rough average, bottom jobs can cost from $20/lineal foot to over $100/lineal foot. We do most of our own work on Uproar, our 42-foot sailboat, but we have had quotes as high as $5,000 for the entire project!

We do our own painting on Uproar. The cost of hauling, bottom washing, bottom sanding, a week in the yard, and relaunching is under $2,000.

The cost of paint is usually $600. By applying the paint ourselves, we save a lot.

13. Are There Special Concerns for Aluminum or Steel Boats?

Yes, any two different metals can cause corrosion.

Proper epoxy barrier coats can prevent the problem, but the manufacturer’s specifications must be followed.

The new, copper-free paints are ideal for Aluminum or Steel hulls.

14. Is There a Bottom Paint for Pontoon Boats?

Epaint even makes a special formula for aluminum pontoon boats.

They also make paint for inflatable dinghies.

15. Where Do I Start?

Talk with other boaters in your location.

Talk with boatyards and charter fleets. You will get a variety of opinions but can determine what would work best for your boat.

If you plan to start living aboard your boat, raise the waterline and paint higher on your hull. Your additional cargo will sink your boat deeper in the water.

Plan your project. Assemble all materials, tools, and protective safety clothing. Prepare a workspace where you won’t accidentally paint your friend’s BMW (ask me how I know). Get help from friends who boat with you.

Wait for the proper weather and be sure to allow proper drying time.

No matter how well you apply your bottom paint, plan on some periodic hull cleaning. This is one project that, if left too long, becomes a nightmare of barnacles and algae.

A clean bottom is essential for boat performance and getting the most enjoyment out of your boating lifestyle.

How Much Does It Cost to Paint a Boat? Updated Price

Written by J. Harvey / Fact checked by S. Numbers

Does your boat look like it needs something fresh for a change? Good paint can be an excellent investment for your vessel. Aside from its aesthetic benefits, it can also protect the walls of your boat. The copper in its color keeps microorganism growth minimal.

You may ask how much does it cost to paint a boat. Is it worth it?

Painting a boat is mostly done by professionals, and this cost can range from low to high prices. Interestingly, there are a lot of options when it comes to making your boat look sleek and brand new again.

What Are the Kinds of Boat Painting?

How much does a boat painting cost, what are the factors that affect the cost of boat painting, can i do a diy painting on my boat, what extra costs should i anticipate for boat painting.

Painting a boat can be a hassle. It can take a toll on you if you do not know the basics.

For starters, painting a boat can consist of bottom painting, topside painting, and both.

Simply, topside painting is furnishing your boat from the water level and above. Bottom painting can mean the other way around: painting it below the waterline when the boat afloat.

Topside Painting

If you are concerned with your boat’s aesthetic look, this kind of painting will boast your favorite color. Your boat can outshine the others if you have the means to coat it with high-standard paint with a unique color.

This kind of painting includes repairs on your boat’s body, preparing the surface, and primer application. It sometimes also consists of the hull , the deck, and the interiors.

One of the main reasons topside painting is necessary is for boat protection with water and sunlight exposure.  

Bottom Painting

As previously mentioned, this kind of painting includes painting the boat below the water level. Hence, not all boats are bottom painted since most boat owners do not consider this practical value. However, your boat can benefit maximally with bottom painting if it is continuously on the dock.

Deck Painting

Most boats with a deck can opt to have their decks repainted and refurbished . This area in the ship can get slippery; hence it may require more frequent repainting than its body. This painting job can stand alone, compared to having the whole topside of the boat painted.

Professional painting is a lot more expensive than doing it yourself. The cost is usually calculated per linear foot. Professional topside painting can range from $100 to $400. On average, it can be around $200.

Bottom painting ranges from $15 to $100 per linear foot professionally. Approximate of $20 is the estimated average for bottom painting.

The range of professional costs for boat painting depends on a variety of factors. You need to consider if this is a repainting job or a brand-new painting project. Here are the factors that might affect the cost of boat painting:

• The bigger the boat, the more surface area is included for professional painters. It also entails more paint to cover the boat’s surface.
• Boat type – The boat’s material is also among the deciding factors that will make painting cost less or more. An aluminum boat has a different painting process than a fiberglass one. The various techniques in between will raise the price.
• Boat condition – the amount of preparation needed to paint the boat can sometimes take more time than the actual painting job. If the ship is slightly wrecked, it may need more refurbishing. This preparation may include sanding, filling, and other possible repairs.
• Paint type – topside painting has a variety of pain types that you can choose from. The premium ones will cost you more.
• The boat’s common location is your ship’s location; if your ship is still on the water, on a trailer, or just in the storage area, will also affect the price. A boat that needs to be hauled may cost higher.

Painting a boat can be done at your convenience with a DIY boat painting. But this activity requires you to know how to prep your boat prior, how to de-stain the surface, how much paint to use, and others.

Doing it yourself can be tedious, but this also means cutting off on the budget. Beyond that, a bottom painting calculator can also guide you on how much paint can be used based on your boat’s size.

Aside from getting a new look for your boat, there are still boat painting preparations that can cost on top of your anticipated fees.  

Paint Stripping

When your boat has worn off its previous paint, most professionals strip the previous paint away. It gives them the chance to inspect for other boat damage. Stripping off the paint entirely also gives the professionals an opportunity to prime it better.

Customization

Some boat owners maximize the painting job for their boat by getting it customized. Aside from the paint, they have their initials, logos, and other customization projects. It may be an additional burden for your pockets, but this painting job adds personality to your vessel. It also features a signature look for your boat on the dock.

The protective benefits of painting a boat are probably why boat owners preserve their boats’ looks in great shape. A high-standard paint keeps the growth of microorganisms at bay. Aside from that, having a unique color makes their boat standout on the docks.

How much does it cost to paint a boat? – Knowing the answer to this question will give you a financial estimate of your expenses in the future.

It considers the health of your boat’s walls and its aesthetic look on its own. The basics of boat painting cost can help you if you want to do it yourself in the future.

If you’re hauling your boat out to the boatyard, whether it’s for maintenance or not, you might want to take the chance to bottom paint it.

Whether you’re bottom painting for the first time or giving it a fresh coat of paint, it’s something that needs to be done every so often, to ensure the boat is being properly maintained. 

Why bottom paint the boat? Well, it’s not like anyone is really going to see the paint underneath, except for the fish under the sea, of course.

But that coating of paint does a great deal to prevent the growth of organisms that will become attached to the hull, and then decrease the overall performance of the boat. So basically, you need that coating of bottom paint. 

Since you have to bottom paint your boat, you’re going to have to see how much it costs, and budget appropriately so you can get it done along with the rest of boat maintenance.

Whether you’re hiring a professional or doing it yourself, let’s break down all the costs involved in the bottom painting of the boat, on average. 

Table of Contents

Average costs to bottom paint a boat: DIY and professional

The cost of bottom painting your boat can of course vary, as it can depend on many different factors, including the type of paint and the size of the boat.

Average prices can range from $300 to over $3000, so there’s quite a big difference depending on how big the boat is, and the quality of the paint that you choose. 

It seems rather expensive for a paint job, but the paint used in boats needs to be able to withstand saltwater and other elements, so it’s rather pricey!

Not to mention that painting the bottom of a boat is a little more complicated than painting something like a wall in a room. 

If you want to get a good price, you can research different professional companies and see which one offers the best deal. Or if you want to save some money, you could just pull a DIY and get the job done yourself! 

Let’s look at the average costs for both options: 

• Hiring a professional company:

Usually, professional companies will have set prices according to the size of the boat, so they will charge you accordingly. Although sometimes, they can have deals or offers in place, so it’s worth doing some research and comparing different options. 

On average, hiring a professional company to bottom paint your boat will cost between $1000 and $3000 or more. Again, it depends on the size of the boat. 

• Doing it yourself:

Bottom painting your boat in a DIY manner will save you some money, but you need to have the right materials, and you need to be confident in your skills so that you’re sure of being able to do a good job.

You’ll be saving on the labor, but you’ll still have to pay for the paint, so the price will range between $300 and $2000 on average, depending on how much you need. 

Estimating the cost to bottom paint a boat:

We now know the average costs of bottom painting a boat, but as we mentioned, the price completely depends on the size of the boat and the paint you’re using, so the estimated cost varies from boat to boat accordingly. 

How can you estimate a more accurate cost for your specific boat? Well, let’s take a look, whether you’re hiring a professional, or doing it yourself.

• Estimating the cost with a professional company:

Most commonly, the professional company will provide you with an estimate of the cost, before the job begins. Meaning you have the chance to accept and agree on that price, or reject it and look for another option. 

They will provide you with an estimate once you’ve given them the information about your boat, which will include the size in feet length.

They might also provide you with different paint options, but they’ll make you aware of the differences in price between them beforehand. 

• Estimating the cost when doing it yourself: 

When you’re estimating the cost yourself, it’s not as simple as providing the measurements for the boat, choosing paint, and then getting a quote. Instead, you’re going to have to do the maths yourself, and figure everything out.

So what things are you going to have to take into account, towards the final overall cost? Here is a list of the basics that you need to consider: 

• Measure your boat fully, so you know exactly how much paint you will need. You need to measure the length, the width, and the height, so you have the entire bottom of the boat covered. 
• Once you know how much paint you need, you have to look for a paint option, look at its price, and calculate what the overall cost will be for paint. This will be the big bulk of your overall cost for the whole job. 
• You will need other materials, other than paint, and getting these will factor into the final cost as well, as you will have to buy whatever you don’t have. Items such as a respirator, a spray gun , sandpaper, paintbrushes, and others. Basically, all of the tools needed to perform the job. 
• If you’re going to hire a helping hand, so that you’re not doing the entire job by yourself, then you will also have to pay them for their labor, unless you have a friend or family member willing to help for free! 

How to estimate the cost of paint for bottom painting a boat: 

The paint is the biggest bulk of the cost when it comes to bottom painting your boat, so it’s important that you’re able to estimate its cost as accurately as possible.

We’ve already mentioned that you need to measure your boat, width, length, and height, in order to know how much paint you need, but let’s look at it in more detail. 

Once you’ve calculated the square feet of the bottom of your boat, you know how much you need to cover. But how much paint does each square of food require?

Well, if you’re only applying a single coat of paint, you can cover around 25 to 30 square feet with 1 gallon of paint. Likewise, you can cover around 40 square feet with 2 gallons of paint, and around 50 square feet with 3 gallons of paint. 

However, it is usually recommended that you apply at least two coatings of paint to the bottom of your boat, to stop it from wearing off too quickly. This means you will need twice the amount of paint. 

The average cost for the paint used for bottom painting a boat is usually between $100 and $150 per gallon. So you can see how the job can get pricey pretty fast. 

You also then need to consider the use of a primer paint, and of a finishing coat, both of which will further add to the overall cost. But, of course, this is optional and up to you.

Although a lot of the time, it can depend on the paint you’re using, as some will have to be sealed with a gel coat layer in order to be effective. 

How to estimate the cost of labor for bottom painting a boat: 

Estimating the cost of the labor is done by estimating the amount of hours it will take to complete the job, and then calculating the cost with the price of the labor. 

If you’re hiring a professional company, you don’t have to worry about how much you’re paying for the labor itself, because it’s included in the service, and the price is instead calculated based on the size of the boat. 

But if you’re doing it yourself, you might want to consider hiring some helping hands to get it done quicker. And if not, it’s still good to know how many hours, roughly, bottom painting your boat will take, so that you’re aware of the time it requires. 

Maybe we should have named this section ‘how long does bottom painting a boat take’, but let’s go ahead and figure that out. 

Well, the truth is, it can’t really be estimated in an accurate way, because it depends on how fast you’re painting! But on average, most bottom paint jobs for boats take between 10 and 50 hours of time.  Let’s break down an average bottom paint job:

• Preparation: 

Before you start painting, you need to prepare the bottom of the boat. You have to tape off the borders, ensure the boat is well positioned, and ensure the conditions are right.

If you’re able to paint indoors, it shouldn’t be a problem. But when outdoors, the weather can get in the way of the job. Ideally, it should be sunny and warm, so that the paint can dry faster. 

This preparation stage might also include sanding down the boat or cleaning up the residue from previous paint jobs, before you apply the new one. It can be quite some time before you can actually start with the painting!

• Primer coat:

The primer coat sets the base upon which you can apply the actual coat of main paint. Usually, it’s recommended that you apply two layers of primer, to ensure there’s enough of it. Once you’re done, you need to wait until it’s dry before proceeding onto the next stage.

The base coat needs to be applied with patience and taking your time. Rushing it risks doing a bad job, and you might not end up giving the boat the protection it needs for a long lifespan. 

It is completely recommended that you apply two layers of paint, and you will have to leave the first to dry before starting on the second one, so this might take quite some time. Once you’re done, you need to wait until it’s dry before proceeding onto the next stage.

• Gel coat: 

The gel coat is often used to seal the paint in place, and to offer an extra layer of resistance that ensures that the paint is durable, and that the bottom of the boat is well protected.

It is also recommended that you apply two layers, but it’s up to you, and it depends on the paint you’ve used. Once you’re done, you need to wait until it’s dry before proceeding onto the next stage.

• General check-over: 

The general check-over is basically ensuring that you’ve covered the entire surface correctly, and that everything is in order. You then need to wait the specific amount of time, stated in the paint you’ve used, before the boat can return to water. 

The amount of time it takes for you to paint the bottom of the boat depends on your own speed. However, there is a specific amount of time that you need to allow for while each coating of paint is left to dry.

This amount of time can vary depending on the type of paint used, and can range between 10 minutes to overnight. 

In Conclusion

Let’s sum this up, how much does it cost to bottom paint a boat? On average, it can cost anywhere between $300 and $3000.

The main factors that determine the cost of the job are the size of the boat (which determines the amount of paint needed), and the type of paint that you will use (which determines the price of the paint needed). 

There are other factors, such as the price for labor (which varies depending on if you’re hiring a professional company, or if you’re doing it yourself), the tools needed for the job (if you have them already it will be cheaper, but if not you will have to buy them), and any other costs that might arise during the process.

Topside Painting

Topside painting refers to painting the upper part of the boat, including the deck, cabin, and superstructure. This is usually done with a two-part polyurethane paint, which is durable and resistant to fading. The cost of topside painting depends on the size of the boat, the quality of the paint, and whether a professional is hired.

Hull Painting

Hull painting refers to painting the bottom of the boat. This is done with a specialized paint that is designed to withstand saltwater and other elements. The cost of hull painting depends on the size of the boat, the quality of the paint, and whether a professional is hired. It is also important to note that the old paint must be removed before applying new paint, which can add to the cost.

Paint Quality

The quality of the paint used affects the cost and the longevity of the paint job. High-quality paints are more expensive, but they last longer and provide better protection against the elements. Cheaper paints may save money in the short term, but they may need to be repainted sooner, which can end up costing more in the long run.

Paint Application

The method of paint application affects the cost and the quality of the paint job. Brush and roller application is the most common method, but it can be time-consuming and may leave brush marks. Spray application is faster and provides a smoother finish, but it requires more skill and can be messy. The method of paint application depends on the type of paint being used and the size of the boat.

In conclusion, painting a boat requires proper preparation and execution. The cost of painting a boat depends on various factors, including the size of the boat, the quality of the paint, and whether a professional is hired. It is important to choose high-quality paint and to use the proper method of paint application to ensure a long-lasting and durable paint job.

Some boat painting companies may charge by the linear foot, which is the measurement of the boat’s length. The cost per linear foot may range from $2 to $400. The cost may vary depending on the boat’s type, size, and whether the owner chooses to paint the topside or bottom.

Cost per Square Foot

Some boat painting companies may charge by the square foot, which is the measurement of the boat’s surface area. The cost per square foot may range from $10 to $25. The cost may vary depending on the boat’s type, size, and whether the owner chooses to paint the topside or bottom.

Overall, the cost of painting a boat can vary significantly depending on various factors. It is essential to consider all relevant factors before starting the painting process to avoid any unexpected costs.

Special Considerations for Different Boat Materials

When it comes to painting a boat, the material of the boat plays a significant role in determining the cost and the type of paint that should be used. Here are some special considerations for different boat materials:

Fiberglass boats are the most common type of boats, and they require special care when it comes to painting. The gel coat on fiberglass boats tends to wear out over time, which can lead to cracks and other forms of damage. Before painting a fiberglass boat, it is essential to repair any damage to the gel coat. This can be done by sanding the damaged area and applying a new gel coat layer. After the gel coat is repaired, the boat can be painted. It is recommended to use a marine-grade paint that is specifically designed for fiberglass boats.

Aluminum boats are lightweight and durable, making them a popular choice for boaters. However, painting an aluminum boat requires special considerations. The surface of the aluminum must be cleaned and prepped before painting to ensure that the paint adheres properly. It is also important to use a paint that is specifically designed for aluminum boats to prevent corrosion.

Wooden boats require special care when it comes to painting. The wood must be sanded and prepped before painting to ensure that the paint adheres properly. It is recommended to use a marine-grade paint that is specifically designed for wooden boats. Additionally, it is important to ensure that the boat is properly sealed to prevent water damage.

Gel coat is a protective layer that is applied to fiberglass boats. Over time, the gel coat can become damaged, which can lead to cracks and other forms of damage. Before painting a boat with damaged gel coat, it is important to repair any damage. This can be done by sanding the damaged area and applying a new gel coat layer. After the gel coat is repaired, the boat can be painted. Click the link for more information on repairing gel coat damage on a boat .

In conclusion, when it comes to painting a boat, the material of the boat plays a significant role in determining the cost and the type of paint that should be used. It is important to take special considerations for different boat materials to ensure that the paint job is done correctly and lasts for a long time.

DIY Boat Painting Vs. Hiring a Professional

When it comes to boat painting, there are two options: DIY painting or hiring a professional. Each option has its pros and cons, and it’s up to the boat owner to decide which one is the best fit for their needs.

DIY Painting

DIY boat painting is a popular option for boat owners who want to save money. The cost of paint and supplies can range from $400 to $1,000, depending on the size of the boat and the quality of the paint. If the boat owner has experience with painting, they may be able to complete the project on their own. However, if they don’t have experience, it’s important to do research and follow instructions carefully to avoid mistakes.

One advantage of DIY boat painting is that the boat owner has complete control over the project. They can choose the paint color and type, and they can work on the project at their own pace. However, it’s important to keep in mind that DIY painting can be time-consuming and labor-intensive. The boat owner will need to set aside several days or even weeks to complete the project.

Hiring a Professional

Hiring a professional to paint a boat is the most expensive option, but it also has its advantages. A professional company like a body shop will cost anywhere from $1,000 to $5,000 or more, depending on the size of the boat. The advantage of hiring a professional is that the boat owner doesn’t have to do any of the work. The professional company will handle everything from preparing the boat for painting to applying the final coat.

Another advantage of hiring a professional is that the boat owner can be sure that the job will be done correctly. A professional painter has the experience and expertise to ensure that the paint job is smooth and even, and that the paint will last for years to come. Additionally, hiring a professional can save time, as the job can be completed in a matter of days rather than weeks.

When deciding whether to paint a boat themselves or hire a professional, boat owners should consider their budget, time constraints, and level of experience.

How Much Does It Cost to Bottom Paint a Boat? (& More)

TheToolGeeks.com is a participant in the Amazon Services LLC Associates Program and other affiliate advertising programs.    We may earn from qualifying purchases.  ( Learn More ).

Before embarking on any painting task, one primary factor that influences all others is the total cost of the task.

The cost will determine your method of approach to carry out the task, the materials you will get, and if you will hire a professional or not. The same is the case when you want to paint the bottom of your boat. So it’s normal to wonder how much it will cost.

On average, the cost to bottom paint a boat by yourself ranges between $300 to $2000. If you hire a professional or employ the services of a boat-painting company, the total cost will be between $1000 to about $4000. Of course, these are just estimated amounts.

The cost to bottom paint your boat might be more or less than the amount stated above due to several factors such as the condition of the boat, the quality of paint to be used, and the size of the boat amongst others. For instance, it will cost more to bottom paint a 30-foot boat than it will cost to paint the bottom of an 18-foot fishing boat.

Overall, knowing how much it will cost you to bottom paint your boat will help you make better financial decisions. So how do you estimate the cost? What type of paint should you use to bottom paint a boat? And when should you hire professional help?

You see there is a lot more to know about bottom painting your boat and this post will introduce you to all you need to know about the process. So let’s get on with it.

What Does It Mean to Bottom Paint a Boat?

To bottom paint a boat means applying coats or layers of paint to the hull or bottom of a boat. The paint serves as a cover to the bottom frame of the boat to prevent it from damages that can hamper the boat’s performance. Apart from beautifying the hull material of the boat, the paint serves as a protective shield to the hull of the boat too.

The bottom part of a boat suffers from intense friction and moisture. Regardless of whether the hull of the boat is made from wood, metal, aluminum, or any other material, the hull needs to be protected. Most of the time, your boat will be in the water.

When it’s not in the water, the boat is on the harsh sand of the shore, or in the back of a trailer when it is being transported. It is the bottom part of the boat that suffers from the coarse nature of the sand, the salty and bacteria-infested nature of the water as well as the steel frame of a trailer.

Without a hard coat of paint, the bottom part of the boat will experience scratches, dents, cracks, and holes. Not to mention the activity of different organisms in the water like algae, barnacles, and bacteria.

All of which will hamper the speed and performance of the boat in the long run. If the frame starts to crack open, it will also become very difficult for the boat to stay afloat.

This is why the bottom part of the boat is usually painted so the durability of the boat can be improved.

What Factors Determine the Cost to Bottom Paint a Boat?

Painting the bottom frame of your boat will cost you some cash but the amount of cash you will spend depends on the following factors.

• The Size of the Boat –  The bigger your boat, the more paint you will use and the time it will take to paint it. Extra gallons of paint equal extra cash and I’m sure you have heard of the cliché “Time is money.” For instance, it will cost you more to fully paint the bottom of a 35-foot boat than it would cost for an 18-foot boat.
• The Paint – You can’t use the normal latex or oil-based paint meant for walls to paint the bottom part of a boat. This is because these paints are not designed to be used in water. The paint needed for the bottom part of a boat needs to be able to cope well with the salty nature of the water and it must be able to resist the activity and growth of organisms that attach themselves to the boat. Antifouling paint is usually advised because the paint is specially designed for marine life.
• The Labor Used – Painting the bottom part of your boat by yourself will cost you less than hiring someone or contacting a boat-painting company to paint it for you.
• The Tools Needed – To paint the bottom of a boat, the boat needs to be elevated or suspended above ground level. You will also need additional tools and materials like sandpaper, scrappers, a primer, and the likes. All of which will spike the total cost eventually.

That being said, let’s check out how to calculate how much it will cost to paint a boat.

How Can You Calculate the Cost of Bottom-Painting Your Boat?

Painting the bottom part of your boat can be done in two ways. You can do it yourself or employ the services of a professional boat painting company. The cost to bottom paint your boat will depend primarily on the method you decide to use.

The Cost of Hiring a Professional Boat-painting Company

If you want to employ the services of a boat painting company, the estimate would be made known to you by the company. Usually, they will require you to provide the size dimension of your boat or take the measurements themselves.

The Cost of Painting the Boat Yourself

If you want to paint the bottom of the boat yourself, then you will need to do more than just provide the size dimension of the boat.

In addition to the size dimension of the boat, you will need to buy a few materials, rent a few tools, and depending on the size of the boat, you might need to hire an extra set of hands to help you out.

Regardless of the method, one similar need of both methods is the size dimension of your boat. The size dimension will determine the amount of time and paint you will use. So let’s check out how you can get the size dimension.

How to Measure the Size Dimension of a Boat?

The size dimension of your boat refers to the width, height, and length of the boat. To measure these, you will need:

• A tape rule
• A pencil and paper.

To get the size dimension of your boat, use a tape rule to take the measurements and write them down on a piece of paper.

Be mindful of the curves and corners of the boat while you take the measurement. The best way would be to measure along the curves to get an accurate measurement especially for the height of the boat.

For the width, measure the length of the widest part of the boat. The widest part is usually around the middle of the boat.

For the length, measure the distance from one end of the boat to the other and write down the measurements.

To be sure you have the accurate size dimension, you can search for the size dimension of the model (the type of boat) you have online and crosscheck what you see online with what you measured.

Let’s check out other factors that will determine the total cost to bottom paint a boat aside from the size dimension.

The Cost of the Tools Needed to Bottom Paint a Boat

If you want to bottom paint the boat by yourself, asides from the size dimension, you need to get a list of the tools you will need to successfully bottom paint your boat.

If you want to hire a professional boat painting company, then you don’t need to worry about the tools because the total cost will be made known to you.

However, if this is a DIY task for you, then the cost of the tools and materials you need will affect the total estimate.

To bottom paint a boat by yourself, you will need:

• For the hull of a boat, you will need to buy coarse sandpaper.
• A paintbrush, roller, or paint sprayer
• Paint trays
• A pair of work gloves, safety goggles, and a respiratory mask
• A scrapper to get rid of barnacles and other attachments to the bottom of the boat
• Masking tape and drop cloths

The Cost of the Paint

The cost of the paint for the hull of a boat is usually more costly than the cost of your regular latex, acrylic, or oil-based paint.

This is because the paint used for the bottom of a boat has to be moisture resistant, able to withstand a lot of friction, and has to be capable of curbing the growth of organisms on the boat. Usually, antifouling paint is recommended for the hull of a boat. The paint is specifically designed for the outer layer of boats so it will work well underwater.

Other paint types include ablative paint which is designed to wear off slowly, Hard-bottom paint which is best for speed boats, and Polyurethane paints.

Regardless of the type of paint you go for, expect to spend more than you would ordinarily spend on a bucket of latex paint for walls.

Hull paints are usually sold in one-gallon containers and the price can range from as low as $30 to over $200 per gallon. The price will depend on the paint you decide to get.

It’s advised to go for quality in this case as bad paint will ultimately expose the frame of the boat to damages and aquatic organisms. The size of your boat will also determine how many gallons of paint you will need and the number of coats required.

Below is an estimate of the gallons needed according to the size of the boat.

• For boats that are between 18 – 35 feet, a single coat of paint will require one 1½ gallon of paint while a double coat of paint will require 3 gallons of paint.
• For boats that are between 36 – 51 feet, a single coat of paint will need about 3½ gallons of paint while a double coat will require about 6 gallons of paint.
• For boats that are between 52 – 63 feet, a single coat of paint will need about 4½ gallons of paint while a double coat will require about 9 gallons of paint.

The bigger the boat, the more gallons of paint needed.

The Cost of Prepping and Repairing the Bottom Part of Your Boat

When attempting to bottom paint your boat, you will notice dents, cracks, and other damages to the hull of your boat. These damages would need repairs so the new paint can stick to the surface properly and so that the water wouldn’t affect the paint when sailing.

You will also need to prep the hull before painting. This will require you to scrape the barnacles and bumps off the bottom of the paint.

This can take hours depending on how hard the barnacles are. You will also need to prime the hull to increase its adhesiveness.

The cost of repairing and preparing the bottom part of the boat can be as high as $500 depending on the size of the boat and the extent of the damage.

It can even cost more than that if you have to replace a damaged part of the boat’s hull. Of course, this is for when you want to do it yourself.

Hiring a professional boat painting company will cost more. These companies charge per linear foot of the boat and the price will cost between $30 to over $120 depending on the size of the boat.

That’s just the price for painting. Boats that need additional repairs will cost more than that. For boat painting companies, there is also an additional cost for storing and transporting the boat before and after painting.

Of course, these prices will also vary based on your location and the type of paint job you want. For instance, premium hull painting will cost more than basic hull painting.

How to Calculate the Estimate to Bottom Paint a Boat?

The estimate for bottom painting your boat will depend on if you decide to DIY or hire a boat painting company.

If it’s a company, then the overall cost will be made known. The challenge is when you want to do the task yourself. You will need to do a lot of calculations for this.

For instance, let’s calculate the estimated cost of painting a 30-foot boat by yourself.

Let’s assume,

• You buy two gallons of antifouling paint for $70 each. That will cost you $140.
• You buy a can of primer for about $20 since priming is advisable to increase adhesiveness.
• You will need to prep the bottom of the paint which will require you to scrape bumps and barnacles. Then sand repeatedly using sandpaper. To scrape off barnacles, you will need a metallic putty knife or spatula and sandpaper to sand. The cost of buying these can be up to $50.
• You might need to transport your boat from one location to the other and also rent tools that will help you elevate the boat so you can work underneath. Both will cost you well over $100 depending on your location.

That’s already a total price of over $300 and that’s without calculating the cost to repair damages, hire help, and store the boat if needed.

When you put the following into account, the total price can spike up to $500 and for a boat painting company, the final cost can be up to $1000. While painting the hull of a boat, do not spare any expense as this isn’t a task you would want to sacrifice quality for cost.

Should You Bottom Paint a Boat Yourself or Hire a Professional?

While I will advise you to paint walls , floors, and other objects by yourself, I wouldn’t advise you to paint the bottom part of your boat by yourself. This is because so much can go wrong if you are inexperienced not least the risk of suffering life-threatening injuries if the boat isn’t firmly elevated. If it’s your first time, you should hire a professional for the sake of safety and efficiency.

Inadequate experience with this type of task and the absence of the required tools and materials will result in a bad paint job and possible injuries.

So I would advise you to hire a professional or a boat-painting company. If you would like to have hands-on experience with painting the bottom part of your boat, then you can hire a professional to assist you.

That way you will gain some valuable experience and know-how to embark on such projects the next time you want to paint the bottom part of your boat.

If you have any questions or comments about bottom-painting your boat, you can leave them below and I will attend to them as soon as possible. Have a nice day.

How Much Does It Cost to Paint a Boat? Updated Price

Written by Anthony Roberts / Fact checked by Jonathan Larson

Seeing your boat with a worn-out look obliges you to have a painting job done. A price comes along with the upgrades that you want to make. So you would ask yourself, ‘How much does it cost to paint a boat?’.

If you choose to avail of professional services, the topside painting costs $100 to $400 per linear foot, while the bottom painting varies from $15 to $100 per linear foot. Doing it DIY has an estimate of $2 to $10 per square foot.

This article will show you more details regarding the expenses when painting a boat. You’ll know which works for you; hiring a professional or doing it yourself.

Table of Contents

Factors that Affect the Professional Cost of Boat Painting

What you need to know when hull painting is done by professionals, extra cost when hiring professionals for boat painting, example calculation for diy boat painting.

There’s a difference between painting a brand new boat and repainting. It’s just one of the several factors that affect the cost of boat painting. Bear in mind that you sometimes need to spend some bucks for preparations before new coatings are applied.

To be aware of the future expenses, here are the other factors:

• The total cost of the painting job varies from boat to boat. By nature, a bigger boat has a wider surface. So you need to spend more as it necessitates a larger amount of paint than a smaller vessel.
• The boat’s material is another factor that determines the price you’ll pay for the painting job. For instance, the process of painting an aluminum boat is different from a fiberglass one . As a result, a more complex technique, a higher fee is charged.
• There will be necessary preparations before painting the hull and they sometimes take more time than the painting job. Well, it depends on the boat’s condition and how bad it is.

Some require refurbishing, filling, sanding, and other types of repair. These procedures are not free so expect additional charges.

• There are various paints to choose from and they are sold at different prices. Pick the one that is suitable for your boat’s material.
• The location of your boat also affects your spending on painting your boat. For example, your boat may be in a storage area, on the water, or a trailer. The need to haul it asks for an extra fee as well.

The base cost of hiring professionals mainly depends on the boat size. In this case, based on the latest professional painting rate, every linear foot for premium selections starts around $100 to $125.

The basic procedures start at $25. This rate applies to virgin hulls or those that haven’t been painted as they don’t require paint removal.

A professional boat painter typically needs 10 to 40 hours to finish the whole boat. However, there’s no need to count the time and attempt to sum up the total cost.

You’ll receive an estimation of the painting cost from the professionals before they begin the job. It’s convenient for boat owners as they only need to decide if the price is right. If not, there’s leeway in finding a better option.

The total price can be estimated after you’ve given the information about the boat, such as size in feet and its current condition. You’ll also be given a chance to pick among various kinds of paint and the price range.

Some professionals will give you an insane bid if they know that you have boat insurance. They also charge higher costs if they have a hectic schedule. You should know these things as a boat owner to have your say in this matter.

Here are some estimates that can be done by a professional. But, of course, it may vary as it depends on your boat size and the usual charges in your location.

l 29’ boat = $25 per linear foot + $155 for premium upgrades

l 30’ to 36’ boat = $29 per linear foot + $190 for premium upgrades

l 37’ to 43’ boat = $34 per linear foot + $250 for premium upgrades

l 44’ to 49’ boat = $38 per linear foot + $330 for premium upgrades

l 50’ to 54’ boat = $43 per linear foot + $400 for premium upgrades

l 55’ to 59’ boat = $49 per linear foot + $490 for premium upgrades

l 60’ and larger boats = $56 per linear foot + $555 for premium upgrades

In some cases, your boat needs to go through some processes before obtaining a new look. So there might be an extra charge on top of the given estimation.

Paint Stripping

The previous paint needs to be stripped off before applying a new one. It will also give the professionals a chance to inspect your boat for damages if there’s any. Furthermore, it gives them a much better way of priming your watercraft.

Customization

If you want to give your boat an outstanding look, you should be willing to spend more on customization. Your initials, logo, and other things can be added aside from the new coating. It’s worth spending on this as it gives your boat that signature look.

Estimating the Cost of DIY Boat Painting

When you choose to skip professional fees and handle boat painting by yourself, you should know the essential steps. They usually involve doing the math but it’s not only about numbers but discretion too.

Here are the steps you shouldn’t skip to correctly come up with the price you need for a newly painted boat.

• Get the whole measurement of your boat to know the exact amount of paint that you’ll need. Take note of the length, width, and height. Be attentive when obtaining the numbers as it’s the biggest bulk of the overall cost.
• After you’ve finalized the quantity of paint that will cover the entire boat, you will need to search for the right type of paint. Know the price of the type of paint you’ve picked to come up with the necessary amount.
• Some materials are needed to complete the job and you have to buy them when they’re not on hand. Spare some amount for a spray gun, respirator, paintbrushes, sandpaper, and more.

You will need $50 to $200 to buy these things to help you achieve a satisfactory result.

• You may also need assistance which conveys another fee. On the brighter side, it won’t cost you if it’s your friend or family member who’ll lend you a helping hand.

Boat Paints and Number of Coatings

Be particular of the following points as they’re known as the boat paints.

• Anti-fouling paint
• Polyurethane
• Oil-based (for top part)
• Gel coat (for outer layer)
• Tar points (as bottom paint)

Water vessels vary not only because of their types but with the materials. Therefore, a specific paint is compatible with each of them. Also, the suitable paints for the interior and exterior are different.

To set an example, an affordable anti-fouling paint adheres well on old wooden boats. So when you have a speedboat that’s made of IMG composites, choose the best among the best boat paints, and of course, it will be costly.

Ablative hull paints are usually applied for two coatings, while the modified epoxy is fine with a single stroke. Here are some tips to make a calculation of the total cost for paint easier.

l 20’ to 35’ feet = 1 1/2 gallons (single coat)

l 20’ to 35’ feet = 3 gallons (double coat)

l 36’ to 51’ feet = 3 1/2 gallons (single coat)

l 36’ to 51’ feet = 6 gallons (double coat)

l 53’ to 63’ feet = 4 1/2 gallons (single coat)

l 36’ to 51’ feet = 9 gallons (double coat)

For example, you can only spend a sum of $420 for an 18-foot boat, $360 for quality paint and $60 for the materials.

An 18-foot boat is equivalent to 222 square meters. If you divide 222 square meters to the total cost of $420, it will give you $1.89 square meters. See? It’s affordable as long as you have the patience and skills to paint your boat.

Sailing through different bodies of water exposes your boat to different outdoor elements. That’s why protective coating through the proper application of marine-grade paint is very important.

By being careful about your actions and thinking about ‘How much does it cost to paint a boat?’, you’ll be aware of the possible expenses. In specific conditions, it will leave you always prepared for the maintenance of your boat.

How Much Does It Cost to Bottom Paint a Boat?

Maintaining a boat is an ongoing task that includes many different activities to keep the boat in good shape and working well on the water. One important maintenance job is bottom painting. 

This isn’t just about making the boat look good, but more about protecting the lower part of the boat from water damage and things like algae and barnacles that can stick to the boat and slow it down. How much does it cost to bottom paint a boat?

A general guideline to consider when estimating the cost of bottom painting a boat is to allocate around $100 to $150 per linear foot. 

Taking an example of a 26-foot boat, you could expect the cost for a quality bottom paint job to fall between $3,250 and $3,900 including all the additional labor costs and materials.

Do you know:

In a $2.4-million study commissioned by Transport Canada, a novel hull paint originating from Nova Scotia was found to deliver remarkable results for fishing boats. This innovative paint not only reduced fuel consumption by an impressive 20%, but it also significantly lowered vessel noise levels by six to seven decibels.

The cost of antifouling bottom painting a boat varies based on different aspects which include the boat size, the quality of paint utilized, and no matter if you decide to do it yourself or get it done by experts. There are many choices! Here’s a breakdown of the costs you might incur: 

The cost of hiring a professional company to paint a boat can vary widely depending on various factors such as the size of the boat, the type of paint used, the condition of the boat, and the region or marina where the work is being done. 

Professional services generally charge by the linear foot, with costs ranging from $100 to $150 per linear foot. However, this rate can be higher in certain regions or marinas, or for highly experienced professionals.

For an average boat of 20 feet, you might need to set aside from $2,500 to $3,000, but costs can reach upto $5,000 depending on the various factors;

• Condition of the Hull
• Type of Paint
• Labor Costs
• Additional Services
• Geographic Location
• Choice of Professional Service
• Environmental Regulations

The cost of professional bottom painting can also be estimated based on the boat’s length:

Boat maintenance labor costs, particularly for painting, may surprise new owners. A quote like $35 per foot often covers estimated labor, with additional charges possible for unexpected issues. Responsible marinas typically communicate extra costs resulting from unforeseen work.

The overall labor expense varies based on the boat’s size and the job’s scope. A professional may dedicate 10-20 hours to bottom painting, with labor rates ranging from $50 to $100 per hour.

Some professionals charge by the square foot, with rates typically ranging from $15 to $25 per square foot. For example, if your boat has a bottom surface area of 300 square feet, you might be looking at a labor cost of $4,500 to $7,500 at these rates.

There could be additional labor costs if the boat needs extra preparation work before painting. This might include sanding , scraping off old paint , or repairing any damage to the hull. Professionals might charge an hourly rate for this type of work, often ranging from $50 to $100 per hour.

If you decide to undertake a bottom painting project on your own, using a single-stage polyurethane paint followed by a gel coat or ‘hot coat’ for an added layer of shine and protection, the costs can vary widely based on the size of your boat and the quality of paint you choose.

The typical cost range for a DIY bottom painting project can be anywhere from $300 to $2000. 

This cost primarily covers the paint and the gel or hot coat, but the expense can rise if you select higher-end materials designed to provide superior protection against saltwater and other marine elements. 

The bottom paint might be priced higher compared to topside paint due to its specialized formulation designed to withstand harsh marine conditions.

Selecting the appropriate paint for bottom painting a boat is important for guarding against marine growth and corrosion. Usually, antifouling paints are used to prevent the buildup of organisms on the boat’s hull.

These paints often incorporate biocides to discourage marine life. However, it is recommended to seek guidance from professionals or consult the boat paint manufacturer’s recommendations for the most suitable product based on your specific boating conditions and preferences.

Boat painting typically involves these steps, as mentioned below:

Epoxy primer is tough stuff and works great for patching up fiberglass because it dries hard. Moreover, such a surface can serve as an ideal foundation for applying additional layers of paint.

These primers are an excellent choice for making repairs and preparing the boat’s surface for paint. They provide a strong, moisture-resistant foundation that improves adhesion of topcoats. They’re typically used on fiberglass and metal surfaces to prevent corrosion and water damage.

Barrier coats are ideal for preventing osmosis in fiberglass hulls. They create a protective shell that blocks water penetration, which is important for maintaining the integrity and longevity of your boat. They also provide a smooth surface for applying antifouling or topside paint, making them a good first step in the painting process. 

Ablative paints are great for boats that are used frequently. Over time, it wears off slowly, making it harder for nasty critters like barnacles to stick to your boat. 

It’s a low maintenance choice as it self-polishes and doesn’t build up layers over time. 

Antifouling paint is specially designed to prevent the growth of marine organisms on a boat’s hull. It creates a smooth, protective barrier that inhibits barnacles and algae, enhancing a boat’s performance and fuel efficiency.

The one-part polyurethane paints are a go-to for many due to their ease of application and durability. They give a high-gloss finish that’s resistant to staining and abrasion. 

They are also easier to clean compared to other types, making them a user-friendly option for new boat owners. 

Gel coat is a protective layer applied to the boat’s surface. It shields the boat from environmental elements. Combining antifouling paint and gel coat ensures a well-maintained and clean vessel, prolonging its life and maintaining its aesthetic appeal. These two components are fundamental for any boat owner.

Bottom painting a boat with antifouling paints is typically unnecessary in two primary scenarios. Firstly, if you store your boat on a trailer, lift, or in a dry storage facility, rather than keeping it in the water for extended periods, there may be no need for bottom painting. In such cases, the boat is not exposed to the conditions conducive to the growth of marine organisms on the hull.

Secondly, if your boat is consistently stored out of the water, such as on a trailer or in dry storage when not in use, using bottom paint might not be necessary. This is because regular maintenance becomes more manageable, and you can easily remove any aquatic growth that may occur between uses.

In both situations, the crucial factor is the absence of prolonged water exposure, minimizing the risk of fouling. As a result, bottom painting becomes unnecessary, allowing boat owners to concentrate on other maintenance aspects without requiring antifouling treatments.

Boat owners apply bottom paint to the submerged portion of their vessels for various crucial reasons. Firstly, the practice of anti-fouling, utilizing paints with specific chemicals, deters the accumulation of marine organisms like barnacles, algae and seaweeds. This not only maintains the boat’s performance by preventing drag but also ensures a more efficient and streamlined movement through the water.

Moreover, bottom paint serves as a protective shield against corrosion. Continuous exposure to water can result in rust and various forms of corrosion, especially for metal hulls. By applying this protective coating, boat owners significantly reduce the risk of structural weakening over time.

The enhanced efficiency of a smoothly painted hull contributes to fuel efficiency, a vital factor, especially for larger vessels with significant fuel costs. The reduction of friction as the boat moves through the water translates into tangible economic benefits.

In addition to functional advantages, the aesthetic aspect also plays a role in bottom painting. Many boat owners choose to paint the hull for personalization and visual appeal.

Notably, antifouling paint is crucial for preventing wood rot, especially in boats exposed to water year-round or during extended anchor periods. Maintenance intervals vary, with an annual bottom painting recommendation for boats in constant use, and a 2-3 year interval for those in and out of the water.

Bottom painting is an important step to keep your boat safe and smooth on water. Whether done by a professional or by yourself, it requires a good amount of money, but it’s a worthy investment. The cost depends on your boat’s size, the paint quality, and who does the job. 

Each paint type has its own price, and you may need to pay extra for fixing any damage before painting. Though it may seem a lot, learning and estimating how much does it cost to bottom paint a boat ensures it stays in good shape for your water adventures.

The time it takes to paint the bottom of a boat can change based on how big the boat is and who is doing the painting. Usually, it can take 7 to 10 days to finish the job. The kind of paint used can also affect the time because some paints take longer to dry.

Bottom painting a boat is beneficial, especially to protect it from the effects of saltwater, which can cause oxidation leading to a change in the hull’s color. For pontoon boat owners, it’s a familiar issue as oxidation occurs fast when the boat stays in water. Fiberglass boats too can face oxidation, making bottom paint a good idea for all boat types.

Bottom paint can reduce your boat’s speed. If your boat’s hull has a smooth, untextured paint finish, the impact of this issue may not be very noticeable. However, if you’ve been applying multiple coats of ablative paint yearly and the boat hasn’t been used much, the accumulated layers can cause a slowdown.

In freshwater settings, a particular kind of paint is needed for your boat, often referred to as antifouling bottom paint. There are several benefits to using this paint, making it a key topic for those new to boat maintenance.
