4 Maintenance and Troubleshooting
5 Conclusion

The summer months of the year bring hours of sunshine, giving boaters plenty of time to explore during the day. When the sun sets, safety becomes a priority for anyone operating a boat in the dark. It’s crucial to know which boat lights must be on and how to stay visible and safe while sailing at night.

We’ll provide all the essential information you need to make sailing at night a safer and more enjoyable experience. You’ll get an overview of the different types of boat lights available and tips for staying safe and visible while sailing in the dark.

Safety Considerations

Safety should always be the top priority of any sailor, regardless of the time of day. When boating at night, you must know the rules and regulations in your designated area and familiarize yourself with the navigation equipment on most vessels. Understanding these regulations and investing in additional equipment can make a big difference in ensuring a safe voyage.

It is essential to understand the local laws and regulations regarding boating at night and what lighting you need for each vessel. Boat operators should also be aware of their speed limits, acceptable waterway passage areas, and any potentially hazardous areas they should avoid.

In addition to staying knowledgeable about local regulations, your navigation equipment should be up-to-date and functioning appropriately. Marine vessels typically come equipped with depth sounders and radar systems, but investing in additional accessories can further increase visibility during nighttime sailing. This equipment can include GPS chart plotters or portable AIS receivers, which can help navigate safer routes and alert boat operators of nearby vessels.

Necessary Lights for Boating at Night

Depending on illuminated waters after dark, boat light illumination is necessary for all recreational vessels. Boats must display three main types of lights, including bow, stern, and riding lights.

The bow light indicates to other boats where your vessel’s direction is facing, appearing as a green light on the starboard side and red on the port side when looking forward from the rear. It is important to note that this light should only be visible from directly ahead or nearly directly ahead of the vessel itself. It must have a wide enough angle range for optimal visibility while ensuring it is not too bright or blinding for other boats passing by.

The stern light works similarly to a bow light, except it shines from the back end of a vessel, making it easier for oncoming boats to identify your direction. Per maritime law, this light should also appear white but visible from behind only, ensuring no unnecessary glare toward other boats or obstructions ahead.

Riding lights, or masthead lights, provide additional visibility for your vessel. These lights indicate the vessel’s length according to measurements determined by maritime law enforcement officers. This type of light usually appears as white but occasionally has a blue tint depending on individual regulation standards in your area.

Understanding the Importance of Visibility

When selecting boat lights, it’s crucial to consider their wattage output or bulb type to ensure optimal visibility in dark environments.

Colored boat lights are often found on vessels and can come in white, blue, or red colors, each serving a specific purpose based on the laws at sea. White lights generally have a stronger output compared to other colors. Blue lights are more effective underwater, and red lights can mark specific areas within narrow channels, among other uses.

In addition to colored boat lights, reflective materials like tape can upgrade the common areas on ships, such as rails or posts. These materials help draw attention to the vessel’s proximity to other nearby ships and enhance safety.

Maintenance and Troubleshooting

Proper maintenance of boat light systems is crucial to keep operating costs low, especially when dealing with high-wattage fixtures commonly found in the marine environment. Regularly maintaining these systems throughout their lifespan is essential.

One critical maintenance aspect is storing boat lights properly during off-season storage periods. It is crucial to ensure that each unit remains dry. This storage is necessary to preserve their longevity and ensure their functionality when powered back on. Moisture buildup can lead to short circuits, malfunctions, and damage to the light’s components.

You should follow basic troubleshooting methods as part of routine maintenance. This maintenance includes cleaning off any corrosion and regularly checking bulb connections. These steps should become a natural course for anyone embarking on nighttime sailings or exploring uncharted territories.

Proper illumination is crucial for safe and legal boating at night. All boats need to have adequate lighting regardless of their size and capabilities. Following maritime laws and regulations related to navigational requirements and using the correct boat light format enhances safety for everyone on maritime travels. The mastery of navigation skills and adherence to these standards will continue to uphold the honor and legacy of future generations.

Boat Navigation Lights Rules: Illustrated Beginners Guide

When navigating at night, the lights on other boats are your first clue about the moving dangers around you. And your navigation lights are your first line of safety in avoiding collisions in the dark, and they tell others vessels what you are and what you are doing. The rules sound complex, but with a little understanding you can get the basics for any situation.

So what are the basic navigation light rules? For most small vessels, motoring requires red and green (port and starboard) lights, and a white light visible in all directions around the boat. This is almost always a stern light and a masthead light on sailboats. Boats under sail require port and starboard lights, and a white stern light. Sailboats below sixty-five feet may show a tricolor light at the masthead instead of side and stern lights when sailing.

That's it, in a nutshell. There's a little more to it, as the rules change with different sizes and there are some specifics about angles of display for the colors. Identifying other ships at sea requires more study, but the basics are the same. And it's not much trouble to make sure you've always got the proper lights on your vessel.

Infographic for Marine Navigation Lights Rules based on sailboat size

Masthead Light - a white light placed centerline on the boat showing an arc of 225 degrees with 112.5 degrees either side of the front of the vessel.
Sidelights - A red light on the port side and a green light on the starboard. They must show an arc of 112.5 degrees from centerline of the bow.
Stern light - A white light on the stern of the boat showing an unbroken arc of 135 degrees from centerline of the vessel.
All-round light - A light showing in an unbroken arc of 360 degrees.

The good news is you need not measure these angles. Any properly installed USCG or COLREGS approved light which will cover the correct arcs. If you have to replace the original light from your boat, make sure it's with an approved replacement.

Lights When Sailing

The specific rules for a sailboat under sail are in COLREGS Rule 25 and vary slightly with the size of the boat. A sailboat powering is considered a power boat and falls under in Rule 23.

Under 23 feet (7 meters) - side lights and a stern light, possible. If these lights can not be displayed a light must be kept at hand to help avoid a collision. This can be a bright flashlight.
Over 23 feet - Side lights visible to one nautical mile and stern light visible for two.
Vessels under 65 feet may combine both sidelights into a single lantern on the bow.
May show a tricolor light on the masthead instead of sidelights and a stern light. It's one or the other though, do not show these lights at the same time .
Masthead light must be visible for three nautical miles, all other lights must have a two nautical mile visibility.
Side lights must be separated.
May not show a masthead tricolor light.
Masthead light must have five nautical mile visibility, all other lights must be visible for two nautical miles.
Optional masthead lights - any vessel under sail may display a red light over a green light at the masthead with sidelights and stern light. The red over green may NOT be displayed with a masthead tricolor light. It's one set or the other.

Lights When Motoring

For all navigational purposes a sailboat under power is considered a power boat. This includes motor sailing - if the engine is on and providing propulsion you are on a power boat, even if the sails are up . This applies to navigation lighting, sound signals in fog and limited visibility, and rights of way.

Sailboats under 50 meters under power need to show:

A masthead light
Stern light

A power-driven vessel under 23 feet (7 meters) that does not exceed seven knots of speed may display an all around white light, though sidelights should be used if available.

The USCG has published its own "Rules of the Road" that are based on the COLREGS. In addition, it has rules for the "Inland Waterways" for rivers, inland lakes and the Great Lakes.

The good news is this has no impact on what you have to do with your own boat.

They mostly relate to lighting changes on towed vessels like barges and tugs. For example, a vessel towing or pushing another vessel in the ocean under COLREGS shows two masthead lights, sidelights and a stern light, whereas in Inland Waterways the towing or pushing vessel displays two yellow towing lights instead of a white stern light.

If you sail on lakes, rivers or the Great Lakes where towed commercial traffic is common you should learn the inland lights, but coastal or ocean sailors will never see these.

When you anchor outside a designated mooring field, you should display an all around white light at the masthead or as high in the boat as practical.

If your boat is large and has a very tall mast, you may wish to display another light closer to the waterline. Boats approaching in the dark may not see a light on a mast sixty or seventy feet in the air when they are close to your boat.

We use a simple garden path light on our stern when we anchor, left in a rod holder or flag socket. It comes on automatically at dusk and is a cheap and easy way to be more visible. There is no specific rule stating you can not display more lights than required, or the nature of any lights beyond the required all around light.

The COLREGS also specify that a round black "daymark" should be displayed in the rigging of any vessel at anchor. Very few small vessels observe this, however it is the correct display for a vessel in an anchorage.

If you tie to a mooring in a marked mooring area you are not required to display anchor lights, but there is no harm in doing so.

The other important reason to know your lights is to figure out what's going on around you at night. The water may be ablaze with white, red, green and other lights at night and they are your first key to avoiding collisions and problems.

All combinations of lights for fishing boats, commercial vessels, and so on are outside this post‘s scope. The odds are small you will encounter a submarine, seaplane or hovercraft at night, but there are regulations regarding specific lighting for each of those vessels!

There are a few fundamentals to help you figure out what that is you see on the horizon, which way it is going, and whether it is a danger to you.

Port Wine is Red

The fundamental rule is that red sidelights will ALWAYS be on the port side of a vessel, and green lights will always be on starboard. However, some vessels can use all around red and green lights for other purposes, though those will be higher than sidelights.

The light‘s on a ship is not important, some large tankers and freighters will have their sidelights far aft and put them on the superstructure for better visibility. It is not safe to assume that sidelights you can see are on the bow of large vessels .

When you can see the color, you know which way the bow is pointing. If it's red, it's pointing more or less to the left and will travel in that direction. A green light shows it is heading more or less to your right.

If you can see the red and green lights at the same time, you are looking directly at the bow of the vessel. When you are far away, this isn‘t as alarming as if you are close crossing. Seeing red and green lights together on a vessel is something you never want to see for long.

Be aware of red and green lights used in combination with other red, green and white lights. These may not be running lights and could have other significance.

Tankers, Freighters and Large Ships

Tankers, freighters and large ships will have side lights, a stern light and a masthead light. In addition, on vessels over 50 meters there will be a second masthead light further aft and higher than the forward light. The masthead light positions are a better tipoff to the bow direction and how far from the bow the sidelights might be. Remember - on a large vessel the sidelights may not be at the bow or even close to it.

USCG Inland Rules allow for a second all-around white light on large vessels on the Great Lakes instead of a second masthead light.

Fishing Boats

Fishing boats engaged in fishing will have more complex light displays. When they aren't fishing, they will show lights like any power vessel, but Rule 26 spells out light combinations that vary by the fishing activity being done. In general:

Boats which are Trawling but not making headway will display a green all-around light over a white all-around light , and a masthead light aft of these lights. Boats making headway while trawling will show these lights, plus sidelights and a stern light.
A vessel fishing other than trawling will show a red all-around light over a white all-around light . When making way they will also show sidelights and a stern light.
If a vessel has gear more than 150 meters away from the boat, it will show a second all around light in the direction of the gear. The best rule is to give fishing boats as wide a berth as you can at night. They're easy to pick out if you check the top light configurations but their course may be difficult to predict.

Towing and Pushing

Towed vessels can be the most dangerous to cross, but they have the most lights to tell you what is happening. Refer to COLREGS or the USCG Rules of the Road Rule 24 for all combinations You can pick a tow/push vessel out with the following lights:

Two or three masthead lights in a vertical line. Three masthead lights shows a tow over 200 meters. Additional masthead lights may show for larger tow vessels.
A towing light (yellow light with the same characteristics as a stern light) directly above the stern light.
The will also have side lights and a stern light.
The towed vessel will show sidelights and a stern light. Lighting may vary under USCG inland rules, where towing lights may replace stern lights. Learn these differences if this is your regular cruising ground. If you think there is a tow ahead of you, always go well behind the aft most set of lights. Never go between a tow and avoid crossing ahead if possible as it may restrict their maneuverability.

Special Situations

There are several rare situations you may encounter. As a general rule, if there are a lot of lights and you don't understand them look for the sidelights on a moving vessel. If you can find them and figure out the direction it is moving, it makes the vessel easier to avoid. Stay well clear of lights you do not understand if you can avoid them without risk.

Most of these signals are used by larger, commercial vessels and you will not need them.

They use these light combinations with other light combinations. For example a towing vessel may also be restricted in maneuverability, and a vessel constrained by draft will show running lights if moving.

Not Under Command - two all around red lights in a single line
Restricted in Ability to Maneuver - red, white then red in a single line
Constrained by draft - three all around red lights

Navigation Lights for Sailboats (And How To Read Them)

Last Updated by

Capt Chris German

June 15, 2022

Navigation lights on a sailboat can be confusing. If you understand the reason behind why they are the way they are however, they can make a lot more sense.

At their heart, sailboats are really just a power boat and as such must adhere to all power boat rules such as navigation lights. Other times however, a sailboat is classified in a special category. They have a set of additional lights they CAN show as an option, but are not always required to do so.

That’s about as clear as mud if you ask me and I contend that that is where the confusion about lighting a sailboat begins.

Just because you can show a light to identify yourself in times of low visibility, does not mean you have to and then we add in a little sibling rivalry between power and sail and things get downright adversarial when it comes to navigation and the night.

Table of contents

The USCG says You’re a Power Boat Whether You Like It or Not

Much to the consternation of many a sailor who has earned a commercial license to drive their sailboat, when you received your credential from the USCG it says you are a master of steam and power across the top with no mention of wind as a source of propulsion.

It is not until you read the back pages of your little red book that feels like a passport and looks like a US Sailing credential, that you will see the term “sail auxiliary”. That is because most of the time the U.S. Coast Guard knows that you are primarily reliant on your mechanical power to propel your vessel.

It's a sad thing, but the days of commercially viable sail boats are done and all but the most select few even have sails let alone use them as their primary power source. All sail boats by law are powerboats, but not all powerboats are sailboats.

Navigation Lights for a Power Boat

As a power boat, you are required to show certain lights and have been required to do so before power was even invented.

In the days of man powered vessels like the viking ships who relied on oars while in close quarters to power their vessels, they needed to show other boats, friend or foe, where they were by showing lanterns in the dark to identify themselves. As you know, it is a time honored rule among all the nations of the world both past and present, that you must avoid a collision at all costs while at sea and even the viking knew that you should not run into things.

By lighting the front and back of your boat, you could warn other boats of your presence as well as identify which way you were heading. As such there is a very specific rule in the Code of Federal Regulations Number 46 (CFR46 by common name) that spells out with detail how many, the color, the luminosity or brightness, the angle of visibility and the location of all of the lights required for navigation on every single boat, seaplane, submarine and other nondescript vessel conceived by man to date that they must show while underway in reduced visibility.

And there is no flexibility in the rules.

As such a power boat, and by extension all sailboats, MUST, without question show one green light on the starboard bow and one red light on the port bow and one all around white light or lights while operating in reduced visibility. These lights should shine at all 360 degrees of visibility with the bow lights shining at an angle of dead ahead to 22.5 degrees abaft the beam and the stern lights shining 225 degrees dead aft. A forward facing masthead light that is white in color shall shine forward to comply with the directive that all vessels must carry an all around white light. For more read here .

As you can see, there isn’t much wiggle room when it comes to lights that must be shown.

Sailboats get a little flexibility with lights

Sailboats however, are a little different when they are in fact sailboats, which is only when you are entirely reliant on the wind for power and in no way reliant on any mechanical or manual means of propulsion. And for good reason.

Back in the day when men were men and sailboats were wooden, fire was a major concern. Sails were coated with wax and other flammable substances and the wood on boats was saturated with oils and grease. Even the ropes were plant materials saturated with oils to keep them pliable and strong.

Add those highly flammable substances to a parching environment like the sea and you had what was essentially a giant floating tinderbox.

Then tell that giant floating tinderbox that they need to identify themselves to the world at large at night using oil lamps with flames because batteries and lights were not invented yet. It didn't take very long or very many ships burning to the water line for the Governments to say to the sailboats, you get to do things a little different.

As such, sailboats are given special dispensation when it comes to lights aloft. They don't have to show an all around white light in their rigging because no one wanted to set their rig on fire with oil lamps 60 feet up in their rig.

However, when a sailboat takes their sails down such as when they are powered or at anchor, they must resume the display of an all around white light or lights aloft. That became a real challenge with aluminum masts and the disappearance of rat lines on the shrouds because there was no easy way to climb the rig and check the bulbs up the mast on a regular basis.

Red over Green Sailing Machine

I have no idea where the history of this particular light comes from, but if you ever take a deck exam with the USCG, you better remember this mnemonic. An all around red light over an all around green may be displayed on a vessel during times of reduced visibility to indicate that a vessel is operating under sail power alone.

I won’t even speculate on how or why they came up with this particular light configuration, but if you want to use these lights as a sailing vessel, you can do so, but that means that you will need three all round lights at the top of your mast, an all around white, an all around red and an all around green, just in that order.

The red over green is to be displayed in addition to the running lights or the red and green bow lights with the 225 degree stern light. As always, when the motor comes on, so does the steaming light or the forward facing white light that is also usually about ¾ of the way up on your mast to complete the requirement of an all around white light that indicates a power vessel.

What is a “steaming light” and why are you mentioning it now?

Most sailboat electrical panels will have a switch that is labelled “steaming light” and it will only come on when your anchor light is off. This is probably the most confusing part of sailboat navigation lights so if you are confused about this, you're in good company as most people are.

A “steaming” light is named thusly, going back to the days of steam powered sailboats where when they fired up their boilers and doused the sails, they became a power boat once again. There aren’t too many steam powered boats, let alone steam powered sailboats, but the name stuck and it is a vestige of a bygone era.

Either way, when you fire up your motor, you turn on your “steaming light” and that locks out the all around white light which is used for anchoring to minimize the number of switches on your panel and reduce the number of wires in your mast. The fewer wires, the less chance of something not working or becoming disconnected.

The steaming light and the anchor light both go up the mast, but you can’t use an all around white light while using the 225 degree stern light at the deck level because to other boaters you would look like you have two white lights from the stern and that would be confusing.

The anchor light is used exclusively for anchoring while the steaming light is used to indicate you are a power vessel while underway.

As to why I am mentioning it now in the article, is because this would have blown your mind if I started with this subject cause it can be really confusing stuff.

Aspect Recognition with Lights

Remember when I said earlier that lights can help you tell others which way you are heading as well as tell you which way other boats are heading? That is called the aspect of the vessel and the USCG tests you on this for your deck exam as well.

Knowing that the bow lights go 22.5 degrees abaft the beam on both sides or 112.5 degrees on each side, and the stern light faces 225 degrees aft for a total of 360 degrees of visibility, you can tell a lot about where a boat is heading and who has the right of way.

One thing that's easy to remember is red means stop and if you see a vessel's red light, it means stop as you are the give way vessel and approaching the other vessel from his port side. Conversely it works with green as well as that means you are approaching from the other vessel's starboard side and you are the standon vessel.

If you see a red and green light equally low on the horizon, that means your heading dead on into another vessel's path and conversely if all you see is a white light low on the horizon, it means you are overtaking another vessel power or sail, we don’t care because it is an overtaking situation. However, any time you do see a white light aloft in addition to the red and green bow lights, you know you are encountering a power boat.

Then there are angular approaches as well, where you see white and red or white and green light low on the horizon. You know in that case you are seeing a portion of the bow lights and stern lights from the side approaches of a vessel. Based on which direction those lights are heading, you can deduce which way that boat is going in relation to your boat.

So put it all together and you see a green light and a white light low on the horizon with a red over green light aloft, you know that you are approaching a sailboat that is traveling to your port and that might make you the standon vessel. That is of course, if we didn’t concern ourselves with windward and leeward and port tacks and starboard tacks, but that is a discussion for another article. So stay tuned when we talk about sailing rules and the right of way. But for now, do good, have fun and sail far.

You can't do it without the correct lights

While on land, lights are primarily there to help us see, at sea it's the other way around. All boats must be properly lit for other vessels to see. And, a boat doesn't work like a car either, where we shine our headlights on the road ahead to see what's in front of us. At sea we rely on navigation, nautical charts, lighthouses and the captain's knowledge.

Basic boat lights include running lights, steaming lights and anchor lights. There are clearly defined and standardized rules for lighting a ship under sail at night . So the question of how to light a yacht at night has a very simple answer. Running lights, or side lights, show other vessels where your port and starboard sides are, with red indicating port and green starboard, and you must also have a white stern light on.

Lighting the yacht at night is very important because, unlike during the day, the helmsman cannot judge the distance and direction of other boats by sight. Running lights make the position and direction of the surrounding vessels visible, as well as their approximate distance, and helps to avoid possible collisions. Radar is also highly practical in this respect, as it shows the size and distance of the vessel.

However, when sailing there can be situations where the sails need to be lowered, and with that, the lighting also needs to be changed. If travelling under motor power , a steaming light (masthead light) must be turned on , which shines at the same angle as the side lights. When a sailboat is not under sail, it has to abide by the rules set out for power boats by COLREG (The International Rules for Preventing Collisions at Sea).

Lighting regulations when at anchor are again different. When at anchor at sea , only the anchor light should be on . According to the regulations this could be either a 360-degree white light atop the mast, or a light suspended from the boom, above the foredeck or on a furled genoa. If the boat is moored in port, the light is not normally used.

Navigation, GPS and maps

Nowadays, GPS and navigation aids integrated into the boat or that work as mobile apps are commonly used to determine the position of the boat. Modern technology is very accurate and reliable, but it is still worth understanding, reading and checking your position on paper nautical charts . After all, almost any skipper will tell you that their GPS or navigation system has at some point told them they were on land, even when tens or hundreds of metres from shore.

Thanks to nautical charts, you will not only know of possible danger spots, but also lighthouses , enabling you to easily and accurately determine your position with the help of a compass. Each lighthouse is different, being lit and flashing in a unique way. A nautical chart will tell you how to identify a lighthouse by the number of flashes, their frequency and the colour of the light. To determine your exact position, you’ll then need two lighthouses in sight that serve as reference points for each other.

YACHTING.COM TIP: Lighthouses are not only practical, but they are often buildings with impressive architecture that are well worth stopping off at. Take a look at 15 lighthouses you must visit .

Safety is paramount when sailing at night

Even during the day, there are clear rules regarding the movement of the crew on board. Basically, the crew should not stand unless they are engaged in manoeuvres. In all other cases, they should be sitting on benches, at the side of the boat when heeling, or in the cabin. Apart from the fact that a standing crew member could obstruct the helmsman's view, it also poses a greater risk of falling overboard . If you're interested in getting to know this subject in more detail, check out our article Sailing Etiquette A to Z .

At night, the rules are even stricter to ensure the crew remain as safe as possible and avoid damaging the yacht. If a crew member is on deck at night while sailing, they should wear a lifejacket and ideally be attached to the boat with a lifebelt or harness.

Except for really experienced seafarers, the rule of thumb is that there should be at least two people on board when sailing at night. And the captain should schedule shifts so that there are always two rested crew members on board. After all, you need to be doubly vigilant when sailing at night, and staying awake all night is certainly not conducive to alertness — especially when manoeuvring or entering port. For the same reasons alcohol is prohibited when night sailing. While during the day, crew members other than the helmsman can toast Neptune or have one glass of wine or beer, drinking alcohol is not permitted during a voyage at night. By all means celebrate a successful journey upon arrival in port at a local tavern, but it definitely pays to keep a clear head at sea.

Specifics of night sailing and boat handling

Steering and controlling the boat is not particularly different during the day and at night. There are just a few nuances to make sailing that bit smoother. If you're on a vessel you know well, that’s one thing, but if you're on a charter boat , it's worth marking the sheets and other lines so that you know your way around in the dark.

Sailing at night, it is also important to assess the weather conditions well. What you would normally do during the day can be significantly more challenging at night and requires a more careful assessment of weather conditions and weather patterns. It is always better to choose smaller sails and if you have even the slightest doubt about anything, postpone the trip.

When entering a harbour or sailing close to shore, be doubly cautious. There are several risk factors. During the day, the surrounding boats, the rocks and the potential hazards on the surface and below are visible. At night you have to rely on navigation, charts and lighting. When entering the harbour, charts and GPS can provide you many clues but lights can cause issues. For example, you might get dazzled by the light from the shore, the anchor lights of other boats are easily confused with the lights on land, and, last but not least, you may encounter poorly lit fishing boats. However, if you keep in mind all of these potential risks, you will arrive safely in the harbour.

The magic of night sailing

When compared to sailing during the day, night sailing places more demands on the captain's experience and knowledge of sailing regulations. But it is also a truly romantic experience. Millions of stars glistening in the night sky and the waves sparkling in the moonlight. If you're lucky, sailing out of the mist from land on a clear night with a near full moon, it will seem almost like daylight.

If you're serious about sailing and steering your boat, there are other benefits to night sailing. Navigating at night sharpens the senses and enhances the sailing experience as well as your experience of the sea itself. It truly gives a whole new meaning to sailing. But if all you want is to just enjoy yourself, night sailing is one of the most romantic experiences you can have. Check out our article on how to enjoy romance on board a yacht charter .

Navigation Lights

You are required to display the appropriate lights at night or during times of reduced visibility.

Navigation lights are used to prevent collisions at night or in times of reduced visibility, and are an essential tool in keeping you and your vessel safe. Nav lights allow you to see other nearby vessels, and allow other vessels to see you.

Nav lights also provide information about the size, activity, and direction of travel. By understanding the characteristics of Nav lights, you can determine an appropriate course of action as you approach another vessel.

On any vessel, navigation lights have a specific color, (white, red, green, yellow, blue), arc of illumination, range of visibility, and location, as required by law and regulations. For the purposes of this course, we will concentrate on pleasure boats under 65 feet in length. Knowledge of navigation lights is important to a small-boat skipper for separate, but important, reasons.

You are legally responsible for displaying lights of the proper color, intensity, location and visibility on your boat.
Knowing the type and heading of another boat.

Legal Requirements

Vessels are required to show the proper navigation lights from sunset to sunrise in all weather conditions, good and bad. During these times, no other lights that could be mistaken for lights specified in the Rules of the Road can be displayed, nor any lights that impair the visibility or distinctive character of navigation lights, or interfere with the keeping of a proper lookout. The Rules also state that navigation lights must be shown in conditions of reduced visibility, and may be shown at other times considered necessary.

It's Your Responsibility

It is the responsibility of the owner/operator of a vessel that she show the proper navigation lights for her size and the waters in which she is operating. It is not the responsibility of the manufacturer, importer, or selling dealer. Many boats are delivered with lights that do not meet legal requirements with respect to technical characteristics or placement on the vessel. Remember also, that the angles of visibility must be met when the boat is underway-if your boat rides at a significant bow-up angle, take that into consideration when installing and/or checking your lights.

Navigation Lights for Powerboats

Power driven vessels underway shall exhibit a masthead light forward, sidelights and a stern light. Vessels less than 12 meters in length may exhibit an all around white light and side lights. Power driven boats on the Great Lakes may carry an all around white light in stead of a second masthead light and stern light combination.

Sidelights - Colored lights - red on port and green on starboard - showing an unbroken arc of the horizon of 112.5 degrees, from dead ahead to 22.5 degrees abaft the beam on each side.

Combination lights - Sidelights may be combined in a single fixture carried at the centerline of the vessel.

Stern light - A white light showing over an unbroken arc of the horizon of 135 degrees, centered on dead astern.

Navigation Lights for Sailing

A sailing vessel of less than 7 meters in length shall, if practicable, exhibit regular navigation lights, but if not practical, she shall have ready at hand an electric torch or lantern showing a white light which shall be exhibited in sufficient time to prevent collision.

Diving Lights

Another light display that you may see in resort areas, or waters that have wrecks or reefs, is the night diving configuration. This has three vertical masthead lights, that have a red-white-red sequence. You must maintain a good distance from these vessels, and you should also be aware that there may be divers near you.

Interpreting what you see

It's great that you're learning the basics of lights - what is required and when they're required. But, this in only the beginning. You must also learn how to interpret the navigation lights that you see when you are underway at night- and for your safety-learn it well.

For instance, if you see a vessel approaching that shows a light pattern such as the ones to the right, you immediately know that you are in a crossing situation, and that you must yield to the other vessel - that's why it is red.

Seeing a green light over a white light indicates a fishing vessel actively trawling. You not only need to avoid the vessel, but you also need to remember that it could potentially have a very large net deployed that you will also need to avoid.

And there are numerous other lights and combinations of lights that you must be able to instantly recognize - the lights for a sailboat that is privileged over a motorboat, the special lights of various fishing vessels, a dredge or a vessel not under command. Study the requirements for navigation from the viewpoint of a "looker" as well as a boat owner.

Navigation: Boat Lights at Night

Boating at night is an experience like no other as navigating waters becomes enchantingly beautiful and potentially challenging. Certain essential safety rules need to be followed, and boat lights at night tops that list. These play an invaluable role and are necessary for maintaining visibility, preventing collisions, and complying with legal requirements.

This comprehensive guide explores various facets of boat lighting: from understanding their importance to knowing different types of lights and more; Additionally, we decipher the regulations, discuss correct usage, offer safety tips, and much more.

Key Takeaways

Appropriate boat lights are not just necessary for legal reasons but also play a crucial role in ensuring the safety of your boat and those around you during nighttime or low-light conditions.
Understanding the different types of boat lights (masthead light, stern lights, sidelights, all-around white light) and their placement based on your boat's length is critical.
Understanding how navigation lights work is essential - red stands for the port side and green for the starboard side. This knowledge will aid in recognizing the direction of other boats based on their lights.
Various specialized lights serve specific purposes like docking lights for assisting dock arrival, spotlights for identifying landmarks or buoys, etc. Extra caution should be used to ensure these do not disrupt other boaters' vision.
The law mandates the display of appropriate lights from sunset to sunrise; failure to adhere to this rule can result in heavy penalties.
The International Regulations for Preventing Collisions at Sea (COLREGs) specify rules relating to navigation lights. Familiarity with key COLREGs rules ensures safe and lawful operation of vessels.
Safety precautions like carrying spare fuses and bulbs onboard, dimming electronic devices, installing red lights within the cabin, using reflective tape, slowing down, wearing life jackets, and using onboard electronics go a long way in planning for unexpected eventualities while boating at night.

Understanding the Importance of Boat Lights at Night and in Reduced Visibility

Good navigational lighting isn’t just another feature; it’s a critical safety component for use after sunset or in low-light conditions. Being out in the open water devoid of any light can be disorienting, and navigation lights assist you in identifying your location and your path.

Lights During Reduced Visibility

Nighttime isn’t the only scenario where the vision becomes poor; even during foggy weather, rain, or heavy cloud cover, you can find yourself in situations of reduced visibility. Under these circumstances, lights can be a beacon. They alert other boaters of your presence, helping you to be seen, even in the murkiest conditions.

Role of Lights in Preventing Collisions

A clear night can quickly turn dangerous without proper lights. Aside from keeping you on the right track, they also play the essential role of signaling to other vessels your location and the direction in which you’re moving. This simple communication can avoid dangerous close encounters and help prevent collisions, a risk that increases with every unlit boat on the water.

Requirement of Displaying the Appropriate Lights for Safety and Legal Reasons

Legally, you are required to display appropriate lights from sunset to sunrise and in periods of low visibility . Failing to do so can result in heavy fines and penalties. Even more than that, displaying the right lights is a universal sign of responsibility and respect for other boaters’ safety. Remember, an illuminated boat is a visible boat, and a visible boat is a safe boat.

Types and Placement of Boat Lights

There are four main types of lights to display:

The masthead light, also known as the steaming light, is a white light positioned in the middle of the front part of the boat and higher than the side lights. It shines light from the front to a little bit behind the sides of the craft. When under power, it indicates the direction of travel.
Sidelights, which display green on the starboard (right) side and red on the port (left) side of the boat, illuminate the areas not covered by the masthead light. These lights are visible to other boaters from the front and side of the vessel.
The stern light, also white, shines backward, allowing other vessels to see your vessel from behind and gauge its direction and position. It is mounted high enough to be visible over the transom or other equipment but lower than the Masthead Light.
Often found on smaller craft, the all-around white light(360 degrees) is visible from all directions. It can be used in place of the masthead and stern lights and should be installed at the vessel’s highest point.

Correct Placement of Lights on Boats of Different Lengths

The placement of the lights depends on the length and type of your boat. Boats less than 12 meters in length may exhibit an all-around light and sidelights. In contrast, larger vessels are required to have separate masthead, stern lights, and sidelights.

Difference Between Sailboat and Powered Boat Light Placements

The placement and visibility of lights vary between sailboats and powered boats.

A motorboat needs a masthead light that can be seen from two miles away, sidelights that are visible for one mile, and a stern light. However, a sailing boat only requires sidelights and a stern light unless it’s being powered by an engine, in which case it also needs a masthead light.

Navigation Lights and Their Correct Usage for Boating at Night

As mentioned above, the red and green lights are key parts of marine navigation, mirroring the colors of traffic lights. These lights should be visible for an arc of 112.5 degrees from the front of the boat. Knowing this helps you determine which way other boats are heading.

The visibility range for your lights depends on the type of boat and what it’s doing at the time. Typical coverage for navigation lights can vary from 112.5 degrees (for sidelights) to 360 degrees (for an all-round light), providing visibility in all directions.

The lights also tell you about a boat’s direction of travel. For instance, if you see red and green lights ahead, the boat is approaching. On the other hand, if you only see a white light, it could mean the vessel is moving away from you.

Special Light Requirements When the Boat is at Anchor or Towing Another Vessel

An anchored boat must show an all-round white light, ensuring it can be seen from all directions. This light should be installed at the highest point for the best visibility.

When a boat tows another vessel or object, towing lights signal this activity. These lights consist of a yellow light placed close to the stern light.

Visibility Ranges for Different Boat Sizes

International regulations specify different visibility ranges based on boat length:

Boats less than 12 meters in length (39.4 feet): Masthead/Steaming Lights must be visible for at least 2 nautical miles. Sidelights and Stern Lights should be visible to other boats for at least 1 nautical mile.
Boats between 12 and 20 meters (39.4 to 65.6 feet): Masthead/Steaming Lights should be visible for at least 3 nautical miles. Sidelights should be visible for at least 2 nautical miles, and Stern Lights for at least 2 nautical miles.
Boats between 20 and 50 meters (65.6 to 164 feet): Masthead/Steaming Lights should be visible for at least 5 nautical miles. Sidelights should be visible for at least 2 nautical miles, and Stern Lights for at least 2 nautical miles.

Judicious Use of Specialized Boat Lights for Specific Situations

The danger of using bright, forward-facing lights while underway.

Imagine driving along a dark country road when a car from the opposite direction suddenly fails to dip its headlights. Quite a dazzling experience, right? Similarly, illuminating ultra-bright, forward-facing lights (like searchlights or docking lights) while on the move can disrupt other boaters’ night vision, making it harder for them to navigate safely. So, unless you’re docking or need to illuminate a short-range area, it’s best not to use them.

Usage of Docking Lights

Contrary to some beliefs, docking lights are not meant for long-range viewing or communication with other vessels. As the name hints, their primary purpose is to assist you while docking at night. These high-intensity lights help illuminate the area directly in front of your boat, allowing you to see your dock or slip.

Benefits and Disadvantages of Spotlights

Spotlights can be handy when searching for buoys , identifying landmarks, or person overboard situations. However, they must be used sparingly and thoughtfully on the water to avoid disorienting other boaters. A good rule is to use them intermittently – only when necessary – and never shine them in the direction of another boat.

Avoiding Confusion with Regular Navigation Lights

Comprehensive lighting on your boat is a good idea, but it must never interfere with or be confused with your navigation lights. Any decorative or additional lighting should not mask, obstruct, or be mistaken for your boat’s red, green, or white navigation lights. After all, these lights are a crucial part of the language of the sea, and it’s vital other boaters can read them correctly.

Extra Lighting for Fishing at Night

Extra lighting serves two main functions when you’re fishing at night. Firstly, it illuminates your immediate surroundings, making casting, landing, and unhooking fish convenient. It also ensures the safety of your movements in and around the boat. Secondly, the right light may even attract fish!

Precautions to Take Not to Impair the Night Vision of Other Boaters

As with driving cars at night, you must follow certain etiquette and safety precautions with your fishing lights. Refrain from pointing your highly focused, bright lights toward another boat, and if using underwater lights to attract fish, ensure they are not mistaken for navigation lights.

Required Lights when Fishing at Certain Distances from Shore

Boating lights: rules and regulations, understanding key colregs rules.

Navigating the open seas requires adherence to international rules known as the International Regulations for Preventing Collisions at Sea (COLREGs). These rules include specific guidelines about using navigation lights on different types of vessels and in various conditions. Here’s a brief overview of some of these essential rules:

The International Regulations for Preventing Collisions at Sea ( COLREGs ) contain essential navigation light rules on different types of vessels and in various conditions. Here’s a brief overview of some of these:

Rule 23: Power-driven vessels underway: This rule outlines the navigation light requirements for boats operating under power.
Rule 25: Sailing vessels underway and vessels under oars: This rule specifies the navigation light standards for sailing boats and vessels propelled by oars.
Rule 20 (Application): This rule states that the navigation light rules apply to all vessels on the high seas and in waters connected to the high seas navigable by seagoing vessels. It also specifies that the rules apply from sunset to sunrise and during reduced visibility, such as fog, rain, or haze.
Rule 21 (Definitions): Rule 21 provides clear definitions of various terms related to navigation lights, such as masthead lights, sidelights, stern lights, towing lights, all-round lights, and flashing lights. Understanding these definitions helps ensure proper usage and compliance with the regulations.
Rule 22 (Visibility of Lights): This rule specifies the minimum visibility range for different navigation lights based on the vessel size, which we discussed in the “Visibility and Range of Navigation Lights at Night” section. Adhering to these visibility requirements is crucial for safe navigation and avoiding collisions.
Rule 24 (Towing and Pushing): Rule 24 outlines the navigation light requirements for vessels engaged in towing or pushing operations. Towing vessels must display a masthead light, sidelights, and a towing light, while the towed vessel must display sidelights and a stern light. Vessels pushing ahead or towing alongside should exhibit sidelights, a stern light, and a special flashing light.

Safety Precautions and Tips for Night Boating

Here are some safety measures and tips to consider when you’re out on the water at night:

Carry spare fuses and bulbs on board.
Install red lights: Equip your helm, cabin, and other workspaces with red lighting.
Dim the brightness of electronic devices, such as GPS units or chartplotters.
Always have a waterproof flashlight or headtorch with a red light mode available for emergencies or when you need to perform tasks that require focused light.
Apply reflective tape on critical areas of your boat, such as rails, life jackets, and safety equipment.
Install deck and courtesy lights for low-level illumination around the cockpit and deck walkways.
Slow down to give yourself more time to react to environmental obstacles or changes.
Maintain a proper lookout to watch for other vessels, obstacles, or navigational markers.
Make the most of your onboard electronics, such as radar and GPS/chartplotters, to improve your situational awareness at night.
Wear a life jacket or PFD , especially in low-light conditions when seeing someone who has fallen overboard may be harder.

Final Thoughts

Navigating at night or in reduced visibility can be a challenging yet rewarding experience when done properly. Central to this adventure is understanding and implementing appropriate navigational lights according to maritime rules and regulations, serving not only as an aid for safe travel but also as an indication of respect for fellow boaters. Remember, each type of light serves a particular purpose, whether the masthead light indicates the direction of travel or sidelights help you understand another vessel’s path.

Know that using bright forward-facing lights while on the go may impair other boaters’ vision, while docking lights & spotlights should be used minimally and thoughtfully. Similarly, if you’re fishing at night, ensure your lighting doesn’t confuse or inconvenience others. Finally, conforming to laws like displaying correct lights from sunset to sunrise and understanding key COLREGs rules are imperative for legal compliance.

Pair these safety measures with effective preparations such as carrying spare fuses and bulbs, slowing down your speed, keeping additional waterproof flashlights, and wearing life jackets to enhance your safety while night boating greatly.

The basic boat lights for night operation include a stern light (white), sidelights that indicate the port (red) and starboard (green), and masthead light (white). These lights allow other boats to see you in the waterway, enhancing safe navigation.

Boat lights for night operations are crucial for safety and are required by law. They help you see and be seen by other boats, preventing potential accidents.

It’s legally required to exhibit appropriate navigational lights only from sunset to sunrise or during periods of restricted visibility, such as foggy conditions, heavy rain, or cloud cover.

Failing to comply with relevant laws and regulations regarding marine lighting can result in hefty fines and penalties. Besides legal trouble, improper use increases collision risk endangering everyone aboard.

Both powered and sailing boats require a masthead light when under power propulsion. When using sails without engine assistance, sailing boats do not need a masthead light but must display sidelights and a stern light.

Yes, larger vessels generally require their navigation lights to be visible from greater distances. For example, for boats less than 12 meters long, the rules state that sidelights should be visible from at least one mile away and the masthead light from two miles away, but these distances increase for larger vessels.

Docking lights are not essential, but they help illuminate the area directly in front of your boat while docking at night. However, they should not be used when moving since they might dazzle other boaters and interfere with their navigation.

When your boat is anchored between sunset and sunrise, you must exhibit an all-around white light visible from every direction. This rule applies in low-visibility weather too.

The Night Navigation Techniques

Navigating at night presents unique challenges for sailors, but mastering the essential techniques and tools can ensure safe and thrilling nocturnal sailing adventures.

Sailing at night can be an exhilarating and rewarding experience, but it also presents unique challenges and requires a different set of skills than daytime sailing. In this article, we’ll explore the essential techniques for successful night navigation, ensuring that you and your family can safely and confidently embark on your nocturnal sailing adventures.

Understanding the importance of night sailing skills, preparing your boat for night sailing, night navigation tools and equipment, using the stars for navigation, understanding and identifying lights at night, night sailing safety tips.

Before we dive into the specific techniques and tools for night navigation, it’s essential to understand why these skills are so crucial for sailors. Night sailing can be a necessity for long passages, allowing you to cover more distance and make the most of favorable weather conditions. Additionally, sailing at night can provide a unique sense of freedom and connection to the natural world, as you glide through the water under a canopy of stars.

However, night sailing also presents unique challenges, such as reduced visibility, difficulty identifying landmarks and other vessels, and increased fatigue. By mastering the techniques and tools for night navigation, you’ll be better equipped to handle these challenges and ensure the safety of your family and your vessel.

Before setting sail at night, it’s essential to prepare your boat and ensure that all necessary equipment is in good working order. Here are some key steps to take before embarking on a night sailing adventure:

Check your navigation lights: Ensure that your boat’s navigation lights (red and green sidelights, white stern light, and white masthead light) are functioning correctly and are visible from the appropriate distances. These lights are crucial for signaling your position and course to other vessels.

Inspect your safety equipment: Double-check that all safety gear, such as lifejackets, harnesses, and tethers, is in good condition and easily accessible. It’s also a good idea to have a dedicated set of night-vision binoculars on board for increased visibility.

Prepare your cockpit: Organize your cockpit to minimize the need for movement and ensure that essential tools and equipment are within easy reach. Consider using red or amber lighting in the cockpit to preserve your night vision.

Plan your route: Before setting sail, plan your route and identify any potential hazards or navigational challenges. Familiarize yourself with the local tides, currents, and weather conditions, and ensure that you have up-to-date charts and navigational aids on board.

In addition to the standard navigational tools used during daytime sailing, there are several specialized tools and equipment that can greatly enhance your night navigation capabilities:

GPS/chartplotter: A GPS/chartplotter is an invaluable tool for night navigation, providing real-time information on your position, course, and speed. Many modern chartplotters also include AIS (Automatic Identification System) functionality, allowing you to track and identify nearby vessels.

Radar: Radar is an essential tool for night sailing, as it can detect other vessels, landmasses, and obstacles even in complete darkness. By regularly monitoring your radar screen, you can maintain situational awareness and avoid potential collisions.

Night-vision binoculars: Night-vision binoculars use infrared technology to amplify available light, allowing you to see objects and vessels in low-light conditions. These binoculars can be particularly useful for identifying navigational markers, buoys, and other vessels at night.

Red or amber lighting: As mentioned earlier, using red or amber lighting in your cockpit can help preserve your night vision, making it easier to see objects and vessels in the darkness. Many sailors also find that red or amber lighting reduces eye strain and fatigue during long night watches.

While modern navigational tools like GPS and radar have made celestial navigation less critical for sailors, the ability to navigate by the stars remains a valuable skill for night sailing. By learning the basic principles of celestial navigation, you can enhance your situational awareness and develop a deeper connection to the natural world.

Here are some key concepts and techniques for using the stars to navigate at night:

Learn the major constellations: Familiarize yourself with the major constellations visible in your sailing area, such as Ursa Major (the Big Dipper), Orion, and Cassiopeia. These constellations can serve as reference points for determining your position and course.

Identify the North Star (Polaris): The North Star is a crucial navigational aid, as it remains relatively fixed in the sky and indicates true north. By locating the North Star, you can determine your latitude and maintain a consistent course.

Use a sextant: A sextant is a traditional navigational instrument used to measure the angle between a celestial object (such as a star or the moon) and the horizon. By taking sextant readings and consulting nautical almanacs, you can determine your position with a high degree of accuracy.

One of the most challenging aspects of night sailing is interpreting the various lights and signals encountered on the water. By familiarizing yourself with the different types of lights and their meanings, you can more easily identify other vessels, navigational markers, and potential hazards.

Here are some key types of lights to be aware of during night sailing:

Navigation lights: As mentioned earlier, all vessels are required to display navigation lights (red and green sidelights, white stern light, and white masthead light) to signal their position and course. By observing the color and configuration of these lights, you can determine the direction and orientation of other vessels and avoid potential collisions.

Aids to navigation: Navigational aids, such as buoys and beacons, are often equipped with lights to make them visible at night. These lights can be red, green, white, or yellow and may be displayed in various patterns (flashing, occulting, or isophase) to indicate their purpose and location.

Morse code signals: Some navigational aids and vessels may use Morse code signals to communicate specific information, such as their identity or position. By learning the basic Morse code alphabet and common signal patterns, you can more easily interpret these signals and navigate safely at night.

Finally, here are some general safety tips to keep in mind when sailing at night:

Maintain a proper lookout: Always have at least one crew member on watch, scanning the horizon for other vessels, navigational aids, and potential hazards. Regularly check your radar and AIS to maintain situational awareness.

Use your senses: In addition to visual observations, use your hearing and sense of smell to detect potential hazards, such as nearby vessels or changes in weather conditions.

Communicate clearly: Ensure that all crew members are aware of the current navigational plan and any potential hazards. Use clear, concise language and standardized terminology to avoid confusion.

Stay well-rested: Fatigue can significantly impair your ability to navigate and make sound decisions. Establish a watch schedule that allows for adequate rest and recovery for all crew members.

Night sailing can be a thrilling and rewarding experience, but it requires a unique set of skills and techniques to ensure the safety of your family and your vessel. By mastering the art of night navigation, you’ll be better prepared to embrace the challenges and rewards of nocturnal sailing adventures. So, grab your charts, study the stars, and set sail under the moonlit sky – the world awaits!

Top tips for sailing at night

When most boats have moored up for the night clive loughlin ventures out into a different world.

There is something rather magical about sailing at night, and I love it.

In many ways very little changes – the chart plotter, depth sounder, log, AIS and radar still work just as they do in daytime, and yet somehow everything is different.

Although you can sail at night with your eyes glued to an electronic screen, it is much more fun (and safer) to supplement technology with traditional techniques, and I hope the following will help you brave the dark.

Not to be undertaken lightly

Probably the single most significant safety measure is to make sure that your eyes have adapted to night vision before you set off (see box).

Most saloon and cabin lights are far too bright to be left on at night, and yet it is important to be able to pop down below without stumbling around. I like to use a bicycle rear light, or other torch switched to red mode, and reflecting off the saloon coachroof to provide a dim bordello-like atmosphere.

Switch on compass and instrument backlights and dim chart plotter displays to their lowest setting. They may look too dim at first but they will soon seem brighter as your night vision kicks in.

Dressing for the occasion

It gets cold at night so you must wrap up warm, and a woolly hat and gloves are essential.

Over the years I have spent a fortune on ‘sailing’ gloves and been disappointed. I now use industrial gloves designed for people working in refrigerated warehouses. These give me the dexterity I need, and are warm and very low cost.

A man overboard is really really bad news in daylight, but in the dark it is a literal nightmare. So always wear a lifejacket and clip on.

The eyes have it

The sensitivity of our eyes increases the longer they are in the dark and it typically takes 30-45 minutes for maximum sensitivity to be acquired, and the improvement is dramatic. Unfortunately it can be lost in a few seconds of exposure to bright lights.

Eyes have cones that are used for colour vision in daylight, and more sensitive rods that come into their own at night. The rods are not sensitive to red light and this means that if you switch to red illumination (or red ‘Steampunk’ goggles) your eyes can continue to adapt while you move around the boat.

Each eye adapts separately and pirates used to wear an eye patch so that one eye was always adapted to darkness. This enabled them to move easily between the bright Caribbean sunlight and the vestigial gloom below decks.

The bad news for those of pensionable age is that your eyes will only be about a third as sensitive to low light as in your youth. Binoculars will boost illumination by about fifty times and go a long way to redressing the balance; but it still pays to have your youngest crew on lookout.

Paper charts still reign supreme in a number of areas and one of these is the display of lights, and in particular the sectored lights that are so crucial for our safe arrival into harbour.

I simply cannot get on with having a red light at the chart table. The same goes for chart plotter ‘night modes’ where the colour palette is changed to something gothic. I much prefer a very dim white light so I can view charts as nature intended.

A cunning plan

A pilotage plan on a whiteboard in the cockpit is handy for the navigator and crew to refer to and saves countless trips to the chart table. I like to use a book light clipped to the whiteboard. A standard book light is far too bright, but can be made useable with a few layers of primary red nail varnish or a wrap or two of masking tape.

A pilotage plan wants to be the simplest you can come up with that will safely do the job; and with a few backup strategies in case the main one doesn’t work out for any reason.

Don’t assume that a navigation mark is lit, as most, including some cardinal marks, are not.

Yellow buoys (seasonal special marks) may not be there at all, but you are generally pretty safe to assume that port and starboard lateral marks, cardinals, sectored lights and lighthouses are all present and correct.

As with daytime pilotage, you cannot beat a forward or back transit for keeping you on track.

Around harbours most lit navigational buoys will have a visible range of 2-5nm, while main channel markers and important cardinals will have a 5-10nm range and lighthouses can be visible at 25nm.

Cautious sail plan

Moving around on deck should be avoided whenever possible and so it makes sense to only have out sails that are well within the conditions at the time.

In busy areas I also like to have quite a bit of the headsail rolled away as this improves visibility looking forward.

Light spotting

Towards shore the horizon will likely be a confusion of lights and it can be very difficult to spot the one you are after. One trick is to work out the bearing that the light is meant to be on and get the boat heading in that direction. Then the crew can restrict their searching to just 10 degrees either side of the bow, and this narrows the field considerably.

The biggest danger comes from deciding that a light is the one you are looking for simply because you want it to be. The green light you are actually looking for may be as yet too dim to be seen, but a bright alternative on ‘more or less’ the correct bearing must surely be it?

Judging distance can be very tricky as well. Is that a bright light a long way off or a dim one much closer?

Lights can also come up on you in a bit of a rush. On numerous occasions I have been heading for a mark for half-an-hour or so with it seemingly never getting any closer and then suddenly it is 50m off the bow and evasive action is called for. Ships are even worse.

Look behind you

My crew is often surprised by just how few lights are provided in anchorages and rivers. If there is nothing ahead to guide you then full use must be made of back bearings.

For example, the very popular anchorage in Newtown River on the Isle of Wight has no lights at all within, but it does have the smallest lit west cardinal known to man just a few cables out from the entrance.

Fishing pots have been in the news a lot recently with the Cruising Association campaigning for them to be made easier to spot. Whatever happens in the future it is likely that they will always be difficult to see at night, and the crew need to be on their guard and looking ahead on both sides of the hull, especially if under engine.

Silhouettes

Although shore lights can be a distraction for most nocturnal navigation, if you happen to be looking for an unlit buoy or mark (a popular task for Yachtmaster candidates), plan the approach so that the mark is between you and the lights ashore.

A good torch

For close-quarters maneuvering you simply cannot beat having a trusty crew on the foredeck armed with a powerful narrow-beamed torch. They need to be careful never to shine the torch on the deck or headsail, as this will blind everyone on board, but they can quickly earn their rum ration by scanning the torch around to highlight any obstacles that threaten the boat’s safe passage.

One of my first outings as an instructor included a night time pilotage up the river Beaulieu in January. This is a sparsely lit passage at the best of times, but on this occasion there was no Moon and the few navigation lights had been removed for winter maintenance. My fledgling career was saved by the rapid deployment of a ridiculously powerful torch that was able to pick out the red and green reflective marks on the piles in sufficient time before we ploughed into them.

I would be remiss if I did not caution against head torches. They are fine for the person wearing them but are a menace to everyone else.

Sailing at night: common questions for beginners, is it possible to sail at night.

Absolutely. Sailing at night is not only possible but also a unique and exciting experience. With the right preparation and skilled crew, night sailing can be as safe and enjoyable as daytime sailing.

Is Sailing at Night Safe?

Safety is the primary concern for newcomers. We ensure all safety measures are in place, with well-trained crew adept in night navigation and emergency procedures. The sea at night is a different world, demanding respect and caution.

What to do at night when sailing?

Nighttime on a sailing vessel can be magical. Activities range from watchkeeping, navigating, and steering to enjoying the tranquillity of the sea, stargazing, and observing nocturnal wildlife.

How Do You Navigate in the Dark?

This is a key question. Alongside modern tools like GPS and radar, we emphasise the traditional, non-electronic methods. Over 100 years ago, the International Maritime Organisation (IMO) in London developed a system of lights to identify vessels, ships’ lights, and navigation marks, including lighthouses. This system allows sailors, even beginners, to understand what’s around them in the sea, using simple visual cues. We teach our guests to interpret these lights, connecting them to a century-old tradition of maritime navigation.

How do you sail in the dark?

Sailing in the dark involves a combination of using navigational tools, understanding maritime light systems, and relying on the heightened senses and experience of the crew. It’s a skill developed with practice and guidance. Lights are used on the deck and in the rigging when the sails need handling or changing.

How do big ships sail at night?

Larger ships use similar principles as smaller sailing vessels but with additional resources like advanced radar, more extensive crew for watchkeeping, and often more sophisticated weather tracking systems.

What About Sleep and Watchkeeping?

Managing sleep on overnight voyages is a common concern. We use a watch system to ensure there are always alert eyes on deck, balancing rest with responsibility. Learn about the Watches

What Can I See at Night?

The night sea offers a unique spectacle, from bioluminescent trails to starlit skies. Night watches are not just a duty but an opportunity to witness these marvels.

What Should I Wear?

Nighttime calls for practical, warm, and waterproof clothing. Safety gear like life jackets are worn if the skipper requires or you are more comfortable wearing them.

How Do You Deal with Sea Sickness at Night?

Sea sickness can be more challenging at night. We recommend preventative measures and have remedies on hand, advising guests to stay on deck and focus on the horizon or stars.

What If There’s Bad Weather?

We monitor forecasts meticulously and have contingency plans, teaching guests about reading weather patterns and respecting the sea’s moods.

Can I Participate in Night Sailing?

Participation is encouraged. Guests learn everything from steering to sail adjustment, under the guidance of experienced sailors.

What Wildlife Might We See?

Night time brings a different array of marine life, from nocturnal fish to dolphins in the ship’s wake, but it is more difficult to see. You might hear a whale breathing, or a flying fish may land unexpectedly at your feet.

How Different is Sailing at Night Compared to Daytime?

Night sailing feels more intimate and elemental. It’s about the stars, the sound of the water, and the feel of the wind, offering a unique and enriching experience.

Sailing at night is not just a journey across water, but a voyage into a world where traditional skills and modern knowledge meet. It’s an opportunity to connect with the sea in its most enigmatic form and to learn navigation skills that have guided sailors for centuries.

Oh and going off watch after watching a spectacular sunrise for a hearty well earned breakfast is a real treat that few get to experience, enjoy.

Boat Navigation Light Types

Boating Safety Equipment
Types of navigation lights

What are the 5 navigational lights?

Port and starboard sidelights

One of the essential safety features of any watercraft are the port and starboard sidelights. These lights play a crucial role in ensuring the visibility and navigation of vessels, especially during nighttime or low visibility conditions. On the port side, a red light illuminates the surroundings. This distinct red light provides a clear indication of the port side of the vessel. On the starboard side, a green light identify the starboard side of the vessel.

What side does the red and green light go on a boat?

A white light placed at the stern of the boat. This white light is seen only from behind or nearly behind the vessel.

Masthead light

A white light projecting towards the front of the boat.

All-round light

A white light projecting all around the vessel.

What is a navigation light?

Just like for vehicles on our roadways, there are rules that apply to the lights that must be displayed by boats.

These lights provide critical information to the operators of other vessels when they see you. Depending on the lights required to be displayed on your boat based on its length and type of propulsion, the information that these lights provide to others can tell them whether you are at anchor or underway or engaged in some other activity, whether you are a power-driven vessel or not, what your heading is, etc. Other vessels around you make collision avoidance decisions based on the information available to them, that's why it is so important that the information your navigation lights are giving them is the correct information.

If you are caught by the police not showing lights or showing improper lights, you will likely be fined. Worse yet, if the information your navigation lights are providing is incorrect and an accident occurs as a result of this, there could be serious repercussions.

When must navigation lights be displayed?

Navigation lights must be displayed:

At night (between sunset and sunrise)

When periods of restricted (poor) visibility (fog or heavy rain)

What are the rules of navigation lights on boats?

Port and Starboard lights must be visible from one nautical mile, and masthead and stern lights must be visible from two nautical miles.

Boat Navigation Lights rules and requirements

Powerboats navigation lights.

A power driven vessel of less than 12 meters in length, and underway, may display, from sunset to sunrise:

All-round light (white) forward and,

Sidelights (red – green).

Sailboats navigation lights

and underway, may display, from sunset to sunrise:

Sidelights (red – green) and,

Sternlight (white).

Sailboats are considered powerboats when they have the engines on - even if the sails are up.

Masthead light (white) forward,

Sternlight (white).

Commercial boats navigation lights

Police boat lights - Blue flashing light

All law enforcement agencies (Police) and some government agencies must display an all-around blue-flashing beam engaged in duties in Canadian waters.

Tugboat lights - Yellow lights

Is a navigation light used for towing. It's a yellow over a white navigation light placed at the forward end of a towing vessel or vessel being towed.

7 Tips for Night Sailing

By: Pat Reynolds Cruising Tips , Learn To Sail , Safety

Now that we’re into the summer months, lots of you might want to stretch your skill set and do a bit of night sailing. It’s a bit of a different animal so we’ve cobbled together seven things to keep in mind as you head off into the wild black yonder.

Dress accordingly It may be obvious for some, but don’t forget the big ball of yellow heat will be replaced by a cold little white ball that will not help the warmth cause at all. Your ability to enjoy the pleasure that a gorgeous night on the water can provide is directly proportionate to you being dressed for the environment. Don layers, with a spray jacket on top and life should be good.
Carry a decent searchlight Night boating involves becoming accustomed to the available light and acclimating to it. It’s actually one of the cool things to experience during a sail in the dark, so constantly shining a spotlight like you were hand-holding your car’s headlights is not where it’s at. That said, there are instances where having a high-powered light on board can make things considerably safer. Coming into a harbor, verifying a navigational aid or identifying something foreign in the water are all common situations that benefit from a good light.
Stand a watch Of course someone should always be keeping an astute lookout whenever the boat is underway, but this is hyper-important during the restricted visibility that night sailing involves. If you’re lucky enough to have a bright full moon than things are a bit easier but short of that, it’s dark out there folks! Someone needs to keep a mandated watch. By the way, if that person is you, be prepared to have one of the most quality “alone-times” you’ve ever had. People are known to find the meanings of their lives on night watches. You might well return from your nice sail and promptly quit your job, dump that angry spouse and finally get in shape!
Don’t push Many old salts attach a different attitude and mentality for night sails. During the day the fun might be to vigilantly trim and adjust, catch lifts, shift weight and monitor that knot-meter for that rewarding uptick – 3/10s of a knot – Yes! “ Herman are you secretly racing that little boy in the sabot? ” “ No, of course not. ” But Herman is racing that little boy in the sabot! Anyway, at night it’s good to downshift and run the boat at a lower percentage. Enjoy the serenity this time of day has to offer and understand that downsizing the operation a little will make for a safer and more fulfilling experience.
Make sure Waypoints are Clear & Safe Most sailors rely on electronic aids to see them around the waterways and at night they become even more important. They can also, in certain situations, make things less safe. A few years ago, the famous Newport to Ensenada race reported their first deadly accident when a group of sailors ran into a small island off the coast of San Diego. After an investigation, it was determined that the sailors, in all likelihood, didn’t account for the land-mass (island) when they entered in their waypoints. They might have been sleeping or just not paying attention when their cruising boat tragically ran up on the rocks. This would never have happened during the day, but sailing at night brings with it these kinds of considerations.
Know the Light Patterns Fortunately charts and boats are all set up for sailing at night so it’s absolutely essential that the skipper and at least some of the crew know what the language of lights is saying out there. Boats are equipped with lights situated in such a way that other boats can tell what’s going on and charts are filled with light-related information that will clue mariners in on where they are. It can be confusing to look into a harbor located outside of a city and try to understand what is going on. “ Why is that harbor entrance light switching from green to red like that? Oh, that’s Washington blvd… ” Know what to look for and how the lights behave and the confusion will be greatly reduced.
Wear a PFD We understand that not everyone wears their pfd for whatever reason – it’s not comfortable, it’s filthy from lying on the floor for the past month, it sucks away at your already limited sex appeal – we get it. We don’t agree with the decision, but okay. For night boating, swallow your reasoning and put that thing on. Things can get slick on the boat at night and God forbid you end up in the drink, that little pea head of yours is very hard to see in the night. If you’re floating around for a while screaming “over here!” things are vastly better. Attach a battery powered personal beacon/light to it while you’re at it. Follow our advice and should you end up overboard you’ll be back in the boat in no time!

Lynch Yacht Sinking Off Sicily Proves as Baffling as It Is Tragic

As bodies were recovered, the authorities and experts wondered how a $40 million, stable and secure vessel could have sunk so quickly.

By Emma Bubola and Michael J. de la Merced

Emma Bubola reported from Porticello, Italy, and Michael J. de la Merced from London.

Two months after being cleared in a bruising legal battle over fraud charges, the British tech mogul Mike Lynch celebrated his freedom with a cruise. He invited his family, friends and part of his legal team on board his luxury sailing yacht, a majestic 180-foot vessel named Bayesian after the mathematical theorem around which he had built his empire.

On Sunday night, after a tour of the Gulf of Naples, including Capri, and volcanic islands in the Eolian archipelago, the boat anchored half a mile off the Sicilian coast in Porticello, Italy. It chose a stretch of water favored by the Phoenicians thousands of years ago for its protection from the mistral wind and, in more recent times, by the yachts of tech billionaires. The boat was lit “like a Christmas tree,” local residents said, standing out against the full moon.

But about 4 a.m., calamity unfolded. A violent and fast storm hit the area with some of the strongest winds locals said they had ever felt. Fabio Cefalù, a fisherman, said he saw a flare pierce the darkness shortly after 4.

Minutes later, the yacht was underwater. Only dozens of cushions from the boat’s deck and a gigantic radar from its mast floated on the surface of the sea, fishermen said.

In all, 22 people were on board, 15 of whom were rescued. Six bodies — five passengers and the ship’s cook — had been recovered by Thursday afternoon, including that of Mr. Lynch, an Italian government official said, adding that the search was continuing for his daughter.

It was a tragic and mystifying turn of events for Mr. Lynch, 59, who had spent years seeking to clear his name and was finally inaugurating a new chapter in his life. Experts wondered how a $40 million yacht, so robust and stable could have been sunk by a storm near a port within minutes.

“It drives me insane,” said Giovanni Costantino, the chief executive of the Italian Sea Group, which in 2022 bought the company, Perini, that made the Bayesian. “Following all the proper procedures, that boat is unsinkable.”

The aura of misfortune only deepened when it emerged that Stephen Chamberlain, 52, a former vice president of finance for Mr. Lynch’s former company and a co-defendant in the fraud case, was killed two days earlier, when he was hit by a car while jogging near his house in England.

Since June, the two men had been in a jubilant mood. A jury in San Francisco had acquitted both on fraud charges that could have sent them to prison for two decades. There were hugs and tears, and they and their legal teams went for a celebratory dinner party at a restaurant in the city, said Gary S. Lincenberg, a lawyer for Mr. Chamberlain.

The sea excursion was meant as a thank-you by Mr. Lynch to those who had helped him in his legal travails. Among the guests was Christopher J. Morvillo, 59, a scion of a prominent New York family of lawyers who had represented Mr. Lynch for 12 years. He and his wife, Neda, 57, were among the missing.

So, too, was Jonathan Bloomer, 70, a veteran British insurance executive who chaired Morgan Stanley International and the insurer Hiscox.

The body of the ship’s cook, Recaldo Thomas, was recovered. All the other crew members survived. Among them was Leo Eppel, 19, of South Africa, who was on his first yacht voyage working as a deck steward, said a friend, who asked not to be identified.

Since the sinking, the recovery effort and investigation have turned the tiny port town of Porticello, a quiet enclave where older men sit bare-chested on balconies, into what feels like the set of a movie.

Helicopters have flown overhead. Ambulances have sped by with the sirens blaring. The Coast Guard has patrolled the waters off shore, within sight of a cordoned-off dock that had been turned into an emergency headquarters.

On Wednesday afternoon, a church bell tolled after the first body bag was loaded into an ambulance, a crowd watching in silence.

The survivors were sheltering in a sprawling resort near Porticello, with a view of the shipwreck spot, and had so far declined to comment.

Attilio Di Diodato, director of the Italian Air Force’s Center for Aerospace Meteorology and Climatology, said that the yacht had most likely been hit by a fierce “down burst” — when air generated within a thunderstorm descends rapidly — or by a waterspout , similar to a tornado over water.

He added that his agency had put out rough-sea warnings the previous evening, alerting sailors about storms and strong winds. Locals said the winds “felt like an earthquake.”

Mr. Costantino, the boat executive, said the yacht had been specifically designed for having a tall mast — the second-tallest aluminum mast in the world. He said the Bayesian was an extremely safe and secure boat that could list even to 75 degrees without capsizing.

But he said that if some of the hatches on the side and in the stern, or some of the deck doors, had been open, the boat could have taken on water and sunk. Standard procedure in such storms, he said, is to switch on the engine, lift the anchor and turn the boat into the wind, lowering the keel for extra stability, closing doors and gathering the guests in the main hall inside the deck.

12 guests occupied the yacht’s six cabins. There were also 10 crew members.

Open hatches, doors and cabin windows could have let in water during a storm, according to the manufacturer.

The New York Times attempted to reach the captain, James Cutfield, who had survived, for comment through social media, his brother and the management company of the yacht (which did not hire the crew), but did not make contact.

So far none of the surviving crew members have made a public statement about what happened that night.

Fabio Genco, the director of Palermo’s emergency services, who treated some of the survivors, said that the victims had recounted feeling as if the boat was being lifted, then suddenly dropped, with objects from the cabins falling on them.

The Italian Coast Guard said it had deployed a remotely operated vehicle that can prowl underwater for up to seven hours at a depth of more than 980 feet and record videos and images that they hoped would help them reconstruct the dynamics of the sinking. Such devices were used during the search and rescue operations of the Titan vessel that is believed to have imploded last summer near the wreckage of the Titanic.

After rescuers broke inside the yacht, they struggled to navigate the ropes and many pieces of furniture cluttering the vessel, said Luca Cari, a spokesman for Italy’s national firefighter corps.

Finally, as of Thursday morning, they had managed to retrieve all but one of the missing bodies, and hopes of finding the missing person alive were thin. “Can a human being be underwater for two days?” Mr. Cari asked.

What was certain was that Mr. Lynch’s death was yet another cruel twist of fate for a man who had spent years seeking to clear his name.

He earned a fortune in technology and was nicknamed Britain’s Bill Gates. But for more than a decade, he had been treated as anything but a respected tech leader.

He was accused by Hewlett-Packard, the American technological pioneer that had bought his software company, Autonomy, for $11 billion, of misleading it about his company’s worth. (Hewlett-Packard wrote down the value of the transaction by about $8.8 billion, and critics called it one of the worst deals of all time .) He had been increasingly shunned by the British establishment that he sought to break into after growing up working-class outside London.

He was extradited to San Francisco to face criminal charges, and confined to house arrest and 24-hour surveillance on his dime. In a townhouse in the Pacific Heights neighborhood — with security people he jokingly told associates were his “roommates” — he spent his mornings talking with researchers whom he funded personally on new applications for artificial intelligence. Afterward, he devoted hours to discussing legal strategy with his team.

Despite his persistent claims of innocence, even those close to Mr. Lynch had believed his odds of victory were slim. Autonomy’s chief financial officer, Sushovan Hussain, was convicted in 2018 of similar fraud charges and spent five years in prison.

During Mr. Lynch’s house arrest, his brother and mother died. His wife, Angela Bacares, frequently flew over from England, and she became a constant presence in the San Francisco courtroom during the trial.

After he was finally acquitted, Mr. Lynch had his eye on the future. “I am looking forward to returning to the U.K. and getting back to what I love most: my family and innovating in my field,” he said.
