Ghost 13 is a 13 ′ 3 ″ / 4 m monohull sailboat designed by George Larsen and built by Janus Inc.(USA) starting in 1964.
Rig and Sails
Auxilary power, accomodations, calculations.
The theoretical maximum speed that a displacement hull can move efficiently through the water is determined by it's waterline length and displacement. It may be unable to reach this speed if the boat is underpowered or heavily loaded, though it may exceed this speed given enough power. Read more.
Classic hull speed formula:
Hull Speed = 1.34 x √LWL
Max Speed/Length ratio = 8.26 ÷ Displacement/Length ratio .311 Hull Speed = Max Speed/Length ratio x √LWL
Sail Area / Displacement Ratio
A measure of the power of the sails relative to the weight of the boat. The higher the number, the higher the performance, but the harder the boat will be to handle. This ratio is a "non-dimensional" value that facilitates comparisons between boats of different types and sizes. Read more.
SA/D = SA ÷ (D ÷ 64) 2/3
- SA : Sail area in square feet, derived by adding the mainsail area to 100% of the foretriangle area (the lateral area above the deck between the mast and the forestay).
- D : Displacement in pounds.
Ballast / Displacement Ratio
A measure of the stability of a boat's hull that suggests how well a monohull will stand up to its sails. The ballast displacement ratio indicates how much of the weight of a boat is placed for maximum stability against capsizing and is an indicator of stiffness and resistance to capsize.
Ballast / Displacement * 100
Displacement / Length Ratio
A measure of the weight of the boat relative to it's length at the waterline. The higher a boat’s D/L ratio, the more easily it will carry a load and the more comfortable its motion will be. The lower a boat's ratio is, the less power it takes to drive the boat to its nominal hull speed or beyond. Read more.
D/L = (D ÷ 2240) ÷ (0.01 x LWL)³
- D: Displacement of the boat in pounds.
- LWL: Waterline length in feet
Comfort Ratio
This ratio assess how quickly and abruptly a boat’s hull reacts to waves in a significant seaway, these being the elements of a boat’s motion most likely to cause seasickness. Read more.
Comfort ratio = D ÷ (.65 x (.7 LWL + .3 LOA) x Beam 1.33 )
- D: Displacement of the boat in pounds
- LOA: Length overall in feet
- Beam: Width of boat at the widest point in feet
Capsize Screening Formula
This formula attempts to indicate whether a given boat might be too wide and light to readily right itself after being overturned in extreme conditions. Read more.
CSV = Beam ÷ ³√(D / 64)
Spinnaker 142 sq. ft.

 | | | Please support our sponsors and let them know you heard about their products on Cruisers Forums. | | 08-09-2013, 20:23 | | | | got loosened and fell off on the road while driving. After hours of searching for it, on the road and a new one (online and locally in NE OH), I can't find what I need. Does anyone know of any places for finding for small sailboats like this? It has a 3/32" cable, 1/4" pin, and what measures to be a 7/32" thread 28 thread per inch turnbuckle. West doesn't have any, and I'm thinking I may have to buy something new and attach (swedge?) it to the cable. Is that hard? I just was having trouble even finding threads to match up to it at any local stores to rig anything up, and I know its pretty critical to be strong enough since it's keeping the up.
Thanks for any help and suggestions.

Review of Ghost 13Basic specs.. The hull is made of fibreglass. Generally, a hull made of fibreglass requires only a minimum of maintenance during the sailing season. And outside the sailing season, just bottom cleaning and perhaps anti-fouling painting once a year - a few hours of work, that's all. The boat equipped with a fractional rig. A fractional rig has smaller headsails which make tacking easier, which is an advantage for cruisers and racers, of course. The downside is that having the wind from behind often requires a genaker or a spinnaker for optimal speed. CentreBoard The Ghost 13 is equipped with a centreboard keel. A centreboard keel is a pivoting lifting keel, allowing to sail both coastal and inland waters. The boat can sail close to the beach as the draft is just 0.15 - 0.25 meter (0.49 - 0.79 ft) dependent of the load. See immersion rate below. Sailing characteristicsThis section covers widely used rules of thumb to describe the sailing characteristics. Please note that even though the calculations are correct, the interpretation of the results might not be valid for extreme boats. The immersion rate is defined as the weight required to sink the boat a certain level. The immersion rate for Ghost 13 is about 31 kg/cm, alternatively 173 lbs/inch. Meaning: if you load 31 kg cargo on the boat then it will sink 1 cm. Alternatively, if you load 173 lbs cargo on the boat it will sink 1 inch.

New to group : janus ghost 13I'm new to this world and got a free ghost 13 as my first personal boat. I've done some sailing but usually as a passenger or 'hey grab that line and pull' sorta deal. I'm looking forward to learning more about the ins and outs of sailing. I'm in south eastern portion of Iowa so my main spots are red rock, Rathbun, saylorville and Macbride. I'm also looking for a centerboard or dagger board (?) for my boat and if possible a new boom as mine is a kinda ok replacement the previous owner rigged up but sold without a centerboard. Any help or advice for parts would be greatly appreciated or even good pictures or measurements so I could make my own?  Welcome! I grew up in Iowa City and remember good times on the water at Rathbun and MacBride. That daggerboard shouldn't be too difficult to fabricate. Plenty of how-to videos on Youtube. You can get an idea of the shape here ( https://sailboatdata.com/sailboat/ghost-13 ) and from the many pics online. Hi I have a Ghost 13 and trailer in our yard but I'm 4 or 5 hours away near Chicago. Are you interested in it for parts? I'd prefer to sell complete - come and tow away!  Hello. I am interested in the Ghost 13. I'd take the whole thing if the parts I need are in decent condition. Thank you, Kirk Welcome from another new member, and best of luck getting your new boat outfitted. Cheers, Annapolitan Top Contributors this Month | Go to

A boat with a BN of 1.6 or greater is a boat that will be reefed often in offshore cruising. Derek Harvey, "Multihulls for Cruising and Racing", International Marine, Camden, Maine, 1991, states that a BN of 1 is generally accepted as the dividing line between so-called slow and fast multihulls.

At the same time, Janus plastics went into production with the Ghost 13. A video Janus released to dealers soon after the regatta showed the ghost being easily lifted onto a car top carrier, and showed 5 people sailing comfortably down the lake in light wind. The boats name "Ghost" was derived for the term ghosting along in light wind.
