i550 sailboat for sale

Thank you for taking a couple minutes to read about the i550. To  contact us about plans etc., please email us at [email protected] .

The i550 has found a spot in the building sheds and imaginations of hundreds of sailors around the World. It is an 18 foot performance sailboat designed for amateur home builders. The performance is thrilling and has given many sailors memorable days on the water.  i550’s plane in moderate breeze and can be sailed single handed, two crew make it lots of fun, and on windy days three will have thrilling rides. 

The cabin will accommodate two for camp cruising and shelter. 

The i550 was designed with the garage builder in mind. One of the most important considerations for a garage project is “will it fit.” Most garages built in the last 40 years are about 20 feet long inside the door to the back wall. The i550 will fit. Another consideration is that you can park it in the garage when you have finished your build, safe, clean and dry, and not have to pay yard storage fees. It is easily towed with a normal sedan, a great advantage for the family and your sailing horizons are unlimited.

The primary building materials are 1/4” (6 mm) marine plywood, epoxy, fiberglass and carbon fiber. The shape of the boat has been drawn with simplicity in mind and has roots in historic Long Island Sound Sharpie oyster boats. The oyster boats were simple and fast with a heavy load of oysters. First back to the packing house got the best price. 

A race for the money every day was a real stimulus for building fast hull shapes. 

The name Sharpie defined them. 

The founders of West System Epoxy, Jan and Meade Gougeon, built  an i550 for themselves, remarking on the power ratio of the i550 expressed as sail area to wetted surface area. There is a great amount of horsepower to weight, period. They filmed themselves building their i550  “Hot Canary",  for the Everglades Challenge and edited it down to 3 minutes from 12,000  frames.

Wood is an outstanding engineering material, period. Epoxy is an outstanding glue and waterproof coating, used throughout the construction the boat. Each part of the boat is coated with epoxy on all surfaces to exclude moisture. When mixed with different additive powders epoxy can be thickened to form structural peanut butter consistency for joints or smooth as silk fairing putties for painted surfaces. Dry wood lasts forever, go ask the Egyptian Pharos. 

Boats built using epoxy/wood composite 40+ years ago are as strong as the day they were launched.  Boats built this way last as long or longer than fiberglass boats and remain stronger longer. 

They smell better, too .

There is an active facebook page for this class as well.

Great boat for fast day sailing and camp cruising, racing, phrf. Large cockpit can accommodate a crew or can also be singlehanded. The Gougoen brothers (West System Epoxy) built a very nice example for the Everglades challenge called Hot Canary. Some good articles floating around out there on the speed and success of this boat.

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)

Have you always wanted a performance sportboat, but didn’t have a performance sportboat wallet? The original i550 was created for the MicroTon class, and has since been upgraded and redrawn as a one-off sportboat for fleet racing.

It’s ease of building for the amateur builder with “stitch-and-glue” method ensures a light, solid hull, and a quick build for even those with NO boat building experience.

i550 sailboat for sale

Due to it’s simple construction method, there’s not much to the construction process. The whole thing can be cutout, and “stitched” together in a weekend. The construction process is fairly simple and straightforward; The wood panels are cutout and “stitched” together in a string jig to keep the boat symmetric. Once the boat has been stitched, the open hull is left right side up, and the seams glued with glass tape and epoxy. Frames are set in the boat, and taped with epoxy in place. The whole interior can then be epoxied and finished before adding the decking.

Decking comes next, then the hull exterior itself. The boat is still light enough in this stage that it can be easily turned over with the help of come friends. The bottom faired and finished and the hull turned back upright. Rigging is added, and any interior details come next. Sounds simple? That’s because it is. Total build time is typically about 200 man hours.

There is room down below for simple accommodations, and “camp style” sleeping. Plenty of room on deck ensures comfort both up and downwind. A bulbed keel gives stability and righting moment while allowing the boat to keep dinghy like performance.

The plans pack consists of: Construction Notes, Suggested Bill of Material, profile, plan and section views, nesting diagram, hull panel diagrams, frame diagrams, interior piece diagrams, keel and keelbox diagram, rudder diagram, cabin trunk diagram, deck layout diagram, and a rigging diagram. The plans pack is all A sized drawings in a easy to work with binder. Plans include both the standard, and extended cockpit version.

The rig can be obtained through a number of sources. We’ve put together a rig package for North American builders available upon request. Additionally, we plan to offer hull kits, and keel bulbs in the not so distant future. Check back soon for more information.

i550 sailboat for sale

This boat has been built in 3 sizes, ranging from the i550, to the MG25, to the MG30. Plans are currently being redrawn for the latter two models and will be available soon. There are also a number of other designs coming; a smaller 15 foot sportboat, that is in the works, check back in the coming months for more details on these projects.

This is a great way to afford a high performance sport boat at a fraction of the cost of other offerings of this type of sailboat. If the builder is resourceful it can be sailing for less than $5,000. If the builder uses all the best brand new sails, mast, hardware and a trailer it can be sailing for $9,000.

It is fast, speeds in excess of 16 knots are quite possible!

Several of the photos in this article were submitted by Andrew Clauson in Australia. Andrew built the boat in a few seasons time, and will be racing other 6m sized sportboats. For more information on Andrew’s project you can visit his website at:
