The Ideal 18 is a Canadian trailerable sailboat that was designed by Bruce Kirby as a one design racer and first built in 1989.[1][2][3]
Production
The design was built by Ontario Yachts in Burlington, Ontario, Canada and also by Shumway Marine in Rochester, New York, United States , where production continues. By 1994, 60 boats had been completed and by 2020, 325 boats had been built.[1][3][4][5][6]
Design
The Ideal 18 is a recreational keelboat, built predominantly of fibreglass. It has a fractional sloop rig with aluminum spars and swept spreaders. The hull has a raked stem, a walk-through reverse transom, an internally mounted spade-type rudder controlled by a wooden tiller and a fixed fin keel. It displaces 1,240 lb (562 kg) and carries 700 lb (318 kg) of fibreglass-encased lead ballast. It has built-in flotation for safety.[1][3]
The boat has a draft of 3.25 ft (0.99 m) with the standard keel. The design has a hinged mast for ease of ground transport.[1]
For sailing the design is equipped with a roller furling jib. The seating is on benches moulded into the cockpit sides. The boat has no winches and does not require them. The boat is a displacement, non-planing, design.[3]
The design has a Portsmouth Yardstick racing average handicap of 99.6 and is normally raced with a crew of two sailors, although the cockpit can accommodate four adults.[3]
Operational history
In a 1994 review, Richard Sherwood described the Ideal 18 as, "a strong little keelboat designed for club racing, with rigid rules, such as only one set of sails a year, and no hiking. The jib barely overlaps, is a decksweeper, is self-tacking, and has roller furling. (The roller furling gear is set below deck level.)"[3]
