The San Juan 24 is an American trailerable sailboat that was designed by Bruce Kirby as an International Offshore Rule Quarter Ton class racer. ^{[1] [2] [3]}

The design was later developed into the more cruising-oriented San Juan 23 in 1975. ^[4]

Production

The design was built by the Clark Boat Company in Kent, Washington, United States, starting in 1973 but it is now out of production. A total of 1200 examples of the design were built. ^{[1] [5]}

Design

The San Juan 24 is a recreational keelboat, built predominantly of fiberglass, with wood trim. It has a masthead sloop rig, a raked stem, a raised reverse transom, an internally-mounted spade-type rudder controlled by a tiller and a fixed fin keel. It displaces 3,200 lb (1,451 kg) and carries 1,650 lb (748 kg) of lead ballast. ^[1]

The boat has a draft of 4.00 ft (1.22 m) with the standard keel fitted and is normally fitted with a small 3 to 6 hp (2 to 4 kW) outboard motor for docking and maneuvering. ^{[1] [3]}

The design has sleeping accommodation for five people. Cabin headroom is 54 in (137 cm). ^[3]

The design has a PHRF racing average handicap of 219 with a high of 231 and low of 216. It has a hull speed of 5.92 kn (10.96 km/h). ^[6]

Operational history

In a 2010 review Steve Henkel wrote, "Don Clark, designer of the San Juan 21 Mk I and II ... and owner of the Clark Boat Company of Kent, WA, went to Bruce Kirby for a hot new racer to be designed to the IOR Quarter Ton Rule. Clark imposed two important restrictions to broaden the market beyond the macho racer group: the boat could not draw more than 4' 0" or be wider than 8' 0", making the boat more useable in shoal waters and making trailering a little easier. Best features: The boat has been a success (and, at least so far, is the most popular quarter tonner ever), with over a thousand sailing, Worst features: Although she is fast and weatherly going upwind, dead downwind in heavy air under spinnaker she can be a little squirrelly, possibly a result of her narrow underbody aft." ^[3]
