TheAntrim 20 is an Americantrailerablesailboat that was designed byJim Antrim as acruiser and first built in 1982.[1][2][3]
The design was built byAntrim Marine in theUnited States, starting in 1982, but it is now out of production. Henkel reports that it was not in production long and only a small number were built, while McArthur reports, "if any were ever built is unknown".[1][3]
The designer's goals for this boat were to create, "the smallest boat with a workable interior, attractive appearance and eight-foot trailerable beam, and to provide the performance and feeling of spaciousness one might expect in a larger boat."[3]
The Antrim 20 is a recreationalkeelboat, built predominantly offiberglass. It has afractionalsloop rig, araked stem, a plumbtransom, a transom-hungrudder controlled by atiller and a fixed finkeel. It displaces 1,850 lb (839 kg) and carries 750 lb (340 kg) of ballast.[1][3]
The boat has a draft of 4.00 ft (1.22 m) with the standard keel and is normally fitted with a small 2 to 5 hp (1 to 4 kW)outboard motor for docking and maneuvering.[1][3]
The design has sleeping accommodation for four people, with a double "V"-berth in the bow cabin and two quarter berths in the main cabin, under the cockpit. Thegalley is located just aft of the bow cabin. The galley gas a pull-out stove located in a drawer on the port side and a sink on the starboard side. A portableicebox fits under thecompanionway steps. Thehead is a portable type, located under the bow cabin "V"-berth. Cabin headroom is 52 in (130 cm).[1][3][4]
The design has ahull speed of 5.6 kn (10.4 km/h).[3]
In a 2010 review Steve Henkel wrote that the boat is, "probably the best sailer in light and medium air in her [size], combining a deep fin, big sail area and SA/D ratio, and broad waterplane aft ... The same factors that make her a good sailer, particularly in light air, also work against her to some extent in heavy air. She needs a big crew to keep her on her feet in a blow, or if short-handed, she needs to be reefed early. Being deep draft, she is relatively difficult to trailer and launch. Still, overall, we like this design a lot, and are sorry that she was produced for such a short time."[3]
In a July 1981 review inCruising World, the design was described as setting future trends. "With its short overhangs, shallow hull and beam carried well aft, the Antrim 20 resembles a large dinghy with a keel. The enormous rig, reinforces this impression. Sailing performance should be nothing short of exciting ... This is a handsome, exciting little cruiser which should be relatively inexpensive to buy and maintain. This may be the shape of things to come."[4]
