The Twitchell 12 is an American sailboat that was designed by Ron Holder as a day sailer for people with limited mobility and first built in 1991.[1][2][3][4]
Production
The design was built by W. D. Schock Corp in the United States, from 1991 until 1993, with 27 boats completed, but it is now out of production.[1][2][5][6][7][8]
Design
The Twitchell 12 is a recreational sailing dinghy, built predominantly of fiberglass, with wood trim. It has a fractional sloop rig with a jib boom, a raked stem, a reverse transom, a transom-hung rudder controlled by a cockpit joystick and a retractable daggerboard. It displaces 165 lb (75 kg).[1][2]
The boat has a draft of 2.00 ft (0.61 m) with the daggerboard extended and 6 in (15 cm) with it retracted, allowing operation in shallow water, beaching or ground transportation on a trailer.[1][2]
The design has a hull speed of 4.41 kn (8.17 km/h).[2]
