A sailing vessel (10, 26 and 28) has an underside (14) with a pair of angular planar lift surfaces (30 and 32) for bringing the vessel (10, 26 and 28) to a planing mode and providing pitch stability, while under way. The vessel (10, 26 and 28) further has a pair of controllable boards (56 and 58), one for each lift surface (30 and 32), for providing lateral resistance to drift. Manipulation of these boards (56 and 58) in the same direction permits lateral movement of the vessel (10, 26 and 28) without changing its heading in order to provide rapid adjustment to heeling and righting imbalances, thereby permitting larger sail (28) areas. Lateral movement also can be used to keep the hull (10) pointing at a slightly higher angle into the wind than its actual direction of motion, thus utilizing the sides (16 and 18) of the vessel (10, 26 and 28) as additional sail area. The control mechanism (70, 72, 74, 76, 78, 80, 82, 84, 86, 88, 90 and 92) for the boards (56 and 58) includes a handle (94) which is rotated to change the heading of the vessel (10, 26 and 28) and/or moved inboard or outboard to laterally adjust the vessel (10, 26 and 28). |
