Abstract

A wind-propelled craft is disclosed which comprises a hull (1) supporting a pair of unstayed masts (43 and 44) arranged to pivot about an axis lying in an approximately horizontal plane between a first position, in which one mast (43 or 44) extends substantially vertically and the other (44 or (43) extends generally at right-angles thereto away from the hull (1), and a second position, in which the relative configuration of the masts (43 and 44) is reversed. Each mast 43, 44) has a sail (41, 42) attached thereto; whereby, in use, one sail can be trimmed to the wind to provide forward propulsion, while the other sail simultaneously provides upward lift tending to counteract rolling or heeling force applied to the hull (1) by wind impinging on the first sail. A steering control system is also described in which a steering link passes from a control point through the region of the pivot point of a mast to a rudder (2).
