ABSTRACT:
A plan for a sail of a sailing craft such as a sailboat, an iceboat and a land yacht having a hull. At least one mast is mounted on an end of the hull and the mast angles upwardly over the hull. A boom is pivotably mounted approximately amidships of the hull. The boom is rotatable through 360.degree. about the mounting point, and the ends of the boom avoid contact with the at least one mast. A triangular sail has a lower edge connected to the boom and an upper corner releasably connected to the top of the at least one mast. The boom, preferably, has an upper member and a lower member. The upper member is rotatable, and the sail may be roller reefed about the upper member. A steering system for the vehicle is provided which is collocated with the controls for the sail whereby the vehicle may be controlled by one individual at a single location. In a catamaran type sailboat, a control ring is connected to the boom whereby pivotal and rotational movement of the sail may be controlled by a person seated on the hull.
