ABSTRACT:
A three hulled sailboat consists of a tripod frame having three generally horizontal spars which define support points at their distal ends. During the sailing of the boat, one support point is always toward the windward, and the other two support points are leeward. A generally vertical mast supported on the frame has a masthead spaced equidistantly from the two lee support points and generally above the windward support point. Three buoyant hulls are coupled to the respective support points, the hulls being elongated with a high length-to-beam ratio, and being symmetrical about a transverse vertical plane for movement through the water in either direction. The hulls are coupled for independent rotation and steering relative to the frame and also for independent pitching relative to the frame about transverse central axes. Independent steering is provided for each of the three hulls relative to the frame. The boat sail is mounted generally in a plane defined by the two lee support points and the masthead; and the lower end of the sail is secured to a roller boom rotatably supported generally between the two lee support points. The sail is reeved by being taken up on the roller boom, and is raised by a halyard reeved over the masthead; and the sail is readily raised and reefed by the pilot so that any desired area of sail may be presented to the wind.
