ABSTRACT:
A sailing craft having hydrodynamically shaped catamaran hulls and tapered configuration rudder assemblies attached to each hull. Low draft keels are attached to the fore one-half bottom portions of the hull and a pitch-sensitive variable camber mast and main sail assembly is rotatably mounted on a cross-beam framework which interconnects the two hulls. The mast is constructed and rigged to bow with respect to the longitudinal plane of the sailing craft which passes through the roll axis in response to a high velocity wind force. The bow decreases as the wind velocity decreases and the mast rotates to form a camber adjustment through use of battens attached to the main sail sheet(s). The rudder assembly and control bungy cords and lines permit selective raising and lowering and automatic raising upon contact with underwater obstacles. The deck structure provides for quick dismantling and ease of sailing. Novel shroud line cleats are incorporated into the rigging and the hull has a textured surface which promotes wetting by water for higher sailing speeds.
