ABSTRACT:
This highly engineered recreational catamaran features a unique pivotable mast with a downward extending section that holds an underwater ballast. A hang glider type sail provides lift as well as thrust. Working in combination with the underwater ballast, the sail functions to deliver a high performance sailboat with high stability and ease of control. The ballast also aids in righting a capsized boat. Advanced three tier hydrolift type pontoons raise the boat partially out of the water under full sail thereby minimizing drag and maximizing speed. A convex deck and optional convex cabin facilitate righting an overturned boat. Other advanced features include retractable daggerboards for turning control, telescoping lower mast for shallow water sailing and beaching, underwater battery powered propulsion for movement in a calm wind and power assisted winches for sail lift and turning control.
