Abstract: A wing structure for hang gliders, ultralites, gliders, heavy aircraft, ornithopters and sailsoaring flying boats which has a first wing set that pivots on two axis, and a second wing set that remains substantially immobile relative to the fuselage or keel. The wing pivots on the lateral axis of the fuselage or keel by moving along a slider assembly that allows it to move from a swept position to a more perpendicular position relative to the keel to control the amount of lift. The wing also pivots on the longitudinal axis of the fuselage or keel to control banking. On hang glider versions of the device, optional ducted fan, propeller, or jet propulsion units provide power to maintain flight. An optional bungee launch assembly assists takeoff from relatively flat surfaces. An optional "telepresence" wing controller allows the pilot to control wing motion with minimal physical exertion.

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.
