ABSTRACT:
A watercraft (10) operates as a conventional displacement vessel or as an airborne craft. In the airborne mode water is drawn upward through a drogue (18) by operation of a pump (42) which is driven by a motor (44). Pressurized water from the pump (42) is directed downward as water jets by nozzles (64-70). The reaction force on the nozzles (64-70) serves to lift the watercraft (10) above the surface of a body of water (16). The watercraft (10) is further equipped with fore and aft nozzles (84, 90) as well as transverse nozzles (86, 88) to provide full directional control and propulsion for the watercraft (10). A control computer (100) operates through a bus (102) to position the drogue (18) as well as control the thrust produced by the nozzles (64-70) and (84-90). The altitude of the watercraft (10) is measured by altimeters (94, 96). The height of forereached waves is measured by a wave height radar (92). The watercraft (10) can operate essentially free of friction with the water (16), can pass over obstacles such as rocks, and can land inland beyond the edge of the water (16).
