The finboard is a muscle powered personal water craft, comprising an elongated buoyant body (the board) and two horizontal fins attached to said body by elastically restrained hinges. When the board is in use, the user stands on its deck, balancing and controlling it by the help of a vertical shaft, securely attached to said deck terminating in a horizontal handle bar. Forward motion is achieved by the user lowering and raising his center of gravity by flexing his knees repeatedly. The board, in reaction to the periodic downward momentum, reacts by alternately sinking deeper into the water then rising higher again. The fins, due to the resulting hydrodynamic pressure against their surfaces, respond to this vertical oscillation by adapting a periodically changing slanted attitude which converts each vertical displacement of the board to a horizontal forward driving momentum. The fact that the fins offer a continuous drive (as opposed to the intermittent drive of paddling) combined with the fact that oscillating fin drives are known to be more efficient than either paddles or propellers, endow this invention with the potential of becoming the fastest muscle-powered water craft.
