发明名称 Dynamic current propulsion for water boards
摘要 Disclosed herein is a method of water board propulsion comprising placing a buoyant board with a flexible water catching pocket having an open proximal end and at least a partially closed distal end affixed to a bottom surface of the water board in a current of water moving at a speed which is faster than the buoyant board; positioning said open proximal end to receive the flowing water; receiving water flow into the open proximal end; and, accelerating the board in the direction the current with greater acceleration than the same board without a water catching flexible pocket.

主权项 1. A method of water board propulsion, the method comprising: placing a buoyant water board equipped with a bifurcated flexible water-catching pocket in a current of flowing water, said bifurcated flexible water-catching pocket affixed to a bottom surface of the water board and having an open proximal end and at least a partially closed distal end and comprising strips that bifurcate the pocket so as to limit the downward movement of bottom of the pocket; and said current of water moving at a speed which is faster than the water board; positioning said open proximal end of the bifurcated flexible water-catching pocket to receive the current of flowing water thereby allowing the current of flowing water to flow into the open proximal end and expand the bifurcated flexible water catching pocket and accelerating the board forward with an acceleration greater than the same water board, but without the bifurcated water catching flexible pocket, would experience under otherwise identical conditions.
