This invention pertains to an aquatic stand up board where the rider is standing on the board and provides propulsion by means of a manual hand crank. The hand crank operates two sprockets and a chain causing a double paddle wheel beneath the board to rotate thereby providing thrust. Forward or backward motion depends on whether the manual crank is rotated clockwise or counterclockwise. Steering is achieved by turning the crank in a horizontal plane, similar to a bicycle handlebar, which rotates the paddle wheels in the desired direction.
