Abstract
A water sports apparatus is provided, and includes a propulsion device which is provided for the propulsion of the water sports apparatus and whose motor, arranged on the float-body side, is connected in terms of drive to at least one propulsion element via an angularly and/or longitudinally movable propulsion train. The angularly and/or longitudinally movable propulsion train allows the propulsion element to be positioned optimally on the body-of-water side. The motor is arranged in a region which does not cause any body-of-water-side resistance in the operating position with a float body lifted off from the water surface. That part of the water sports apparatus which is situated in the water is optimized with regard to the design which is relevant to flow resistance in the water.
