Manually propelled water skis support a person skiing on water. The water ski includes a base having a binding on an upper surface and stationary propulsion structures with uniform height on the bottom surface. The propulsion structures include a rearward facing and vertical propulsion surface and a forward facing and sloped surface such that drag is greater when the water ski is moved rearwardly. The propulsion surface may be arcuate, V-shape, U-shaped, or other shaped in a horizontal plane and may also be circularly concave in a vertical plane. Buoyancy structures may be secured to the upper surface of the base forward and rearward of the binding. Water ski poles including elliptically- or cylindrically-shaped floats at the bottom ends may be used to provide a synergistic increase in waterskiing speed. Straps on the base near the binding may be used to secure the water ski poles to the base in order to form an outrigger.
