A water sport device that enables a person to walk upright over the water consists of a boat-shaped lower part and an upper part between which a chamber is formed whereby the chamber has an inlet and opens out into an outlet. A drive mechanism actuated with the feet comprises two treadles that can be moved up and down, a propeller in the chamber that can be rotated on a vertical axis and the means for transforming the up and down movement of the treadles into a rotational movement of the propeller. The means preferably comprise a bevel gear and two free-wheel bearings.
