A water sport device for supporting a seated human rider while the rider and the device are towed behind a powered water craft, including an elongate board to which a seat and foot holder are secured, an elongate hydrofoil extending downward from the board and a planing blade secured to the hydrofoil generally parallel to the board so that the planing blade provides essentially no lift when the board is horizontal. The seat is secured to the board by a shock absorbing means to cushion the impact forces on the rider. The positioning of the seat and the planing blades at the rear of the board, the use of a single vertical hydrofoil, the size of the planing blade and the positioning of the foot holders at least two feet in front of the seat provides a water sports device which is relatively easy to ride, while at the same time being highly maneuverable and capable of high jumps.
