A water sports device adapted for carrying a rider airborne completely above the surface of the water upon being towed by a tow device. The water sports device comprises an elongated airfoil having a top portion and a bottom portion substantially opposite the top portion, the top portion being adapted for supporting the rider thereon. At least one tow connector is attached to the elongated airfoil, and the elongated airfoil is of a shape which causes it to receive an upward lift reaction from an airstream moving relative thereto upon being towed by the tow device. An elongated spar is provided within the airfoil to which the tow connector is attached. The interior support of the airfoil is, in one embodiment, polystyrene, such as Styrofoam TM and the exterior surface is fiberglass. Alternate embodiments include the provision of pontoons under the elongated airfoil, and the attaching of at least one operable aileron, rudder, and/or at least one downwardly extending fin to the elongated airfoil.
