Abstract: A towable watersport board that requires laterally oriented foot bindings. It has an elongated core body and an elongated spar is recessed in its top surface. A plurality of longitudinally spaced apertures having a predetermined configuration are formed in the top surface of the spar and mechanical fastener inserts are positioned in the respective apertures in the elongated spar. The mechanical fastener inserts removably receive screws that secure the foot bindings. The core body is covered by a fiberglass coating.

Abstract: A lightweight wake board binding having a thin bottom support plate. A heel receptacle and a top-of-the-foot retainer strap are secured to the top surface of the bottom support plate by a left and a right side plate stiffener member that substantially eliminates the flex in the bottom support plate produced by the person riding the wake board. The plate stiffeners have upstanding flanges adjacent their inner edges having elongated slots therein that receive a fastening strap for tightly securing the binding to the wearer's foot.
