ABSTRACT:
A bodyboard for riding ocean surf is provided which includes a layer of stiffening material beneath the outer skin of the board in selected regions of the board. The stiffening material is in the form of one or more layers of open-weave or open pattern, crosshatched fiber mesh laminated into the semi-rigid foam which makes up the majority of the board's interior. The stiffening material is preferably located adjacent the bottom skin of the board in order to resist or inhibit creasing of the planing surface on which the board rides. The board retains sufficient flexibility for maneuvering and for comfort, while resisting bottom skin damage due to stresses exerted on the board in use. Alternative embodiments of the invention include using stiffening mesh beneath the side rails of the board and using one or more additional layers of stiffening mesh in selected regions between the foam core and the outer skin of the bodyboard.
