Abstract: A water vehicle (10) has a stabilizer and accelerator device in the form of an elongated strip (20). The strip is designed to be sleek so that the water vehicle is not stiff and difficult or awkward to operate. Yet, the strip sufficiently protrudes outwardly and downwardly from the bottom of the water vehicle to influence the flow of water across the water vehicle resulting in increased speed, control and stabilization of the water vehicle. The strip has a cross section that is triangular in shape, but with curved side walls. The strip grips the water during turns for greater control and maneuverability and accelerating out of the turns.

Abstract: The surf riding craft is a shaped water surfboard which has a prestressed center stringer with a foam core element located on each side of the stringer to form a center core element. The bending of the stringer at the tail end in manufacture creates a spring condition tending to force the surfboard back to the original straight position. There is a patch layer bonded to the top and bottom of the center core element for added strength yet relatively more flexibility of the midsection element section compared to the nose and tail sections of the craft. The craft is then covered by the bonding of a top skin and a bottom skin. Three fins are mounted near the tail of the craft. This construction provides for bending and torsional motion about the midsection element of the craft to provide better performance in surfing waves.

Uses of the foam structures include, but are not limited to, packaging materials, gym mats, body boards, or eaves fillers.
