Abstract: An inflatable structure that includes continuous longitudinal and axial curves, constructed to form a hydrodynamically designed performance platform for use as a performance water sports board, rescue board, or rescue sled, such as a stand-up paddle board, paddleboard, surfboard, PWC rescue sled, bodyboard, or other floating or dynamic platform. Alternatively, it may be adapted for use with additional structure to provide an inflatable hull and floor for a watercraft, such as a boat, raft, life-raft, rescue craft, or other floating or dynamic platform. Longitudinal stringers welded to opposing panels defining the interior volume of the inflatable structure are joined by welding, gluing, or lashing, and the shape of the stringers and the welding/gluing/lashing schedule can be employed to give the inflatable structure a highly customized curved shape.
