Abstract: A lightweight surfboard that is rigid yet provides uniform flex characteristic without the use of a traditional wooden stringer includes a stringerless blank foam and a set of channels shaped into a top portion of the body of the surfboard. The set of channels comprises a pair of adjacent, axially extending elongated concave grooves that run along the length of the set of channels, meet at their end points and form a convex center section. The convex center section of the set of channels provides the support to prevent the board from breaking due to the bending of the surfboard while being ridden on the wave. A laminating layer may be glassed on the set of channels for additional strength. The laminating layer may include fiberglass cloth, Kevlar, carbon fiber or any suitable material.

Abstract: A stringer for use in a board comprising an internal core and an outer skin, the stringer comprising a first compressible side member adjacent the outer skin on a first side of the board and a second compressible side member adjacent the outer skin on a second opposite side of the board. A central member is provided extending from a location adjacent the first member to a location adjacent the second side member, the first and second side members being relatively flexible in relation to the central member. Longitudinal flexing of the board results in compression of the first and second side members by the central member such that as the amount of flexing increases, the force transferred through the first and second side members from the outer skin to the central member increases, thereby increasing the stiffness of the board.
