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.
Claims19
A stringerless surfboard configured to provide a uniform flex pattern, rigidity and reduced overall weight comprising:
- a stringerless foam;
- a generally planar deck portion,
- a generally planar bottom portion,
- a nose
- a tail;
- a left rail and a right rail each outlining edges of the stringerless surfboard from the tail to the nose;
- and
- a set of channels formed on the deck further comprising a pair of adjacent, axially extending elongated concave grooves that meet at their endpoints to form a rigid elongated convex center,
- wherein the set of channels comprises a left set of channels laterally positioned on the deck along the length of the left rail and conforming to a curvature of the left rail, and a right set of channels laterally positioned on the deck along the length of the right rail and conforming to a curvature of the right rail,
- wherein the left set of channels and the right set of channels face and curve in toward each other.

A method for providing a stringerless surfboard configured to provide a uniform flex pattern, rigidity and reduced overall weight comprising:
- providing a stringerless blank foam;
- shaping the stringerless blank foam into a surfboard generally comprising a deck portion, a bottom portion, a tail, a nose, a left rail and a right rail each outlining edges of the stringerless surfboard from the tail to the nose;
- and
- providing at least a set of axially extending channels on the deck,
- wherein the set of axially extending channels comprises a left set of channels laterally positioned on the deck along the length of the left rail and conforming to a curvature of the left rail, and a right set of channels laterally positioned on the deck along the length of the right rail and conforming to a curvature of the right rail,
- wherein the left set of channels and the right set of channels face and curve in toward each other.
