Patent ID: 8333630

Claim:
An apparatus for enhancing the performance of a surfboard, the surfboard having a top surface, a bottom surface, and a peripheral surface situated between the top surface and the bottom surface, each surface having a topographic shape, the surfboard further having a back end, a front end, and two sides situated between the front end and the back end, the apparatus comprising: an elongated flexible structure a main portion of which has a generally uniform L-shaped cross section with two legs meeting each other at a vertex, each leg having an leg inner surface and a leg outer surface, the leg outer surfaces meeting each other at the vertex at an angle, the leg inner surfaces meeting each other to form a main structure inner surface, the main structure inner surface having a topographic shape which is complementary to the topographic shape of a portion of the peripheral surface of the surfboard and a portion of the bottom surface of the surfboard adjacent to the portion of the peripheral surface; and means for attaching the main structure inner surface to the portion of the peripheral surface and the portion of the bottom surface of the surfboard; the elongated flexible structure further comprising: a second portion having a second portion inner surface and a second portion outer surface which is parallel to the second portion inner surface, the second portion inner surface having a topographic shape which is complementary to the topographic shape of a second portion of the peripheral surface and a second portion of the bottom surface adjacent to the second portion of the peripheral surface; a connection portion connecting the second portion of the elongated flexible structure to the first portion; and means for attaching the second portion and the connecting portion to at least one of the peripheral surface, the bottom surface, and the top surface of the surfboard; wherein at least one of the means for attaching the main structure inner surface to the portion of the peripheral surface and the portion of the bottom surface of the surfboard and the means for attaching the second portion and the connecting portion to at least one of the peripheral surface, the bottom surface, and the top surface of the surfboard utilizes at least one material selected from the group consisting of urethane adhesives, epoxies with resin content producing a flexible bonding joint, rubber cement, silicone adhesive, and adhesives which are applied and set up at temperatures higher than an ambient temperature.
