Abstract

Abstract A protective tip cover for the sharply angled nose portion of a surfboard for reducing or preventing injury to the user upon impact with the nose portion of the board. The cover comprises a relatively soft, resilient (e.g., silicone), generally V-shaped member provided with a gently rounded apex portion and a pair of rearwardly extending wing portions which merge into side surfaces of the board. Upper and lower surfaces of the board are provided with slots extending from the juncture of the wing portions toward the apex. An after market kit is also provided for enhancing the safety of existing boards. The kit includes a surfboard tip cover, suitable primer and adhesive, applicators and installation instructions.
