Abstract
Abstract A protective tip cover for the sharply angled nose portion of a surfboard for reducing or preventing injury to a surfer or bystander upon impact with the nose portion of the board. Tip covers may be used for any type of surfboard, including those used for wind surfing. The cover comprises an integral relatively soft, resilient (e.g., silicone), member provided with a gently rounded apex portion, a main body portion, and upper and lower extensions. The extensions facilitate attachment of the tip cover to the upper and lower surfaces of the board, while providing the versatility to allow the safety tip to be used with a wide variety of different nose width and thickness boards.
