Abstract

Abstract The rubber fender (1) for ship comprises an impact receiving section (2), lateral wall sections (3) extending from the impact receiving section and fitting sections (4) attached to the tips of the lateral wall sections, all the sections above-mentioned being made of rubber alone. Only the top surface (2a) of the impact receiving section or both the top surface of the impact receiving section and the surfaces of the lateral wall sections are coated with coating layers (5) of poly­urethane elastomer having a thickness of 2 to 20 mm. The fender may be colored as desired and may be im­proved in abrasion resistance. The fender may improve the safety of a ship coming alongside the pier, and prevent the ship from being soiled. The fender may also improve the beauty of the pier.
