Abstract
Abstract A marine fender assembly for protecting a wall from impact, including a frontal plate spaced from the wall and one or more fender bodies disposed between the frontal plate and the wall. The fender body is made of elastomer and comprises a hollow cylindrical portion and a pair of flanges which are integrally formed with the cylindrical portion at opposite ends thereof. One of the flanges of the fender body is secured to the wall in such manner that the axis of the fender body extends at right angles to the wall. The frontal plate is secured to the other one of the flanges of the fender body.
