Abstract
Abstract An improved anchor is of conical construction, and has at its larger diameter end a groove which is adapted to receive therein an annular ''''O'''' ring which protrudes beyond the outer surface of the anchor to provide a bumper which protects the sides of the boat against damage as the anchor swings against the sides of the boat.
