Abstract
Abstract A mooring anchor made up of a solid, heavy, cylindrical body from which extend rigid upper and lower cross arms that have flukes at the outer ends. The cross arms are spaced at ninety degree intervals around the circumference of the body. The upper cross arm is located appreciably higher on the body than is the lower cross arm. An eye affords a convenient means of attaching a chain or cable. This anchor is intended to provide a good means of anchoring buoys to bottoms that are either of sand or mud. It has no moving parts.
