A boat or ship anchor having a crown portion with a spaced apart pair of flukes projecting forwardly therefrom in the same plane, and a pair of tail plates extending rearwardly therefrom, the tail plates being splayed to present a large frontal area. Intermediate the flukes and extending through the crown is an aperture. A shank element, adapted for attachment to the anchor line at its forward end, extends through the aperture and is dimensioned for sliding relation in the aperture intermediate the flukes. A projection in the form of a minor fluke on the tail end of the shank element limits the sliding motion of the shank through the aperture in a first direction while permitting limited rotational or angular movement thereof relative to the flukes and crown at least in a plane perpendicular to the plane of the flukes. In operation, with tension on the anchor line or chain, the minor fluke holds the shank to the crown, while the flukes and the tail plates combine their functions to provide increased holding powder without overly deep penetration of the bottom. When it is desired to release the anchor from the bottom, the anchor line tension being reversed, the shank element slides through the aperture, the minor fluke impinging upon or into the bottom acting as a fulcrum about which the shank rotates, the shank acting as a lever to pull the flukes from the bottom along the same line of action as they entered. In the event of accidental release of the anchor, the action is as described above, the flukes then flipping or rotating about the shank element and burying themselves into the bottom on the opposite side in the direction of tension of the anchor chain connected to the shank element.
