A twin-fluke anchor has a shank, a stock, fluke elements mounted upon the stock to pivot as a unit at the inner end of the shank, each element including a fluke surface in a first plane and a rib generally perpendicular to the first plane, the shank disposed between ribs, and a crown including a pair of flat plates having opposed inner surfaces, each plate supported centrally of the flukes and spaced from the flukes plane and sloping upwardly and rearwardly away from the plane to permit bottom material to flow freely between the inner surfaces of the plates and the flukes. The shank inner end has opposite end surfaces to engage upon respective opposed inner surfaces of the crown plates to limit the range of pivoting movement of flukes, at least one end surface of the shank engaging an opposed inner surface of a crown plate along a line of contact whereby holding load is transferred from the shank to the flukes by a long coupled reaction. Also, each fluke element further includes an integral bracket extension and the crown plates are mounted upon the integral extensions.
