摘要： Disclosed is an anchor having a fluke, a shank that is connected to the fluke, and a coupling to attach the fluke to an anchor line or anchor chain, wherein the shank has two shank legs each having a straight shank plate with an outer surface that extend on the opposite sides of the plane of symmetry of the anchor and that diverge from the coupling towards the fluke, wherein the fluke has two straight penetration plates with a top surface on the opposite sides of the plane of symmetry of the anchor, wherein the orientation of the outer surfaces with respect to the top surfaces is specified by three angles under narrow ranges to provide excellent penetration properties and an excellent holding capacity.
