Abstract
A mooring anchor including a pair of spaced part flukes, an integrally cast tripping palm structure integral with said flukes at the rearward end thereof and including a pair of planar, sloping walls diverting rearwardly from the flukes and first and second pairs of transverse reinforcing walls extending transversely between the sloping walls, an elongated solid stock rotatably received through aligned openings in the reinforcing walls and through the rearward end of a rigid elongated shank having a clevis receiving apertured lug portion at its forward end. The sloping walls of the tripping palm have apertures extending therethrough at positions rearwardly of each surface of each fluke and between the adjacent associated reinforcing walls. The shank has a rearward cross-section transition zone at a position forwardly adjacent the connection thereof with the stock, a forward cross-section transition zone at a position rearwardly of the forward lug portion and a central cross-section transition zone between the forward and rearward zones. The shank has a cross-sectional configuration shaped as a rectangle between the rearward transition zone and the central transition zone and a cros…
