An anchor comprises a shank and a pair of flukes with pointed ends. The flukes are pivotally mounted to a lower portion of the shank so the flukes extend upwardly from the pivot along opposite sides of the shank. The flukes pivot as a unit about an axis through the lower portion of the shank. A counterweight, preferably in the form of a solid metal block, is secured adjacent the bottom of the flukes to pivot with the flukes. The counterweight is mounted on a side of the pivot axis opposite the flukes. Preferably, the counterweight has a weight substantially greater than the combined weight of the flukes to produce a greater moment about the pivot axis than the moment produced by the flukes. Separate pairs of claws project outwardly from each side of the counterweight and are curved generally toward the pointed tips of the flukes. The claws provide frictional contact or drag with the bottom of the water to pivot the flukes relative to the shank so the pointed tips of the flukes penetrate the bottom. Continued pull on a line secured to the shank causes the weight of the counterweight to act downwardly and force the tips of the flukes into the bottom to bury the anchor in the bottom.
