Boat anchor
 A boat anchor which is characterized by a generally triangular-shaped, solid base provided with a wedge-shaped frontal portion or blade and a cavity located in the top portion of the base, the cavity open at the top and extending to the blade and pivotally receiving a lever for attaching an anchor rope to the boat anchor. The boat anchor blade is designed to wedge into the sand or mud water bottom or to engage an underwater obstacle such as a rock, responsive to tightening of the anchor rope and pivoting of the lever with respect to the anchor base at an angle which is determined by the depth of the water and the length of the anchor line.
