Abstract: A boat anchor and a retrieving mechanism for unsnagging the anchor from an underwater obstruction. The anchor includes an anchor body and a shank pivotally connected to the anchor body. The retrieving mechanism includes an elongated shank line connected between the crown and one end of an elongated clampbolt of an adjustable release mechanism. A clampbolt receiving block having a U-shaped channel is connected to a distal end of the shank which is aligned longitudinally to the shank and opening away from the anchor body. An enlarged shoulder of the clampbolt abuts against one end surface of the receiving block while an elastomeric friction member and a hand nut are positioned on a threaded portion of the clampbolt against the other end surface of the receiving block.
