ABSTRACT:
A marine anchor release mechanism that can be utilized on several pre-manufactured claw, plow or fluke type anchors for unsnagging the anchors from underwater obstructions. The release mechanism consists of two blade type brackets that run parallel to the shank of an anchor and connected to a rear portion of the anchor. A shear pin is installed through the parallel blade type brackets and the shank or an upper extension of the anchor that is sandwiched there between. The release mechanism is designed to release a snagged anchor by applying a sufficient force when powering the boat over the anchor, the shear pin will give way and the anchor assembly will rotate freely from an angle of substantially 180° with respect to the shackle end of the anchor, thus allowing the anchor to pull free from the obstruction.
