Tie a 3/8-inch polypropylene line, its length greater than the water's maximum depth, to the anchor's tripping ring or crown eye. At the opposite end of the line, attach a small marker buoy. In the event of a snag, pull or carefully motor up to the float bow-first, taking in the anchor rode as you do. Pull upward on the trip line, or opposite the direction the anchor has dug in. It should pull the anchor out crown first.
