Reversible winch ratchet mechanism
 A mechanical winch includes a ratchet lever having a single pawl which may be positioned in either one of two orientations in order to preclude clockwise or counterclockwise movement of the winch, drum or reel. In each orientation, the ratchet lever may also be positioned in a free wheeling position for the drum.
