ABSTRACT:
The present invention is a marine winch having a tension limiting clamp ring thereon, to permit the safe release of a line or halyard when forces become too great therewith. The winch has a base for attachment to a boat. A central driveshaft is supported on the base. A drum is disposed about the driveshaft. The drum has an upper flange and a lower flange thereon, the drum being arranged to receive a line thereabout. The upper flange has an inner hub disposed about the upper end of the driveshaft. A clamp ring is arranged about the hub, the clamp ring and the upper flange having opposed outer annular surfaces thereon arranged to receive a line therebetween. The clamp ring is movable with respect to the upper flange and the hub to provide a limitable force on a line disposed between the outer annular surfaces of the flange and the clamp ring.
