ABSTRACT:
A power or manually operated winch mechanism for handling the running rigging lines of a sailing yacht. The winch includes a winding drum, which winds and stores the line during line retrieving operations and controllably releases the line when desired. The new winch, while intended to be driven by on-board electric or hydraulic power, includes a novel mechanism, actuated by a conventional winch handle, for converting the winch to a multi-speed manual operating mode in the event of failure of the on-board power system. A clutch mechanism enables controlled release of line from the winding drum during manual operation, and enables adjustments and emergency release operation when operating in a power mode. Novel level wind features enable the lines to be appropriately tensioned during retrieval, and positively drawn from the drum when the line is not under load. Significant improvement in the safety and convenience of the crew is enabled.
