ABSTRACT:
In a sailboat having a sail such as a Genoa jib with roller reefing for spirally winding the sail on a fairing around a stay, a winch mechanism for turning the fairing about the stay and spirally winding the sail to and from the fairing is disclosed. The winch includes a high mechanical advantage clutch, preferably a cone clutch, normally engaged by load between the sail and sheet exerting an unwinding force upon the fairing through the normally engaged clutch to a normally stationary clutch driving shaft. The clutch driving shaft has a first clutch member ratchetted from the vessel to permit turning of the entire clutch for taking in of the sail. The clutch includes a second clutch member attached for rotation with the fairing relative to the vessel and driven for both sail take-up and let out by the normally stationary clutch driving shaft. The normally stationary clutch driving shaft is in turn driven usually by a hydraulic motor or upon motor failure by a ratchetted winch handle.
