Three-speed self-tailing winches are ideal sheet winches on larger boats. Coupled with Harken's® large drum diameters, three-speed self-tailing winches offer very high line speeds for racing or fast cruising, even in heavy conditions. Self-tailing allows one crew member to handle the entire trimming task-perfect for cruising or racing boats.

First gear is selected by depressing the nameplate ring next to the winch handle socket. The winch then auto-shifts from first to second to third on successive crank direction of rotation changes. Use first gear for fast sheet trimming in light to moderate air.

All large three-speed winches offer drums supported by ball bearings, two gears driving the drum, 17-4 PH stainless shaft pins, and roller bearings on all gears.

By special order, the B74.3 can be provided with power ratios of 85:1 or 92:1 for use on high loads such as found on very large boats or multihulls.
