Harken 70 Hydraulic Self-Tailing Radial Bronze Winch — 3 Speed, Vertical

Hydraulic Radial winches let you relax in luxury and trim any size sail with the push of a button. The self-tailing mechanism on the winch means that one crew member can quickly and easily trim or raise sails. High-strength composite roller bearings and bushings reduce friction under load. Load-carrying gears and pins are 17-4 PH stainless steel for strength, corrosion resistance. Motors attach to central drive shaft and drive through winch gears for two-speed mechanical advantage. Low-power first gear for fast trimming; higher-power second gear for fine-tuning loaded sheets. Efficient design allows smaller motor size. Material Bronze
