HARKEN WINCH 3SPD RADIAL SELF TAILING 70.3

Harken Radial Line winches have successfully balanced the need for a secure grip and line longevity with smooth, controlled easing while under load. Details sailors will appreciate: smaller winches that carry higher loads, stress-free seasonal maintenance, and one-person installation with easy upgrades to power. Patented angle of ribs drives line wraps down when easing to keep them on area of drum that provides best control. 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.

The Radial winch drums gripping surface is shaped for each winch size and drum material and features diagonal ribs (rather than textured abrasive materials) to maximize gripping power and greatly reduce line wear. The self-tailing mechanism on the winch means that one crew member can quickly and easily trim or raise sails.

The Radial winch range has sizes suitable for halyard and sheet winches on most cruisers and cruiser-racers.
