Harken's Radial Winch provides the perfect balance of secure grip and line longevity with smooth, controlled easing under load. The single speed winch features diagonal ribs instead of textured abrasive materials to maximize gripping power and greatly reduce line wear. The patented angle of ribs drives line wraps down when easing to keep them on the area of the drum that offers the best control. As the winch has a self-tailing mechanism, one crew member can quickly and easy trim or raise the sails.
The winch is smaller yet carries higher loads and offers stress-free seasonal maintenace, with one person installation and easy power upgrades available. Furthermore, Harken's radial winch has high strength composite roller bearings and bushings that reduce friction under load. The load-carrying gears and pins are constructed from 17-PH stainless steel for strength and corrosion resistance.
An adjustable stripper arm is integrated into the winch for safer operation - the arm completely covers the rotating winch top, preventing fingers and clothing from catching in moving parts. The arm adjusts to mulitple positions after the winch is mounted to optimize line exit.
