Harken Winch Selection Guide
Aluminum Radial® winches are designed for sailors who want lightweight, extremely strong winches with plenty of power.
The Radial winch drum’s 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. When easing, the angle of the ribs stops line from rising, preventing overrides and providing a smooth, controlled release as the line exits the winch. Aluminum drums and high-strength composite self-tailing jaws and skirt save weight. Composite roller bearings reduce friction under load and don’t require lubrication. Load-carrying gears and pins are 17-4PH stainless steel for strength and durability.
