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.

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. Plain-top winches are best handled by two crew—one to trim and one to tail the line.

Harken Performa winches combine the high efficiency of the Radial line with the sandblasted grip of Harken carbon-fiber racing winches for powerful hybrids. Optimized to handle the high-strength line used on sportboats and performance cruisers, Performa winches are a great solution for crews who don’t wish to invest in carbon winches or who need racing winches in smaller sizes.  Power-grip jaws shaped for easy line entry, optimum hold Narrow composite jaws ensure superior holding power on small-diameter, high-strength line Lower jaw adjusts under line pressure; accepts a variety of line sizes. Simple to install, easy maintenance Stud mounting bolts allow fast installation.  Adjustable stripper arm integrated into winch top for safer operation Stripper arm completely covers rotating winch top, preventing fingers and clothing from catching in moving parts. Adjusts to multiple positions after the winch is mounted to optimize line exit. Maximum holding power for high-tech line Sandblasted drums and ribs optimized for halyard and sheeting applications using small-diameter, high-strength line.  High-strength, lightweight High-strength composite roller and ball thrust bearings reduce friction under load. Load-carrying gears and pins are 17-4 PH stainless steel for strength, corrosion resistance.

Electric Radial winches let you relax in luxury and trim any size sail with the push of a button. 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. 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 the central drive shaft and drive through winch gears for a two-speed mechanical advantage. Low-power first gear for fast trimming; higher-power second gear for fine-tuning loaded sheets. An efficient design allows a smaller motor size. Each electric winch requires one control box, one circuit breaker, and two analog switches or one Digital System Switch. All new electric Radial and Performa electric winches are supplied with the appropriate dual-function control box. For replacement or retrofit control boxes, please Get in Touch.

Harken 500 UniPower Radial Aluminum Winch — 12V w/Dual Function Control Box The UniPower is a single-speed winch that combines the advantages of a low-profile manual winch with the power of a 12-, 24-, or 48-volt, low-amp-draw motor. What makes it unique is that the motor is partially embedded inside the drum, so that it extends only 105 mm (4 1/8") below the winch base—a critical feature for small boats where space under the cabin top is limited. Upgrade your sailing experience with the Harken 500 Electric Unipower Radial Aluminum Winch. Engineered for compact spaces, this single-speed, self-tailing winch features a powerful embedded motor and lightweight aluminum construction. With a maximum pulling load of 500 kg and compatibility with line diameters ranging from 8 to 14 mm, it's ideal for small boats that require high performance without compromising space. Designed for durability and ease of use, this winch is a reliable choice for modern sailors.
