Harken Radial 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.

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 ribs on chrome winches are spaced closer together than on the aluminium winches to increase friction as the chrome finish is more slippery. This optimizes your grip for trimming as well as for easing the sail in a smooth, controlled manner.

Size 15 and 20 winches use composite bushings to handle high loads in a small package.

Product Information

Harken Radial Winch Features

Maximum holding power with minimum line wear

  • Nonabrasive diagonal ribs on gripping surface hold line securely and reduce line wear; ribs shaped for each winch size and drum material.

Smooth, controlled easing

  • Patented angle of ribs drives line wraps down when easing to keep them on area of drum that provides best control.

High-strength, lightweight

  • Weight savings of 25 to 50 percent compared to Harken Classic winch line.
  • 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.

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.
  • Shaped to smoothly feed line in and out of self-tailing jaws.

Power-grip jaws shaped for easy line entry, optimum hold

  • Upper jaw adjusts under line pressure; accepts a variety of line sizes.
  • Teeth grip evenly with or without load.

Simple to install, easy maintenance

  • Patented mounting system for fast, one-person installation without removing drum.
    1. Snap off the skirt at the base of the winch.
    2. Slide bolts through the slots in the winch base and snap the plastic skirt back on.
    3. Place the stud bolts into the predrilled holes on the deck and tighten from belowdeck.
  • Snap-fit design keeps bearings captive when drum is removed for maintenance.
  • Easy to disassemble for service on deck; socket, washer, and screw-top snap-fit together for mistake-free reassembly.
  • Composite roller bearings don’t require lubrication.
