Lightweight Power with Precision Grip

Whether you're trimming sails on a coastal cruiser or managing halyards on a performance yacht, the Harken Aluminum Self-Tailing Radial Winch offers a perfect blend of strength, efficiency, and ease of use. Designed for sailors who demand reliable sail handling with minimal maintenance, these winches are a go-to choice for both new installations and upgrades.

Key Features

• Radial Drum Design The winch drum features diagonal ribs shaped specifically for aluminum to maximize grip while minimizing line wear. Unlike abrasive surfaces, these ribs hold the line securely without damaging modern rope fibers.
• Self-Tailing Mechanism The integrated self-tailer allows one person to trim or hoist sails with ease. The adjustable upper jaw adapts to different line diameters and maintains a firm hold under varying loads.
• Lightweight Aluminum Construction Compared to bronze or chrome models, aluminum winches offer significant weight savings—ideal for performance-oriented rigs or reducing weight aloft.
• Smooth Easing Under Load Patented rib geometry drives line wraps downward during easing, keeping them in the zone of maximum control and preventing overrides.

• Maintenance-Friendly Design With composite roller bearings, snap-off skirts, and a modular layout, these winches are easy to install and service—no need to remove the drum for deck mounting.

1-Speed vs. 2-Speed Models

The 1-speed models are ideal for halyards and control lines on smaller boats, while 2-speed winches offer the versatility needed for genoa sheets, mainsail trimming, and heavier applications.
