Harken 15 Self-Tailing Radial Winch Aluminum - 15STA

The Harken 15STA Self-Tailing Radial Winch delivers lightweight, efficient sail handling in a compact aluminium design. Featuring Harken’s proven Radial drum technology and integrated self-tailing mechanism, it provides excellent grip, reduced rope wear, and smooth trimming performance for smaller racing and cruising sailboats.

The Harken 15 Self-Tailing Radial Winch Aluminum - 15STA is engineered to provide reliable sail handling performance in a compact and lightweight package. Built around Harken’s industry-leading Radial drum technology, the drum surface features specially designed diagonal ribs that maximise gripping power while significantly reducing rope wear compared to traditional abrasive drum surfaces.

Its integrated self-tailing mechanism allows one crew member to trim or hoist sails quickly and efficiently without requiring additional manual tailing assistance. This makes the 15STA ideal for shorthanded sailing, club racing, trailer sailers, and smaller keelboats where simple and efficient sail handling is essential.

Constructed from lightweight marine-grade aluminium, the 15STA delivers an excellent balance of strength, corrosion resistance, and reduced overall weight. The compact single-speed design provides smooth trimming performance while maintaining a minimal footprint on deck.

Perfect for sheets, halyards, and control line systems on smaller sailboats, the Harken 15STA offers dependable performance, trusted reliability, and efficient sail control for both racing and cruising sailors.
