Harken 20 Self-Tailing Radial Winch Chrome - 20STC

The Harken 20STC Self-Tailing Radial Winch combines compact size, premium chrome construction, and efficient single-speed sail handling performance. Featuring Harken’s proven Radial drum technology and integrated self-tailing system, it delivers excellent grip, reduced rope wear, and dependable trimming control for racing and cruising sailboats.

The Harken 20 Self-Tailing Radial Winch Chrome - 20STC is engineered to provide smooth, efficient sail handling in a compact and durable package. Designed around Harken’s renowned Radial drum technology, the drum surface features carefully shaped diagonal ribs instead of abrasive textures, maximising gripping power while significantly reducing rope wear for smoother operation and longer rope life.

Its integrated self-tailing mechanism allows a single crew member to trim or hoist sails quickly and efficiently without requiring constant tailing assistance. This makes the 20STC an ideal solution for shorthanded sailing, club racing, and performance cruising where reliable sail handling is essential.

Constructed with a premium chrome finish, the 20STC offers exceptional durability, corrosion resistance, and a refined appearance suited to modern yachts and performance sailboats. The compact single-speed design provides smooth and controlled trimming performance while maintaining a lightweight and space-efficient footprint.
