The Harken 20STA Self-Tailing Radial Winch delivers powerful, efficient sail handling in a compact aluminium design.

The Harken 20 Self-Tailing Radial Winch Aluminum - 20STA is engineered for sailors who demand smooth, reliable sail handling with maximum efficiency and minimal line wear.

This makes the 20STA an ideal solution for shorthanded sailing, racing crews, and cruising sailors looking for dependable performance in a compact footprint.
