Harken 40 Self-Tailing Radial Winch — 2 Speed Aluminum - 40.2STA

Harken 40 Self-Tailing Radial Winch — 2 Speed Aluminum - 40.2STA

The Harken 40.2STA Self-Tailing Radial Winch combines lightweight aluminium construction with powerful two-speed performance for smooth, efficient sail handling. Featuring Harken’s proven Radial drum technology and integrated self-tailing system, it delivers exceptional grip, reduced rope wear, and reliable trimming performance for racing and cruising yachts.

The Harken 40 Self-Tailing Radial Winch — 2 Speed Aluminum - 40.2STA is engineered to provide efficient sail handling performance with reduced weight and outstanding durability. Built around Harken’s renowned Radial drum technology, the drum surface uses specially shaped diagonal ribs rather than abrasive textures, maximising rope grip while significantly reducing line wear for longer rope life and smoother operation.

The integrated self-tailing mechanism allows a single crew member to trim or hoist sails quickly and efficiently without needing manual tailing assistance. Combined with the two-speed gearing system, sailors can easily switch between fast line retrieval and increased mechanical advantage under higher loads, improving control and reducing fatigue during manoeuvres.

Constructed from lightweight marine-grade aluminium, the 40.2STA offers an ideal balance of strength, corrosion resistance, and reduced overall weight compared to chrome alternatives. Its efficient power ratios make it suitable for handling sheets, halyards, and trimming systems on performance yachts and cruising boats alike.

Compatible with both manual and electric power configurations, the 40.2STA provides flexibility for a wide range of sailing applications. Whether racing competitively or cruising offshore, this winch delivers smooth, dependable performance with trusted Harken engineering.
