Harken 50 Self-Tailing Radial Aluminum Winch – 2-Speed – 50.2STA

Take control of your sail handling with the Harken 50.2STA Self-Tailing Radial Aluminum Winch — a robust, precision-engineered 2-speed winch designed to make trimming sheets, halyards, and control lines smoother and more efficient on performance cruisers and racing sailboats. Crafted with a lightweight anodized aluminum body, this winch delivers excellent strength-to-weight performance, corrosion resistance, and long-lasting reliability in demanding offshore and coastal environments.

The 50.2STA’s self-tailing design enables secure one-handed line handling, reducing crew effort and enhancing safety on deck. Switching between two gear ratios gives you the flexibility to crank in heavy loads with mechanical advantage or speed through lighter adjustments — making it ideal for both everyday cruising and competitive sailing.

Designed with radial geometry, this winch promotes optimal line wrap and smooth power transmission. Precision gears, sealed bearings, and quality construction ensure dependable performance and long service life, race after race or voyage after voyage.

Summary for the User

The 50.2STA is the ideal "workhorse" winch for large sailing vessels. It provides a massive 50.4:1 power ratio in second gear to handle heavy sheets and halyards while being significantly easier to carry and install than its chrome counterparts. It is also designed for future flexibility, as it can be converted to electric or hydraulic power if you decide to upgrade your systems later.

Installation Tip: When installing, ensure the drive gear is positioned on the side where the line enters the winch drum. This placement ensures the highest loads are pulled directly against the drive gear for maximum efficiency and longevity.
