The Harken 50.2 Self-Tailing Radial Winch 2 Speed is engineered for confident single-handed sail handling without compromising performance. Crafted from durable aluminum and designed with a radial drum, this winch delivers precise control where it matters most—on deck, in any breeze. The diagonal rib gripping surface is tailored to the winch size and drum material, delivering superior grip while dramatically reducing line wear over time.

What sets this winch apart is its combination of a self-tailing mechanism and a true two-speed drive. With self-tailing, a single crew member can trim or raise sails quickly and safely, freeing you from constant line handling and letting you focus on steering and sail shape. The two-speed configuration provides the right amount of leverage for big sails and heavy loads, while maintaining fine control for lighter tasks.

Key advantages at a glance

• Diagonal rib grip on the radial drum surface maximizes holding power and minimizes line wear, protecting lines through repeated maneuvers.
• Self-tailing operation enables one-handed trimming and sail raising, improving efficiency and onboard safety.
• Two-speed performance with clearly defined gear and power ratios to match load conditions—from quick, light-tack adjustments to heavy sail hoists.
• Optimized line compatibility supports 8–14 mm lines for versatile halyards and sheets across cruising or racing setups.

Real-world use cases

• Single-handedly trim a mainsail halyard on a broad reach, switching to the higher gear when the sail is fully loaded.
• Raise or reef sails with steady, controlled effort—especially valuable on larger boats where muscle alone isn’t enough.
• Sheet control during short-handed passages or in heavy air, where precise line tension and quick release are critical.
• Seasoned cruisers will appreciate reduced deck clutter and faster sail adjustments during shifts in wind.

Who benefits most

• Cruisers and racers operating with minimal crew or solo sailors who value efficiency and safety.
• Boat sizes where a reliable, lightweight aluminum winch saves weight while delivering durable performance.
• Sailors upgrading from older, non-radial drums or non-self-tailing designs who want easier handling and longer line life.

Tips to maximize performance

• Match line diameter to the recommended 8–14 mm range for optimum grip and wear characteristics.
• Regularly inspect the diagonal rib surface for embedded debris; a clean drum maintains the strongest grip.
• When transitioning from low to high gear, smoothly apply tension to avoid abrupt loads that could stress fittings.
• Keep mounting hardware torque-tight and periodically check fastener integrity to sustain long-term reliability.
