Lewmar 30CST Two Speed Self Tailing Chrome Winch

Discover the Power and Precision of the Lewmar 30CST Winch

Imagine effortlessly managing heavy loads under full sail, with a winch that grips your lines securely yet releases them smoothly every time. The Lewmar 30CST two-speed self-tailing chrome winch delivers that reliability, blending cutting-edge Wavespring technology with a design built for demanding marine environments. Sailors trust it for its ability to tame everything from sleek modern Dyneema lines to classic Dacron halyards, making it a staple on racing yachts and cruising boats alike.

What sets this winch apart? Its self-adjusting jaws conform to varying line diameters without constant tweaking, while the low-friction feeder arm guides rope straight onto the drum—eliminating jams even in rough seas. Whether you're trimming mainsails or hoisting spinnakers, the dual-speed mechanism shifts seamlessly: first gear for quick handling, second for muscle when it counts.

Standout Features for Seamless Sailing

• Wavespring Self-Tailer: Gentle wave-pattern jaws provide superior grip on 8-13mm (5/16-1/2 inch) lines, adapting automatically to prevent slippage or damage.
• Two-Speed Operation: 2:1 first gear zips lines in fast; 4.2:1 second gear multiplies power for tough pulls—perfect for short-handed crews.
• Chrome Finish: Mirror-polished for corrosion resistance and a premium look that withstands salt spray and UV exposure.
• Snag-Free Design: Streamlined feeder arm ensures flawless line entry, reducing wear and frustration during high-stress maneuvers.
• Compact Yet Robust: At just 12.3 lbs, it punches above its weight without overwhelming your deck layout.

These elements combine to make sheet handling intuitive, boosting your confidence on the water. Racers love the speed, cruisers appreciate the durability—it's versatile for boats from 40-50 feet.

Technical Specifications at a Glance

Effortless Installation for Lasting Performance

Mounting is straightforward with five M6 (1/4-inch) countersunk head screws on a 113mm (4 7/16-inch) PCD bolt circle. For optimal function, position the winch so rope enters the drum at a 5-10° angle relative to the base—consider a custom base wedge if your deck angle demands it. This setup minimizes twist and maximizes efficiency, ensuring years of smooth operation.

Pro tip: Pair it with Lewmar's matching handles for the best torque transfer, and always bed the base with marine sealant to fend off leaks.

Real-World Performance and Maintenance Insights

On the water, the 30CST shines in variable conditions. Its power ratio delivers 29.2:1 in high gear, letting solo sailors crank in a loaded genoa without strain. The chrome plating shrugs off harsh marine climates, but regular care keeps it peak: rinse with fresh water after every sail, lubricate the jaws sparingly with winch grease, and inspect springs annually.

Avoid over-tightening lines in low gear to prevent jaw overload—shift up for power pulls. With proper upkeep, this winch becomes a deck fixture for a decade or more.
