Experience effortless sail handling with the Lewmar 40CST Two-Speed Self-Tailing Chrome Winch, a powerhouse designed for serious cruisers and racers alike. This winch stands out in the demanding world of marine deck hardware thanks to its innovative Wavespring self-tailer jaws. Unlike traditional self-tailers that can crush delicate modern ropes, the Wavespring technology delivers a gentle yet secure wave-shaped grip, adapting seamlessly to thinner Dyneema composites or thicker Dacron lines. Paired with a low-friction feeder arm, it ensures smooth, jam-free rope entry—even under high loads during tacks or gybes.

Superior Two-Speed Performance for Every Maneuver

The dual-gear system shines in versatility: drop into first gear for lightning-fast line retrieval when easing sheets, then shift to second gear for muscle when cranking in a loaded genoa. This setup multiplies your hand power dramatically, making it ideal for short-handed sailing or when battling choppy conditions. The chrome bronze finish not only resists saltwater corrosion but also minimizes drag, keeping operations buttery smooth over countless seasons.

Engineered for Reliability and Ease

• Self-Adjusting Jaws: Automatically conforms to rope diameters from 8mm to 13mm (5/16" to 1/2"), eliminating slippage on mixed fleets.
• Snag-Free Design: Precision-machined feeder arm guides lines flawlessly, reducing wear and frustration during high-pressure moments.
• Durability in Harsh Environments: Built with marine-grade materials that withstand UV exposure, salt spray, and constant flexing—proven on bluewater passages worldwide.
• Compact Yet Powerful: Balances strength with a footprint that fits standard deck layouts without overwhelming smaller cockpits.

Pro Installation Tips from Deck Pros

Secure mounting is key to longevity. Use five M6 (1/4 inch) countersunk head screws on a 121mm (4 3/4 inch) PCD bolt circle. For optimal performance, angle the rope entry at 5-10 degrees to the winch base—consider a custom base wedge if your deck layout demands it. This prevents binding and extends jaw life. Always bed the base with marine sealant for a watertight seal, and torque fasteners to spec to handle peak loads without flexing.
