Lewmar 50ST EVO® Self Tailing Winch Alloy - Grey
Lewmar 50ST EVO® Self Tailing Winch Alloy - Grey — Product description
Upgrade your sailing experience with the Lewmar 50ST EVO Self-Tailing Winch in sleek alloy grey. Crafted for serious sailors who demand reliability under pressure, this winch builds on decades of Lewmar's marine engineering expertise. Whether you're trimming sails on a coastal cruiser or pushing limits in offshore racing, its intuitive design and robust performance make handling heavy loads feel effortless.
What sets the 50ST EVO apart is its thoughtful evolution from the classic Ocean series. The self-tailing jaws grip lines securely without slippage, even in wet conditions, allowing single-handed operation during those critical maneuvers. The grey alloy finish not only resists corrosion in harsh saltwater environments but also complements modern deck aesthetics for a professional look.
Key Advantages for Everyday Sailing
- Tool-Free Servicing: Pop open the end cap and service the winch in minutes—no special tools needed. This means less downtime at the dock and more time on the water, keeping maintenance simple for weekend warriors and pros alike.
- Clear Direction Arrows: Engraved indicators show exactly how to operate the winch, reducing errors during high-stress moments like a spinnaker takedown in building winds.
- Electric Conversion Ready: Designed with modularity in mind, it seamlessly upgrades to electric for powered sheet handling on larger yachts, future-proofing your setup without a full replacement.
Precision Engineering Meets Power
The two-speed operation shifts smoothly: low gear (2.6:1) for fast line retrieval when easing sheets, and high gear (9:1) for maximum cranking power. With power ratios of 13.9:1 and 48.6:1, it handles loads up to 2756 lbs safely, ideal for 3/8" to 9/16" lines common on boats over 50 feet.

Real-World Performance Tips
For optimal results, pair it with low-stretch Dyneema or polyester lines in the recommended range—thinner lines spin faster in low gear for quick tacks. On bigger boats, position it near the cockpit for easy reach, and rinse with fresh water after every sail to extend its anodized alloy life. Many owners report years of flawless service with minimal upkeep, making it a smart investment for long voyages.
Delivered ready to install with a detailed instruction manual, this winch empowers you to sail smarter, not harder.
