Standout Features for Seamless Sailing
- Tool-Free Servicing: Disassemble and maintain with ease—no special tools needed. This keeps downtime minimal during regattas or extended voyages.
- Clear Direction Arrows: Engraved indicators guide your hands instinctively, reducing errors under pressure and speeding up maneuvers.
- Electric Conversion Ready: Future-proof your setup by easily upgrading to powered operation, ideal for larger boats or crews preferring minimal physical effort.

These features combine to deliver a winch that's not just functional but intuitive, enhancing safety and efficiency on deck.
Engineered for Power and Precision
The 50ST EVO boasts a two-speed gear system: a fast 2.6:1 first gear for quick line retrieval and a robust 9:1 second gear for heavy loads. This translates to impressive power ratios of 13.9:1 and 48.6:1, handling sails up to a safe working load of 2756 lbs effortlessly.
- Drum Diameter: 3.66 inches for smooth line wrapping
- Base Diameter: 7.13 inches, fitting standard deck mounts
- Overall Height: 7.75 inches, low-profile for clear visibility
- Line Entry: 3.39 inches, accommodating thicker ropes
- Weight: Just 19.4 lbs, balancing strength with minimal added boat weight
Perfect for genoa sheets, spinnaker halyards, or mainsheet systems on mid-to-large yachts, it excels where torque meets speed.
Why Sailors Choose the 50ST EVO
Beyond specs, this winch shines in real-world use. The black alloy finish not only looks premium against carbon decks but also sheds heat faster in tropical climates. Self-tailing reduces crew fatigue during long tacks, crucial for shorthanded sailing. Compared to older models, EVO's drum texture grips wet lines better, minimizing overrides even in choppy seas.
For racing teams, the quick-release feeder arm allows rapid line changes. Cruisers appreciate the low maintenance, with drum bearings that stay smooth after thousands of cycles. It's a smart investment that boosts your boat's resale value while delivering years of trouble-free service.
Pro Tips for Longevity
Keep your winch performing like new with simple routines: rinse with fresh water after every sail to flush salt, lubricate pawls sparingly with marine grease, and inspect jaws annually. The tool-free design means you can service it at anchor—no hauling tools from the bilge. Pair it with Lewmar's winch handle for optimal leverage, and consider servicing kits for proactive care.
