Lewmar 40ST EVO® Self Tailing Winch Alloy - Black — Product description

Discover Superior Control on the Water

Upgrade your sail-handling experience with the Lewmar 40ST EVO Self-Tailing Winch in sleek black alloy. Designed for serious sailors who demand precision and reliability, this winch transforms the way you manage sheets and halyards under demanding conditions. Whether you're racing in high winds or cruising long distances, its two-speed operation delivers effortless power, letting you focus on the horizon rather than the grind.

Crafted from lightweight yet durable alloy with a premium black anodized finish, it resists corrosion in harsh marine environments while adding a modern aesthetic to your deck. Sailors rave about its smooth action and intuitive design, making it a staple on performance yachts and bluewater cruisers alike.

Standout Features for Everyday Excellence

  • Tool-Free Servicing: Disassemble and maintain without specialized tools, saving time during routine upkeep or mid-season overhauls. A game-changer for solo sailors or those far from shore support.
  • Intuitive Direction Arrows: Clear markings guide your hand naturally, reducing errors during high-stress maneuvers like tacking or gybing.
  • Electric Conversion Ready: Future-proof your setup with straightforward upgrades to powered operation, ideal for larger boats or crews seeking efficiency boosts.
  • Self-Tailing Jaws: Automatically grip ropes from 8mm to 13mm, allowing single-handed operation without slippage—even with wet or frozen lines.
  • Ergonomic Drum Grip: Cross-hatch pattern ensures secure hold, minimizing hand fatigue on long hauls.

Precision Engineering: Key Specifications

Built to handle real-world loads with unmatched efficiency, here's what sets this winch apart technically:

Specification Measurement
Drum Diameter 2.91"
Base Diameter 5.83"
Height 6.24"
Line Entry Angle 3.11"
Suitable Line Size 0.32" - 0.5" (8-13mm)
Gear Ratios 1st: 1.9:1 | 2nd: 5.8:1
Power Ratios 1st: 13.2:1 | 2nd: 40.2:1
Safe Working Load (SWL) 1753 lbs

The compact footprint fits seamlessly on rails or decks, while the impressive power ratio in second gear cranks in heavy loads with minimal effort—perfect for spinnaker sheets or large genoas.

Real-World Performance and Tips

In practice, the 40ST EVO shines during short-handed sailing. The first gear handles fast line retrieval for quick adjustments, while second gear tackles the heavy lifting. Its black alloy body not only looks sharp but sheds heat efficiently during prolonged use in tropical climates.

Installation Insight: Bolt directly to standard deck patterns; use marine-grade sealant for a watertight seal. Pair with Lewmar's matching handles for optimal torque.

Maintenance Mastery: Rinse with fresh water after every sail, especially in saltwater. Annual grease checks on the pawl system keep it spinning like new—tool-free access makes this a 10-minute job.

Compared to older models, the EVO's redesigned feeder arm prevents line jams, boosting reliability when seconds count in regattas.
