Why Sailors Choose the 50ST EVO for Peak Performance
Handling a spinnaker sheet in 25 knots? The 48.6:1 second-gear power ratio gives you the mechanical advantage to trim without strain. Racers appreciate the fast first gear for rapid adjustments during mark roundings, while cruisers value the durable alloy-chrome plating that shrugs off UV and spray.
Compared to older models, the EVO's redesigned drum and jaws reduce rope chafe and improve line flow, extending the life of your running rigging. It's not just hardware; it's an investment in safer, more enjoyable sails.
Simple Installation and Maintenance Tips
Mounting is straightforward: Match the 7.13" base to your existing winch pattern or drill new holes. Secure with marine-grade fasteners, and you're set. For upkeep, rinse with fresh water after every outing, then tool-free service every 6-12 months—lubricate gears with winch grease for buttery-smooth action.
- Pro Tip: Pair with low-stretch Dyneema halyards for optimal self-tailing grip.
- Upgrade Path: Convert to electric for one-person spinnaker hoists on solo adventures.
