Experience effortless sail handling with the Harken 15STA Self-Tailing Radial Aluminum Winch, engineered for efficient performance on deck. This single-speed winch delivers robust power and reliability, making it ideal for trimming sheets on small daysailers, hoisting halyards, and managing control lines on medium-sized boats up to 30 feet (9 meters). Upgrade your vessel's rigging for smoother, more controlled sailing.

• Lightweight Aluminum Drum: Crafted from durable aluminum for exceptional strength while maintaining a lighter weight compared to classic winches.
• Efficient Self-Tailing Mechanism: Allows a single crew member to quickly and easily trim or raise sails, simplifying sail management and freeing up deckhands.
• Radial Drum with Diagonal Ribs: Features a uniquely shaped gripping surface with diagonal ribs that maximize holding power and significantly reduce line wear, preventing overrides and ensuring a smooth, controlled line release.
• Durable Internal Components: Load-carrying gears and pins are constructed from 17-4PH stainless steel for superior strength and long-term durability, even in demanding marine environments.
• Maintenance-Friendly Design: Composite roller bearings reduce friction and do not require lubrication. The snap-fit design keeps bearings captive in a high-strength Delrin® cage, allowing the drum to lift out as a single unit for quick and mistake-free seasonal maintenance.
