Advanced Self-Tailing Performance for Effortless Sailing

The Lewmar 30AST Two-Speed Self-Tailing Aluminum Winch is engineered to provide exceptional rope-handling capabilities for marine applications. Featuring Lewmar’s innovative "Wavespring" self-tailer, this winch ensures a secure yet gentle grip on a variety of rope diameters, from traditional Dacron composite to modern smaller-diameter lines. Its self-adjusting springs optimize performance while the smooth, low-friction feeder arm prevents snags for uninterrupted operation. Designed for efficiency and ease of use, this winch is ideal for sailors looking for reliability in demanding conditions.

Precision Engineering for Maximum Efficiency

The two-speed functionality allows for efficient power transfer, making line handling smooth and effortless. The first gear enables rapid line retrieval, while the second gear provides increased mechanical advantage for handling high loads with ease.
