Lewmar 30ST EVO 2 Speed Self-Tailing Winch, Size 30, Grey Alloy

The Lewmar 30ST EVO (part number 49530057) is a size 30 self-tailing sailboat winch built for trimming sails with less effort and no special tools. It is the next generation of the Lewmar Ocean Winch design: Lewmar redesigned the winch so the top simply unscrews to lift off the drum and expose the gear train, with every internal component shaped to fit back together only one correct way, so servicing and maintenance stay simple for the boat owner.

The winch runs a 2:1 gear ratio with a 15.8:1 power ratio, giving sailors mechanical advantage when grinding in a loaded sheet. It has a gray anodized alloy drum with a 4-3/4 inch base diameter and stands 4-11/16 inches tall. A stainless steel top-mounted feeder arm keeps the line from riding up and trapping above the jaws, while wave spring jaws automatically adjust to different line diameters so the self-tailing action stays taut. Directional arrows are marked on the winch to show correct rotation, which helps less experienced crew keep the sail trimmed correctly.

This winch is built from stainless steel hardware and alloy castings for marine durability and is backed by a 3 year manufacturer warranty. It is intended for sailboat deck hardware applications where a self-tailing, tool-free winch is needed.
