Lewmar Ocean Series 49016000 Self-Tailing Sailboat Winch, Size 16 Single Speed, Aluminum Drum

The Lewmar Ocean Series 49016000 is a Size 16 single-speed, self-tailing sailboat winch built for sailors who need reliable, low-friction sail trimming whether racing or cruising. Its self-tailing feeder arm grips and releases line automatically as you crank, so the sailor can trim without needing a second set of hands to tail the line. The winch has a gray anodized aluminum alloy drum, chosen for its combination of light weight and corrosion resistance in a marine environment. Beneath the drum, a one-piece bronze center stem supports stainless steel main shafts and gear spindles for long-term strength under load, while the internal gear train uses high-tensile bronze gears that are machine-cut to close tolerances for smooth, consistent power delivery. A wave-spring feature with self-adjusting springs lets the winch grip smaller-diameter rope without needing separate spring kits. The winch has a 2:1 gear ratio and a 15.8:1 power ratio, giving mechanical advantage suited to genoa, jib, and other sail-trimming loads on boats sized for a 16-series winch. Servicing is straightforward: the winch uses a screw-on cap and strip-from-the-top construction, so internal components can be removed for cleaning and lubrication without unbolting the winch from the deck and without special tools. The unit measures 4-3/4 inches base diameter and 5-3/4 inches tall, and ships as a single winch with drum.
