ANDERSEN 18 ST FS RA2018010000 Full Stainless Self-Tailing Manual Single-Speed Winch

18 ST FS Self-Tailing Manual Single Speed Winch - Full Stainless

Power Rib

ANDERSEN Winches feature the Power Rib. Unlike other winches with abrasive drum surfaces, ANDERSEN winch drums have vertical ribs running up the surface. This combined with the smooth polished stainless steel gives a maximum grip and minimum wear on ropes, reducing the replacements costs of sheets and halyards. Whats more, the Power Rib principle simply makes sailing more pleasurable. Fewer turns on the winch make tacking easier. Sheets can be gently eased out without harsh snatching and the risks of overrides and jammed sheets are significantly reduced. The grip provided by the ribs will remain the same year after year, unlike many other winches with an abrasive or sandpaper-like surface. Such surfaces have a tendency to wear down both ropes and themselves.

Power Ratio

Power Ratio is the mechanical advantage of the winch and is calculated as follows:

length of handle x gear ratio
radius of drum

The pull of the winch is based on the Power Ratio and not just on the physical size of the winch or the diameter of the drum. The Power Ratio is used to determine the load the winch may handle as follows: pull of handle (kg x Power Ratio = pull of winch (kg).

This means that by applying a load of 10kg, using a 10" standard handle, on a Power Ratio 40:1 winch, the winch can pull 400kg, assuming that the winch is 100% efficient. This is not possible in practice as the efficiency is reduced by internal mechanical friction losses.

The ANDERSEN 18 ST FS Self-Tailing Manual Single-Speed Winch is a full stainless steel sailing winch designed for sailors who want dependable sheet and halyard control with reduced rope wear. Its polished stainless steel drum and Power Rib surface provide consistent grip while helping make trimming, easing, and tacking more controlled and manageable.

ANDERSEN Power Rib technology uses vertical ribs on the winch drum instead of an abrasive surface. The ribbed design grips lines effectively while minimizing the wear that abrasive or sandpaper-like drums can cause to ropes and to the drum itself. Consistent rope engagement can help reduce the number of turns required, support smoother sail handling, and reduce the risk of overrides and jammed lines during use.

This manual, single-speed winch is self-tailing, making it suited for sailboat applications where efficient line handling is important. The 18.8:1 first-speed Power Ratio provides mechanical advantage based on the handle length, gear ratio, and drum radius. Actual pulling force depends on applied handle load and mechanical efficiency, so the Power Ratio should be used as a reference when evaluating winch operation and load handling.
