12 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.

ANDERSEN 12 ST FS Self-Tailing Manual Single-Speed Winch is designed for sailors who want dependable manual line handling with the lasting grip of a full stainless steel winch. Model RA2012010000 combines ANDERSEN Power Rib technology with self-tailing operation to help manage sheets and halyards more smoothly during everyday sailing and sail adjustments.
The Power Rib drum uses vertical ribs and a smooth polished stainless steel surface to provide strong rope grip while minimizing abrasion compared with abrasive drum surfaces. This design helps reduce rope wear and supports consistent handling over time. The ribbed drum also requires fewer turns for operation, helping make tacking easier while allowing sheets to be eased out more gently with reduced risk of overrides and jammed sheets.
With a manual single-speed configuration, this ANDERSEN winch provides straightforward control for sailors who prefer a traditional, hands-on setup. Its 1st-speed gear ratio is 1.3:1, while the 1st-speed power ratio is 9.5:1. Power ratio describes the mechanical advantage created by the winch and handle, helping users understand how applied handle force is multiplied through the winch mechanism. Actual pulling performance depends on mechanical efficiency and friction losses.
