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.

The ANDERSEN 12 ST FS Self-Tailing Manual Single Speed Winch is designed for reliable and efficient handling of sailing lines. Crafted entirely from polished stainless steel, this winch features the innovative Power Rib surface, which enhances grip while minimizing rope wear. Unlike abrasive drum surfaces, the vertical ribs on the drum maintain their grip over time, reducing the need for frequent replacement of sheets and halyards. The smooth operation provided by the Power Rib design makes sailing more comfortable by allowing fewer turns during tacking and easing sheets gently without harsh snatching, thus lowering the risk of overrides and jams. This durability and ease of use make the winch ideal for demanding marine environments and long-term use. The robust construction combined with the stainless steel finish ensures corrosion resistance, providing a long-lasting solution for sail handling needs. The winch's compact dimensions and manageable weight further enhance its suitability for various boat sizes and configurations. The 12 ST FS's gear ratio of 1.3:1 and power ratio of 9.5:1 deliver significant mechanical advantage, enabling easy hauling of heavy loads with minimal effort. The handle length and gear ratio are optimized to provide maximum leverage, making it a practical choice for both casual sailors and seasoned professionals. Designed with precision and built for endurance, this winch is a dependable addition to any sailboat's deck equipment, ensuring smooth and secure line control in all conditions.
