ANDERSEN 12 ST FS Self-Tailing Manual Single Speed Winch - Full Stainless

The 12 ST FS Self-Tailing Manual Single Speed Winch in full stainless steel is the perfect addition to any marine vessel, offering exceptional performance and durability for sailors who demand the best. Designed for ease of use and longevity, this winch ensures smooth handling of sails and lines, enhancing your overall sailing experience.

Innovative Power Rib™ Technology

Our Power Rib™ technology sets ANDERSEN winches apart from the competition. Unlike conventional winches that use abrasive drum surfaces, the Power Rib™ features vertical ribs running along the drum’s surface. This unique design, combined with polished stainless steel, provides superior grip on ropes while minimizing wear and tear. The result is longer-lasting sheets and halyards, reducing replacement costs and maintenance efforts.

Moreover, the Power Rib™ enhances sailing maneuvers by requiring fewer turns during tacking, allowing sheets to be eased smoothly without abrupt snatches. This significantly lowers the risk of overridden or jammed sheets, ensuring a more reliable and enjoyable sailing experience. Over time, the ribbed drum maintains its grip consistently, unlike sandpaper-like surfaces that degrade with use.

Optimized Power Ratio for Maximum Efficiency

The Power Ratio of a winch is a crucial factor in determining its mechanical advantage and pulling capacity. It is calculated using the formula:

Power Ratio = (Length of Handle × Gear Ratio) / Radius of Drum

This ratio indicates the winch's ability to handle loads effectively, beyond just its physical size or drum diameter. For example, applying a 10kg load with a 10" standard handle on a winch with a Power Ratio of 40:1 results in a pulling capacity of up to 400kg, assuming 100% efficiency. While real-world conditions may slightly reduce this capacity due to internal friction, the high Power Ratio ensures robust performance even under demanding conditions.
