ANDERSEN 50ST FS Self-Tailing Manual Winch

Major effect with minor effort

The ANDERSEN 50ST FS Self-Tailing Manual Winch features 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. What's more, the Power Ribprinciple 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.

Low maintenance
Andersen winches require less maintenance, since all pawls and springs are captive, and the design of the winch allows you to strip it down for service and greasing.

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.
