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.
