ANDERSEN 12ST Winch BT Single Speed

Makes sailing more pleasurable

The ANDERSEN 12ST Winch BT Single Speed 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 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.

Low maintenance is a key
With ANDERSEN Winches, you can take it for granted. Our 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.
