ANDERSEN RA2012010000 12ST Winch FS Single Speed

Makes sailing more pleasurable

The ANDERSEN RA2012010000 12ST Winch FS 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.
