28 ST FS - 2-Speed Self-Tailing Manual Winch - Full Stainless Steel
Power Rib™
ANDERSEN Winches© feature 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.
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.

Service Kits
Regular maintenance is important for smooth and trouble-free operation of your
winches. ANDERSEN Winch Service Kits use authentic factory replacement parts
and include all the crucial spare parts necessary to ensure perfect
performance from your winch every time.
In normal recreational use, we recommend cleaning, greasing and inspection of
all moving parts every 2 years for extending winch life. Under extensive use,
such as racing, charter or blue water sailing, we recommend more regular
maintenance procedures; at least once every year.
