Andersen Winches

Enduring Strength,
Everlasting Finish
Every Andersen winch is made with the care and craftsmanship that come
from more than fifty years of experience. Andersen winches are built to last,
to retain their exceptional finish and to deliver season after season of reliable
performance and sailing pleasure to their owner through the years.
Andersen winch drums are produced from grade 316L stainless steel, cold formed in stages
during manufacture to further increase strength and hardness as it takes its final form. The
resulting construction is lightweight, yet stiff and unyielding.
Drive shafts are in grade 329 duplex stainless steel. Pawls are cut from a cold pressed profile
in grade 316 stainless steel and are virtually unbreakable.
The upper centre stems of Andersen winches are manufactured from aluminium bronze for
ultimate durability. The combination of materials and design contribute to a lightweight, rigid
final assembly that enhances the mechanical efficiency of the winch. Andersen winches are
of similar weight to winches with aluminium drums, but are far more durable.
Andersen winch drums incorporate the distinctive Power Rib™ which ensures a controlled
grip on the line at all times, whether trimming or easing. The highly polished stainless steel
surface minimises vertical friction and allows the loaded rope turns to slide easily upward as
the drum rotates, without the shuddering and excessive rope wear seen on winches that rely
on a rough surface finish for grip.
Stainless steel roller bearings and ball bearings carry the highest drum loads to the centre
stem of the winch, minimising efficiency losses due to friction.
The self-tailing arm can be rotated through 360 degrees for optimum positioning (40ST and
larger). Stainless steel self-tailing jaws adjust automatically to suit various rope sizes.
Andersen winches are designed for simple, straightforward installation and maintenance.
Servicing is only required every two years or so under normal use.
