White Label WINDEX 10 Medium Bolt-On Wind Vane

Extremely sturdy in all wind conditions

The WINDEX 10 Medium Bolt-On Wind Vane is suitable
for family or racing sailing boats with mast heights up to 8-9
meters (25-30 feet). Although this is smaller model it retains the
famous and superior Sapphire suspension technology, which make it
possible to recognize changes in the wind direction as small as one
degree. Like all WINDEX models it is extremely sturdy in all wind
conditions and it has been wind tunnel tested in speeds up to 80
knots!

WINDEX consists of a moving vane and two fixed reference tabs. The
balanced vane has low inertia, large fin area and low-friction
suspension sapphire. These qualities make the Windex respond
quickly and accurately at wind speeds as low as 0.1 metre/second.
(=2/10 knots).

The reference tabs are set at the proper angle to correspond to the
apparent wind direction for starboard and port tacking. The
reference tabs make it easy to read the relative wind direction as
accurately as plus or minus 1 degrees under tacking conditions,
where precise information is essential for optimum performance.

The suspension consists of a sapphire bearing rotating on a
stainless steel pinpoint. The front and rear end of the vane and
the two reference tabs are light reflecting for good visibility
during night sailing.

WINDEX is tested in wind tunnels at speeds up to 80 knots and has
proved its mechanical ruggedness on a large number of successful
ocean racers during many years.
