White Label WINDEX 15 Large Bolt-On Wind Vane

Extremely sturdy in all wind conditions

The WINDEX 15 Large Bolt-On Wind Vane is suitable
for family or racing sailing boats with mast heights up to 29 feet
(8.8 meters) to 40-50 feet. Although this is smaller model it
retains the famous and superior Sapphire suspension technology,
which make is 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 meter/second.
(=2/10 knots).

The reference tabs are set at the proper angle to correspond to the
apparent wind direction for starbord 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 pin point. 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.
