Operating instructions
6. Calculation of crosswind:
Using the graph (plastic card) determine the point of
intersection of the wind speed (head/tailwind compo-
nent) and the crosswind angle.
Going from the point of intersection, read the value
of the crosswind component on the horizontal axis.
Ex. Headwind component: 40 mph
Crosswind angle: 30°
Crosswind component: 20 mph

7. Calculate the angle of drift:
Locate the crosswind component (20) on the exterior
rotating bezel
interior bezel
Ex. Angle of drift: approx. 6.5°
8. Calculation of corrected bearing:
If the wind is blowing from the right, add the angle of
drift to the magnetic bearing.
If the wind is blowing from the left, subtract the angle
of drift from the magnetic bearing.
Ex. Corrected bearing: 40° + 6.5° = 46.5°
For memorization, use the crown
rected bearing (t) on the lower interior rotating bezel
and read the value indicated on the
