2.14.2.2 True Wind Speed table
Even when placed one meter above the mast head on top of a carbon arm the wind
sensor will measure a flow altered by the effects of the mainsail. When sailing
downwind the mainsail causes an acceleration of the air flow at the mast head and
when the boat is heeling the measurement of the wind will be altered. A calibration of
the wind speed is required for all these reasons.
Procedure for measurement:
Hold the boat upwind at no boat speed and measure the average wind speed shown
by the display. Then, while sailing at all wind angles log the wind speed shown on the
displays. The average values can be used in the correction table. Always think about
logging these values whenever you sail between 5 and 30 knots.
The column on the left indicates the true wind speed in knots, the “V1” column is the
correction to apply in degrees and the “A1” column indicates on which angle the
correction will apply. The same pattern applies for “V2” and “A2” for sidewind and
“V3” “A3” for downwind.
Select the value to be corrected. Modify the value.
