WIND SENSOR MISALIGNMENT CORRECTION
For accurate wind angle readings the wind sensor should be
pointing forward and aligned with the centreline of the boat.
However, this is not always possible, so Network WIND
allows a wind sensor offset value to be entered to
compensate for the misalignment electronically.
Firstly the amount of misalignment must be found. The
following procedure will enable you, during the course of a
sea trial, to establish the value.
1 Sail close-hauled on a Port Tack, note the set of all the
sails.
When the conditions are steady, note the apparent wind
angle (AWA) on the analogue display, e.g. Port 35
0
.
NOTE : If you have Network TACK or Network DATA the
AWA can also be read from these.
2 Turn the boat until close-hauled on a Starboard Tack,
make sure the sails are set as for the Port Tack.
When the conditions are steady, note the AWA on this
tack, e.g. 25
0
.
3 Determine the direction of the misalignment and wind
sensor offset value by subtracting the Starboard value
from the Port value, then dividing by two.
e.g. Port 35 - Starboard 25 = 10
÷
2 = 5.
If the value is positive the misalignment is to Port, if the
value is negative it is to Starboard.
4 Enter the wind sensor offset value into the Network
WIND unit's memory by following the procedure below.
5 The alignment procedure should be repeated until the
displayed AWA is equal on both tacks.
