wind calibration
Wind calibration sets the wind speed units, damping, and masthead unit offset. The masthead unit offset can be
adjusted while observing the live apparent wind angle on the same page.
MHU Offset is calculated by the following procedure:-
1. Sail close-hauled on a Port Tack, note the set of all sails. When conditions are steady note the AWA e.g. Port
35
°
.
2. Tack the boat until close-hauled on a Starboard Tack, ensure the sails are set as for the Port Tack. When
conditions are steady note the AWA e.g. Starboard 25
°
.
3. To calculate the Offset subtract the Starboard value from the Port value, then divide by two. e.g. Port 35
°
-
Starboard 25
°
= 10 / 2 = 5.
If the value is positive the offset is to Port, if the value is negative it is to Starboard.
