Guess your heading relative to the wind and adjust the indicated heading to wind on your SC-1 to
3
that value. 45° is a good starting point for many boats.
Tack and sail close-hauled on the new tack. Adjust your indicated heading to wind to the same
4
value used in step 3.
5
Tack again and take note of your indicated heading to wind on the new tack.
6
Adjust your indicated heading to wind to the average of the angles seen in steps 4 and 5 (i.e. split
the difference). In this example the average would be (45 + 35) / 2 = 40°. Once you have done
this, the reference wind direction stored on the SC-1 will be aligned with the true wind direction.
Please Note: If you begin this process with the reference wind direction stored on the SC-1 closer to
the true wind direction than is illustrated in the above example, you may be able to complete the
calibration with only one tack instead of two, jumping from step 3 directly to step 6.
