This is the tactician's greatest ally in the search for the right wind
shifts. It shows the compass direction of the wind regardless of
the boat's heading or speed. True wind direction is calculated
from the true wind angle and heading, and is corrected for
calibration errors by the true wind look-up table. A full explanation
is given in
Part 3 - Calibration.
