3-10-3 Auto tacking or gybing in wind mode
If the set wind angle (SWA) is 90° or less, the boat tacks, if the SWA is more than 90° the boat gybes. After
the tack or gybe, the SWA is the same as the SWA before the tack or gybe, but from the
other side.

Example:
SWA is 40°, so the boat will tack, not gybe. If the tack angle is not set to Auto, the boat changes direction
twice:
- first by the tack angle
- second so that SWA is the same as before the tack or gybe, but on the other side:
After the boat has reached the tack angle, the boat turns again so
that the SWA (set wind angle) is the same as the SWA before the
tack, but from the other side
