Northstar NS3300 Pilot
There are four possibilities for auto tacking or gybing: 
Tack (SWA is 90° or less) 
Gybe (SWA is more than 90°)
An error message is displayed if you attempt other tacks or if the tack will end 
with the boat in irons.
Note: To view or change the tack mode, tack angle, gybe mode, gybe angle or 
tack delay, go to the Options menu (see section 6-3).
Example:
 SWA is 120°, so the boat will gybe. 
The tack angle is not set to AUTO:
Example:
 SWA is 40°. The tack angle is set to AUTO so the boat 
changes direction once:
