The ST290 Pilot Keypad has a built in automatic tack facility (AutoTack)
that turns the boat through a preset angle in the required direction. The
default angle is 100º.
If you have set the vessel type to SAIL BOAT, you can adjust the default
AutoTack angle in Pilot Basic or Advanced calibration (see Section 8,
Chapter 5):
• To AutoTack to port:pressthe
-1 and -10 buttons together.
• To AutoTack to starboard:pressthe
+1 and +10 buttons together.
WARNING:
When making major course changes, the trim on the boat may
change substantially. Because of this, the autopilot may take some
time to settle accurately onto the new course.
