Dodging obstacles in Auto mode
To avoid an obstacle when your boat is under autopilot control:
1. Select a course change in the appropriate direction. For example,
press -10 three times for a 30° dodge to port.
2. When safely clear of the obstacle, you can either:
• reverse the previous course change (for example, press +10
three times), or
• return to the previous locked heading (LAST HDG)
