steering Patterns
‹ CaUTIOn
You are responsible for the safe operation of your boat. Do not begin a
pattern until you are certain that the water is clear of obstacles.
The autopilot can steer the boat in preset patterns for fishing, and it can
also perform other specialty maneuvers such as U-turns and man-overboard
retrieval. You can use the GHC 10 to begin pattern steering.
Pattern steering is not based on GPS, and it can be used without a GPS
device connected to the autopilot.
Zigzag Pattern
The zigzag pattern steers the boat from port to starboard and back, over a
specified time and angle, across your current heading.
