Steering Patterns
WARNING
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 Williamson turns.

the active waypoint and begins the cloverleaf pattern.
You can adjust the distance between the waypoint and
the location where the autopilot turns the boat for another
pass over the waypoint. The default setting turns the boat
at a range of 1000 ft. (300 m) from the active waypoint.
