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.
Following the U-Turn Pattern
You can use the u-turn pattern to turn the boat around 180 degrees and maintain the new heading.
1 From the autopilot screen, select Options > Pattern Steering > U-Turn.
2 Select Engage Port or Engage Starboard.
Setting Up and Following the Circles Pattern
You can use the circles pattern to steer the boat in a continuous circle, in a specified direction, and at a
specified time interval.
1 From the autopilot screen, select Options > Pattern Steering > Circles.
2 If necessary, select Time, and select a time for the autopilot to steer one complete circle.
3 Select Engage Port or Engage Starboard.
Setting Up and Following the Zigzag Pattern
You can use the zigzag pattern to steer the boat from port to starboard and back, over a specified time and
angle, across your present heading.
1 From the autopilot screen, select Options > Pattern Steering > Zigzag.
2 If necessary, select Amplitude, and select a degree.
3 If necessary, select Period, and select a length of time.
4 Select Engage Zigzag.
Following the Williamson Turn Pattern
You can use the Williamson turn pattern to steer the boat around with the intent of running alongside the
location where the Williamson turn pattern was initiated. The Williamson turn pattern can be used in man
overboard situations.
1 From the autopilot screen, select Options > Pattern Steering > Williamson Turn.
2 Select Engage Port or Engage Starboard.
Following an Orbit Pattern
You can use the orbit pattern to steer the boat in a continuous circle around the active waypoint. The size of the
circle is defined by your distance from the active waypoint when you begin the orbit pattern.

2 Select Engage Port or Engage Starboard.
