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 MENU > 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.
1 From the autopilot screen, select MENU > Pattern Steering > Orbit.
2 Select Engage Port or Engage Starboard.
Setting Up and Following the Cloverleaf Pattern
You can use the cloverleaf pattern to steer the boat to repeatedly pass over an active waypoint. When you begin
the cloverleaf pattern, the autopilot drives the boat toward 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.
1 From the autopilot screen, select MENU > Pattern Steering > Cloverleaf.
2 If necessary, select Length, and select a distance.
3 Select Engage Port or Engage Starboard.
Setting Up and Following a Search Pattern
You can use the search pattern to steer the boat in increasingly larger circles outward from the active waypoint,
forming a spiral pattern. When you begin the search pattern, the autopilot immediately drives the boat in a circle
centered on the active waypoint and expands the spiral as it completes each circle.
You can adjust the distance between each circle in the spiral. The default distance between circles is 50 ft.
(20 m).
1 From the autopilot screen, select MENU > Pattern Steering > Search.
2 If necessary, select Search Spacing, and select a distance.
3 Select Engage Port or Engage Starboard.
Cancelling a Steering Pattern
• Physically steer the boat.
NOTE: Shadow Drive feature must be enabled to cancel a steering pattern by physically steering the boat.
• Select or to cancel a pattern using step steering mode.
• Select Standby.
Adjusting the Autopilot Response
The Response setting allows you to adjust the autopilot responsiveness for varying sea and wind conditions.
For advanced autopilot configuration, see the configuration guide included with your autopilot system.
1 From the autopilot screen, select MENU > Response.
2 Adjust the rudder response.
If you want the rudder to be more responsive and move more quickly, increase the value. If the rudder is too
responsive and moving too quickly, decrease the value.
