5 Commissioning the Autopilot
2. Sail your boat at cruising speed in clear water:
• you will find it easiest to recognize the steering response in
calm sea conditions where wave action does not mask basic
steering performance
3. Press
AUTO to enter Auto mode, then alter course by 40°:
• if the rudder gain is adjusted correctly, the 40° course change
should result in a crisp turn followed by an overshoot of no
more than 5°
• if the rudder gain setting is too high, the 40° course change
will result in a distinct overshoot of more than 5° and there
may be a distinct ‘S’ in the course (
A)
Correct this oversteer by reducing the rudder gain setting.
• if the rudder gain is too low, the boat’s performance will be
sluggish – it will take a long time to make the 40° turn and
there will be no overshoot (B)
Correct this understeer by increasing the rudder gain setting.
To adjust the default rudder gain:
1. Access the Rudder Gain screen in Calibration mode.
2. Use the
▲ (NAV) and ▼ (LIGHTS) keys or course change knob to
adjust the rudder gain as necessary.
3. Press and hold
STBY for 2 seconds to save the changes.
4. Press
AUTO to check the autopilot performance in Auto mode.
