3. Press AUTO to switch the autopilot to Auto mode, then make a
90° course change:
• When rudder gain and counter rudder are both set correctly,
the vessel performs a smooth continuous turn with minimal
overshoot.
• If the counter rudder is too low, the vessel will still overshoot.
• If counter rudder is too high, the vessel will ‘fight’ the turn and
make a series of short, sharp turns. This results in a very
‘mechanical’ feel as the vessel changes course.
If necessary, adjust the counter rudder.
Rudder damping
If the autopilot is ‘hunting’, i.e. continuously moving the steering
backwards and forwards by small amounts, increase the rudder
damping setting.
AutoTrim settings
AutoTrim determines how quickly the autopilot applies ‘standing
helm’ to correct for trim changes, caused, for example, by changes
in the wind load on the superstructure, or an imbalance of engines.
Increasing the AutoTrim level reduces the time the autopilot takes
to return to the correct course, but makes the vessel less stable.
If the autopilot:
• Gives unstable course keeping and the vessel ‘snakes’ around
the desired course, decrease the AutoTrim level.
• Hangs off course for excessive periods of time, increase the
AutoTrim level.
