Adjusting the counter rudder
If you intend to use
RESPONSE
level 3 (the tightest possible coursekeeping),
you will need to adjust the counter rudder.
Counter rudder is the amount of rudder the SmartPilot applies to try to prevent the
boat from yawing off course. Higher counter rudder settings result in more rudder
being applied.
To check the counter rudder setting:
1. Set
RESPONSE
to level 3 (see
page 32
)
2. Motor your boat at cruising speed in clear water
3. Press
auto
to switch the SmartPilot to Auto mode, then make a 90° course
change:
• when gain and counter rudder are both set correctly, the boat performs a
smooth continuous turn with minimal overshoot
• if the counter rudder is too low, the boat will still overshoot
• if counter rudder is too high, the boat will ‘fight’ the turn and make a
series of short, sharp turns: this results in a very ‘mechanical’ feel as the
boat changes course
