Alarm system | 83
Autotrim
standard value is 40 seconds which should
work well on most boats.
Rule of thumb: Set to same value (seconds) as the boat’s
length in feet.
On boats operating on VRF it should be set to 20
seconds.
Rate Limit should be kept at 6.0°/second unless there is
a need for more rapid response in turns.
Minimum rudder
Some boats may have a tendency of not responding to
small rudder commands around the “course keeping”
position because of a small rudder, a rudder deadband,
whirls/disturbance of the water-stream passing the
rudder or it is a single nozzle water jet boat.
Turning the Minimum Rudder function ‘On’, may improve
the course keeping performance on some boats, but will
increase the rudder activity.
New course
Counter rudder setting too low,
overshoot response
Correct setting of counter rudder,
ideal response
New course
Counter rudder setting too high, sluggish
and creeping response
New course
