G-PILOT 3100 Operation Manual NAVMAN 29
Problem: drifts off course to one side
Increase trim gain.
Problem: boat moves too far off course closely before the rudder turns to correct
Decrease counter rudder gain.
Decrease trim gain.
This causes wear on the steering linkage and
Reduce counter rudder gain.
Problem: rudder turns too frequently
To simplify changing the parameters when conditions change, the G-PILOT stores ﬁ ve sets of the
steering parameters. Each set is called a proﬁ le and the proﬁ les are numbered 1 to 5. To select a
proﬁ le to use, go to PROFILE in the MAIN menu (see section 3-7).
1 When the G-PILOT is installed, the steering parameters in all the proﬁ les are set to their
2 Select proﬁ le 1 and adjust the steering parameters for optimum steering in typical conditions
(see section 7-3).
3 If the conditions change and the steering is no longer optimum, select another proﬁ le and adjust the
steering parameters again. Repeat this step as required to adjust the parameters in each proﬁ le.
4 When using the G-PILOT to steer, select a proﬁ le suitable for the current conditions. For
example different proﬁ les can be conﬁ gured for rough conditions and calm conditions.
7-3 Adjusting the steering parameters
Problem: oscillations from side to side build up
Problem: after a large course change, boat overshoots and oscillates before
settling to new course
Increase counter rudder gain
