Nav Gain
The Navigation Gain determines how many degrees the
autopilot must change the vessel's heading in order to bring the
vessel back on track using the Cross Track Error and the
vessel's speed.
The higher the value of the Nav Gain, the greater the correction.
If the value is set too low, the vessel may use a long time to
reach the track. It can also drift away at strong side current.
Too high value will cause the vessel to overshoot or oscillate
around the track.
The default setting depends on the boat length and the range is
0.5 to 7.0.
Turn Mode
Same procedure as in AUTO mode.
