Drive type
The drive type setting controls how the autopilot drives the steering
system. You should set the drive type when commissioning the
autopilot (see page 61).
Rudder damping
Set this option during the initial dockside checks if the autopilot
‘hunts’ when trying to position the rudder (see page 62).
Magnetic variation
If required, set this value to the level of magnetic variation present at
your boat’s current position – indicated as east (
VAR EAST
) or west
(
VAR WEST
). The autopilot sends this variation setting to other
instruments on the SeaTalk system, and it can be updated by other
SeaTalk instruments.
AutoAdapt
The AutoAdapt feature allows the autopilot to compensate for
heading errors at higher latitudes, which are caused by the increasing
dip of the earth’s magnetic field.
The increased dip has the effect of amplifying rudder response on
northerly headings in the northern hemisphere, and on southerly
headings in the southern hemisphere.
