• The system changes from High profile to Low profile when the
speed decreases to 8 knots (= Transition speed minus 1 knot)
The active profile (
'Low
' or '
High'
) is shown in the autopilot page
(e.g. AP44) and in the autopilot pop-up (MFDs):

Set rudder zero position
Used to correct the rudder zero position found during dockside
commissioning if the boat needs a small rudder offset in order to
steer straight.
Ú
Note:
Setting rudder zero position should always be done in
calm conditions, where steering is not affected by wind and/or
current.
Bring the rudder to the position where the boat steers straight, then
activate the
Set rudder zero
option to save the rudder zero
parameter.
Ú
Note:
On dual engine boats, verify that the engine RPM is equal
on both engines so that the thrust from both propellers is
equal. Otherwise, the zero rudder position might be set wrong.
Set turn rate
Used for setting the preferred turn rate of the boat.
Bring the boat into a turn with the preferred safe and comfortable
turn rate, then activate the
Set turn rate
option to save the turn
rate parameters.
Ú
Note:
The captured turn rate will be stored in the active
steering profile. This setting must therefore be repeated for
each steering profile.
