whirls/disturbance of the water-stream passing the rudder or it is
a single nozzle water jet boat. By manually adjusting the
minimum rudder function, the course keeping performance
might be improved on some boats. This will however increase
the rudder activity.
• Min wind angle starboard / Min wind angle port: This is the
minimum apparent wind angle that will keep the sails well
shaped and give an acceptable thrust. This parameter will vary
from boat to boat. The setting applies for the tack-prevent
function. It also applies when the autopilot is operating in
WindNAV mode. You can select different minimum wind angles
for port and starboard. The difference between port and
starboard will be taken into account when calculating the
Distance To Turn (DTT).
• Navigation change limit: Defines the limits for course change to
next waypoint in a route. If the course change is more than this
set limit, you are prompted to verify that the upcoming course
change is acceptable

Sources
Data sources provide live data to the system.
The data may originate from modules internal to the unit (for
example internal GPS or sonar), or external modules connected to
the NMEA 2000 or via NMEA 0183 if available on the unit.
When a device is connected to more than one source providing the
same data, the user can choose the preferred source. Before
commencing with source selection make sure all external devices
and the NMEA 2000 backbone are connected and are turned on.
• Auto select: Looks for all sources connected to the device. If more
than one source is available for each data type, selection is made
from an internal priority list. This option is suitable for the
majority of installations.
