2. STEERING MODES
2-17
Orbit turn
In the AUTO mode, your boat orbits around its current position. For the NAV mode,
the boat orbits around the (last) waypoint. This function requires a chartplotter or GPS
navigator.
Spiral turn
The boat spirals in the direction of current heading (STBY), set course (AUTO) or the
course to the next waypoint (NAV) that was active at the moment that the spiral turn
is started.
The boat will continue to spiral until the or AUTO key is pressed.
Note: In the NAV mode, if the boat does not enter the arrival alarm area, the NAVpilot
does not switch to the next waypoint. To prevent this, set the arrival alarm range as
large as possible and activate the perpendicular function on the chartplotter.
