2. STEERING MODES
2-16
2.6.4 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.
2.6.5 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 spiral speed can be set in the menu. In the NAV mode, the boat steers
toward the waypoint(s) spirally. The arrival alarm must also be active on the chartplot-
ter.
The boat will continue to spiral until the AUTO or STBY key is pressed.
Note: 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.
