3.3.2 Selecting sailing method of NAV mode
Your vessel may go off course when navigating between waypoints in the Nav
mode. This can happen when, for example, a command is received from a
remote controller. To get you back on course, two methods are available,
COURSE and XTE. (See figure in below.) If COURSE is selected, the
NAVpilot-511/520/611 will calculate a new course based on your new position
after dodging, etc. that will take you directly to your destination waypoint. If XTE
is selected, the NAVpilot-511/520/611 will use XTE or cross track error to steer
the boat towards your ORIGINAL course before dodging. You may select, either
COURSE or XTE as shown below.
