Chapter 4: Using the Chartplotter
87
Vectors are set on and off using the Vector Length option in the Chart Setup menu,
as described on page 31. The length of these lines is determined by the distance
your boat will travel in the time you have specified (3 mins, 6 mins or infinite) at
the current speed.
If INFINITE is selected the vector will extend to the edge of the chart window.
Note:
If the course over ground (COG), speed over ground (SOG), or heading are not
available, the corresponding vector cannot be displayed.
... using Cross Track Error (XTE)
When you are following a route or going to a waypoint, you can restart the XTE.
This sets the XTE to zero and moves the origin to the actual vessel position.
Restarting XTE is useful if you find yourself off track and want to go straight to
your target, rather than get back onto the original track.
... using the Course Deviation Indicator (CDI)
The CDI assists with accurately maintaining your course to your destination. A
‘rolling road’ in three dimensional perspective provides a real-time display of your
boat’s course.
