Minute Markers
In order to maintain a visual presentation of your vessel’s previous movements, you
can draw these with a line. This line is drawn after the vessel symbol in the SN90

markers to the line to indicate the travelled distance for each minute. The minute
markers are shown as small circles on the vessel’s track line.
To draw the line use the settings on the
Track Line
page. The
Track Line
page is
located in the

dialog box. The
