On the chart, the course vector on the ground COG is represented by a red arrow. The magnetic heading line is represented by a green line. Both are variable in length.

Open the app settings by tapping on the ⚙︎ icon, then select the My Boat section.

• The length of the heading vector is defined in minutes of time, from 0 up to 300mn. In example, 30 minutes on course at a 6 knots speed displays a vector of 3 nautical miles. This vector varies depending on your speed. You can disable the arrowhead.
• The heading line is set by distance on the chart, from 0 up to 300 NM. In example 20 nautical miles.
