Drift angle* The angle measured in degrees between ship’s heading and the actual
movement. When drift angle is to port, a red “◄” appears and when it is to
starboard a green “►” appears. In the NAV mode, drift in water tracking speed
is shown.
Trip Shows trip distance. The distance is referenced to fore or fore/aft depending
