5 3D Steer
3D Steer displays a road-like view of the current leg of your route,
as seen from your current position and looking towards the next
waypoint.
It shows:
• the roadway - the clear area between the grid lines. Ideally,
this should be in the middle of the screen.
• the centerline - the white, broken line that represents the line
between the previous waypoint and the next waypoint.
• the boat icon - your vessel's position in relation to the
centerline.
• the name and number of the next waypoint, and the distance
and bearing to it.
• any XTE (cross-track error).
• your SOG (Speed Over Ground) and COG (Course Over
Ground).

3D Steer. The GB40 displays a graphical
representation of the view from your vessel to the next
waypoint. If your vessel is:
◦ on track, 3D Steer shows a XTE reading of zero. The
roadway is in the middle of the screen, with your vessel on
the centerline.
◦ off track, 3D Steer shows a XTE reading.
5.2 3D Steer: Reset the XTE
Reset the XTE when you're off track and decide to steer directly to
the next waypoint from your current position; rather than steering
back to the original track.
You can also reset the XTE from the
Chart screen.
Check that the new route between your current position
and the next waypoint is at a safe depth and contains no
hazards or obstacles.
