Understanding the
cross-track display
On the steering screen
The STEERING screen uses a traditional display that shows
cross-track distance as how far your vessel symbol is from the
center line of the display (your course line). When your vessel
symbol points towards the course line, you’re moving closer to
the line; when it’s parallel to the course line, you’re keeping a
constant distance from the line; and when it points away from
the course line, you’re moving further from the line.

The two short vertical lines near the sides of the screen show
the limits of your cross-track distance. This same distance is
also displayed in numbers near these vertical lines. If you go
over this cross-track distance limit, the 958 issues an alarm
and your vessel symbol will flash. To display this alarm
message, press the STAR key. To clear the alarm, press the
CLEAR ALARM menu key. To adjust the cross-track limit, see
”Choosing the cross-track scale” starting on page 171.

Note: The direction your vessel symbol is pointing tells you
the direction you’re actually travelling. The direction may not
be the same as your heading, if any current or wind is present,
or if you’re moving at a very low speed.

NOTE:
If you’re following a route and the 958 sequences to a new leg, your ves-
sel symbol will show your COG relative to the new leg and should be
straight ahead once you’ve finished turning the vessel.
