different course than the second route leg. Notice the new
direction of the north-pointing arrow.
Figure 3: Leg-up chart angle (third leg going south)
Figure 3 shows the same chart, but with the chart's viewing
angle now set to leg-up and the vessel on a different course
than the third leg. Notice the new direction of the
north-pointing arrow.
• Course-up - If you're displaying the charts as course-up
and you press the cursor pad to go into browse mode, if
your vessel changes course, you won't see the chart turn
to the new direction until you fully return to vessel mode
by pressing the VESSEL key. You must be in vessel
mode to see any changed course angle. This feature lets
you keep a steady viewing angle if you're browsing
around on the chart.
• Leg-up - If you're displaying charts as leg-up and the 957
switches to a new leg, you'll see the chart rotate to the
direction of that new leg even in browse mode—unless
you're actively pressing the CURSOR PAD.
If you're displaying the charts as either leg-up or course-up, you may see
a black line with white space on the other side. This line is the edge of the
chart, which is now visible since the chart has been rotated. When the
vessel or cursor crosses the line, the display will switch to a new chart.
