Setting the motion mode
The motion mode controls the relationship between the chart and
your vessel.
Whilst motion mode is active, as your vessel moves, the chart is
redrawn to keep the vessel on-screen. The three motion modes are:
• Relative Motion
• True Motion
• Autorange
When you pan the chart or toggle Find Ship/Cursor to Cursor , the
motion mode is suspended. This is indicated in the status bar by ‘(
)’ around the motion mode and enables you to view another area
of the chart whilst navigating. To reset the motion mode and return
your vessel to the screen, press
Find Ship . Manually changing
the range in autorange also suspends motion mode. The default
setting is relative motion with zero offset. The mode that you select
is restored at power up. When a chart window is set to
System
view, the motion mode will be set but not synchronized across other
system view windows.
Relative Motion (RM) with optional vessel offset
When the motion mode is set to Relative, the position of your vessel
is fixed on the screen and the chart picture moves relative to your
vessel. You can specify using the
Vessel Offset softkey, whether
the vessel is fixed in the centre of the window (0 offset) or offset by
1/3 or 2/3. If you change the offset to 1/3 or 2/3, the view ahead
of your vessel will be increased.
