16.8 Chart 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 3 motion modes are:
• Relative Motion (default)
• True Motion
• Auto Range .
Note: In the 3D chart view, only Relative Motion mode is
available.
The current motion mode applies to the active instance of the
chart application.
When you pan the chart the motion mode is no longer active.
This is indicated in the status bar by brackets around the motion
mode — for example, (Relative Motion). This enables you to
view another area of the chart whilst navigating. To reset the
motion mode and return your vessel to the screen, select the
Find Ship icon or select Find Ship from the menu. Manually
changing the range or panning the chart in auto range also
suspends motion mode. The default setting is relative motion
with the boat icon positioned in the center of the screen. The
mode that you select is restored at power up.
Boat positions (Relative Motion only)
Position Example
Center
Partial
Offset
Full Offset
When the motion mode is set to Relative Motion, the position
of your vessel is fixed on-screen and the chart picture moves
relative to your vessel. You can use the
Menu > Presentation
> View & Motion > Boat Position: menu options to determine
whether the vessel is fixed in the center of the window or offset.
If you change the position to Partial Offset or Full Offset, the
view ahead of your vessel will be increased.
