3D boat selection
Determines which icon to use on 3D charts.
Range rings
The range rings can be used to present the distance from your
vessel to other panel objects.
The range scale is set automatically by the system to suit the panel
scale.
Extension lines
Sets the lengths of the extension lines for your vessel and for other
vessels shown as AIS targets.
Select to show or hide the heading and course extension lines for
your vessel.
Extension length
A: Heading
B: Course Over Ground (COG)
The length of the extension line is either set as a fixed distance, or to
indicate the distance the vessel moves in the selected time period. If
no options are turned on for the vessel then no extension lines are
shown.
Your vessel heading is based on information from the active
heading sensor and the COG is based on information from the
active GPS sensor.
For other vessels, COG data is included in the message received
from the AIS system.
ForwardScan
If you have ForwardScan and this option is selected, the
ForwardScan heading extension is shown on the chart. Refer to
"Heading extension" on page 174.
SonarChart Live tide correction
When selected, the tide correction feature uses information from
nearby tide stations (if available) to adjust the depth values used by
SonarChart Live as the sonar is recorded.
