3D boat selection
Determines which icon to use on 3D charts.
Boat settings
The boat settings are used when calculating an automatic route.
The boat's draught, width and height must be input to use the
autorouting and easy routing features.
Note:
Ú Autorouting is not available in Insight units, or in any
unit used in U.S. territorial waters.
Range Rings
The range rings can be used to present the distance from your
vessel to other chart objects.
The range scale is set automatically by the system to suit the chart
scale.
Extension lines
Sets the lengths of the heading and course extension lines for your
vessel. For setting extension line lengths on other vessels shown as
AIS targets, refer to AIS "Course extension lines" on page 144.
A: Heading
B: Course Over Ground (COG)
The lengths of the extension lines are 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 for your vessel.
Your vessel heading is based on information from the active
heading sensor and the COG is based on information from the
active GPS sensor.
Synchronize 2D/3D chart
Links the position shown on one chart with the position shown on
the other chart when a 2D and a 3D chart are shown side by side.
Pop-up information

you select the item.
