6.2 Vessel position and orientation
Vessel position on the chart display
Your current position is represented on screen by a boat symbol.
The boat symbol is shown below:
D6627-1
Boat symbol
Note: The boat symbol can be customized, so may appear
differently on your display.
If neither heading nor Course Over Ground (COG) data is available,
the vessel is shown as a solid circle. If positional data has been
selected for display, your position will be displayed in the data bar
under VES POS.
Chart orientation
The orientation of a chart refers to the relationship between the
chart and the direction that you are travelling in.
It is used in conjunction with motion mode to control how your
vessel and chart relate to one another and how they are displayed
on screen.
The mode you choose applies to all chart instances, and is restored
at power up.
The following options are available:
North Up (N-up)
In North Up mode, the chart orientation is fixed with true north
upwards. As your heading changes the vessel symbol moves
accordingly. This is the default mode for the chart application.
Head Up (H-up)
Head Up mode displays the chart with your vessel’s current heading
upwards. As the heading changes the vessel symbol remains fixed
and the chart picture rotates accordingly.
Note: To prevent continuous backwards and forwards rotations
as the vessel yaws from side-to-side, the chart will not update
unless the heading changes by at least 10 degrees from the last
displayed orientation.
