Position Offset
Position Offset
You can offset the vessel position to allow for differences between the GPS
and paper chart data. This may be useful if you are using a datum that is not
available on the Chartplotter, or if you are referring to a paper chart drawn to
unknown datum.
You can change the offset by moving the cursor to the known vessel position.
This offset is applied to all incoming position data. The default offset value is
zero.
When position offset is switched on, all displayed vessel position data is
annotated
(C)
to indicate it has been corrected.
➤ To switch the position offset on/off:
1. Select the
POSITION OFFSET
option, then press the
OFFSET OFF ON

tion data and the vessel is displayed at the corrected position.

POSITION OFFSET
option, then press the

sor position is displayed in a position offset data box.
