18.1 Tides mode
In Tides mode the Tides animation control is displayed onscreen and the
Tide station and Current station symbols in the Chart app are replaced with
dynamic graphics which identify Tide and Current conditions. You can use
the animation controls to play Tide and Current predictions for a 24 hour
period. The own vessel Tide vector is also enabled in Tides mode.
Note:
• The Tides mode is only available if you have cartography that provides
the Tides and Current data. Refer to your cartography provider for more
information.
• The Tides mode requires accurate date information, usually taken from
the GNSS (GPS) position data available to your MFD. Alternatively, you
can input a specific date manually.
