Tide Info
The Tide Info feature is the combination of a new tide heights database that will be included within
new C-CARDs and new features which calculate the tide graph for all primary and secondary ports
world-wide. This function can calculate the tide heights for any past or future date and as a by-product
of this calculation will also display the Maximum and Minimum Tide height and time for the day
selected plus the times of Sunrise and Sunset. At some chart levels, the chart plotter will display a new
Tide Diamond Symbol for every Port or tide point in the database covered by that particular C-CARD.
Tide Stations
Finds the nearest Tide Stations (up to 10) on the map, from the boat position - if a valid fix is received
- or from the cursor position - if the fix position is not good.

Tide & Currents
The new worldwide database with tidal stream information is now available with MAX C-CARDs.
When data/time is available, Tidal stream arrows are shown on the charts, indicating the direction and
strength of the Tide.

If no data/time is available from the GPS or the chart plotter is not in Simulation mode, the icon on the
map is generic one.
The color of the arrow denotes the strength of the current as follows:
0 to 0.1 kn -
0.2 to 1.0 kn -
1.1 to 2.0 kn -
2.1 to 3.0 kn -
