Tidal Current Information

Navionics charts contain Tidal Current information, represented at large zoom ranges by a box icon with the letter " C ." The icon stands for a Tidal Current

Station location. An example is displayed at right.

When you zoom in to a sufficiently small zoom range, the icon itself becomes an animated arrow showing tidal current velocity and direction for the selected tidal station at the present time. At larger zoom ranges, you can select the boxed " C " icon and it becomes an animated arrow with a pop-up name box. An example is displayed in the following figure.

To view Tidal Current information:

1. Use the arrow keys to move the cursor over a Tidal Current Station icon. When selected, a pop-up name box appears.

2. Press WPT to display the Tidal Current Information screen.

Current Information screen.

The Tidal Current Information screen displays daily tidal current data for this station on this date at the present time. The graph at the top of the screen is an approximate view of the flood and ebb pattern for the day, from midnight (MN), to noon (NN) to midnight (MN). The velocity scale at the top left side of the graph changes dynamically based upon the maximum velocity of the current for that day.

Slack water, the period of little or no current, is represented by the

Slack Water Line (SWL). The flood appears above the SWL and the ebb appears below the SWL.
