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.
You can look up tidal current data for other dates by changing the month, day and year selection boxes. To select another date:
1.Use → and ← to highlight month, day or year, then press ENT.
2.Use ↑ and ↓ to select the desired month, day or year, then press ENT. To clear the information screen, press EXIT.
Tide Information
Navionics charts contain Tidal Information, represented at large zoom ranges by a box icon with the letter "T." The icon stands for a Tidal Station location. An example is displayed at right.
When you zoom in to a sufficiently small zoom range, the icon itself be- comes an animated gauge showing a rising or falling tidal height for the selected station at the present time. At larger zoom ranges, you can se- lect the boxed "T" icon and it becomes an animated gauge with a
