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.

Tide Information
NauticPath charts contain Tidal Information, repre-
sented at large zoom ranges by a box icon with the
letter "
T ." These icons will appear when you are
zoomed in to a 6-mile range. The icon stands for a
Tidal Station location. An example is displayed at right.
When you zoom in to a sufficiently small zoom range (0.8 nautical
mile), the icon becomes an animated gauge showing a rising or falling
tidal height for the selected station at the present time. At larger zoom
ranges, you can select the boxed "
T " icon and it becomes an animated
gauge with a pop-up name box. The name box disappears seconds.

Icon animates automatically without selection at the 0.8-mile zoom
range (right). In the example above, the tide is at 0.9 feet and falling,
as shown by the down arrow at the top of the icon.
