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 Wa-
ter 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 ← → to highlight month, day or year, then press
ENT.
2. Use ↑ ↓ to select the desired month, day or year and press
ENT.
To clear the information screen, press

Tide Information
NauticPath charts contain Tidal Information,
represented 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.
