The symbol indicates tide height data is available for that position on the
chart. When you select the tide height option, a graph of predictions for
maximum and minimum tide heights is displayed, data for sunrise and sunset
is also provided as illustrated Figure 5-3.

weatherconditions,for thecoastalareasserved bythereferencestation, to be
used for navigation planning. However, certain weather fronts and storms
can alter tidal patterns and influence predicted times and heights.
The cursor, represented by a dotted vertical line on the graph, is used to select
a time for which the tide height is displayed.
You can use the soft keys and trackpad to change the date for which tide
information is shown.
