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.
Note: The predictions available are sufficiently accurate under moderate
weather conditions, for the coastal areas served by the reference station, 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.
