8. Time — The horizontal axis of the graph indicates time, in
accordance with the time format specified in the System
Settings.
9. Minimum safe depth — The blue shaded area of the graph
indicates the point during the tide cycle when it is safe to
navigate your vessel, based on the water depth at that time
and the settings you specified for your vessel in the
Minimum
Safe Depth settings in the Customize menu. For example, the
diagram above is based on a minimum safe depth setting of 5 ft.
10. Depth — The vertical axis of the graph indicates tidal water
depth. The units for the depth measurement are based on those
specified in the
Homescreen > Customize > Units Set-up >
Depth Units menu.
Note: The data provided in the tide graphs is for information
purposes only and should NOT be relied upon as a substitute for
prudent navigation. Only official government charts and notices
to mariners contain all the current information needed for safe
navigation. Always maintain a permanent watch.
