The 540s plotter/sounder can display graphical tidal data but only seems
to display this data for stations within ~30nm of plotter gps location
but "animated" present tidal data is available anywhere the chart is panned.
Is there any way around this limitation since it makes trip planning
impossible for trips 30nm radially from the planning site?
Clearly the data must exist in the 540 blue chart memory. I was hoping
to avoid having a laptop on board for trip planning.
