I frequently sail in a river with significant
current.
There is no
current diagram in the NOAA Tidal Current
Tables for my sailing area (Cape Fear River).
So, I generated a current diagram and speed lines
to predict the best times for departure and transit time.
However, it seems like there should be a simple app or program
(Open CPN
plugin??)
that can provide an accurate
route planning in a tidal
river.
Does anyone know of such an app or
plugin?
