between the reds and greens has been all that's been required so far.

That won't be sufficient. You need to know where the shoaling is and
that's why I suggested getting an ICW cruising guide that lists problem
areas. I've run aground in the channel when I didn't head the guides.
You're in a non-tidal area now, so I think that you're pretty much OK, but
you'll want this on your return trip.
