Yes. It's been quite awhile since I've traveled any East coast waters,
but I remember there POSSIBLY being one or two along the Carolina's,
between Atlantic City and New York, Boston to Cape Ann? You'd have to
look at various charts (any of the above may be wrong or no longer exist
..... as I say, old memories BG check the charts).
As for your second part .... correct, but here you are talking about a
channel which, for the most part, is taking you from the East to a point
inland, to the West (loosely).

Are red and green buoys ever set alone and for anything but a channel?
I've never seen one without the other. Offshore from Va Beach we have
many marking the shipping channel approaches to the Chesapeake bay. As
I recall they are alway RRR approaching from the north or south.
