Wish you were in northern Chesapeake area; I'd help you in a flash.
The professionals I know are in southern and western
Florida. What I'd suggest is that you
email Jeannie Schreiber. She's a ham,
delivery skipper, and is Secretary of the Waterway Radio and
Cruising Club. She lives in Palm Coast, just south of
Jacksonville and may have some good ideas about how to resolve your problem.
Her
email is: Jeanie Schreiber <secretary at waterwayradio dot net>
