Not the exact areas you requested but might help
South of Vero gets pricey .
Ft Piece is a bit north of Vero
Harbor town of Ft Piece is a live a board , Nice marina.
Nice boating , direct access too ocean
I was based out of Cape Canaveral and know of a number , again
not in Vero , all north of Vero but gives you a few too consider
Harbor town of Merritt Island is live a board = Nice Marina , ICW ,
access too ocean thru Lock but will be under construction I believe starts
Dec , Then only access too ocean is Sebastian Inlet.
Port Canaveral is direct access too ocean , has a number of live a board
Cape Marina Live aboard , next door too Cape Marina is
Port Canaveral Yacht club is live aboard.
Know nothing of availability but since nobody has responded gives
you a few options .
