I have been in those! Used to take Chalk’s Flying Service, seaplane outfit, out of Miami to Paradise Island about six times a year. Usually stayed at the Britannia Beach Hotel. There is a scene in Thunderball where they are moving the bombs through a canal. It was part of the property of the hotel. Like Chalk’s it is long gone now, built over by the Atlantis complex. Have not been back to the islands since the 80’s.
Me either, spent two summers there sailing on a relatives boat. I need to go back sometime, maybe golf at Norman's course in Great Exuma.
