Transport Canada, (Canada's aviation regulator), calls it a "seaplane rating", and does not differentiate between operating a flying boat and operating a float-equipped aircraft. Canadian chart supplements for water aerodromes refer to "seaplane operating areas". I've heard the term "float-plane" used more by passengers than "seaplane". I've even heard "pontoon-plane" used on a few occasions. When the average joe sees the huge Martin Mars water bomber fly overhead, I don't think "flying boat" is the first thing that comes to his mind. Vancouver-based Harbour Air calls itself "The World's Largest All-Seaplane Airline". Seattle-based Kenmore Air also refers to its "seaplane" fleet, yet you can book a "Floatplane Picnic" through them. EDO, the world's largest manufacturer of floats for aircraft, refers to their product as "floats", but makes them for seaplanes.
