The Dornier Do J Wal ("Whale") was a 1922-1931 "flying boat" seaplane, and an archetype of its kind. Its range and robust build allow it to travel on long missions, such as Roald Amundsen's expedition to the North Pole.

You can carry two pilots, ten people, and roughly 7,000 lbs, according to the wikipedia article mentioning its maximum takeoff weight.
Although the range on the Rolls-Royce-engined Wal is claimed to be 500, other models of the Wal had vastly superior ranges--the 10 to-Wal in particular had a range of 2,200 miles, although there may be a citation needed.
Piloting and Maintenance
According to its real-world equivalent, the Wal uses 87 octane petrol fuel--a readily available fuel that automobiles use.
- As a quirk of it being a seaplane, although its stall speed is mentioned, there seems to be no data on its draft.
- note that Roald landed near the north pole
