The Model C training seaplane was the first “all-Boeing” design and the company’s first financial success.
A total of 56 C-type trainers were built. Fifty-five used twin pontoons. The Model C-1F had a single main pontoon and small auxiliary floats under each wing and was powered by a Curtiss OX-5 engine.
The Navy bought 53 of the Model C trainers and the Army bought two landplane versions with side-by-side seating. The final Model C was built for William Boeing and called the C-700 (the last Navy plane had been Navy serial number 699). Boeing and Eddie Hubbard flew the C-700 on the first international mail delivery from Vancouver, British Columbia, Canada, to Seattle on March 3, 1919.
