12/31/2010. The Fokker Aircraft Corporation of America Model 9 was originally a Dutch design, however, after development in the USA, there was only a superficial resemblance with its Dutch ancestor.

After the Dutch-built Fokker B.III biplane flying boat had been offered unsuccessfully for sale to the Dutch Navy, it was converted to a six passenger aircraft in 1927, and redesignated B.IIIC Anthony Fokker shipped the flying boat to America. Here it served as a model for a new amphibious monoplane design designated F-11, which became a new aircraft of mixed Dutch-American construction.

Initially it was planned to fit the basic B.III design with a landing gear, a fully enclosed cabin, and an American Super Universal wing. The needed modifications to attach the new wing to the hull were so extensive it was decided to design a new hull. As the American factory was unable to build a metal hull, one was ordered from the Fokker factory in Amsterdam, the Netherlands, and shipped to America, where it were assembled with the US-built wing.

Designated F-11 Flying Yacht by Fokker in the USA, the prototype was a six-passenger amphibian with retractable landing gear sponsons. Power plant was a 425 hp Pratt & Whitney Wasp pusher engine, and registered N7887 it was first flown in 1928. As pictured here, it was later converted into a flying boat with wing tip floats. The F-11 was marketed by the Dutch factory as the B.IV.
