The Farman F.51 was a 1920s French maritime reconnaissance flying boats designed and built by Farman. The F.51 was an unequal-span four-bay biplane flying boat with a crew of four. It was powered by two Lorraine-Dietrich engines mounted in tractor configuration. A pusher engined version was designated the Farman F.50 (even though the designation had been used before in 1919).
