1913: A curious flyingboat: unequal-span wings, pusher propeller set between parallel tail booms and a typical Clement-Bayard tail; the fuselage nacelle built onto a wide flat pontoon-float, with large tip-floats under each wingtip. The 115 hp 4-cylinder Clement-Bayard in the hull drove the Chauviere propeller through shafts and gearing.
