Originally developed by the Nardi Company, the Riviera amphibian first flew in December 1952. Siai-Marchetti purchased manufacturing rights from Nardi and placed the four-seater into production in 1960. A New Jersey firm handled all United States sales, and the Rivieras were assembled by Southwest Airmotive. The four-seater is powered by a 250-hp six-cylinder Continental engine mounted on top of the fuselage behind the cabin in a pusher-prop arrangement. For water use, the landing gear folds up into the fuselage behind the cabin, and the small nose gear is hidden behind nose gear doors. Forward visibility through a large bubblenose windshield is excellent. Production of the Riviera ended in early 1966 after 30 airplanes had been built.
