Alongside the Aquarama, the Ariston is perhaps Riva’s best known model, and certainly one of its most popular. When production ceased in 1974, twenty-four years after the model was first conceived, over 1,000 boats had been built. Over this period, many modifications were made, not least its length – which ranged from 6.2 to almost 7 meters – and the size of the single engine fitted, which ranged from 105 hp to 350 hp in the Super Ariston, powerful enough to take it to a top speed of 80 km/h

The Corsaro, based on the AR Sport motorboat designed by Carlo Riva in 1946, entered production in 1950. Although only forty were built, it set the scene for later Riva models with its elegant lines and tapering stern. Ranging in length from 4.8 to 5.65 metres, the two-seat boat was fitted with a range of different engines over its lifetime. Only one is known to survive

The boat, Typhoon, was designed back in 1929 by George Crouch. The Typhoon's origin began with Edsel Ford, who was an avid raceboat enthusiast. Knowing the background, and seeing the famous Teaser speedboat in action, Edsel Ford wanted a new fast boat just like it. He contacted the yard that built the Teaser and had an exact copy built, naming it the Typhoon. The Typhoon was a large brute, measuring in at 40' in length with a 2000 cu. in. Wright Typhoon engine, she was made for racing. Edsel Ford never used it as a pure racer, however. His primary use for the boat was as a commuter speedboat between the Ford factory and his home in Lake St. Claire. In 1941, Ford sold it to Howard Hughes who kept it running during the war years, but soon sold it after the war. The Typhoon then went through a series of owners over the next few years ending up in Kentucky. Then in the late sixties, her current owners had her shipped from Kentucky to Seattle Washington. In the late 1960's, at Bryants Marina in Washington, the boat that was docked next to the Typhoon caught fire. The fire raged out of control, and soon engulfed the Typhoon. The Typhoon was a total loss
