Until the arrival of the Aquarama, the Tritone was the most important model in the Riva stable, the largest and most expensive boat, and the only to be equipped with twin engines. Its size, power and long range (thanks to large fuel tanks) made it an ideal boat for sea-cruising, and it did much to forge Riva’s reputation in the Mediterranean. Evolving from the BQ 69 designed in 1950 it was given its name in 1953. Its hull design drew on the Corsaro, with the addition of a second row of seats in the cockpit, behind which the stern area was completely decked and used as a sunbed.
A total of 257 boats were built between 1950 and 1966, and there were three versions in addition to the basic model. The Super Tritone was slightly longer with more powerful engines; 21 were built between 1960 and 1963. The Tritone Cadillac, meanwhile, was powered by twin 250hp Cadillac engines; ten were built between 1956 and 1960. Finally, the Tritone Aperto, upon which the Aquarama design drew directly, had an open sunbathing area at the stern; 15 were built in the early 1960s.
