Named after the ancient name for Lago d’Iseo, on whose shores stood Cantieri Riva, the Sebino is a compact and simple boat, five metres long with an open sunbathing area behind the front bench seat, a precedent for the deck designs of the later Junior and Olympic.

It was the first boat that Carlo Riva designed for mass production to a single design, and in this way a forerunner of the range of boats that followed. All the 119 boats built were powered by Chris Craft 60 horsepower engines, the supply of which he secured on a visit to the United States in 1952. It was superseded by the Florida in 1957.
