1957 Riva Ariston

The 1957 Riva Ariston is a 21-foot wooden speedboat built during the model's continuous evolution under Carlo Riva's management. This particular example represents a key moment in the Ariston's development: it features the diagonal triple-layer hull construction introduced that year, along with the framed windscreen that made the boat suitable for year-round use. Power comes from a Cadillac gasoline engine, installed following the hull extension undertaken in 1956 to accommodate this alternative powerplant.

The boat reflects the refinements Riva introduced throughout the late 1950s. The interior shows updates including upholstery work and instruments typical of the period. The windscreen, dashboard, and hardware represent the standard specification for this production year, with construction details emphasizing quality throughout.
