The fine finish on this 1:10 scale Riva speed boat by Derrick Hill, seen at the 2018 Bristol show, is clear. The detail of this model is also outstanding. It is to be hoped that the Bristol show and exhibits like this will return before too long.

The roots of classic Riva yachts go right back to 1842, when Pietro Riva began repairing and building yachts on Lake Iseo in northern Italy. His great-grandson, the legendary Carlo Riva, was to create a range of wooden-hulled speedboats that were to become part of la dolce vita.

Carlo was inspired by the products of Chris-Craft, for which he was an agent, and he used Chris-Craft and Chrysler engines in the Riva yachts. The first twin-engine classic range Riva yacht was the Tritone (below) built from 1950-1966. The Super Tritone version is valued in hundreds of thousands of euros.

Less expensive was the Riva Junior shown here with Ms Bardot.
