Arno XI Hydroplane Scale Model

This 1:8 scale model depicts the Ferrari V12-powered Arno XI racing hydroplane and was acquired by the seller in January 2025. The model is constructed of wood, plastic, and bright metal and features a plank-style deck, a windscreen, faux side exhaust pipes, a rudder, and a propeller. Inside the cockpit are an upholstered pilot’s seat, a steering wheel, and imitation gauges. This scale model is now offered at no reserve with a display stand in Livonia, Michigan.

Commissioned by Achille Castoldi in the early 1950s, the Arno XI was powered by a Ferrari 4.5-liter V12 and was piloted to a record-setting 150.49 mph in October 1953. It was later owned and raced by Nando dell’Orto, whose name appears on either side of the cockpit on this model. The deck and hull wear a red-tinted varnish and are accented with plank seams and brass rivets. The 1:8 scale model measures approximately 35″ long by 14” wide, and it is accompanied by a black display pedestal.

The upper bodywork is finished in red and features an acrylic windscreen, #50 numerals, Ferrari logotype, and bright metal trim along the perimeter as well as the edge of the aft fin. Faux side exhaust pipes run along both sides, and they are wrapped in rope-style insulation by the cockpit.

The cockpit is trimmed in red vinyl and features a single seat, a headrest, a perforated driveshaft cover, a four-spoke steering wheel, a bright dash panel, and faux gauges.

A rudder assembly is mounted to the transom, and a propeller shaft is mounted to the underside of the stern. Wear is visible on the sponsons.
