Timossi-Ferrari 'Arno XI' Racing Hydroplane
The Arno XI is a hydroplane inspired by Achille Castoldi in the early 1950s and built by Timossi Azzano’s Cantieri boatyard located on Lake Como. Castoldi wanted to establish a world water speed record so he persuaded then Ferrari racing drivers Alberto Ascari and Luigi Villoresi to influence Enzo Ferrari to supply him with a 4.5-litre, V12 Ferrari engine; the same engine that gave Ferrari his first Grand Prix victory with the Ferrari 375 F1 at Silverstone Circuit in 1951.[1][2]
Engine modifications
Castoldi managed to further increase horse power by attaching two superchargers. The result was a 502 bhp speedboat, which he used to hit a 150.19 mph top speed in October 1953 on Lake Iseo. That remains the world speed record for an 800 kg boat till today.[3][4]
