Do you remember the impressive RC Arno XI hydroplane? Well, its original version created by boat-racing privateer Achille Castoldi, with a Ferrari engine is now up for grabs. The 4.5 liter 12-cylinder Ferrari engine closely resembles the one found in Type 375 grand prix car, which Jose Froilan Gonzalez drove over the finish line in the 1951 Silverstone GP. The boat piloted by Castoldi averaged speeds well over 150 mph in 1953. It broke the “24 nautical miles” record in the 800 kg category as the ARNO XI averaged 102.13 mph.





When the Italian Powerboat Federation later changed speedboating categories, the record has remained unchallenged till date. The boat will go under the hammer at Monaco courtesy RM Auction. The boat is expected to fetch between $1.3 million and $1.9 million.
