Achille Castoldi, a passionate motorboat racing enthusiast, made a significant mark in the world of speed records in 1953. Determined to set new top speed records, he commissioned Cantieri Timossi to build a lightweight 800kg class three-point hydroplane hull, which was named Arno XI. For the engine, Castoldi turned to the prestigious Scuderia Ferrari, known for its cutting-edge technology and expertise in auto racing. On the morning of October 15, 1953, Castoldi achieved a remarkable feat by breaking the 800kg class speed record. He set an average "flying kilometer" speed of 150.49 miles per hour, a groundbreaking accomplishment at the time. The following day, he continued his success by setting a new record for the "24 nautical miles" event, achieving an average speed of 102.34 miles per hour, further solidifying his dominance in the world of motorboat racing. In the early 1990s, the iconic Arno XI underwent a comprehensive restoration, bringing it back to its original glory. The boat was later placed for auction at the 1997 Coy's Festival at Silverstone but was not sold. However, the legacy of Arno XI was revived when it was auctioned again in 2012 at the RM Auction in Monaco, where it fetched a remarkable price of $1.12 million, proving the enduring appeal and historical significance of this racing legend.
