The Ferrari Hydroplane Arno XI is inspired by Achille Castoldi in the early 1950s and built by the Cantiere Timossi boatyard, located in Azzano (a frazione of Mezzegra) on the 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.

The engine used is a 4.5 liter “Lampredi V12” which was previously installed in a Ferrari 375 F1. By adding two compressors and special quadruple carburetors and converting to methanol operation, it was possible to further increase performance. In the end, the formerly 380 hp (280 kW) of the basic engine were compared to well over 500 hp.
