This is the Ferrari Arno XI Racing Hydroplane and is, without a doubt, the most beautiful speedboat ever made. Its 1953 Flash Gordon design still feels beautiful today. It's not only a design masterpieces. It's an incredible machine too.
This one of a kind ship - sold on a May 12, 2012 auction for about a million dollars - packs a "4,493.73 cc Ferrari Tipo 375 F1 V-12 engine with twin superchargers and twin four-choke carburetors" on its 6.2-meter Timossi di Azzano three-point racing hydroplane hull. It only weighs 1,763 pounds (800 kilograms) which, coupled with its power, allowed to set the "world speed record in its class on 15 October 1953, at 150MPH (241.708 km/h.)"
