Water speed record


The World Unlimited water speed record is the officially recognised fastest speed achieved by a water-borne vehicle. The current record of 511 km/h (318 mph) was achieved in 1978.

With an approximate fatality rate of 85% since 1940, the record is one of the sporting world's most hazardous competitions.

Until 1911 the world water speed records were held by steam-powered, propeller-driven vehicles,

In 1911 a 12 m (40 ft) stepped planing hull, Dixie IV, designed by Clinton Crane, became the first gasoline powered vessel to break the water speed record. Beginning in 1908 Alexander Graham Bell and engineer Frederick W. "Casey" Baldwin began experimenting with powered watercraft. In 1919, with Baldwin piloting their HD-4 hydrofoil, a new world water speed record of 114.0 km/h (70.86 mph) was set on Bras d'Or Lake at Baddeck, Nova Scotia.

During the 1920s powerboat racing was dominated by American businessman and racer Gar Wood, whose Miss America boats were capable of speeds approaching 160 km/h (99 mph). Increased public interest generated by the speeds achieved by Wood and others led to an official speed record being ratified in 1928. The first person to try a record attempt was Gar Wood's brother George. On 4 September 1928 he drove Miss America VII to 149.40 km/h (92.8 mph) on the Detroit River. The next year Gar Wood took the same boat up a waterway Indian Creek, Miami and reached 149.86 km/h (93.12 mph).

Like the land speed record, the water record was destined to become a scrap for national honour between Britain and the USA. American success in setting records spurred Castrol Oil chairman Lord Wakefield to sponsor a project to bring the water record to Britain. Famed land speed racer and racing driver Sir Henry Segrave was hired to pilot a new boat, Miss England. Although the boat wasn’t capable of beating Wood's Miss America, the British team did gain experience, which was put into an improved boat. Miss England II was powered by two Rolls-Royce aircraft engines and seemed capable of beating Wood's record.
