Water speed record

• From 1909 to 1927 the record was an unofficial listing from the organisers of powerboat races.
• In 1928 the record category was officially established.
• From 1930 the rules of the record stipulated that a craft must make two runs over a timed kilometre course in opposite directions, with the record being the average speed of the two runs.
• The record is currently ratified by the UIM (Unions International Motonautique).
  With an approximate fatality rate of 50 %, the record is one of the sporting world's most hazardous competitions.
  

  1920s

  
  During the 1920s powerboat racing was dominated by American businessman and racer Gar Wood, whose Miss America boats were capable of speeds approaching 100 miles per hour (160 km/h). 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 92.83 mph (149.40 km/h) on the Detroit River. The next year Gar Wood took the same boat up a waterway Indian Creek, Miami and reached 93.12 mph (149.86 km/h).
  

  1930s

  
  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 record breaker and racing driver Sir Henry Segrave was hired to pilot a new boat called Miss England. Although the boat wasn’t capable of beating Gar Wood’s Miss America, the British team did gain experience that they put into an improved boat. Miss England II was powered by two Rolls-Royce aeroplane engines and seemed capable of beating Wood’s record.

Following Segrave’s death, Miss England II was salvaged from the lake and repaired. Another racing driver, Kaye Don, was chosen as the new driver for 1931. However, during this time Gar Wood recaptured the record for the US at 102.16 mph (164.41 km/h). A month later on Lake Garda, Don fought back with 110.223 mph (177.387 km/h). In February 1932, Wood responded, nudging the mark up by one mph (1.6 km/h).

In response the continued American challenge, the British team build a new boat, Miss England III. The design was an evolution of the predecessor, with a squared-off stern and twin propellers being the main improvements. Don took the new boat to Loch Lomond in Scotland, on July 18 1932, improved the record first to 117.430 mph (188.985 km/h), and then to 119.810 mph (192.816 km/h) on a second run.

Determined to have the last word over his great rival, Gar Wood built another new Miss America. Miss America X was 12 metres long, and was powered by four supercharged Packard aeroplane engines. On September 20 1932, Wood drove his new monster-boat to 124.860 mph (200.943 km/h). It would prove to be the end of an era. Don declined to attempt any further records, and Miss England III became a museum piece. Wood also opted to scale-down his involvement in racing and returned to running his businesses. Somewhat ironically, both of the daredevil record-breakers would live to their 90s. Wood died in 1971, and Kaye Don in 1985.

Boat design changes

Wood’s last record would be one of the final records for a conventional, single-keel boat. In June 1937, Malcolm Campbell, the world-famous land speed record breaker, drove Bluebird K3 to a new record of 126.33 mph (203.31 km/h) at Lake Maggiore. Compared to the massive Miss America X, K3 was a much more compact craft. It was 5 metres shorter and had one engine to X's four. Despite his success, Campbell was unsatisfied by the relatively small increase in speed. He commissioned a new Bluebird to be built. K4 was a ‘three pointer’ hydroplane. Unlike conventional powerboats, which have a single keel, with an indent, or ‘step’, cut from the bottom to reduce drag, a hydroplane has a concave base with two floats fitted to the front, and a third point at the rear of the hull. When the boat increases in speed, most of the hull lifts out of the water and runs on the three contact points. The positive effect is a reduction in drag and an increase in power-to-weight ratio - the boat is lighter as it doesn’t need many engines to push it along. The downside is that the three-pointer is much less stable than the single keel boat. If the hydroplane’s angle of attack is upset at speed, the craft can somersault into the air, or nose-dive into the water.

1940s

Campbell’s new boat was a success. In 1939, on the eve of the Second World War, he took it to Coniston Water and increased his record by 11 mph (18 km/h), to 141.74 mph (228.11 km/h). The return of peace in 1945 brought with it a new form of power for the record breaker – the jet engine. Campbell immediately renovated Bluebird K4 with a de Havilland Goblin jet engine. The result was a curious-looking craft, whose shoe-like profile led to it being nicknamed ‘The Coniston Slipper’. The experiment with jet-power was not a success and Campbell retired from record-attempts. He died in 1948.

1950s

In 1952, Sayres drove Sho-Mo-Shun to 178.49 mph (287.25 km/h) - a further 18 mph (29 km/h) increase. The renewed American success persuaded Malcolm Campbell’s son Donald, who had already driven Bluebird K4 to within sight of his father’s record, to make a push for the record. However, the K4 was completely out-classed and Campbell could not run at the speeds of the Seattle-built boat. In 1951 K4 was written-off when it hit an submerged object on Coniston.

At this time, yet another land speed driver entered the fray. Englishman John Cobb, was hoping to beat 200 mph (320 km/h) in his jet-powered, all-aluminium built Crusader. A radical design, the Crusader reversed the ‘three-pointer’ design, placing the floats at the rear of the hull. On September 29, 1952, Cobb tried for a 200 mph (320 km/h) record on Loch Ness. Travelling at an estimated speed of 240 mph (386 km/h), Crusader's front plane collapsed and the craft instantly disintegrated. Cobb was rescued from the water but died of shock soon afterward.

Two years later, on October 8 1954, another man would die trying for the record. Italian textile magnate Mario Verga, responding to a prize offer of 5 million lire from the Italian Motorboat Federation to any Italian who break the world record, built a sleek piston-engined hydroplane to claim the record. Named Laura, after Verga’s daughter, the boat was fast but unstable. Travelling across Lake Iseo at close to 190 mph (306 km/h), Verga lost control of Laura, and was thrown out into the water when the boat somersaulted. Like Cobb, he died of shock.

Meanwhile, Donald Campbell had been working on a new Bluebird - K7, a jet powered hydroplane. Learning the lessons from Cobb’s ill-starred Crusader, K7’s floats were forward of the cockpit. The craft was almost too stable: when Campbell first tried out K7, the boat’s bow wouldn’t lift out of the water. After modifications, Campbell set a new record of 202.32 mph (325.60 km/h) on Ullswater in 1955. Campbell and K7 would hold the record until June 1967, increasing it 276.33 mph (444.71 km/h) in the process.

1967

Lee Taylor, a Californian boat racer, had first tried for the record in April 1964. His boat Hustler was similar in design to Bluebird K7, being a jet hydroplane. During a test run on Lake Havasu Taylor was unable to shut down the jet and crashed into the lakeside at over 100mph. Hustler was wrecked and Taylor was severely injured. He spent the following years recuperating, and rebuilding his boat. On June 30 1967 on Lake Guntersville, Taylor and Hustler tried for the record, but the wake of some spectator’s boats disturbed the water, forcing Taylor to slow down his second run, and he came up 2 mph (3 km/h) short. He tried again later the same day and succeeded in setting a new record of 285.21 mph (459.00 km/h).

1970s to the present

As of 2005, Warby’s record still stands. There have only been two official attempts to break it. Lee Taylor tried to get the record back in 1980. Inspired by the land speed record cars Blue Flame and Budweiser Rocket, Taylor built a rocket-powered boat, Discovery II. The 40-foot long craft was a reverse three point design, similar to John Cobb’s Crusader, albeit of a much longer length. Originally Taylor tested the boat on Walker Lake in Nevada but his backers demanded a more accessible location, so Taylor switched to Lake Tahoe. An attempt was set for November 13 1980, but when conditions on the lake proved unfavourable, Taylor decided against trying for the record. Not wanting to disappoint the assembled spectators and media, he decided to do a test run instead. At 270 mph (435 km/h) Discovery II hit a swell and one of the floats collapsed, sending the boat plunging into the water. Taylor’s body and his destroyed craft were never recovered. In 1989, Craig Arfons, nephew of famed record breaker Art Arfons, tried for the record in his all-carbon-fibre Rain X Challenger, but died when the hydroplane somersaulted at 300 mph (483 km/h).

Despite the high fatality rate, the record is still coveted by boat enthusiasts and racers. Currently there are three major projects aiming for the record. The British Quicksilver [1], The American Challenge project [1], and. spurred into action by the new challengers, Ken Warby has also built a new boat [1].

In 2001, Bluebird K7 was raised from Coniston Waterb by members of the Bluebird Project.
