Round Britain Powerboat Race

Offshore powerboat racing is a type of racing by ocean-going powerboats, typically point-to-point racing.

In most of the world, offshore powerboat racing is led by the Union Internationale Motonautique (UIM) regulated Class 1 and Powerboat GPS (formerly known as Powerboat P1). In the USA, offshore powerboat racing is led by the APBA/UIM and consists of races hosted by OPA Racing, OSS, and P1.

The sport is financed by a mixture of private funding and commercial sponsors.

In 1903, the Automobile Club of Great Britain and Ireland, and its offshoot, the Marine Motor Association organised a race of auto-boats. The winner was awarded the Harmsworth Trophy. Offshore powerboat racing was first recognised as a sport when, in 1904, a race took place from the south-eastern coast England to Calais, France. In the United States, the APBA (American Power Boat Association) was formed soon thereafter and the first U.S. recorded race was in 1911, in California.

The sport increased in popularity over the next few years in the United States, with 10 races being scheduled during the 1917 season. The sport's growth was disrupted in Europe during World War I and then again in World War II, but it began to grow again on both sides of the Atlantic in the 1950s and 1960s.

The sport entered the modern era in the 1960s, with notable names like Jim Wynn, Don Aronow, and Dick Bertram competing in events such as the Bahamas 500-mile (800 km) race. During that time, the 'navigator' position in the raceboat was extremely important (unlike in today's small, track-like circuits), as finding small checkpoints over a hundred-mile open ocean run was a difficult endeavor.

The list of modern world champions extended into the 1980s, when the sport entered the catamaran, and then the 'superboat' era - the 1000 cubic inch total engine displacement restrictions were lifted for boats over 45 feet (14 m) in length, and soon three- and four-engine boats sporting F16 fighter canopies replaced the venerable 35-to-40-foot-deep (11 to 12 m) vee hulls that had been the sport's top category for twenty years.

Modern races are short, track style events with much improved viewing for the spectators, and the different categories of boats have multiplied far beyond the 4 classes that were common through much of the 60's, 70's, and 80's.

In recent years the biggest number of entries in Offshore races have been for the Cowes - Torquay - Cowes and Cowes - Poole - Cowes races held by the British Offshore Powerboat Race Club.

Class 1 World Powerboat Championship. Class 1 has come a long way technologically since first being sanctioned by the U.I.M. in 1964. Shortly after its advent, Americans Jim Wynne, Dick Bertram and Don Aronow supported technological advancement, with Daytona, Mercruiser, and AeroMarine. In the 1980s European design became more prominent. Don Shead's Aluminium monohulls, Italian manufacturers Picchiotti and CUV, and the James Beard-Clive Curtis Cougar catamarans set the record.Fabio Buzzi took a giant step forward with the introduction of glass-reinforced polymer hulls, turbo-charged engines, and integral surface drives and the 90's subsequently saw the emergence of the Michael Peter's design and Tencara and Victory hulls dominate, with Sterling, Lamborghini, Seatek and more recently, Mercury sharing the power battle.
