[[Class 1 World Powerboat Championship]].
The technology of [[Class 1 World Powerboat Championship|Class 1]] has advanced considerably since the class was first 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.{{Citation needed|date=September 2015}} 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.{{Citation needed|date=September 2015}} [[Fabio Buzzi]] made a large technological advance by introducing glass-reinforced polymer hulls, turbo-charged engines, and integral surface drives and the 90's subsequently saw the emergence of Michael Peter's design and Tencara and Victory hulls dominate, with Sterling, Lamborghini, Seatek and more recently, Mercury sharing the power battle.{{Citation needed|date=September 2015}}

Weighing around five tonnes, each boat in the [[Class 1 World Powerboat Championship|Class 1]] fleet is approximately 12-14m in length, 3.5m wide, and constructed using composite materials. All the boats were [[catamarans]] until 2019, when monohulls were permitted again.<ref>{{Cite web|date=2019-05-12|title=Class One International – The Reboot|url=https://www.powerboatracingworld.com/class-one-international-the-reboot/|access-date=2021-02-22|website=Powerboat Racing World|language=en-GB}}</ref>

===Venture Cup===
In 2012, it was announced that a new series of 'ultra-marathon' offshore races would be run every two years under the title of the Venture Cup. The first race was scheduled to take place in June 2013 from Cowes in the UK to Monte Carlo; many consider the 1972 London to Monte Carlo race to have been the greatest powerboat race ever.<ref>Archived at [https://ghostarchive.org/varchive/youtube/20211205/icQ5rYk93qc Ghostarchive]{{cbignore}} and the [https://web.archive.org/web/20190110092651/https://www.youtube.com/watch?v=icQ5rYk93qc&gl=US&hl=en Wayback Machine]{{cbignore}}: {{cite web| url = https://www.youtube.com/watch?v=icQ5rYk93qc| title = London-Monte Carlo PowerBoat Race | date = 22 August 2013 | via=[[YouTube]]}}{{cbignore}}</ref> The Venture Cup is billed as the World's longest, toughest and most prestigious powerboat race. The 2013 race was however cancelled because of lack of funding and replaced by a Prologue.

In 2015 the Venture Offshore Cup was announced. The race was to be run around the entire coast of Ireland, beginning in Cork and ending in Dublin with multiple stops en route. However, in May 2016 the organisers cancelled the race again.

===P1 SuperStock Championship===

P1 SuperStock is a single class powerboat race series.  It has international recognition and guaranteed media exposure and is broadcast on TV. P1 SuperStock is approved by the sport's governing body, the [[Union Internationale Motonautique]] (UIM), as an international class of powerboat racing.{{Citation needed|date=September 2015}}

P1 SuperStock is a major sporting festival over five or six weekends in May through October. There are up to six races over the race weekend, lasting 30–45 minutes each. The free events attract thousands of spectators and often run alongside the AquaX jetski series. All teams race in P1 Panther race boats with 250HP outboard engines.

Powerboat P1 Management Ltd is the rights-holder for Class 1, P1 SuperStock and also owns the rights to Powerboat P1 World Championship and P1 AquaX. In the US, a wholly owned subsidiary, Powerboat P1 USA, manages all aspects of Offshore racing throughout North America.<ref>{{cite web| url=https://p1offshore.com/About-Us|title=About.

Boats in the 250+ hp class are {{convert|28|ft|0|abbr=on}} sport racers powered by a 250+ hp engine. This propels the boat to speeds up to {{convert|70|mph|0|abbr=on}} in flat water, and its lower centre of gravity provides greater stability and improved handling.{{Citation needed|date=September 2015}}

===UIM Powerboat GPS World Championship===
The series was officially founded as Powerboat P1 World Championship in May 2003 in Nettuno, Italy. Twelve boats, the majority of which were Italian, raced in the first-ever Grand Prix of the Sea. Starting out with 15-year-old aluminium boats, Powerboat P1 boats evolved dramatically through the decade to the point where the mono-hull twin-engine boats were developing around 1800&nbsp;hp.
