The Class is sub divided to ensure a range of options are available to those who wish to race. The various sub divisions form the original 'modern' offshore racing that created powerboat racing as we know it today.

    V24 powerboatV24 is a high performance gulled-wing race boat. The power unit for this race boat is an inboard small block 5.7 litre V8 engine.

    The boat is only 24 foot long and weighs 1450kg in race form and has a 320 HP engine. - giving an interesting power to weight ratio of 215 HP per ton.

    The V24 runs with a full enclosed canopy and its own safety air supply with the crew sitting side by side secured by a six point safety harness.

    These boats run on courses close to the shore providing a visual and loud spectator experience.

    V24's run one design race rules, with no modifications allowed to the boats or engines which makes the competition tight and spectacular.

    These boats are fun, fast and very loud.  


    The engine capacity is 551cc to 750cc (Yamaha and Tohatsu 40hp). Boat length is: 3.9M minimum, width 1.7M, weight 75kgs minimum.

    P750 racing is a high adrenalin, high action sport with explosive wave-jumping and tight competitive surf racing in a tunnel hulled inflatable boat. The crew consists of a driver steering the boat and a co-driver who uses their weight to stabilise the craft and obtain maximum speed.

    Marathon Racing

    marathonIf you were to discuss modern-day long distance powerboat racing with anyone younger than 30 chances are they will know little of the origins of the sport in Britain and even less of the personalities behind it’s rebirth in the 1960’s.  

    It is because of people like Lady Vi Aitkin, Fiona Countess of Arran, Tim, Powell, Clive Curtis, James Beard and others too numerous to mention who made their mark no matter how large or small that the sport has been able to develop even through it’s highs and lows and because of them that we are here today. These are the pioneers of “Marathon” racing which had its humble beginning’s in the 1960’s but rose to a pinnacle in the 1970’s and the 1980’s with the greatest races of all the Round Britain Powerboat Race.

    These races, together with the Cowes Torquay Cowes Races were to inspire a revolution in the safe, seaworthy and capable craft that families use today., no matter what the size. The inception of the first Cowes Torquay Cowes Powerboat race in 1961 set the standard for the rest of the world to follow. The sport, created in Europe by Sir Max Aitken, was to become the proving ground for some of the most famous designers, builders and engine manufacturers in the marine world today.

    If Sir Max had not been inspired by the 250 mile Miami Nassau race of 1959 and set about bringing the sport to these shores, would we have built the reputation this country has achieved for the past four decades resulting in an industry now reckoned to earn worldwide in excess of some £3 billion.

    One of the greatest and toughest Marathon races of all time is the Round Britain Powerboat Race which has now been run three times, first in 1969 organised by Crab Searle, then the second one in 1984 by Tim Powell and the third in 2008 by Mike Lloyd. These long distance endurance/marathon races, at 1400 miles the longest in the world test boats engines and crews to their limit and provide manufacturers a unique testing ground for their products and to be able to explore these limits that their products can achieve. The end result is more reliable boats and engines. As the saying goes, racing improves the breed.

    The British Powerboat Racing Club is now at the centre of the development of Marathon Racing in the United Kingdom with Lord Maxwell Beaverbrook, son of Sir Max Aitkin, together with his sister Laura, now taking over the reins and providing the impetus for the future development of the sport.  Obviously the Cowes-Torquay-Cowes races are at the centre of this development but it would appear that other clubs such as UKOBA and The Royal Motor Yacht Club are now beginning to resurrect their heritage to Marathon racing and helping with its development. Long may this continue.

    Powerboat P1 SuperStock

    Powerboat racing

    The London-based P1 management team works closely with the sport's governing body, the Union Internationale Motonautique (UIM), the RYA and the wider marine industry to develop the sport internationally at all levels.  

    Powerboat P1 is the rights holder for both the P1 SuperStock race series and P1 Aqua X jet ski racing. Powerboat P1 has created a marine racing platform combining the key pillars of accessibility of entry, parity of performance and affordability across a variety of watercraft to ensure offshore Powerboat racing remains future proofed for racers, teams and commercial partners alike.

    P1 SuperStock

    The P1 SuperStock Championship for the first time offers a series where competitors can race the same brand new boat the P1 Panther 28-SS. When racing with the same boat, same engine, and same performance the only difference between winning and losing is you.

    P1 SuperStock pilots battle it out on the water through every turn and every wave jump. It’s an acid test of a team’s ability to command the boat through demanding conditions.

    The fusion of these elements creates dramatic racing and changeable race leaders, on a course that can be radically different with each lap. All the action can be easily viewed from the shore by huge crowds of spectators and it’s all captured on film and televised in high definition for a global audience.

    SuperStock race courses are tight, two miles in length and are run close to the shore. There are typically 5 rounds or race weekends in a season and racers get up to three 20 minute races over a weekend. The teams battle all the elements to win their National Championship, earning them the right to race in a World Championship in 2015.

    Putting a P1 SuperStock team together is simple and there are various ways of doing this: by purchasing a new or second-hand boat, leasing one for a season, or taking up a P1 'arrive and drive' race package. This means that a season of racing in the SuperStock UK national championship, in front of live crowds around the country and a worldwide television audience, can cost a little as £20,000.    

    The UK Championship comprises two classes of boats - the P1 Panther 250 powered by Evinrude 250 High Output engines and the P1 150 for the smaller 21ft racer with Honda engines.

    Typical venues for the 'Grand Prix of the Sea' race events include Plymouth, Weymouth, Southampton, Eastbourne, Hull and Liverpool.  

    To find out more visit or call Powerboat P1 on 0207 170 4250.

    All racing is carefully supervised by trained RYA powerboat racing personnel and licences are issued only after a satisfactory standard has been reached.
