Class
An International Class, equipped with innovative tools,
makes the Diam 24 od a cut above.
The class rules are intended to ensure fairness between racers by boats with similar performance. The whole boat must remain as built and delivered by the shipyard. Even the sails are one-design. The difference must be made on the water, by the racers and not by the boats. The Diam 24od must comply with the class rules of the series and renew its certificate of conformity.

Diam 24 one design regattas schedule
The regattas schedule, from its beginnings in the Tour Voile from 2015 to 2021 has evolved into the organisation of annual national competitions called “World Diam Tour” (WDT). Each competition is made of 5 to 6 events spread over the season for a total of 15 days sailing resulting in a ranking per stage and general, individual and per team/boat for all saison participants.
• Monotypes races
« World Diam Tour Caribbean »: As its name suggests, its navigation zone is in the Caribbean, the fleet being based in Sint Maarten. It starts end of November to end end of April.
« World Diam Tour France »: Organised in France between Avril and October. Its logistic simplifies the organisation of the crews and offers training sessions.
These events combine sport and conviviality, over 2 or 3 day weekends, on specified courses, coastal races, raids and rallying stages
The World Diam Tour is environmentally friendly by its innovative organisation, all regattas are organised to minimise travels, « the spirit D24od, less km = more miles sailed »
• Compensated time racing
This is very popular. When registering for regattas open to all multihulls, the Diam 24od is proving to be very fast and competitive against bigger boats. It has already been measured by several rating systems, Bama, Texel, Mocra, Multi 2000, OMR, SRR… You should know that it is easier to obtain your rating from the Diam 24od rules compliance certificate, than to have to re-measure them all. (Being a series recognised by World Sailing, it is possible to have a series rating when there is a minimum of 5 Diam to race).
