UIM 2014-2015 Year Books Coming Soon
Whereas the RYA is the national governing body for powerboat racing in the UK, the Union Internationale Motonautique (UIM) is the international governing body, to which the RYA is affiliated.
To find out more about the UIM please see 'Related Links'. Also, click on links above relating to the latest announcements regarding F1 and F2.
You will be able to download the international rules, obtain advance regulations for events and find out racing results throughout the year.
Important note to Super Licence competitors: You must inform the RYA by the end of each year, ie by November, if you wish to hold a Super Licence for the following season, and which category. This is then submitted to the Circuit Racing Commitee (CRC) and UIM. You must also obtain a copy of the UIM requirements for Super Licences at the beginning of each season, and these can be obtained from their website.
The circuit classes which participate on an international level are:
- F1 (UIM Super Licence class only) - see UIM website
- F2 (UIM Super Licence required) (known nationally as NS2000)
- SST120 (USA)
- F4 (known nationally as S:850)
- SST45 (USA)
- T:850 (raced nationally)
Note: most hydroplanes are raced nationally and grouped under the "outboards" category on the racing calendar.
P750 (known nationally as Thundercats)
