That is for Marathon racing - Class III is totally different!
Go to The RYA Rules Page for the complete up to date rules on these classes.
Another place is the Offshore Racing Drivers Club - feel free to ask more questions when you've waded through that lot!

Hi - a link to the UIM rules for offshore - class 3 has it's own section.
But to give a quick situation check:
3A - has hardly ever been raced in this country
3B - has been popular, then declined. There is a big move to make this popular again and a real drive to boost numbers for 2011
3C - one of the main classes historically in the UK, but numbers have fallen away and don't know if it will continue in 2011 in the UK?

Just as an observation, from watching classic footage it is a shame that 3c is not 21 phantoms and rings etc any more, racing looked alot more affordable and accessable back then, did the intro of big cats and clever mono's effectively out price it's self? Love watching the old boats doing london to calais etc. Would a national class only of this nature get interest back? May be promoting races like cpc as a basic could be an idea, I am toying with the idea of doing it this year. Good luck!

3a
During UIM GA last weekend a new 3A-class was introduced. It is 115hp monohull racing. I'll try to find the rules for that class.
My personal opinion on it is that it is not that well thought trough. Wy do we need yet another class with 115hp engines on the international level? Would it not be better to look over the 3B-class rules?

3A Rules
This was the proposal and I thin it was accepted without any adjustments.
Class 3 A
Hull: Mono Class letter: A Max volume: 1800 cc Max power: 115 hp Length: 5,75 – 7,00 m
Width: 1,50 – 2,00 m Min weight: 550 kg
Buoyancy: Hull measurement Class 3A
GRP 280 l, comp, 160 l
All hull measurement are to be taken while the boat is ashore.
The length must be measured between perpendiculars of the external moulded length of the boat, taken at the extreme bow and the interface between the hull/bracket and engine.
Hull extension beyond the transom shall be deemed to be “fixed trim tabs” and shall not be included in the measured length.
Hull extensions added to the bow and/or any extending parts, rubbing strakes,
fenders, stabilizing trim tabs and rudder assemblies are not to be included in the
measured length.
When defining “extreme bow”, any form that constitutes the bow and its construction
and contributes to the performance of the boat shall be included in the measured
length. Any other attachment that is added to meet a minimum length requirement
shall not be included in the measured length.
Justification
Class 3A has not been raced for many years. Introduction of a mono hull class 115 hp engine will make it easier to start racing offshore. A width limit for monohulls will prohibit high cost boats with wings.
To make rule simple and clear and avoiding designs that are intended to make shorter length measurement and therefore a lower min weight, the length dependent weight is deleted. The length is to be measured from the front to the interface between the hull/bracket and engine.
Class letter will adjust adjust § 710.6

That's just 3b with out cats! If this is the sort of rash decisions being made it explains an awful lot.

Class 3B could be good for 2011, hears a cut and paste from a couple of documents.
The Class 3 B Worlds were granted to the UK with the provision that both the venue and date must be confirmed by the end November 2010
Class 3B is really only supported in Norway (14 boats), Finland (10 boats) and Sweden (1-2 boats). GB is expected to field 8 boats in 2011, so it would be reasonable to expect an International entry list of 15 - 20 boats.

If your post was to gather information with intention of racing in the future you could consider OCR
http://www.ocrda.org/
I've just completed my first season as navigator in A9 with Bob McCarthy (OCRDA on here)its been a great learning curve for me and I've enjoyed every minute,planning next year to race myself subject to raising the funds.I don't think there's a better grass routes type of racing that will be any cheaper or more fun and I've met a great bunch of people.Most of the racing takes part in the South West so your in the right area.PS Thanks Bob for a great introduction to boat racing.Nic

thankyou all for showing an awful lot of interest, what i am wanting to try and do is to prepare a boat for racing either next year or 2012
but the boat is an old boat it is wooden
it has raced already in her life, i have been informed that it competed in and finished the london-paris race
so my main interest would be in an historic version unless the boat would be acceptable in main racing, but being made of wood might make it not acceptable
any views from anyone

Jon,
It was a Swedish proposal which was passed at UIM, although I'm assured that the width is 1.6m and the minimum weight is 700kgs including crew.
It does appear to overlap with Class 3B, which might cause confusion, but as 3A has not been raced in Europe for many years, it was probably intended as a stock sub-division of 3B.
Nic has a good point, OCR 'A' already exists, 1800cc for stock ski boats, no wings allowed in here.
Malta also has a 115 hp class and the French Federation, run by Offshore Passion, has a Stock Sport 100 hp class, which acquitted itself very well in Corsica.

Yes !! OCR will be the way forward with classes similar to offshore passion in France and offshore in Ireland
Basically if it floats it will be eligible !

i take it these types of racing boats run single engines,
is the safety set up the same as the big boats
like radio , and all safety set up
i know you need helmets and personal safety life belts and the such
but what is needed on these circuit racers
