The standard formula, as per UIM engine rules is being used.

However, the displacement limits shown in the RB rules are assuming all diesel engines WILL be forced induction, so the 6.5 litre limit is for forced induction diesel engine, OR a natuarally aspirated petrol engine.

If a petrol engne has forced induction, it's capacity will be calculated by multiplying it by 1.4. For example, if you have an engine with a displacement of 8.2 litres, and you fit it with a super/turbo charger, it's capacity will be considered to be 11.48 litres.

So, a pair of blown 5.7 litre small blocks, are from a class rule, considered to be 7.98 litres each.

The common 6.2 litre small block, with blower becomes 8.68 litre.

No, but we dont expect it to be 16 months before the event. I am however very happy with the listing, and I am sure there will be changes as we approach the date, and I am sure that some changes will be forced by the class changes made previously, and also as people get new ideas about what they will run.

Posting the list helps make it real!

Errors and ommissions are acceptable at this time.

ML.

Oki Doki re: the rest, but I would have thought it obvious that Nick wasn't going to be running diesels, as 'the rule change' made them a waste of time, effort & money.
As I understood it from Nick, he had asked you to remove the XS picture from the site, as he wouldn't be running that boat, so maybe there was a misunderstanding.

Whatever happens, he won't be in RB2, he's gonna leave that to the big boys.

Okey Dokey,

I dont mean to split hairs or anything but just so im sure, what constitutes a "Production Motor Cruiser" with regard to MC1 class. Ie. does a certain amount of the model need to have been produced as in the homologation rules of motor racing?

[Burty]

Wheres the list??

[Jon Holmes]

On the Round Britain Web Site.

[Burty]

what the addy?

[Jon Holmes]

Sorry burty,

Dont know how to link!

If you intend to take part but am not sure about your boat let me know what you have including engines etc and I will come back to you.
The problem now is that everyone is panicking and want to get on the listing, we can only handle a certain number of boats (max 65/70) and the rest are having to go on the reserve listing.

[Johnny Rocket]

Do you know whether the smaller RIBs listed meet the minimum length requirements?

I suspect that the 7.5m Scorpion (actually 7.75m LOA) and 7.8m Ribcraft may actually have hull lengths a tad less than 24.5ft. It's certainly going to be close!

[Jon Fuller]

It would be helpfull to post a drawing showing the way UIM hull measurment is done.

It could save a lot of aggro.

I can scan it from PB1 on saturday and post it here, but it really aught to be on the RB site along with the other important rule details.

Is there going to be a requirement for a measurment certificate? Or is it just going to be down to the scrutineers to say yey, or ney when the boats arrive at Portsmouth. If there is, maybe it could be a simplified version, specifically for the RB.

[Jon Holmes]

Well i was seriously considering a Revenger Monza but it would appear that under the UIM rules it would only measure around 28' long so falls outside of MC1. Also its engines are to large to fit in MC2.

I reckon completing the course may prove easier than obtaining a boat to suit the Classes.

Do Revenger include the bathing platform when quoting it as a 30 footer then?

[Jon Holmes]

Yeah,

The overall length is 30'. I am guessing that the forwardmost part of the bow to the end of the keel would be somewhere around 28'9".

It is not super critical right now to do this but we will post this info on the RB web site shortly. Thanks for the offer anyway.

Someone trying to choose a suitable boat may think it is.

I'll stick summat up tomorrow, and that can fill the gap till John sorts the proper job out on the RB site.

[Jon Holmes]

Thinking about it, wouldnt a Phantom P25 fall short of the minimum length of 24.5' required for RB4 under the UIM Rules Jon?

[Jon Fuller]

Don't think so, they've only got about a 12 degree transom angle, so probably lose 3 or 4 inches from the 25 feet max.
