CH my dear friend, please don't take this the wrong way as I'm not spoilling for a fight or trying to insult you but, could you give us an idea of your actual experience within the field of fast-ish planing hulls/boats, I don't mean by that, anything you may have read about, or heard of, or been told, I mean wot you've actualy done!, beit using of, puting together yourself, building, (looking at pictures dosn't count)

None but I do know people who have the experience and I listen and get proffesional advice if I think it is needed,

I have built my own yacht from purchasing a bare steel hull and fitted her out .

But I am no boat builder or designer and do not purport to be one,I leave that to the experts.

But I have my views based on those that I think do know what they are talking about and in my oppinion have real experiance of what works and doesnt work in a rib and I gree its not always the proffesional but usually they have used them for important jobs at some time.

There are a number of things that you have said that I disagree with,for egsample you have not checked out anything with regardes to what this boat is designd for,and have simply said yes good idea,You have said that SS tanks are crap when they are plainly not as people use them.

We have differnt ideas and come to our own conclusions,I believe you are respected in boat racing circles but that doesnt mean you know all about putting a Kad 300 In a Humber 8.5 1.5 mtrs from the stern .You are not the diffinitive and neither am I or otherwise we would all be using your boats/ribs.

Dont take this the wrong way as I feel you have a lot to offer on racing hulls and performance but before you say yes that a good idea dont you think we need a little more imformation to come to that conclusion?

CH,
Thank you for your honesty!
The word "Racing" is only a word, the goal of it is to go as quickly as poss between two places, these being the start and finish,
the best way to do that is to put a boat together that will do this as safely and comfortably as you can, this means a ballance AND hull type that will give the best poss stability in pitch AND roll, with as little jarring and high "G" loadings as you can.
So, whilst you and JW aren't trying to "race" the same basic requirements/rules apply.
this is of course asuming you want to travel at a reasonable speed, I have to geuss you do, or you would get a displacement craft and everything would be much easier, so we are not so far apart in our goals as you may think!

I agree with your sentiments exactly, but I am sure you would also agree that to use an existing design of rib and put a Kad300 in her, where you think it should go? is not the way forward to achieve your goal of well ballanced boat/rib without real specilist advice or a proffesional eye?

Its is used as a offshore rib and has either Outboards or diesel single and is respected as a good sea boat as is,I know of none with a forward mounted engine.and none with a Kad 300 in Yet as the engine has only been out for over a yr.She goes well with a dieasel so Im told, but the way some manufacturers could get round the warrantie and stability problems for RCD in my oppinion is bye selling recreational craft as work boats. Im am also of the personal oppinion that it is not good practise to get a none Ce maked hull only from a re sale point of view if you want to sell at a later date to a recreational user.

Any changes you make from the norm may mean re evaluation when sold to comply with RCD for cat B at owners risk and builders may have no warrantie issues if you fit your own engine.Thats the way as I see it. Unless somebody can convince me different?

Am I correct in thinking that a self build doesn't have to conform to CE regs, but it can't be placed on the market for a minimum of 7 years ( maybe 5) after completion.

And is it not feasible that a "self build" could be a hull & deck, and in the case of a rib, tubes, that you finish off yourself.

This in my oppinion is a self build project in the eyes of RCD and maybe the MCA so any changes will be looked at in depth for its use when requiring conformaty to either or if sold on the recreational market as a offshore boat within 5 yrs or when applying for MCA work boat code.IMHO
