I don't know either, the web site doesn't give much away re motors, but if for example they usualy fit a kad32, fitting the 300 would move the C of G aft quite a bit, in that case moving the motor fwd a bit, maybe not as much as 1.5m, but a bit, would get the C of G bach where it should be, clearly you can't make it any lighter, but it would be far better to maintain the right ballance.
imagine how the single O/B's CofG compares with the kad300's, miles apart! they probably just "get away" with most of these details with the average boat being "less than ideal".

On a serious note, I do think you have too much faith in "alleged" experts, this may be born out of your newness to fast boating, but to think only a few tallented and qualified individuals hold all the secrets to making a boat work is i'm afraid naive.
There are highly respected designers, in this country and others, who will design you a race boat, on testing it's not unusual to find the boat unsafe or uncompetetive, the same designer will then charge you again for work on trying to get the thing to work!
I've seen this go on for months with some boats, even years, and not always geting there in the end either. and I'm talking "well known, respected" designers! On the other hand, many of the most successfull boats that have ever raced have thier roots "on the back of a fag packet" from the man with the "feel for it"

you know what mathematicians or accountant's are like, if the trusted formula tells them 10 +10 is 31, they'll believe it!

Most boat builders work round the basic Hull mold in the hope it will be all things to all men,As to produce a Hull mould for each engine weight and configuration would put you out of buisness pretty quick.

I do not have faith in all purported proffesionals/designers as the way I see it most get it wrong,some more than others.There are very few succsesfull designs commercially,and given the number of boat designers they must produce more than one each yr therfore a lot must go bye the wayside.

I am aware of the difficulties in producing a good boat with optimised performance and feel you have to put everything in your favour,to have a chance of getting it right,This means talking and listening to all views weather it be a user,a teacher,designer,engine man, marine consultant,Naval architects, Surveyor ,experienced user. Hero and non hero and sticking it all into a pot and seeing what comes out.

I have to say you dont need qualifications,but you do need luck and a bit of common sence.

We agree only if you agree that this is a job for some proffesional /experianced advice,if you want to have a good chance of getting the ballance right. or be a gambler with less odds in your favour

Sorry CH,
I've been boating most of my life, putting together, rigging, setting up, testing, and racing all sorts of different boats for all sorts of applications both for me, and for all sorts of customers, for racing and just for pleasure, many of which were from bare boats, trying along the way loads of differing ideas.
I'm quite happy to carry on relying on my own educated guestimations as they've served me well so far.
I think there's nothing better than to teach one's self the hard way, so just do it, and if it's not right, just do it again!

I know, stubborn SOB, that's me.
Just ask Dirk he'll tell you!

Well JF your gota get use to a guy like me that wants to help others with there decisions as it isnt easy,and it is so easy to cock up.

I have owned differnt boats for yrs and went offshore as much as possible as I love the Sea.

When I started on my rib project it has taken a lot of Imformation to get to where I am today, and it isnt over yet.

I am no proffesional just somebody who trys to make a informed judgment and trys to make the best decisions he can based on those I respect and there advice.
I have employed what I think is the best and taken for there ideas from hear and rib international as I believe there is a lot of hidden talent on here and I have used what I feel is prudent. It is also my belief that most boat desiners forget what the man in the street realy wants,as he wants commercial proffit.

If I have made a mistakes in my judgments then so be it.

I feel I havnt but I am aware that the proof will be when we use our boat on the water and the sea trials.


So fingers crossed but I feel I have a good team.In my humble oppinion.
