As my old pal Dirk says, "I'm always in the s**t, it's only the depth that varies"!

Hi CH,
No I haven't. I think Humber use fag packets. Just guessing.

Apologies to your wife.

JW.

The best advice I can give is speak to Ace marine in FiFe.they are stability consultants and Naval architests and see what the costs are for a accurate Centre of gravity of the boat with all the gear in her,and the best place to put the Kad 300 and tanks.

They may be able to help but without a weight table it may cost more.?

If your not interested in RCD then freeboard doesnt matter.Its just the best position for the engine.

You will feel happier and so will I.

Should cost not more than 200.aprox Maybee,Hopefully?

Ok having slept on your problem about where to put the engine/tanks,I can confirm that in my humble oppinion that given the Hull weighs aproximatly 1 ton and the engine weighs over half a ton and we floated a 30 ft rib that was down by the stern with a Kad300 in her in Autoship and she was realy low at the back end,in fact the water was 4 inches up the tubes.I can say you have in my oppinion no alternative than to move the engine forward or the nose will be in the air with just the two of you. I am no stability expert,and have advised of one I personaly can recommend .IMHO

It is critical that the engine/tanks be placed in the right place and I have recommended who I feel can help with this important decision and they can give you a weight table given accurate imformation and work out a accurate CG.

If you are a very competant DIY er then good luck with this project but my experiance of Competant DIY ers boats is not impressive.



Good luck with it and I hope it works out fine.

Ere, CH, it looks like you've done a bit of an "about turn" on this one! I'm impressed, that takes guts!

No about turn but its a big job and needs somebody who knows what he is doing,Maybe JW does and I hope so,but if not then its talk to a proffesional if you want a chance of succes.Its not my boat and there is a lot of decisions already made that I would not make personaly. I have the Kad drawing of a 30 ft with a Kad in her and will show you what it looks like when floated in Autoship , it has the engine at the stern with a lot of weight up front

This project is not for the faint hearted or them that guess.

Be happy

OK CH, but you're still putting all these "alleged" gods of techno on much too higher pedestal! you must accept that there are plenty of people out there with excellent "gut" feelings on this stuff, who will very often show your pen & mouse pushing consultants a thing or two. That's not to say some of them aren't brilliant! The designer I mentioned earlier in this thread, Bill Malloney, is exactly that, most of his stuff is a combination of "gut feeling" and "mathematical know how" if his 31 footer hits the water, I'm sure it would be a fabulous rib.

Regards,
