My geuss would be commercial filling stations (large nozzles, high flow) to avoid "blow back", am I right CH?

Your being very presumptious, the truth is, very few boats start as any more than a drawing on a fag packet by a person who has a feel for the job!
With respect, you do have a bit of an obsession with forms, paperwork and rules, in the real world, these are often created AFTER the boat just to satisfy the rules and regs!
Take Revenger as an example, designed in the early eighties as a Twin v6 outboard powered sportsboat/4 litre raceboat by Shead I believe, it had very poor sales until the deck was altered to a cruiser design. It was in this form powered by Twin v8 petrol engines that it had huge amounts of success as a Cruiser Class raceboat, although as a pleasure boat it still had poor sales.

In the early/mid 90's, the hull was made into a rib, ranging in size from 23-29', powered by single & twin v6's, v8 petrols and various diesels. I believe somewhere along the line Lorne Campbell was called in to alter the spray rails.

So to summarise, you take a ski boat, make it into a cruiser, then turn it into a rib, and when you have done all that, you write the paperwork for CE certification. Not the correct way of doing things according to Crazyhorse, but it seems to have worked!

The bottom line hear in my humble oppinion is will the company who makes the boat and it has to be assumed they know what they are doing ,

Will they warrant the boat when its done with your own ideas factured in,I suspect not.

You may be lucky and get it right and make improvements,which will mean the manufacturers will be thinking your a genious,My guess is out of the 10 people who move there engines around and try and make improvements to another persons boat design they end up with a odball,and they become the only collector of the boat, in the main.
You have to give rib designers and boat builderes credit for what they do,and they know there hulls and designs,and what works and doesnt.

You can get away with a diesel in the transome on some boats as they were designd with the beam and can take the weight,but to try and move a engine forward cos you think it will stop a sea from comming over the bow? is not recommended unless a person who knows your boat and design and weight tables can demonstrate it works better than a inboard at the stern which if you get it wrong will not be too bad,as most desingd ribs have the extra boyancie anyway.

Thats my take on this project so far,unless it transpires that Humber will warrant the project and the boat passes all MCA tests and RCD cat B then I am sticking to my oppinion.

Good luck anyway,Its not my boat and I have explained what I would do in the same situation.In the hope it stops somebody doing the same withought proffesional advice or the support of the designer/builder.

Be happy

On the paper trail Question,I would rather take my chance on a boat with certification and testing and under written by guarantee if poss, than a boat that was designd well and was changed and therfore is gambling then on who is more experienced the builder designer or the person who makes the changes.

I know what I would rather be in on when it blows up.

Unless it is demonstrated that JW is a navl architect or has access to one or the Builders underight the changes and there fore believe its beneficial for the boat ,then I know which boat I would prefer to be out on in bad weather and when the time commes to sell which I would have the best chance of getting the best price for.
