JF if your saying you know everything about putting this engine forward and your unhappy that I have given any bad advice say so.

I am not a designer/builder or even purport to be one, but I do know a little about the problems of conformaty to the new RCD Iso regs ,as I have had to comply with these and I have taken into account what I know and have been advised.


I am not questioning your personal knolledge on racing hulls or there developments as I have no experience.

I am sorry for not being in the experienced in what makes a raceing boat go faster but it is not my interest as Ribs are.

I have spent too much time on this simple advice which is get advice if you want to move your engine forward from those that you feel happy and you feel are experienced in doing the job properly.

I mean no insult to anybodys knolledge on this subject but can only say what I woud do if it were mine, as I am looking at it from potential user/future buyers point of view.

CH,
I'm not saying that moving the engine forward in JW's boat IS the correct thing to do, as I have no knowledge of his boat at all!,
All I'm saying to you is, that to install an engine forward of it's standard position may be the correct thing to do if the C of G looks like it may be too far aft as ballance is critical to both speed and rough water performance, this may be the case if the engine in question is heavier than normally fitted or any number of other reasons.
The kad300 may be perfect for his boat as standard, I hope it is,
Just don't assume it's the wrong thing to do coz you havn't seen it before, or it wasn't suggested by a rocket scientist (or a tosser in brussells)

Love, johnny boy

P.S. Anyway, it sounds to me like JW has his own opinions on the subject, so I'm sure he will take no notice whatsoever of a couple of nobs like us. Amen

I think he will agree with you as its to late for any real changes in spec or implications of RCD and all that sort of stuff and who wants to know what I am suggesting could be important.

I wish him well whatever decisions he makes.

Be happy

Wow, started something there.

I'm not siding with anyone on these next comments.

CH, I DIY everything. The old adage, 'If you want a job doing properly, do it your self.' is me. I'm constantly amazed at how dopey professionals and experts can be. Even things which are obvious to others are often missed or not understood.

I don't think I said that.

Let me pass this one buy you.
Example 1,
8.5mtr hull and tubes CG just rear of mid point. Now, inboard at the stern, engine wt. 550 kgs. Consol well forward and 6 people on board sitting at the console each weighing 12 stone. (= 480kgs).
So, now you have 500kg at the stern and 480kg near the bow.
Where is the CG?

Example 2,
Same hull, engine moved forward 1.5 mts. Me and wife sitting just forward of the engine our weight 146kg.
Where do you rekon the CG is now?

CH the above is not indicating critisism of you in any way. But its a very simple example of how reasoned estimates can be used to help solve a problem.

However, I'm open to any sort if insight into problems with the boat, which may be forseen by others. 'Two heeds is better than yin.' Forget Cat B, resale value etc.

I've tried not to upset anyone. Hope I managed.
JW.
