"-Well documented handling problems"

Do tell, what were they? Your statement seems to indicate more than what prompted them to extend the hulls. What other things were done to address these "well-known problems"?

"- She was launched first of all boats designed for The Race yet they didn't use that advantage to tune, practise, iron out bugs... Why?"

Are you really asking this? PS had quite a few miles on her with some records to show for it before The Race.

"- She was then rebuilt beyond recognition. The Fosset spin was that this was according to plan and the original hull shape was merely to trick the oposition. Who bought that one? Not me for one. The original hulls must have been a major failure and now they band-aided the design."

Rebuilt beyond recognition? That's funny. The hulls were extended, flowing from the original lines. Previous to that, ballast tanks were added. When the work was done, I doubt anybody sat back and said "gee, what is this new boat"? M&M's take was that they "finally put the right size chasis under the rig". Now, if we want to talk about failures, maybe we should discuss the fact that Dalton had to bring in another design team to reinforce the failing structure of Club Meds hulls and main crossbeam. That Ollier initially refused to give up the structural drawings so the fixes could be made, because they believed they were the only ones smart enough to build such structures. Their conceit could have proven fatal. That those same fixes were truly needed, and were incorporated into the other Ollier cats. Sounds like a major failure that required band aid fixes. And the boats still suffered some delamination. But I won't say the boats were POS because of that, but I don't think you're applying the same standard.

And if we want to credit anybody with ground-breaking designs for The Race - the only one with a ground-breaking vision was Pete Goss. Ill-fated for sure, but maybe he had something there.

Now, a serious question about the boats themselves - it always appeared to me that Playstation and the Ollier cats had a ton of rocker in the keels. The motion displayed in the video to me would seem to be a product of that - given that the other boats also had that feature, I'd love to see video of them in similar conditions. Of course, if you got rid of the hobby-horsing you'd be slamming the whole structure after launching from each wave - potentially a big deal in shock loads for boats that big.
