Ok, time to throw in my chicken.
All these arguments are because Macca wants the min. weight raised so the "big manufacturers" as we call them, can build a heavier boat than anyone else can, at the same price. Hmm. If we raise the min. weight, their boats can be competitive.
Of course, as he says you could get AHPC to build an all-carbon Viper and shed 30kg, to make it 107kg, at a gazillion times the price of a Blade / Stealth etc, and it will be a whole 3 or 5kg lighter than the Blade. Hmmm.
Sounds like we have a whole lot to be worried about. (Note : I have been told I have an overly-enthusiastic sarcasm gland.)
The very sad thing is that through all the responses he is getting, he will collect some F16 owners who are like-minded, and will stop at nothing to acchieve his goal - he has proven this beyond a doubt with his persistence.
One has to ask what his objectives are and why so persistent - in one of the threads he was linked to being a pro sailor with an affiliation to a manufacturer. I`d stop guessing his motives right about when that was disclosed.

Now for my last comment - Why do we need the "big manufacturers" for support, when we have the new, innovative builders, some small, some not so small (think Vectorworks), who are willing to build to the rules, understanding the fine line between weight, strength, stiffness of platform, cost of manufacture, and reasonable profit margins. They might not hit all the targets on the bullseye, but they get very close in all respects, and produce a hard-to-beat package, which is why the "big manufacturers" are crying - they can`t compete and it`s starting to hurt.
Perhaps the "small manufacturers" are the big manufacturers of the future. Perhaps the catamaran sailing scene worldwide no longer needs (or can sustain)big manufacturers with big profit margins.
Perhaps the reason the big manufacturers have to have big profit margins is so they can pay big names to sail their boats, in the hope of selling more boats to the average joe (us.) Perhaps the Pro sailors are getting nervous...(see previous note on sarcasm.)
