If you want to know about the Tool than the best is to ask Piet about it and not assume a lot of things. I can tell you that the most parts are carbon and than we are talking about 95% or maybe more. The platform is extremly stiff and reliable.
I can tell you this because Piet is my father and i am close to the development of The Tool as you can be for the European market.
I think also that the Tool will be the A-class to beat the coming time, if seen the downwind performance of that boat with 18 to 20 knots and it is really flying and no other type could do this, his was during the A-cat Nationals in Holland. With less wind the boat was also quicker (down and up wind)
On the website of Catamaranparts (www.catamaranparts.nl)there will be soon more info about the boat.
The price for the boat is also not to bad if you see the carbon prices the last time .

Hans
