It worked for me, Andre. You need 'Macromedia Flash Player' to view it - maybe that's the problem?
They certainly look very nice - typical 'Med' styling. I couldn't see much technical information though. There's a bit about the actual length, beam, tube material, etc but nothing (that I could see) about the hull design! I couldn't even see a picture of the hull so how it would ride is anyone's guess!!
It may be worth finding an Italian forum and asking the question there. I believe Manos knows some good European sites.
Edit: just tried to view again and now it's 'Service unavailable'. Perhaps it can only cope with one person looking at it at a time!
Edit: have now seen some pics of hull but cannot make out details such as chines/splash rails!
