The reason why Mattia decided to enter the 18HT class is that they actually sell very few Formula 18.
On the contrary, before the launch of the Hobie Tiger, they were the biggest producer worldwide of Formula 18 cats.
I suspect also that the 18HT project is not new, but "recycled":
Mattia 18HT bow resembles very closely the one of the Laval Jeantot designed Mattia Dynacat.
Th remaining parts come from different sources: the mast from RIBA (the same of BIMARE Javelin 2), the rudder from Dotan (they look very heavy) etc.
I am ready to bet that this boat will be a "fiasco".
