Majsteve,
The F22 looks very much like the :

and
Nations Trophy
Both events (the last is suppost to be a cirquit) are held on 25 ft catamarans with spi and wings that fold upward when the crew is not sitting on them. These boat were sailed by crews of three persons.
They're also a TV and spectator crowd cups often sailed in harbours and bays. Bouys are often quite near to the shore.
I don't know what the status of this cup is now but I used to see some reports on television till one or two years back.
ALso these cups envited sailors from all segments of the sailing sport to the class. Especially the Clairfontaine cup was structured that way.
I guess it is too late now but if it is not then maybe by going 25 ft you have another design in the class and can link up with the experience and cirquit of these two events. It could maybe jump start a US / EU cirquit instead of just the US cirquit.
