okay, so if you want nation / club participation, you'd probably want an affordable (less than $5M) boat that doesn't take too many crew (less than 8 per boat) so you don't have to fork over big money to house/feed/train. If the price is right, you can have multiple entries from a nation/club.

You'd also want some sort of match series or circuit that would draw the clubs/nations in. Maybe like the LV series, but different venues over the course of a year or two (so the boats/teams would have to handle a wide variety of conditions), with the final year being a points/elimination finale leading up to the AC match. The different venues would draw spectators & money to the series and locations, improving relations....

If you want thrills & chills you need boats that can move and cross, bump & run, and can be fixed quickly

If you want spectators, you need fast boats that can work on small courses where viewers can get up close.

Sounds like some variant of the VX 40s to me, doesn't it?
