All good points and everybody will have their own opinion / perspective on this. Personally I have enjoyed the sailing from a technical aspect. It is difficult to see a 72 ft cat screaming along on foils at 40 knots and not wonder about how exhilarating it would feel to be on board that!! And I say that being a committed mono-hull devote.
Having said that I loved the 12s and always felt it was a shame to see them dropped as the Americas Cup class. But then it was noted once that I don't like change

.
Where this (and recent) A Cups have lost it for me is in the dilution of the national representation aspect. Sure we have Oracle Team "USA" constantly referred to by commentary as "the Americans" but he boat is being driven by an Aussie with the brains trust another Aussie (Slingsby) and a Pom (Ainslie). There is not much American about that. Lets have a State Of Origin Americas Cup!
Whatever your opinion, you would have to say that the coverage of the event along with all the electronic graphics has been great to see. It's certainly made it more interesting and made a much wider audience tune in.
So can the Kiwi's find a way to scratch out one more win or do the Oracle boys have too much momentum?
