Thanks. That is very clear now.

Legs and lower backs have bigger muscles than arms, shoulders and upper backs. NZ definitely played a blinder with their boat design and it's showing in how they sail it. They have so much more capacity to control the surfaces on their wing due to the optimum levels of hydro pressure they can maintain.
NZ 6 - USA 1
I think it'll be all over by 2pm EST tomorrow. Sadly, I cannot see Oracle pulling off a repeat of their SF comeback.

Interesting, thanks.
Why did Oracle, as the defender, choose Bermuda as the site, over SF Bay, SD Bay, Newport, etc?
