a few reports I've read say Ainsile has made a difference but not a HUGE one, several people are saying Oracle always had the faster boat, it just took them a couple of days to 1)get the new team members working together and 2) they learnt a few new tricks from watching TNZ. Apparently they are tacking in a different way than they were originally (the same way TNZ do) and so where we would take 50 - 100m off them on the odd turn...we're not now
