Ainslie said: "...wearing my sailor's cap, I have to say that Sunday's racing was about as frustrating as it gets. It is one thing if you are exhibition racing but these World Series races matter, the points go towards the America's Cup proper in Bermuda next summer and, as we saw from Oracle's 9-8 win last time out, every single point counts."

Ainslie, whose mid-series recruitment by Oracle turned the 2013 America's Cup in San Francisco, said he was excited by the emergence of young sailors like Team New Zealand skipper Peter Burling.
Ainslie said: "We have a new generation of sailors coming through...great athletes and a real credit to the sport. We are so close to giving these talented and skilful sailors a format which is rewarding from a competitive view point but also commercially viable.
"What we still need to do is focus on finding the courses that can also better guarantee the conditions which we need to race."
