"We've got a pretty impressive bunch of designers in the chase [boat], tweaking it and making sure our starting package is as good as it can be", said Burling. "There's more on the table".
"I still see myself as steering the boat ... We've proven we can races against these guys if we sail well but if we make too many mistakes like we did today then we won't win races".
