Sir Michael Fay, the man behind New Zealand's first America's Cup challenge, once described the Auld Mug as the hardest prize to win in world sport.
The reason it is so tough? "You have to get through two years without making a mistake."
Team New Zealand's mistakes in last year's loss to defenders Oracle Team USA have emerged piece by piece since the gun sounded in that heartbreaking final race on San Francisco Bay last September.
This week, skipper Dean Barker shed further light on the team's missteps in San Francisco, pointing to a decision made by syndicate head Grant Dalton to agree to a lay-day when they had the option of racing as a key error. He also admitted there was tension among the crew over Dalton's inclusion in the sailing team.
