Dean Barker interview: What went wrong at the America’s Cup
Cracks are appearing among the Team New Zealand top brass after skipper Dean Barker questioned the tactics of team boss Grant Dalton at a crucial point of their failed America's Cup campaign.
Barker was surprisingly blunt in his criticism of Dalton's decision to agree to a lay day midway through the 9-8 loss to US defenders Oracle in San Francisco.
Five months on from the galling loss, in which Team NZ squandered an 8-1 lead, Barker says Dalton's agreement with an Oracle request that the teams have a rest day on September 16 was an error.
He also says Dalton was wrong to do so without consulting others at Team NZ.
"That was clearly a mistake. It was a decision that was made outside of our knowledge," Barker told The Paul Henry Show.
"There was a lot going on at the time. I think it was one of those things that we obviously, on reflection, we would had done differently."
The lay day came at a time when Oracle trailed 7-1 but were starting to increase their boat speed.
An extra day gave them time to make further improvements and swing momentum, Barker said.
Barker also confirmed there were "questions asked" by some within the team about Dalton's position on the boat instead of specialist grinder Winston Macfarlane for some races at the regatta.
However, Barker says he wasn't concerned by 56-year-old Dalton's presence.
"Grant was there for reasons other than his physical presence," Barker said.
"He was there for leadership and everything else."
