A long-serving member of Team New Zealand has broken ranks to become the first to question publicly the legality of Oracle Team USA's boat during the last America's Cup.
Nearly a year after Oracle's stunning victory, Kiwis are still flummoxed by how Emirates Team NZ lost the regatta after being 8-1 up.
At the time, there were rumours Oracle had employed an elaborate electronic stabilising device, but Team NZ kept quiet on the speculation.
But in an interview with Australian yachting e-magazine Afloat.com.au, Team NZ weather guru Roger "Clouds" Badham said he believed Oracle used a computer-based stabilising system that pushed the boundaries of the class rules.
"They were just so far outside the class rules that no one had ever considered them," he said. "The system was so sophisticated and so elaborate that the measurers just did not fully understand it."
