American Magic went even faster at 47.59 knots in a victory over INEOS Team UK and then 47.37 knots again in beating TNZ in the opening day of racing.
In September, NZME reporter Matt Brown went on board American Magic's AC75 Defiant and witnessed the speedometer reach 41 knots. However, chief executive Terry Hutchinson later showed data that proved the boat went even faster.
Ironically it was the lack of wind that cancelled the Christmas Race regatta, Team New Zealand's last chance to race against their rivals before the America's Cup in March.
