第34回アメリカスカップ
With Team New Zealand well ahead in light winds near the end of the fourth leg, the first race on September 20 was abandoned by the race committee due to the race exceeding the 40-minute time limit. Both races on September 21 were postponed by the race committee due to the wind direction not permitting a fair laying of the race course. Due to the late start of race 16, a second race was not sailed on September 23 due to the 2:40pm cutoff time for racing.
本大会では統一ヨット規格として「AC45」「AC72」という2つの規格が新たに定められた。どちらも双胴船(カタマラン)である。
