Italian team Luna Rossa, who have been training in Auckland over summer, suffered damage to their wingsail in similar circumstances earlier this year, which was repaired inside two days.
Although the damaged wing is a setback for Team New Zealand, it has served as a timely reminder of the fragility of the cutting-edge racing machines.
While their rivals have endured long stretches off the water, the Kiwi team have had a relatively smooth run in their preparation for this year's America's Cup in San Francisco, avoiding any major incidents.
Oracle's USA-17 had a three-month spell in the shed after suffering catastrophic damage to their wingsail when their boat capsized in rough conditions in San Francisco Bay last October, while Artemis have endured a series of setbacks.
Since re-launching their repaired boat six weeks ago, Oracle have made strong progress in their testing and development programme.
Oracle bowman Brad Webb said on Twitter that the team had another productive day on the water yesterday and expressed sympathy for Team New Zealand's predicament.
"Good day for us on SF Bay running drills between [Golden Gate Bridge and Treasure Island]. Sorry to hear about ETNZ's wing, broken carbon is never nice," the Kiwi sailor said.
