Just a couple of days after seeing Team New Zealand lose control of their boat, America's Cup holders Oracle Team USA have had a heart-stopping moment on the waters of Bermuda while out testing.

Team USA were running through some training at the same time the America's Cup qualifying semifinals were taking place on Friday (NZT).

A video posted by tactician Tom Slingsby on Instagram showed the Team USA boat crashing heavily into the water after attempting a move while low on foiling power.

"Ever wondered what it looks like when we run out of oil to control the foils?" Slingsby posted.



"We had a good crash today testing "how low can you go" in regards to hydro pressure. We found the limit."

The crash down comes two days after Team New Zealand pitch-poled into the Great Sound before capsizing in dramatic scenes before race five against BAR.

That left the team in a rush to repair, something they did as they pulled off their semifinal win over Team Ben Ainslie Racing.

Team New Zealand will race either Dean Barker's Team Japan or Swedish team Artemis for a spot in the America's Cup. That semifinal will be decided on Saturday.
