America's Cup holders Oracle Team USA have had a scary moment in Bermuda today while testing on the water.
Team USA were sailing alone as the America's Cup qualifying semifinals were taking place.
Tactician Tom Slingsby posted a video on Instagram of the Team USA boat crashing heavily into the water after attempting a move while slow on speed.
"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.
Team New Zealand bounced back to get back on the water today and defeat the British team to advance to the qualifying final series. They will race either Dean Barker's Team Japan or Swedish team Artemis for a spot in the America's Cup.
