(SAN FRANCISCO) — A Swedish yacht practicing for the upcoming America’s Cup capsized in San Francisco Bay Thursday, leaving one crew member dead.
The Swedish team Artemis was sailing the catamaran when it overturned between 12:30 p.m. and 1 p.m. local time, according to America’s Cup officials.
Crew members jumped off the boat and swam toward support boats as the racing boat capsized, although officials said they were still not certain why it tipped over.
Coast Guard rescue teams and a helicopter quickly convened and rescued all 12 sailors from the boat, though one crew member was flown to a nearby hospital and later died, firefighters confirmed.
America’s Cup runs from July 4 to Aug. 30.
