SAN FRANCISCO (AFP) - A British double Olympic medalist sailor died Thursday after the catamaran of a Swedish team training for the upcoming America's Cup races capsized on San Francisco Bay, officials said.
The man, identified as Andrew "Bart" Simpson, was trapped under the Artemis Racing boat for about 10 minutes, according to a statement on the America's Cup website, which said emergency crews tried to revive him.
A spokeswoman for the San Francisco Fire Department, Mindy Talmadge, said Simpson was pronounced dead at the St. Francis Yacht Club.
"Our dispatch center was notified... that an Artemis boat had capsized and one person was reportedly in the water 10 or 15 minutes. One of the chase boats pulled the gentleman out of the water and began CPR," Ms Talmadge told AFP.
"Rescue workers continued CPR as the man was transported to the St. Francis Yacht Club, where paramedics were waiting. Unfortunately, they ended up pronouncing him dead at the Saint Francis Yacht Club," she said.
A second crew member suffered injuries not thought to be life threatening, she said. Twelve crew members were on the boat when it capsized and all have been accounted for.
The yacht involved is a AC72 catamaran, the Swedish team's first, according to the online statement, which said the incident occurred between 12.30pm and 1.00 pm (3.30am-4am Singapore time).
The AC72 boats in the America's Cup were described by event organizers as "speedsters" powered by 39.6-metre tall wing sails and with the ability to hydrofoil - essentially rise out of the water to reduce drag.
They can reach top speeds in excess of twice the windspeed, and place strenuous physical demands on crew members.
The catamarans have been adopted for the venerable yachting competition this year in a bid to make the event more exciting.
The Oracle syndicate, owned by software billionaire Larry Ellison, defeated Switzerland's Alinghi in a trimaran to win the last edition of the America's Cup in 2010.
Ellison pushed for the switch to the catamarans as part of an effort to make the event more television-friendly.
The Louis Vuitton Cup to decide a challenger will be held July 4 through September 1. The winner will take on Oracle Racing for the America's Cup from September 7-22.
Oracle Racing's AC72 capsized in spectacular fashion in October on San Francisco Bay, but no one was injured.
Veteran skipper Russell Coutts capsized a similar catamaran in San Francisco Bay in June 2011.
Talmadge said she did not know what sequence of events led to the Artemis Racing craft's capsizing.
The Artemis team was aware of the challenges and dangers in planning their preparations for the competition, and hoped to give their crew members adequate opportunity to learn to handle the AC72.
"Before performance, there is the safety of our team," Artemis CEO Paul Cayard said when they launched their boat in Spain last year. "San Francisco Bay in July and August is an unforgiving place."
