In a statement from Team Artemis Racing, it was confirmed that Andrew "Bart" Simpson was killed after his boat capsized during training exercises in San Francisco Bay.

It is with immense sadness that Artemis Racing confirms the tragic death of crewmember Andrew "Bart" Simpson today in San Francisco.

Simpson, a British double Olympic gold medalist, was one of the 11-man crew aboard Artemis Racing's AC72 catamaran which capsized during training on San Francisco Bay ahead of this summer's America's Cup. All other crewmembers are accounted for.

Simpson, however, was trapped underneath the boat and despite attempts to revive him, by doctors afloat and subsequently ashore, his life was lost.

"The entire Artemis Racing team is devastated by what happened," said CEO Paul Cayard. "Our heartfelt condolences are with Andrew's wife and family."
