America's Cup officials pressed on Saturday with their probe of the capsizing of a catamaran that killed Briton Andrew Simpson, seeking answers to keep the world sailing's most prestigious event afloat.

Artemis Racing member Simpson, nicknamed "Bart," died when the Swedish team's AC72 overturned while training on San Francisco Bay on Thursday.

The accident has plunged the Cup into uncertainty, fueling concerns over the safety of the 72-foot America's Cup catamarans and prompting Patrizio Bertelli, chief executive of the Prada fashion house and sponsor of Italian challenger Luna Rossa, to say he would consider pulling out his team.
