Investigators asked teams to temporarily stop practicing for the America's Cup on San Francisco Bay in wake of the accident on May 9 that killed a sailor.

Public concern over the safety of racing conditions has grown since British champion sailor, Andrew Simpson, a member of Swedish challenger Artemis Racing, died last week after an ultra-fast catamaran built for racing capsized last week.

A committee formed by organizers met on Thursday to review the fatal accident. After the meeting, the committee asked teams to halt sailing both the 72-foot America's Cup catamarans and the smaller AC45s until the middle of next week.

Organizers said races are on for July.

Teams in the America's Cup are required to stay within rules governing the design of their yachts but they also have leeway to customize their vessels with hydrofoils and other technology.

Investigators plan to look at the structure of Artemis' Big Red yacht, which Regatta Director Iain Murray said differed significantly from other competitors' yachts.

The death of two-time Olympic medalist Andrew Simpson, 36, marked the second time that an expert crew on one of the high-tech yachts, estimated to cost around $8 million each, lost control and flipped their boat in San Francisco Bay.

Simpson, who was training for the America's Cup in September, was trapped underwater for 10 minutes after the Artemis catamaran turned upside down and fell apart during training. Winds were blowing at 23 to 25 miles per hour, at the time of the accident. Race organizers said the blustery winds as typical for the bay.

Following Simpson's death, Artemis Racing pledged to "conduct a thorough analysis and review of this accident" and look at what could be done to limit risks.

On Thursday, crew mates from Artemis and the three other teams scheduled to play in the 2013 America's Cup threw wreaths into the bay where Simpson was killed.
