A relative of one of four crew members killed in April's Newport-to-Ensenada race on Wednesday called preliminary findings that the sailboat ran aground premature.
Anna Mavromati, daughter of Aegean skipper Theo Mavromatis, said US Sailing — the sport's official governing body — relied too heavily on her father's sometimes inaccurate GPS device in reaching its conclusions that the 37-foot vessel struck North Coronado Island, about 15 miles south of San Diego Bay.
"We know that device isn't entirely accurate," she said. "It usually is, but it's done some strange things before."
An early theory about the wreck was that the Aegean was hit by a freighter in one of the area's busy shipping lanes.
US Sailing expects to release a more complete report in late July.
