A U.S. sailing association says a yacht apparently collided with a much larger vessel during a race off the coasts of California and Mexico, killing three crew members and leaving one missing. The Newport Ocean Sailing Association was hosting the 125-mile Newport, California to Ensenada, Mexico yacht race when the collision occurred several miles off the coast near the border. Association spokesman Rich Roberts says in a news release early Sunday that an investigation is ongoing but it appears that the 37-foot Aegean collided with a much larger ship. The Coast Guard says the search for the missing crew member was continuing early Sunday morning, according to a report of the Associated Press.
