The Newport Ocean Sailing Association was hosting the 125-mile Newport, Calif. 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.
There were no more details on the other vessel.
The Coast Guard says the search for the missing crew member was
continuing early Sunday morning.
