The Coast Guard says one sailor is dead and four are missing after their yacht ran aground off San Francisco.

Eight people were aboard the 38-foot sailing vessel when it went aground during a race near the Farallon Islands Saturday.

Coast Guard says helicopters and boats rescued three people and recovered the body of a fourth, but four others were still missing and a search was under way late Saturday night.

The yacht was taking part in a race around the islands, located about 30 miles west of San Francisco.
