Mexico's navy located the boat of a missing American sailor off the country's southern coast, but the Maryland man who had been piloting it solo wasn't found, authorities said Friday.

Donald Lawson's capsized trimaran was found Thursday night by a patrol boat involved in the search 356 nautical miles southwest of the resort city of Acapulco, according to the navy's press office.

The navy said that it would continue its search for Lawson, 41, an experienced sailor.
