Philippine coast guard chief Adm. Wilfredo Tamayo says a search ship guided by a spotter plane located and boarded the 38-foot (11-meter) catamaran The Pineapple after it was spotted off the southern island of Dinagat. They are escorting the vessel to its original destination on central Cebu island.

The vessel was reported missing on its way to the Philippines after apparently developing engine trouble.

Tamayo says the four men and one woman on board are fine.

Relatives of the Americans alerted the U.S. Coast Guard that The Pineapple left Guam on Jan. 6 but had not reached Cebu.
