Site details

The Lofthus, a 222-ft iron-hulled Norwegian barque built in 1868, wrecked off Manalapan in 1898 while carrying lumber from Pensacola to Buenos Aires. The scattered iron hull now lies in 15-20 ft of water about 175 yards offshore, three-quarters of a mile north of Boynton Inlet, and was designated Florida's eighth Underwater Archaeological Preserve in 2004 and listed on the National Register of Historic Places. Sand movement alternately exposes and buries the wreckage, which shelters lobster, grunts, porkfish and rays.
