Site details

The broken remains of an unidentified late-19th-century wooden sailing ship (often attributed to the 1880 barkentine D.H. Bills) lying at the mouth of Delaware Bay roughly 12 miles off Cape Henlopen. The low rubble mound, about 100 ft long and 6-8 ft high in 45-50 ft of water, still yields fragments and occasionally intact pieces of its Victorian-era English china cargo. It is one of the region's classic artifact dives but must be timed to slack tide because bay currents rip across the flat sand bottom.
