Underwater explorers discovered a 144-year-old shipwreck in Lake Ontario, off Oswego, New York. The ship has been identified as a rare sailing vessel, a scow-sloop, called the Black Duck.

The ship was discovered three years ago while using side-scan sonar. Now, the 51-foot-long, single-mast ship known as a scow-sloop, was identified as The Black Duck. It sank during a gale while hauling goods along the lake’s eastern end in August 1872. The ship’s captain, his wife and a crewmember, the only people on board, all survived by getting into a small boat and reaching shore eight hours later. A search of nautical records turned up only about a dozen references to scow-sloops being built in the region but only a few scow-sloops sailed the Great Lakes. The Black Duck wreck is believed to be the only fully intact scow-sloop to exist in the Great Lakes.
