Site details

The Champlain II was a 244-ft sidewheel steamer launched in Burlington in 1868 as the Oakes Ames and converted to a passenger vessel in 1874. She ran hard aground near Barn Rock north of Westport, NY on the night of July 16, 1875, and today about 160 ft of her lower hull and machinery debris rest on a sloping bottom in 15-35 ft of water close to the New York shore. The site is a designated underwater historic preserve marked by a yellow mooring buoy with underwater interpretive signage, and free annual diver registration is required.
