Career

Martin Mullen made frequent trips to and from Duluth-area ports. She was purchased by Paterson Steamships in 1947 and renamed Scotiadoc.

Final voyage

Scotiadoc was rammed by Canadian steamer Burlington in heavy fog on June 20, 1953, off Trowbridge Island, near the Sleeping Giant in Lake Superior. One crew member died. Captain George Edgar Morris testified that he picked up Burlington on radar when she was 5 nautical miles (9.3 km; 5.8 mi) away. Burlington collided with the starboard side of Scotiadoc near the stern.^[2]

Discovery of shipwreck

Shipwreck hunters found the wreck in 2013. At a depth of 850 feet (259 m), it is the deepest shipwreck in the Great Lakes.^[2][3][4]
