This large tugboat was built in 1942 by the U.S. Coast Guard in Baltimore, MD as the icebreaker USCGC Manitou WYT-60. In 1984 she was sold civilian to Malcolm Marine of St. Clair, MI, who renamed the tug Manitou and brought her into the Great Lakes. She was laid up until 1996, when she was completely rebuilt and repowered.
Manitou is one of the busier tugs on the Great Lakes, and works in dredging projects, lake towing, icebreaking, and ship assist all across the Great Lakes.
