DULUTH, Minn. – A retired Army Corps of Engineers tugboat, still wearing Corps colors, is sinking in Duluth harbor. Why? How? Nobody knows. What to do with it? Because boat’s slowly filling with water, which freezes solid at night,  it’s way too heavy to hoist and place on a barge to haul away. the U.S. Coast Guard has asked  its Marine Safety Unit to assess the situation for fuel leaks and other contaminants – and some ideas on what to do.
