Some seven degrees of latitude north of 42N country, the Paul R. Tregurtha makes her way out of Duluth Harbor on June 23rd under the aerial lift bridge. The lake freighter is the longest vessel on the Great Lakes measuring in at 1,013’ 06” - that's 3.37 football fields long! On this day the harbor horn sounded indicating the bridge lifting. That event was followed by the sighting of the departing vessel by people near the canal wall. Within minutes the stupidly-long ship silently glided past the crowd and onto Lake Superior.
