|It is good for the port when a boat brings cargo into the port and then loads other cargo before departing. Among other things, it makes it cheaper to do business with Duluth Superior if your ship is never empty. The Flinterspirit came in on Monday evening with a crane in its cargo holds and it should be leaving today with grain in its holds. Above, one of the 69 parts of the crane the Flinterspirit brought to Duluth is being lifted out of a Flinterspirit hold at the Port Terminal on Monday. Today, those holds are filled with wheat.
