Yes, that was her first visit. According to duluthshippingnews.com, "The Resko arrived Duluth on Saturday, September 10, 2011 to load grain at the CHS 1 grain terminal in Superior. She departed on the 13th.She is one of several new builds the company has brought to the Great Lakes.Duluth was the end of her maiden voyage that started in China."
As it happens she recently made her second visit to the Lakes; yesterday I had a decent view of her downbound near Montreal.
