The first of five new Polish ships built specifically for the Great Lakes-St. Lawrence Seaway trade loaded its first U.S. grain cargo in the Port of Duluth-Superior. Bulk carrier Isa arrived at Duluth's AGP Grain, Ltd., to load about 22,000 tons of spring wheat and feed peas for Barcelona, Spain. Designed and constructed to serve ports in the Great Lakes-St. Lawrence Seaway system, Isa was delivered from a Japanese shipyard in April. Since then, two sister ships have been completed: Isolda in June and Isadora in early August. The fourth new ship is scheduled to enter service in December and the fifth is due in January. All five are owned and managed by the Polish Steamship Co., Szczecin, and represented in North America by Polsteam USA, New York City.
