Question 154 Deck General

The correct answer is C) A 500 GT dry cargo river barge operated continuously between Calumet Hbr Chicago, IL and Burns Hbr, IN. This is because vessels operating exclusively on the Great Lakes System, including the St. Lawrence Seaway, are exempt from the load line and marking requirements, as long as they do not navigate on the high seas. The 500 GT dry cargo river barge operating between two ports on the Great Lakes System meets this criteria and is therefore exempt. The other options, while they may involve vessels operating on the Great Lakes, do not meet the criteria for exemption, as they either operate on the St. Lawrence River (which is not part of the Great Lakes System) or do not operate exclusively within the Great Lakes System.
