There is also a Great Lakes ship named "Alpena", formerly the "Leon Fraser", owned by Inland Lakes Management, an affiliate of Lafarge. It is used as a bulk freighter to haul cement. Built in 1942 and equipped with a steam turbine engine, it was originally 639 feet long, 67 feet in breadth with a depth of 35 feet. It has a 15,550 ton capacity. It was renamed, shortened and converted to a bulk cement carrier in 1991. The "Alpena" is a moderate sized ship in the Great Lakes fleet; the largest Lakers are almost twice its length and breadth and carry four times its cargo. She is able to transit the canals of the St. Lawrence Seaway due to her small size.
