A bulk carrier or bulker is a merchant ship specially designed to transport unpackaged bulk cargo—such as grain, coal, ore, steel coils, and cement—in its cargo holds. Since the first specialized bulk carrier was built in 1852, economic forces have led to increased size and sophistication of these ships. Today's bulk carriers are specially designed to maximize capacity, safety, efficiency, and durability.
Lake freighters, or lakers, are bulk carriers operating on the Great Lakes of North America. These vessels are traditionally called boats, although classified as ships. Freighters typically have a long, narrow hull, a raised pilothouse, and the engine located at the rear of the ship.

The SS St. Marys Challenger is a freight-carrying vessel operating on the North American Great Lakes built in 1906. Originally an ore boat, she spent most of her career as a cement carrier when much larger ore boats became common. After a 107-year-long working career as a self-propelled boat, she was converted into a barge and paired with the tug Prentiss Brown as an articulated tug-barge. Before conversion, she was the oldest operating self-propelled lake freighter on the Great Lakes, as well as being one of the last freight-carrying vessels on the Great Lakes to be powered by steam engines.
Algoma Navigator was a Canadian bulk carrier operated by Algoma Central. Like other bulk carriers, her potential cargoes included: coal/coke, aggregates, slag, iron ore/oxides, salt, fertilizers, grain products, gypsum, quartzite, or sand.

The Type L6 ship is a United States Maritime Administration (MARAD) designation for World War II as a Great Lakes dry break bulk cargo ship. The L-Type Great Lakes Dry Bulk Cargo Ships were built in 1943 to carry much-needed iron ore from the upper Great Lakes to the steel and iron production facilities on Lakes Erie and Ontario in support of the war effort. The ships have a 15,675 tonne deadweight tonnage. The L6 ships were built by two companies: American Ship Building Company, in the case of the type L6-S-A1 models, of which 6 were built; and Great Lakes Engineering Works, Ashtabula, Ohio/ Great Lakes Engineering Works, River Rouge, Michigan, in the case of the type L6-S-B1, which produced 10 ships. Steel supply needed for World War was great. To supply iron ore from Lake Superior to steel foundries, the United States Commission had a series of L6 Lakers ship built. The Maritime Commission ordered ten Great Lakes Bulk Carriers of the L6-S-B1 type. The L6-S-B1 was design with a 3-cylinder triple expansion steam engines. The L6-S-A1 used a lentz 4-cylinder compound engine. All L6 ships were coal burning and delivered between May and November 1943. L6-S-B1 was built for the US Maritime Commission under USMC contract MCc-1834 in 1943 at the River Rouge yard. Each L6 ship cost $2.265 million. The first L6-S-B1 was the SS Adirondack/Richard J.

Benson Ford remains famous for: being the first prominent person in the Ford family to actively preach religious harmony between faiths through his NCCJ co-chairmanship ; through the internationally famous Benson Ford Research Center in Dearborn, Michigan, which bears his name; and the now historic 1924 Great Lakes freighter Benson Ford Ship named after him, now known as the Benson Ford Shiphouse, in Put-In-Bay, Ohio. Benson was also noteworthy as being the one member of the Ford family most closely associated with Lincoln-Mercury, rather than Ford, where under Benson's guidance the experimental Lincoln Futura car was developed. The Futura later became the most famous and recognizable car in the world for several years, television's Batmobile driven by Batman actor Adam West.
