600 Footers
The 600-footers were a class of lake freighters all built to the design of the ''J. Pierpont Morgan''. The ''J. Pierpont Morgan'' was launched in April, 1906, and was, at the time, the longest vessel on the Great Lakes. Her sister ships were not all identical. Minor modifications were made. Mark L. Thompson, author of '' Queen of the Lakes'', wrote that between 56 and 76 vessels were built to this design. The 600-footers could use harbours that larger seawaymax vessels can't use. Until 1961 no vessel longer than 600 feet was able to access Cleveland's harbour. The vessels' draught was . Their beam was . They were powered by triple expansion steam engines, providing , and could carry 11,000 tons of cargo. They cost $440,000 to construct, in 1906 dollars.

Lake Freighter
Lake freighters, or lakers, are bulk carrier vessels that operate on the Great Lakes of North America. These vessels are traditionally called boats, although classified as ships. Since the late 19th century, lakers have carried bulk cargoes of materials such as limestone, iron ore, grain, coal, or salt from the mines and fields of the upper Great Lakes to the populous industrial areas farther east. The 63 commercial ports handled 173 million tons of cargo in 2006. Because of winter ice on the lakes, the navigation season is not usually year-round. The Soo Locks and Welland Canal close from mid-January to late March, when most boats are laid up for maintenance. Crew members spend these months ashore. Depending on their application, lakers may also be referred to by their types, such as ''oreboats'' or ''ironboats'' (primarily for iron ore), ''straight deckers'' (no self-unloading gear), ''bulkers'' (carry bulk cargo), ''sternenders'' (all cabins aft), ''self unloaders'' (with sel ...
