Lake freighters, or Lakers, are cargo vessels that ply the Great Lakes. The most well-known is the SS Edmund Fitzgerald, the latest major vessel to be wrecked on the Lakes. These vessels are traditionally called boats, not ships. In the mid-20th century, 300 lakers worked the Lakes but by the early 21st century, there were fewer than 140 active lakers. Visiting ocean-going vessels are called "salties." Due to their additional beam, very large salties are never seen inland of the Saint Lawrence Seaway. Because the largest of the Soo Locks is larger than any Seaway lock, salties that can pass through the Seaway may travel anywhere in the Great Lakes. Because of their deeper draft, salties may accept partial loads on the Great Lakes, "topping off" when they have exited the Seaway. Similarly, the largest Lakers are confined to the Upper Lakes (Superior, Michigan, Huron, Erie) because they are too large to use the Seaway locks, beginning at the Welland Canal that bypasses the Niagara River. Depending on their application, lakers may also be referred to by their type, such as oreboats (primarily for iron ore), Straight Deckers (no self-unloading gear), bulkers (carry bulk cargo), sternenders (all cabins aft), self unloaders (with self unloading gear), longboats (due to their slender appearance), or lakeboats, among others. CargoA modern laker, Earl W. (now Manitowoc), passes the Renaissance Center in Detroit, MI. The most common cargoes on the Great Lakes are taconite, a type of iron ore; limestone; grain; salt; coal; cement; gypsum; sand; slag; and potash. Much of the cargo supplies the steel mills of the auto industry, centered around the Great Lakes because of the ease of transport. Other destinations include coal-fired power plants and stone docks, where limestone is unloaded for the construction industry. SizeThe largest vessels on the lake are the 1000 footers (300 m). These vessels are between 1000 and 1013.5 feet (305 and 309 m) long, 105 feet (32 m) wide and of 56 feet (17 m) hull depth. They can carry as much 78,850 long tons of bulk cargo although their loading is dependent on lake water levels especially in the channels and ports. A dozen of these giant ships were built, all constructed between 1976 and 1981, and all are still in service today. The most powerful of these, the Edwin H. Gott , carries two Enterprise DMRV-16-4 diesel engines driving twin propellers and is rated at 19,500 brake horsepower, making the Gott the most powerful lake boat on the seaway. (14.5 MW). This allows a top speed of 16.7 mph (27 km/h). The Paul R. Tregurtha is the largest boat on the lakes, at 1013'6" and 68,000 gross ton capacity. The Stewart J. Cort, which is not only the first 1000-footer to be put into service on the Lakes, but also the only one built in the traditional wheelhouse-forward Great Lakes style (although all accommodations are forward, and the stern deckhouse is occupied by self unloading equipment and the engines), is another notable vessel. The Cort started life in Mississippi, and was sailed as a much smaller vessel consisting of only the bow and stern sections (appropriately nicknamed "Stubby"), to Erie, Pennsylvania , where she was cut in half and an additional 800+ feet of hull were added. Another interesting 1000-footer is the Presque Isle, an integrated tug and barge combination. The Presque Isle is the largest tug / barge composite in the world. All of the 1000-footers are United States vessels. The Canadian fleet needs to travel to and from its major cities along the St. Lawrence Seaway so the standard length for the Canadian vessels is around 730 feet (Seawaymax-size). The reason for this standard length, is the Welland Canal which bypasses Niagara Falls. The locks here are only about long, and for safety reasons, the vessels must be at most .More common are lake boats in the 600 and 700 foot (183 and 213 m) classes, due to the limitations of the Welland Canal. These vessels vary greatly in configuration and cargo capacity, being capable of hauling between 10,000 and 40,000 tons per trip depending on the individual boat. The latest major vessel built for bulk cargoes on the lakes is the articulated tug/barge combo Samuel De Champlain/Innovation. The barge Innovation and the tug Samuel de Champlain entered service in 2006 hauling cement for LaFarge, operated by Andrie, Inc. List of 1000-footers on the Lakes
DesignBecause these vessels must traverse the locks of the Great Lakes Waterway, they all have features in common, and their appearance differs from similarly sized ocean-going freighters. For instance, they are narrower and generally longer. An early variation of the type (designed by Alexander McDougall and built from 1887 through 1898) was the "whaleback" design, which featured significant tumblehome in the sides of the hull and a rounded bow, looking rather like the back of a whale (hence the name). Where the superstructure of an ordinary freighter used to have the bridge in the center of the vessel, lake freighters typically have the bridge and associated superstructure on the bow. Traditionally they had a second island, over the engine room in the stern. These dual cabined boats were constructed between 1869 and 1974. The R.J. Hackett premiered the style and the second Algosoo was the final vessel designed this way. More recently built lakers, like the CSL Niagara, have a single large superstructure island right astern.A Lake freighter just leaving the Soo Locks (bottom right). Michigan on right foreground, Ontario left and background. Another distinguishing feature of Lake vessels versus Ocean vessels is the cargo hatch configuration. On the Lake vessels, the hatches are traditionally spaced 24 feet (7.8m) apart. This configuration was needed to match the hatches to the loading facilities. At the turn of the 19th century, most ore loading facilities had loading chutes spaced every 12 feet (3.8m). The ship designers used this pattern for their hatch configuration. This pattern continues today, even with modern Lake vessels. A Lake vessel has many more hatches than an Ocean vessel of equal length. The largest deep lock at the Soo is the Poe Lock which is 1,200 feet (370 m) long and 110 feet (34 m) wide. Because of size restrictions, thirty vessels on the lakes can only pass between Lake Superior and Lake Huron using the Poe lock although none approaches the lock's size. Many Lakers are restricted to the Lakes, being unable to navigate the St Lawrence Seaway whose locks allow a maximum vessel size of 740 feet (226 m) in length or 78 feet (24 m) in breadth. The shallow draft imposed by the rivers (typically dredged to about 28 feet (8.5m) by the United States Army Corps of Engineers) restricts the cargo capacity of Lakers, but that is partially recovered by their extra length and box design. Since Great Lakes waves never achieve the great length or period of ocean waves, particularly compared to the waves' height, ships are in less danger of being suspended between two waves and breaking, so the ratio between the ship's length, beam and its depth can be a bit larger than that of an ocean-going ship. The Lake vessels generally have a 10:1 length to beam ratio, whereas the Ocean Vessels are typically 7:1. The dimension of locks is the determining factor in Lake vessel construction.

Iglehart (right) in her last month of a 70-year sailing career, which included surviving a U-boat attack in the Atlantic during World War II. Ship losses and accidentsThe Great Lakes have a long history of shipwreck, groundings, storms and collisions. From the 1679 sinking of Le Griffon with its cargo of furs to the 1975 loss of the Edmund Fitzgerald, thousands of ships and thousands of lives have been lost; many of these losses involved vessels in the cargo trade. The Great Lakes Shipwreck Museum uses the approximate figures of 6,000 ships and 30,000 lives lost. David D. Swayze has compiled a list which details over 4,750 well-documented shipwrecks, mostly of commercial vessels and a list of known names of over 5,000 victims of those sinkings.Maritime historian Mark Thompson reports that based on nautical records, nearly 6,000 shipwrecks on the Great Lakes occurred between 1878 and 1994, with about a quarter of those being listed as total losses with a total of 1,166 lives lost., 17, 18.The most recent losses of modern lakers were (with their causes):
The salties Prins Willem V and Monrovia also sank in the Great Lakes during the 1950s; both in collisions with other ships. Ships on the Lakes have been involved in many lesser incidents. Lakers have been subject to frequent groundings in port and canals due to varying lake levels and silting, collisions with objects (such as the 1993 collision of the Indiana Harbor with the Lansing Shoal Lighthouse), icing in during winter trips and shipboard fires (including the unusual case in 2001 where a drawbridge ran into the Canadian grain carrier Windoc causing a fire). To prevent collisions and groundings, the Great Lakes are well-served with lighthouses and lights, floating navigation aids, and LORAN stations. The U.S. Coast Guard and Canadian Coast Guard maintain stations around the Great Lakes including icebreakers and rescue helicopters. The U.S. Army Corps of Engineers and other agencies maintain the harbors and seaways to limit groundings by dredging and seawalling. November is the traditional last month of shipping before the winter layup (and lake freeze-up). This month sees much of the worst weather of the navigation season and has seen a disproportionate number of accidents. Dana Bowen mentions that one-third of all vessel lost to foundering between 1900-1950 were lost during November and also that over half of all strandings in that time period occurred in November. Famous boatsthumb|250px|Edward L. RyersonThe most famous laker was the SS Edmund Fitzgerald (popularized by Gordon Lightfoot's song "The Wreck of the Edmund Fitzgerald" in 1976), which sank on Lake Superior on November 10, 1975. The Fitz was the first boat with a length of and the flagship of the Columbia Steamship Division of Oglebay Norton Co. The MV Stewart J Cort was the first of the oreboats. The first laker with self-unloading equipment was the Hennepin (formerly the George H Dyer) a small wooden laker that was refitted with the equipment in 1902. The first laker built as a self-unloader was the Wyandotte launched in 1908. Before these, all boats were unloaded with shoreside equipment. Self-unloading equipment worked well for cargoes that could "flow" out of the holds onto belts, such as coal and limestone. It did not work well for grain, which flowed too readily and would spill off the conveyors, or iron ore, which wouldn't flow well and would hang up in the hold. Because the predominant cargo for lakers was iron ore, self-unloaders did not become common until higher grade ores were depleted and taconite pellets were developed in the 1970s. Steam power first appeared in the 1860s and became the standard source of power for over a century. The Canadian grainboat Feux Follets of 1966 was the last laker to be built with a steam turbine and thus was the last steamer built on the lakes. Ford Motor Company's Henry Ford 2nd and Benson Ford of 1925 were the first lakeboats with diesel engines. Diesel powerplants did not become standard until the 1970s. The last active ships of 1920s vintage, and the oldest ships still operating in non-specialized bulk trades is the motor vessels Maumee of Lower Lakes Transportation. She was built as the William G Clyde for US Steel. The ST Crapo, inactive since 1996, was built to haul cement for Huron Cement Co. back in 1927 and was the second ship of that design, the first being the John G Boardman of the same company. The Crapo was the last coal burning freighter on the Great Lakes. The classic design of cabins fore-and-aft with open decks over the hold started with the long R.J. Hackett, designed and built by Elihu Peck in 1869. The first iron-hulled laker was the Brunswick, launched at Detroit in 1881. The Brunswick sank after a collision later that year and was apparently little known. Many follow the lead of the contemporary Cleveland press and credit the Onoko as the first iron-hulled laker, launched in 1882. The Onoko’s higher center section did become a standard for later lakers. At , the Onoko was the first bulk carrier to hold the unofficial title of “Queen of the Lakes” (longest vessel on the lakes). The SS Carl D. Bradley (1927 – 640 feet) held the title for 22 years, longer than any other laker of the classic design. Currently that title is held by the modern stern-ender Paul R Tregurtha. Launched in 1981 as the William J Delancy, and measuring , the Paul R Tregurtha has held the title for 25 years. The Bradley is also known for breaking her back and foundering in a Lake Michigan storm in 1958. There were only two survivors. The Wilfred Sykes (1949 – 678 feet) is considered to be the first of the modern lakers, and when converted to a self-unloader in 1975 was the first to have the equipment mounted aft. Since then all self-unloading equipment has been mounted aft. The Algoisle (formerly the Silver Isle) (1962 – 715.9 feet) was the first modern laker built with all cabins aft (a “stern-ender”), following the lead of ocean-going bulk carriers and reprising a century old form used by little river steam barges and the whalebacks. The Stewart Cort (1971) was the first 1,000 footer and the only “footer” built in the classic cabins-fore-and-aft style. The Algosoo (1974 – 730 feet) was the last laker built in the classic style. Also of note is the steamer Edward L. Ryerson, widely known for her artistic design and being the only remaining straight-decked (without self unloading machinery) freighter still in active service on the U.S. side of the Great Lakes (the only other U.S. straight decker still listed in semi-active service, the John Sherwin, has not sailed since 1981 and is currently docked in Sturgeon Bay, Wisconsin after conversion to a self unloader and repowering was halted in November 2008). In the summer of 2006, the Ryerson was fitted out and put into service following a long-term lay-up that began in 1998. The Ryerson has been meticulously maintained, and was often used as a museum boat for tours. She was put back into service due to a lack of reliable hulls on the Lakes, and a need for more tonnage. (The Canadian fleet retains a number of active straight-deckers for use in transporting grain, which is not well suited for self-unloading equipment. Most US grain is currently transported by rail.) In film, the W.W. Holloway (since scrapped) is famous for being the lake freighter that the Blues Brothers jump their 1974 Dodge over when Elwood jumps the open 95th Street Draw Bridge. Museum ships and boatsClevelandThe William G. Mather, a laker built in 1925 and a former flagship for the Cleveland-Cliffs Iron Company, has been turned into a maritime museum and is open to the public in Cleveland, Ohio in the North Coast Harbor.thumb|right|250px|MV Maumee, one of the oldest active bulk freighters on the Lakes, unloads in Holland, Michigan. Duluth-SuperiorThe William A Irvin was named for the president of U.S. Steel at the time of her launching and served as the flagship of US Steel's Great Lakes fleet from her launch in 1938 to 1975. She was the first laker to incorporate welding in her design and is open for tours at the Great Lakes Floating Maritime Museum in Duluth, Minnesota. Moored nearby is the former USCGC Sundew, a former Coast Guard buoy tender commissioned in 1944. Another museum ship, the , is the last surviving ship of the whaleback design, and is a museum in Superior, Wisconsin, which was the location of the American Steel Barge Company, where the whalebacks were built.ManisteeThe City of Milwaukee, a railroad ferry of the Grand Trunk Milwaukee Car Ferry Company. Built in 1931 to replace a previous ferry, the SS Milwaukee, lost in 1929 with all hands. She sailed for this company for 40 years and another 5 for the Ann Arbor Railroad before laying up in Frankfort in 1982. She sat there until being sold for a museum. Later moved to her present berth in Manistee, she is open for tours as the last unmodified classic railroad ferry. (The older paddlewheel steam railroad ferries Lansdowne, built in 1884, was modified to support a restaurant in antique railcars in Erie, Pa; and the Huron, built in 1875, was stripped of her cabins and sank at a pier in Detroit. The hull of the Landowne was raised and towed to Buffalo. The mayor and daily newspaper have inveighed against the Lansdowne, calling it an eyesore. She has since been scrapped.Manitoulin IslandThe SS Norisle is a museum ship berthed permanently at the Manitowaning Heritage Complex. She is one of three surviving running mates, the others being the Norgoma and the Normac. She was built in 1946, the first ship built in post-WW II Canada, using engines intended for a Royal Canadian destroyer. Norisle ran until 1974 when she was replaced by the MS Chi-Cheemaun. Plans call for sinking the Norisle as a tourist dive site. A group, Friends of The Norisle, some 200 strong, has formed to lobby against this loss of history.MuskegonThe Milwaukee Clipper, another passenger steamer. Built in 1904, she served as a passenger/package freighter for the Pennsylvania Railroad marine division called the Anchor Line as the Stmr. Juniata. In 1940, after several years in layup, she was sold and converted to an excursion steamer between Muskegon & Milwaukee. Laid up in the 1970s, she lingered for 30 years before returning to Muskegon as a museum. Also in Muskegon is the USCGC McLane, a 1920s vintage Coast Guard cutter used to combat the rum-runners in Detroit during Prohibition. Additionally, the USS LST 393, a World War II tank landing ship launched in 1943, is available for tours at West Michigan Dock & Market in downtown Muskegon. Sporting the camouflage livery she wore at the end of the war, the ship worked as an automobile ferry between 1947 and 1973, under the name "M/V Highway 16" (after US Route 16 which was bridged by the ship between Muskegon and Milwaukee, WI).SaugatuckThe SS Keewatin, a former Canadian Pacific passenger liner. Built in Scotland in 1907, the boat steamed between Fort William, Ontario and Port McNicoll for over 50 years until being sold for scrap in 1967. Saved from the wrecker's torch, the Keewatin was towed to Saugatuck, Michigan use as a museum in 1968. She is the last unmodified Great Lakes passenger liner in existence and a wonderful example of Edwardian luxury. Keewatin is one of the world's last coal-fired steamships. A Toronto Star article (June 24-07) documents a Canadian effort to see the venerable steamer returned to Dominion waters as a museum ship at Port McNicoll.Sault Ste. Marie, MichiganThe Valley Camp was built in 1917 and served the National Steel Corporation, the Republic Steel Corporation, and Wilson Transit Co. during her 1917-1966 working life. She became a museum ship on the waterfront of the 'American Soo', east of the Soo Locks, in 1968. She holds many relics of the sinking of the SS Edmund Fitzgerald including one of the Fitz's mauled lifeboats.Sault Ste. Marie, ONThe MS Norgoma, berthed in the Canadian Soo, was built as a steamer carrying freight and passengers in 1950. She ran from Owen Sound to Sault Ste. Marie from 1950 to 1963 on the so-called Turkey Trail. In 1963, the Norgoma was converted to a car ferry, her former role taken over by trucks, buses and automobiles. She ran between Tobermory to Manitoulin Island. At this time, the Norgoma was converted to diesel power. She became a museum ship in 1980. See: http://www.norgoma.org/history.htmlToledoThe Willis B Boyer is another Cleveland-Cliffs Iron Company vessel that sailed from 1911 to 1980. She was originally owned by the Shenango Furnace Company, and was named the Colonel James M. Schoonmaker. She is open to the public as a museum in Toledo, Ohio.Failed museum attemptsSeveral other lakers almost became museums, but due to funding, political opposition or other causes, were sent to the scrapyard.
