Lake freighters, or lakers, are bulk carrier vessels operating on the Great Lakes of North America. These vessels are traditionally called boats, although classified as ships. [1] [2] Freighters typically have a long, narrow hull, a raised pilothouse, and the engine located at the rear of the ship.
Lakers have been used since the late 19th century to haul raw material from docks in the upper Great Lakes region to the industrial centers of the Midwest. The navigation season typically begins in late March and ends mid-January due to the formation of ice on the lakes. [3]
SS Edmund Fitzgerald, which sank in 1975, became widely known as the largest and most recent major vessel to be wrecked on the Great Lakes.
The development of the lake freighter's recognizable silhouette was the product of many years of innovation in Great Lakes shipping. Changes in the design were driven by economic and environmental factors, as well as the design advantages of both steamships and sailing ships.
The falls of the St. Marys River forced ships to portage their cargo 1.25 miles (2.01 km) around the falls. In an effort to make shipping more efficient and profitable, Michigan representatives appealed to the federal government for funding to build a canal. In 1855, the Michigan State Locks (now Soo Locks) opened, allowing vessels to keep up with demands for iron ore from further east. This would fuel the development of bulk carriers on the Great Lakes. [5]
By the late 1860s, most bulk cargo was still being carried by unpowered barges and sailing ships. Often, these ships had accessible deck hatches, useful for loading and unloading cargo. Around this time, passenger steamboats were gaining popularity for their faster and more reliable shipping abilities. Though sailing ships would remain more popular for bulk carrying until the widespread adoption of the recognizable lake freighter design. [6]
In 1869, the first modern lake freighter was launched. The wood-hulled R. J. Hackett had an experimental design that would soon set the standard for subsequent bulk carriers on the Great Lakes. The Hackett featured a raised, forward pilothouse situated on top of a set of cabins, and a boxy hull to maximize cargo capacity. Between the raised forecastle and engine funnel at the stern was a long unbroken deck lined with hatches spaced 24 feet apart (to match the chutes of the gravity ore dock in Marquette, Michigan). [6] [7]
The early lakers often had a wooden hull, or a composite hull of an oak frame wrapped in iron plating. With the depletion of high quality timber near the lakeshore, shipbuilders increasingly moved toward all metal hulls. In 1881 and 1882 the first entirely iron-hulled freighters, Brunswick and Onoko , were launched. Around this time, steel was quickly becoming a standard hull material as a result of the Bessemer process making it more affordable, and the first steel-hulled freighter, the Spokane, was launched in 1886. . Soon both iron and composite hulls were discontinued, while wood was used for smaller vessels into the early 1900s. [5] [6] [8]
An early variation on the lake freighter was the whaleback boat, designed by Alexander McDougall. These had cigar-shaped bodies that barely rose out of the water when fully loaded, and carried bulk cargo on the lakes from 1888 through 1970. [9] [10]
The early lake freighters required cargo to be manually unloaded, or with assistance from unloading machinery at the docks. [11] In 1902, Hennepin was the first ship to be retrofitted with self-unloading equipment, allowing its cargo to be landed in a fraction of the time. [6]
Around 1916, 600-foot vessels more or less became the standard size. [12]
After World War II, several ocean freighters and tankers were transported to the Great Lakes and converted to bulk carriers as a way to acquire ships cheaply. Several of them continue to sail today. The oil tanker USS Chiwawa is now the bulk freighter Lee A. Tregurtha [13] In addition, the freighter Outer Island was originally commissioned as LCT-203 for use as a Landing Craft Tank during World War II. [14]
In the mid-20th century, 300 lakers worked the lakes, but by the early 21st century, there were fewer than 140 active lakers. [15] By the 1990s, older and smaller self-unloaders and straight-deck freighters converted into tug-barges. [16]

The many lake freighters operating on the Great Lakes can be differentiated by how they are used. This may be where the ships may be where they work, their design, their size, or other factors. The ships are not always exclusive to one category. These types include:
Some of the newer classes of lake freighters include:
Iron ore | 42.3 |
Coal | 10.0 |
Limestone | 22.9 |
Cement | 3.4 |
Salt | 0.9 |
Sand | 0.5 |
Grain | 0.3 |
Total | 80.4 |
Source: "Cargo Reports – Year-in-Review 2023 – U.S.-Flag Vessels" [30] |
The most common cargoes on the Great Lakes are taconite, limestone, grain, salt, coal, cement, gypsum, and sand. [31] The cargo is carried in large contiguous holds, not packed into containers.
Much of the cargo supplies the steel mills of the auto industry, centered around the Great Lakes because of the ease of transport.
The 1940s saw the rise in the use of taconite pellets, as sources of higher quality ore diminished. [32]
Other destinations include coal-fired power plants, highway department salt domes, and stone docks, where limestone is unloaded for the construction industry. U.S.-flagged freighters carried the largest portion of the trade, accounting for two-thirds of all cargo by weight. U.S. hulls carried most of the iron, limestone and cement, while Canadian boats carried most of the potash, and almost all of the salt and grain moved on the lakes.[ citation needed ]
Destination harbors, ship sizes, and legal restrictions greatly affect the pattern of haulage. Large U.S. ships hauled most of the iron ore on the lakes (79%) from U.S. mines to U.S. mills. This reflects the requirement of the Jones Act, as well as the industry using large volumes of material while being concentrated in a few large harbor locations. Salt and Canadian grain can be hauled to numerous smaller ports of either country on smaller, mostly Canadian, ships, which can also enter the St. Lawrence Seaway with the Canadian ports of Montreal and Quebec City.[ citation needed ]
Because of their deeper draft and freshwater's lower buoyancy, salties often take on partial loads. [33] Conversely, the Seaway allows smaller lakers to access the Atlantic Ocean. The larger, newer ships are restricted to the upper lakes.
The size of a lake freighter determines where it can work. The shallow draft imposed by the St. Marys River and Lake St. Clair restrict the cargo capacity of lakers.[ citation needed ] Poe Lock at the Soo Locks is the largest deep lock at 1,200 feet (370 m) long and 110 feet (34 m) wide. [34]
Many of the lakers are unable to navigate the locks of the St. Lawrence Seaway that restricts vessel size to 740 feet (230 m) in length and 78 feet (24 m) in breadth. [35] Seawaymax vessels are able to access the Great Lakes and the ocean. The Canadian fleet needs to travel to and from its major cities along the St. Lawrence Seaway, so the largest length for the Canadian vessels is 740 feet (230 m).[ citation needed ]
Lake boats in the 600-and-700-foot (180 and 210 m) classes are more common, because of 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. These smaller boats serve smaller harbors around the lakes which have irregular need for their services.
Another reason for the lack of larger Canadian vessels is legislative in nature. Larger ships on the lakes are generally used to transport American-mined ore bound for American mills. Because of the Jones Act of 1920, only American ships can carry ore from American mines to American mills in American ports; ergo, larger Canadian ships are not needed.[ citation needed ]
These are the largest vessels on the lakes. A dozen were built between 1976 and 1981, and all remain in service today. These U.S.-flagged vessels and are between 1,000 and 1,013.5 feet (304.8 and 308.9 m) long, 105 feet (32 m) wide and of 56 ft (17 m) hull depth. They can carry as much as 78,850 long tons (80,120 t) of bulk cargo.[ citation needed ]

Lakers feature a design distinct from their ocean-going counterparts. Because of the R. J. Hackett (1869), lake freighters typically had the bridge and associated superstructure at the bow. Additionally, a second island would be located over the engine room in the stern. In 1974, Algosoo was the final vessel designed this way.[ citation needed ]
The more recently built lakers, like CSL Niagara, have a single large superstructure island at the stern.
The largest lake freighters can travel up to 15 knots. [16] Vessel speeds are not as important on the lakes as on the ocean. Ports are often closer together than in ocean trade, so cargo capacity is more important than speed.[ citation needed ]
Lake vessels are designed with the greatest block coefficient to maximize the vessel's size in the locks within the Great Lakes/St Lawrence Seaway system. Therefore, ship designers have favored bluff bows over streamlined bows.[ citation needed ]
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 (7.3 m) apart. This configuration was needed to match the chutes at loading facilities.
Since Great Lakes waves do not 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 larger than that of an ocean-going ship. The lake vessels generally have a 10:1 length to beam ratio, whereas ocean vessels are typically 7:1.[ citation needed ]
Modern lakers are usually designed and constructed for a 45-50 year old service life, outlasting ocean-going bulk carriers. [39] As of 2023, ocean-going bulk freighters average an 11-year lifespan, due in part to the corrosive effects of saltwater. [40] [41]
Some of the lakers have been known to have long careers. The SS St. Marys Challenger launched in 1906 and worked independently until 2013. The Challenger is still in service as a barge at 118 years old. [42] E. M. Ford had one of the longest careers, having been built in 1898 until being sold for scrap in November 2008. [43]
Some shipping companies are building new freighters to ply the waters of the Great Lakes. The following are new freighters in use or will be launched for use in the Great Lakes:
The Great Lakes have a long history of shipwrecks, groundings, storms, and collisions. From the 1679 sinking of Le Griffon with its cargo of furs to the 1975 loss of Edmund Fitzgerald , thousands of ships and thousands of lives have been lost, many involving vessels in the cargo trade. The Great Lakes Shipwreck Museum uses the approximates 6,000 ships and 30,000 lives lost. [45] 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. [46] 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. [47]
The most recent losses of modern lakers were:
The salties Prins Willem V and Monrovia sank in the Great Lakes during the 1950s; both in collisions with other ships. The saltie Francisco Morazan was a total loss after running aground off South Manitou Island on November 29, 1960. Another saltie Nordmeer grounded on Thunder Bay Island Shoal in November 1966, but before it could be refloated, it was further damaged in the same storm that sank the Morrell and was declared a total loss.
Ships on the lakes have been involved in many lesser incidents. Lakers have been subject to frequent groundings in ports and channels because of varying lake levels and silting, collisions with objects (such as the 1993 collision of the Indiana Harbor with the Lansing Shoals Light Station), [47] 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, and floating navigation aids. 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. [49]
November was the traditional last month of shipping before the winter layup (and lake freeze-up). During November, much of the worst weather of the navigation season occurs which has resulted in a disproportionate number of accidents. One study shows that over half of all strandings and one-third of all vessels lost to foundering between 1900–1950 were lost during November. [50]

The most well-known lake freighter was Edmund Fitzgerald, which sank during a storm on Lake Superior on November 10, 1975. Gordon Lightfoot's ballad, "The Wreck of the Edmund Fitzgerald", publicized the incident. [51] The Edmund Fitzgerald became the largest ship on the lakes at 729 feet (222 m) when launched in 1958. In addition to this, the ship was regarded for its "DJ Captain," Peter Pulcer, who frequently played music to entertain onlookers. [52]
SS Arthur M. Anderson. launched in 1952, is known for having last contact with Edmund Fitzgerald and was the first vessel on-scene to search for the Edmund Fitzgerald. [53]
Paul R. Tregurtha currently holds the title "Queen of the Lakes" as the largest ship on the lakes since launching in 1981. The modern stern-ender was first launched William J. Delancy and measures 1013.5 feet (308.9 m). [54]
Onoko was the second iron-hulled laker, launched in 1882. At 302 ft, Onoko was the longest ship on the lakes and became the first bulk carrier to hold the unofficial title of "Queen of the Lakes." The title that has been passed down to record-breaking lake freighters since. SS Carl D. Bradley held the title for 22 years, longer than any other laker of the classic design.[ citation needed ] Ford Motor Company's Henry Ford II and Benson Ford of 1924 were the first lakeboats with diesel engines. [55] The Canadian grainboat Feux Follets of 1967 was the last laker built with a steam turbine on the lakes. S. T. Crapo was the last coal burning freighter on the Great Lakes. [17]
Wilfred Sykes (1949 – 678 ft, 207 m) 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. Algoisle (formerly Silver Isle) (1962 – 715.9 ft, 218.2 m) 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. Algosoo (1974–2015 730 ft, 220 m) was the last laker built in the classic style.[ citation needed ]
Also of note is the steamer Edward L. Ryerson, widely known for her artistic design and being the only remaining straight-decked freighter still in active service on the US side of the Great Lakes.[ citation needed ] In the summer of 2006, Edward L. Ryerson was fitted out and put into service following a long-term lay-up that began in 1998. Ryerson has been in long-term layup since 2009. [56]
The William G. Mather was first built in 1925 and served as the Cleveland-Cliffs Iron Company's flagship until 1980. In 1987, the ship was donated to the Great Lakes Historical Society for restoration and preservation. In 2005, the ship was moved to its present location at Cleveland's North Coast Harbor. Then, in 2006, the ship was acquired by the Great Lakes Science Center for use as a museum ship. The ship is available to tour seasonally. [57] [58]
The William A. Irvin (named for the president of U.S. Steel) served as the flagship of their Great Lakes fleet from 1938 to 1975. The Irvin was retired in 1978 and purchased 8 years later by the Duluth Entertainment Convention Center and is available for touring. [59] [60]
The SS Meteor, the last surviving whaleback ship, floats as a museum less than a mile from where it was launched in Superior, Wisconsin. The ship is permanently land-berthed on Barker's Island. [61]
Valley Camp served from 1917 to 1966. Two years later the ship became a museum on the waterfront of the 'American Soo', east of the Soo Locks, in 1968. She holds many relics of the sinking of Edmund Fitzgerald including two of Edmund Fitzgerald's mauled lifeboats. [62]
The 118-year-old SS St. Mary's Challenger's pilothouse is set to be displayed in the National Museum of the Great Lakes' upcoming museum expansion. [63]
The SS Col. James M. Schoonmaker floats in the Maumee River as a museum ship for the National Museum of the Great Lakes. When launched in 1911, it was the largest bulk freighter in the world. [64] The Schoonmaker had been a floating museum before, after being purchased by the City of Toledo, Ohio in 1987. [65]
Lewis G. Harriman's bow and bow superstructure are preserved as a residence in DeTour, Michigan. The ship was christened as the SS John W. Boardman in 1923. In 1965, the Boardman was renamed to Lewis G. Harriman and used to store cement during the Poe Lock construction in Sault Ste. Marie, Michigan. The ship was sold for scrap 2003, but the pilothouse and hull of the Harriman were saved and now are used as a residence along the lakeshore. [66]
John Sherwin, not sailed since 1981, is currently docked in DeTour, Michigan after conversion to a self-unloader and repowering was halted in November 2008. [67]
The pilothouse of William Clay Ford is part of the Dossin Great Lakes Museum on Belle Isle. [68] The pilot house is open for tours and overlooks the Detroit River.
SS Ridgetown was partially sunk as a breakwater (with stack and cabins intact) near Toronto at Port Credit. It was built in 1905 and is one of the oldest surviving hulls on the lake. Its silhouette provides an example of the appearance of early 1900s lake freighters.
Benson Ford, was the flagship of the Ford Motor Company fleet when launched in 1924. The forward cabin is now located on a cliff on South Bass Island in Lake Erie, where it was moved in 1986. It has been a private residence since 1999. The home is intermittently available to tour. [69] [70]
Several other lakers nearly became museums, but were scrapped for lack of funding, political opposition, and other causes.
A merchant ship, merchant vessel, trading vessel, or merchantman is a watercraft that transports cargo or carries passengers for hire. This is in contrast to pleasure craft, which are used for personal recreation, and naval ships, which are used for military purposes.
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.
SS Arthur M. Anderson is a cargo ship of the laker type. She is famous for being the last ship to be in contact with SS Edmund Fitzgerald before she sank on November 10, 1975. Arthur M. Anderson was also the first rescue ship on the scene in a vain search for Edmund Fitzgerald survivors. The vessel's namesake, Arthur Marvin Anderson, was director of U.S. Steel, a member of its finance committee and vice chairman of J.P. Morgan & Co. at the time. The ship was launched in 1952 and is in active service.
A whaleback was a type of cargo steamship of unusual design, with a hull that continuously curved above the waterline from vertical to horizontal. When fully loaded, only the rounded portion of the hull could be seen above the waterline. With sides curved in towards the ends, it had a spoon bow and a very convex upper deck. It was formerly used on the Great Lakes of Canada and the United States, notably for carrying grain or ore. The sole surviving ship of the "whaleback" design is the SS Meteor, which is docked in Superior, Wisconsin, as a museum ship.
USS Chiwawa (AO-68) is a former T3-S-A1 Kennebec-class oiler constructed for the United States Navy during World War II. She was the only U.S. Navy ship named for the Chiwawa River in Washington.
The Great Lakes Engineering Works (GLEW) was a leading shipbuilding company with a shipyard in Ecorse, Michigan, that operated between 1902 and 1960. Within three years of its formation, it was building fifty percent of the tonnage of all ships in the Great Lakes. During World War II, GLEW was commissioned by Pittsburgh Steamship Company and the U.S. Maritime Commission to build twenty-one ore freighters. Its innovations included the first self-unloader freighter, SS Wyandotte. GLEW is best known for its construction of the SS Edmund Fitzgerald.
MV Paul R. Tregurtha is a Great Lakes-based bulk carrier freighter. She is the current Queen of the Lakes, an unofficial but widely recognized title given to the longest vessel active on the Great Lakes. Launched as MV William J. De Lancey, she was the last of the thirteen "thousand footers" to enter service on the Great Lakes, and was also the last Great Lakes vessel built at the American Ship Building Company yard in Lorain, Ohio. The MV Paul R. Tregurtha is the current flagship for the Interlake Steamship Company.
English River was a lake freighter and bulk carrier, launched in 1961 by Collingwood Shipyards of Collingwood, Ontario. In her initial years she carried bulk cargoes and deck cargoes to smaller ports on the Great Lakes and Saint Lawrence River watershed and estuary. In 1973, the vessel was converted into a cement carrier and carried mainly raw cement for the construction industry. The ship continued to operate until English River was removed from service and sold for scrap.
CSL Tadoussac is a lake freighter currently operated by Canada Steamship Lines (CSL) on the Great Lakes. She was launched in 1969. Initially named Tadoussac, following her refit in 2001, she was renamed CSL Tadoussac She was the last freighter built for CSL in the traditional two superstructure design, which puts her bridge up in the ship's bow. The vessel primarily transports iron ore and coal.
The Interlake Steamship Company is an American freight ship company that operates a fleet on the Great Lakes in North America. It is now part of Interlake Maritime Services.
SS Clifton, originally Samuel Mather, was a whaleback lake freighter built in 1892 for service on the Great Lakes. She was 308 foot (94 m) long, 30 foot (9.1 m) beam, and 24 foot (7.3 m) depth, and had a 3,500 ton capacity. The self-propelled barge was built by the American Steel Barge Company in West Superior, Wisconsin. Her builders used a design well-suited to carry iron ore, her intended trade. The new vessel was christened Samuel Mather, after a cofounder of Pickands Mather and Company, which at the time was the second largest fleet on the Great Lakes.
The Henry Cort was a 320-foot (98 m) long whaleback freighter. It sank four times during its career; finally running aground at Muskegon, Michigan in November, 1934. The ship broke apart over the winter and was scrapped in 1935.
Augustus B. Wolvin was a 560 ft (170 m) long Great Lakes freighter that had a 63-year career on the Great Lakes. Augustus B. Wolvin was a product of the American Shipbuilding Company of Cleveland, Ohio. She was built for the Acme Steamship Company of Duluth, Minnesota.

Algoma Sault, which entered service in 2018, is the third freighter Algoma Central named after Sault Ste. Marie, Ontario. She is a self-unloading bulk carrier, built for carrying cargoes like ore, grain, or coal, on the North American Great Lakes and St. Lawrence Seaway. She is the seventh vessel of the Equinox class, and like her sister ships she was built in China.
The River class is a type of bulk carrier designed for service on the Great Lakes. The MV Mark W. Barker, the first of the class is due to enter service for the Interlake Steamship Company on 27 July 2022.
MV Mark W. Barker is a large diesel-powered lake freighter owned and operated by the Interlake Steamship Company. She is the first of the River-class freighters constructed for an American shipping company. MV Mark W. Barker is the first ship on the Great Lakes to be powered with engines that meet EPA Tier 4 standards. It is the first U.S.-flagged, Jones Act-compliant ship built on the Great Lakes since 1983.
The SS J.L. Mauthe, was originally a straight-deck bulk carrier steamship, hull #298, built in 1952 by the Great Lakes Engineering Works on the River Rogue, Michigan site and delivered to its owner, Interlake Steamship Company. The SS J.L. Mauthe operated as a self-propelled vessel for 46 years. Upon conversion into a barge, it was renamed as Pathfinder and is currently active on the lakes as an articulated tug-barge unit, paired with the tug Dorothy Ann.
