The SS Edmund Fitzgerald was an American freighter that sank in Lake Superior during a storm on November 10, 1975, with the loss of all 29 crew members. When it was launched on June 7, 1958, it was the largest ship on the Great Lakes. It is still the largest ship to have sunk there. On November 14, 1975, a U.S. Navy aircraft found the ship in deep water by detecting unusual magnetic signals. Soon after, the ship was discovered in two large pieces.

For 17 years, the Edmund Fitzgerald carried taconite, a type of iron ore, from mines near Duluth, Minnesota, to iron works in Detroit, Michigan; Toledo, Ohio; and other Great Lakes ports. As a strong and reliable ship, it set seasonal haul records six times, often breaking its own records. Captain Peter Pulcer was known for playing music through the ship’s intercom day or night while traveling through the St. Clair and Detroit rivers (between Lake Huron and Lake Erie) and for giving live updates to people watching the ship pass through the Soo Locks (between Lakes Superior and Huron). Its size, record-breaking performance, and friendly captain made the Edmund Fitzgerald a favorite among ship watchers.

On the afternoon of November 9, 1975, the Edmund Fitzgerald began its final trip from Superior, Wisconsin, near Duluth, carrying a full load of taconite ore pellets. Captain Ernest M. McSorley was in charge. The ship was heading to a steel mill near Detroit when it was caught in a severe storm the next day. The storm had winds as strong as those in a hurricane and waves as high as 35 feet (11 meters). Around 5:30 p.m., the Edmund Fitzgerald reported being in trouble. At 7:10 p.m., Captain McSorley sent his final message: “We are holding our own.” Shortly after 7:10 p.m., the ship sank in Canadian (Ontario) waters 530 feet (160 meters) deep, about 17 miles (27 kilometers) from Whitefish Bay near the twin cities of Sault Ste. Marie, Michigan, and Sault Ste. Marie, Ontario. The ship could have reached that location in less than an hour at its fastest speed. All 29 crew members died, and no bodies were recovered. The exact reason the ship sank is still unknown, though many books, studies, and expeditions have examined the event. Possible causes include the ship being swamped by waves, suffering structural damage, hitting a shallow area, or a combination of these issues.

The sinking of the Edmund Fitzgerald is one of the most well-known disasters in Great Lakes shipping history. This is partly because Canadian singer Gordon Lightfoot wrote a popular song about the event called “The Wreck of the Edmund Fitzgerald.” Lightfoot wrote the song after reading an article titled “The Cruelest Month” in the November 24, 1975, issue of Newsweek. The disaster led to changes in Great Lakes shipping rules and practices, including requiring survival suits, depth finders, positioning systems, increased freeboard, and more frequent inspections of ships.

History

Northwestern Mutual Life Insurance Company of Milwaukee, Wisconsin, invested heavily in the iron and minerals industries. They built the Edmund Fitzgerald, which was the first such investment by any American life insurance company. In 1957, they hired Great Lakes Engineering Works (GLEW) of River Rouge, Michigan, to design and build the ship. The ship was made to be just under the maximum length allowed for passage through the Saint Lawrence Seaway, which was being completed at the time. The ship’s value in 1957 was $7 million, which equals about $59.6 million in 2024. Edmund Fitzgerald was the first ship built to the maximum size allowed by the Saint Lawrence Seaway. It was 730 feet long, 75 feet wide, and had a 25-foot draft. The ship’s hull was 39 feet tall, and the cargo hold inside was 33 feet 4 inches tall. GLEW laid the first piece of the ship’s frame on August 7, 1957.

Edmund Fitzgerald was the longest ship on the Great Lakes, with a hull length of 729 feet. It was called the "Queen of the Lakes" until 1959, when a larger ship, the SS Murray Bay, was launched. The ship had three large cargo holds that were loaded through 21 watertight hatches. Each hatch was 11 by 48 feet and made of thick steel. In 1969, the ship’s ability to move easily was improved with the addition of a diesel-powered bow thruster. Originally powered by coal, the ship’s boilers were changed to burn oil during the 1971–72 winter.

Compared to other ore freighters, Edmund Fitzgerald was very comfortable inside. It had deep pile carpets, tiled bathrooms, and drapes over the windows. The guest lounge had leather swivel chairs. There were two rooms for passengers. The crew quarters had air conditioning and more comforts than usual. A large kitchen and pantry provided meals for two dining rooms. The ship’s control room had modern navigation equipment and a map room.

Northwestern Mutual wanted to name the ship after its president and chairman, Edmund Fitzgerald. Fitzgerald’s family had a long history with the Great Lakes, and he tried to stop the ship from being named after him. He suggested names like Centennial, Seaway, Milwaukee, and Northwestern. However, the company’s board voted unanimously to name the ship SS Edmund Fitzgerald. Over 15,000 people attended the ship’s christening on June 7, 1958. The event had problems: the champagne bottle took three tries to break, a guest had a heart attack and died, and the ship’s launch caused delays and a wave that soaked the crowd. The ship completed sea trials on September 22, 1958.

Northwestern Mutual usually bought ships to be operated by other companies. For Edmund Fitzgerald, they signed a 25-year contract with Oglebay Norton Corporation to run the ship. Oglebay Norton made Edmund Fitzgerald the flagship of its Columbia Transportation fleet.

Edmund Fitzgerald set many records. In 1969, it carried 27,402 long tons of cargo in one trip. For 17 years, it transported taconite from Minnesota’s Iron Range to iron works in Detroit, Toledo, and other ports. It set seasonal haul records six times. The ship had many nicknames, including "Fitz," "Pride of the American Flag," "Mighty Fitz," "Toledo Express," "Big Fitz," and the "Titanic of the Great Lakes." Loading the ship with taconite pellets took about four and a half hours, while unloading took 14 hours. A round trip between Superior, Wisconsin, and Detroit, Michigan, took five days, and the ship made about 47 trips each season. Its usual route was between Superior, Wisconsin, and Toledo, Ohio, but it sometimes went to other ports. By November 1975, Edmund Fitzgerald had made about 748 round trips on the Great Lakes and traveled more than a million miles, which is about 44 trips around the world.

Until a few weeks before it sank, passengers were invited on board as guests. Stewards provided VIP treatment, including excellent food and snacks. The captain held a candlelight dinner for guests once per trip.

Because of its size, achievements, and unique captain, Edmund Fitzgerald became a favorite among boat watchers. Captain Peter Pulcer was known for playing music over the ship’s intercom and giving tours to tourists through the Soo Locks.

In 1969, Edmund Fitzgerald won a safety award for eight years without any worker injuries. The ship had several accidents, including running aground in 1969 and colliding with another ship in 1970. It also hit a lock wall in 1970, 1973, and 1974. In 1974, it lost its original bow anchor in the Detroit River. These incidents were not serious. Freshwater ships like Edmund Fitzgerald are built to last over 50 years, and it would have had a long future if it had not sunk.

Final voyage and wreck

Ernest M. McSorley (September 29, 1912 – November 10, 1975) was the final captain of the SS Edmund Fitzgerald. He died with the other 28 crew members on November 10, 1975. The Edmund Fitzgerald left Superior, Wisconsin, at 2:15 p.m. on November 9, 1975, under McSorley’s command. The ship was traveling to a steel mill on Zug Island, near Detroit, carrying 26,116 long tons (29,250 short tons; 26,535 t) of taconite ore pellets. It reached its top speed of 16.3 miles per hour (14.2 kn; 26.2 km/h). Around 5 p.m., the Edmund Fitzgerald joined another ship, the Arthur M. Anderson, which was heading to Gary, Indiana, from Two Harbors, Minnesota. The National Weather Service (NWS) predicted a storm would pass south of Lake Superior by 7 a.m. on November 10.

The SS Wilfred Sykes left the Burlington Northern Dock #1 at 4:15 p.m., about two hours after the Edmund Fitzgerald. Captain Dudley J. Paquette of the Wilfred Sykes believed a major storm would cross directly over Lake Superior. He chose a route along the lake’s north shore to avoid the worst of the storm. The crew of the Wilfred Sykes heard the Edmund Fitzgerald and Arthur M. Anderson discuss taking the regular Lake Carriers’ Association route. At 7:00 p.m., the NWS changed its forecast, issuing gale warnings for all of Lake Superior. The Edmund Fitzgerald and Arthur M. Anderson turned north to seek shelter along the Ontario shore. They encountered a winter storm at 1:00 a.m. on November 10. The Edmund Fitzgerald reported winds of 52 knots (96 km/h; 60 mph) and waves 10 feet (3.0 m) high. Captain Paquette later heard McSorley say the ship had slowed due to rough conditions and that they were heading toward Isle Royale for protection.

At 2:00 a.m. on November 10, the NWS upgraded warnings to a storm, predicting winds of 35–50 knots (65–93 km/h; 40–58 mph). The Edmund Fitzgerald had been following the Arthur M. Anderson, which traveled at a steady 14.6 miles per hour (12.7 kn; 23.5 km/h). The faster Edmund Fitzgerald pulled ahead by about 3:00 a.m. As the storm passed, wind directions changed, temporarily reducing wind speeds. After 1:50 p.m., the Arthur M. Anderson recorded winds of 50 knots (93 km/h; 58 mph), and snow began falling at 2:45 p.m., reducing visibility. The Arthur M. Anderson lost sight of the Edmund Fitzgerald, which was 16 miles (26 km) ahead.

Shortly after 3:30 p.m., McSorley radioed the Arthur M. Anderson to report the Edmund Fitzgerald was taking on water, had lost two vent covers and a fence railing, and was tilting to one side. Two of the ship’s six bilge pumps ran continuously to remove water. McSorley said he would slow the ship to let the Arthur M. Anderson close the gap. The United States Coast Guard (USCG) warned all ships that the Soo Locks were closed and to find safe anchorage. Around 4:10 p.m., McSorley called the Arthur M. Anderson again to report a radar failure and asked for help tracking their position. The Edmund Fitzgerald slowed to let the Arthur M. Anderson get within 10 miles (16 km) to receive radar guidance.

For a time, the Arthur M. Anderson guided the Edmund Fitzgerald toward Whitefish Bay. At 4:39 p.m., McSorley contacted the USCG in Grand Marais, Michigan, to check if the Whitefish Point light and navigation beacon were working. The USCG said both were inactive. McSorley then asked ships in the Whitefish Point area about the navigational aids. Captain Cedric Woodard of the Avafors responded that the light was on but the radio beacon was not. Woodard later said he heard McSorley say, “Don’t allow nobody on deck,” and mention something about a vent he could not understand. Later, McSorley told Woodard, “I have a ‘bad list,’ I have lost both radars, and am taking heavy seas over the deck in one of the worst seas I have ever been in.”

By late afternoon on November 10, sustained winds over 50 knots (93 km/h; 58 mph) were recorded across eastern Lake Superior. The Arthur M. Anderson logged winds as high as 58 knots (107 km/h; 67 mph) at 4:52 p.m., with waves reaching 25 feet (7.6 m) by 6:00 p.m. The ship also faced gusts of 70–75 knots (130–139 km/h; 81–86 mph) and rogue waves up to 35 feet (11 m).

At about 7:10 p.m., the Arthur M. Anderson asked the Edmund Fitzgerald how it was doing. McSorley replied, “We are holding our own.” The Edmund Fitzgerald was never heard from again. No distress signal was received, and ten minutes later, the Arthur M. Anderson lost contact with the Edmund Fitzgerald by radio or radar.

Captain Cooper of the Arthur M. Anderson called the USCG in Sault Ste. Marie at 7:39 p.m. on channel 16, the distress frequency. The USCG asked him to call back on channel 12 to keep the emergency channel open. Cooper then contacted the Nanfri, a saltwater vessel, which said it could not detect the Edmund Fitzgerald on radar. After repeated attempts, Cooper reached

Wreck discovery and surveys

A U.S. Navy Lockheed P-3 Orion aircraft, piloted by Lt. George Conner, discovered the wreck using a magnetic anomaly detector on November 14, 1975, in Canadian waters near the international boundary at a depth of 530 feet (160 m). The Edmund Fitzgerald lies about 15 miles (13 nmi; 24 km) west of Deadman's Cove, Ontario; about 8 miles (7.0 nmi; 13 km) northwest of Pancake Bay Provincial Park; and 17 miles (15 nmi; 27 km) from the entrance to Whitefish Bay to the southeast. A survey by the U.S. Coast Guard from November 14–16 using side scan sonar found two large objects close together on the lake floor. The U.S. Navy also hired Seaward, Inc., to conduct a second survey between November 22 and 25.

From May 20 to 28, 1976, the U.S. Navy used its unmanned submersible, CURV-III, to dive on the wreck and found the Edmund Fitzgerald lying in two large pieces in 530 feet (160 m) of water. Navy estimates showed the bow section was 276 feet (84 m) long and the stern section was 253 feet (77 m) long. The bow section stood upright in the mud, about 170 feet (52 m) from the stern section, which lay upside down at a 50-degree angle from the bow. Between the two broken sections was a large pile of taconite pellets and scattered wreckage, including hatch covers and hull plating.

In 1980, during a Lake Superior research dive, marine explorer Jean-Michel Cousteau, the son of Jacques Cousteau, sent two divers from the RV Calypso in the first manned submersible dive to the Edmund Fitzgerald. The dive was short, and the team did not reach a final conclusion, but they thought the ship might have broken apart on the surface.

The Michigan Sea Grant Program organized a three-day dive in 1989 to survey the Edmund Fitzgerald. The goal was to record 3-D videotape for museum programs and documentaries. The expedition used a towed survey system (TSS Mk1) and a remotely operated underwater vehicle (ROV) called the Mini Rover. The Mini Rover had cameras and lenses to create 3-D images. The equipment was designed and operated by Chris Nicholson of Deep Sea Systems International, Inc. Participants included NOAA, the National Geographic Society, the U.S. Army Corps of Engineers, the Great Lakes Shipwreck Historical Society (GLSHS), and the U.S. Fish and Wildlife Service, which provided the support vessel RV Grayling. The GLSHS used part of the video in a documentary, and the National Geographic Society used a segment in a broadcast. Frederick Stonehouse, who wrote one of the first books about the Edmund Fitzgerald wreck, reviewed the video in 1990 but did not find a cause for the ship’s sinking.

In 1994, Canadian explorer Joseph B. MacInnis led six publicly funded dives to the Edmund Fitzgerald over three days. The Harbor Branch Oceanographic Institution provided the support vessel Edwin A. Link and the submersible Celia. The GLSHS paid $10,000 for three members to join a dive and take still pictures. MacInnis concluded that the notes and video from the dives did not explain why the ship sank. That same year, Fred Shannon formed Deepquest Ltd. and organized a privately funded dive using the submersible Delta. Deepquest conducted seven dives and recorded over 42 hours of underwater video. Shannon set a record for the longest submersible dive to the Edmund Fitzgerald at 211 minutes. Before the dives, Shannon studied NOAA charts and found that the international boundary had changed three times before 1976. Using GPS data from the 1994 expedition, Shannon determined that at least one-third of the wreckage area is in U.S. waters due to an error in the boundary line on official charts.

Shannon’s group found the remains of a crew member wearing a life jacket and coveralls near the ship’s bow, suggesting the crew knew the ship might sink. The life jacket had deteriorated fabric and six rectangular cork blocks. Shannon concluded that the ship broke apart on the surface due to "massive and advancing structural failure."

In 1995, MacInnis led another series of dives to recover the ship’s bell. The Sault Tribe of Chippewa Indians supported the expedition with a $250,000 loan. Canadian engineer Phil Nuytten used his atmospheric diving suit, the Newtsuit, to retrieve the bell, replace it with a replica, and place a beer can in the ship’s pilothouse. That same year, Terrence Tysall and Mike Zee set records by diving to the Edmund Fitzgerald using trimix gas. They are the only people known to have touched the wreck. They also set records for the deepest scuba dive on the Great Lakes and the deepest shipwreck dive, and were the first to reach the wreck without a submersible. It took six minutes to reach the wreck, six minutes to survey it, and three hours to resurface to avoid decompression sickness.

Under the Ontario Heritage Act, activities on registered archaeological sites require a license. In March 2005, the Whitefish Point Preservation Society accused the GLSHS of conducting an unauthorized dive to the Edmund Fitzgerald. The GLSHS director admitted to a sonar scan in 2002 but said a license was not required at the time.

An April 2005 amendment to the Ontario Heritage Act allowed the government to require licenses for dives, submersible operations, sonar scans, or underwater cameras near protected sites. Fines of up to CA$1 million could be imposed for unauthorized activities. In January 2006, the Ontario government updated regulations to protect wreck sites, creating a 500-meter (1,640 ft) radius around the Edmund Fitzgerald and other sites. In 2009, the Ontario Heritage Act was amended again to require licenses for all surveying devices.

Hypotheses on the cause of sinking

Extreme weather and sea conditions are part of all the published theories about the Edmund Fitzgerald's sinking, but the theories differ about other causes.

In 2005, NOAA and the NWS ran a computer simulation that included weather and wave conditions from November 9, 1975, until early morning on November 11. The simulation showed that two areas of high-speed wind appeared over Lake Superior at 4:00 p.m. on November 10. One area had wind speeds over 43 knots (80 km/h; 49 mph), and the other had winds over 40 knots (74 km/h; 46 mph). The southeastern part of the lake, where the Edmund Fitzgerald was heading, had the strongest winds. By 7:00 p.m. on November 10, average wave heights reached nearly 19 feet (5.8 m), and winds exceeded 50 mph (43 kn; 80 km/h) across most of the southeastern part of Lake Superior.

The Edmund Fitzgerald sank at the edge of the high-wind area where long fetch, or the distance wind blows over water, created large waves. By 7:00 p.m., waves averaged over 23 feet (7.0 m), and by 8:00 p.m., they reached over 25 feet (7.6 m). The simulation showed that one in 100 waves reached 36 feet (11 m), and one in 1,000 reached 46 feet (14 m). Since the ship was heading east-southeast, it is likely that the waves caused the Edmund Fitzgerald to roll heavily.

At the time of the sinking, the ship Arthur M. Anderson reported northwest winds of 57 mph (50 kn; 92 km/h), which matched the simulation’s result of 54 mph (47 kn; 87 km/h). The analysis also showed that maximum sustained winds near the Edmund Fitzgerald’s sinking location reached about 70 mph (61 kn; 110 km/h), with gusts up to 86 mph (75 kn; 138 km/h).

A group of three large waves, called "three sisters," was reported near the Edmund Fitzgerald when it sank. This phenomenon, which occurs on Lake Superior, involves three waves that are one-third larger than normal. The first wave brings a large amount of water onto the ship’s deck. This water does not fully drain before the second wave hits, adding more water. The third wave adds even more water, quickly overwhelming the deck.

Captain Cooper of the Arthur M. Anderson reported that his ship was hit by two waves, each 30 to 35 feet (9 to 11 m) high, about 6:30 p.m. One wave buried the ship’s aft cabins and damaged a lifeboat by pushing it onto the saddle. A second wave of similar size struck the bridge deck. Cooper said these waves, possibly followed by a third, likely hit the Edmund Fitzgerald around the time it sank. This theory suggests that the "three sisters" worsened the ship’s known list (tilt) and its slower speed in heavy seas, which allowed water to stay on the deck longer.

The 2010 television series Dive Detectives included a simulation of a 17-meter (56 ft) rogue wave’s effect on a model of the Edmund Fitzgerald. The simulation showed that such a wave could temporarily submerge the ship’s bow or stern.

The USCG Marine Casualty Report from July 26, 1977, suggested that the accident was caused by ineffective hatch closures. The report stated that these closures failed to stop waves from flooding the cargo hold. The flooding happened gradually and likely went unnoticed until the ship lost buoyancy and stability, causing it to sink suddenly. Video footage of the wreck showed that most hatch clamps were in good condition. The USCG concluded that the few damaged clamps were probably the only ones fastened, leading to the ship’s flooding and sinking.

From the start of the USCG investigation, some crew members’ families and labor groups believed the findings might be biased due to concerns about the crew’s preparedness and changes to licensing rules. Paul Trimble, a retired USCG vice admiral and president of the Lake Carriers Association (LCA), wrote to the NTSB in 1977, stating that current hatch covers were advanced and had proven reliable for nearly 40 years without any vessel losses. He also noted that clamps were not always locked during sailing and were set later based on weather conditions.

The NTSB’s findings from May 4, 1978, differed from the USCG. Based on the CURV-III survey, the NTSB observed that hatch covers were damaged or missing, and many clamps were broken or open. The NTSB concluded that the Edmund Fitzgerald sank suddenly due to flooding from the collapse of hatch covers under the force of large waves, not from gradual leakage. A dissenting opinion suggested the ship sank due to shoaling (grounding on an underwater reef).

The LCA believed that shoaling, not hatch cover failure, was the likely cause of the Edmund Fitzgerald’s sinking. They pointed to a 1976 Canadian survey that revealed an unknown shoal near Six Fathom Shoal, which the Edmund Fitzgerald may have unknowingly hit. Officers from the Arthur M. Anderson reported that the Edmund Fitzgerald sailed through this area. Supporters of the shoaling theory suggested that the ship’s broken fence rail, reported by McSorley, could only have happened if the ship struck a reef.

Possible contributing factors

The U.S. Coast Guard (USCG), the National Transportation Safety Board (NTSB), and supporters of other theories have identified several possible reasons for the sinking of the Edmund Fitzgerald.

On November 9, the National Weather Service (NWS) predicted a storm would move south of Lake Superior and over the Keweenaw Peninsula, extending into the lake from Michigan’s Upper Peninsula. Captain Paquette of the Wilfred Sykes had been tracking a low-pressure system over Oklahoma since November 8 and believed a major storm would cross eastern Lake Superior. He chose a route that offered the Wilfred Sykes the most protection and took shelter in Thunder Bay, Ontario, during the storm’s worst conditions. In contrast, Arthur M. Anderson and the Edmund Fitzgerald followed the regular Lake Carriers Association route, placing them directly in the storm’s path. The NTSB investigation found the NWS did not accurately predict wave heights on November 10. In 2005, NWS researcher Hultquist said the Edmund Fitzgerald’s position in the storm was “precisely the wrong place at the absolute worst time.”

After learning the Edmund Fitzgerald had passed near shoals north of Caribou Island, the USCG Marine Board reviewed navigational charts. They found the 1973 Canadian chart for the Six Fathom Shoal area was based on surveys from 1916 and 1919. The 1973 U.S. Lake Survey Chart No. 9 included a note stating, “Canadian Areas. For data concerning Canadian areas, Canadian authorities have been consulted.” In 1976, the Canadian Hydrographic Service surveyed the area around Michipicoten and Caribou Islands and discovered the shoal extended about 1 mile farther east than shown on Canadian charts. The NTSB concluded that Lake Survey Chart No. 9 was not detailed enough to show Six Fathom Shoal as a navigation hazard at the time of the Edmund Fitzgerald’s sinking.

Thompson said if the Edmund Fitzgerald had watertight subdivisions in its cargo holds, “the Edmund Fitzgerald could have made it into Whitefish Bay.” Frederick Stonehouse also believed the lack of watertight bulkheads caused the ship to sink. He stated:

“The Great Lakes ore carrier is the most commercially efficient vessel in the shipping trade today. But it’s nothing but a motorized barge! It’s the unsafest commercial vessel afloat. It has virtually no watertight integrity. Theoretically, a one-inch puncture in the cargo hold will sink it.”

Stonehouse compared the Edmund Fitzgerald to the SS Maumee, an oceangoing tanker that struck an iceberg near the South Pole. The collision created a large hole in the ship’s bow, but the Maumee reached a repair yard because it had watertight bulkheads.

After the Edmund Fitzgerald sank, Great Lakes shipping companies were criticized for prioritizing cargo capacity over safety. The ship’s cargo hold of 860,950 cubic feet (24,379 m³) was divided by two non-watertight “screen” bulkheads. The NTSB investigation concluded that Great Lakes freighters should be built with watertight bulkheads in their cargo holds.

The USCG had proposed rules for watertight bulkheads as early as 1966, after the sinking of the Daniel J. Morrell, and again after the Edmund Fitzgerald’s sinking. They argued that such rules would help ships reach safety or allow crews to abandon ship safely. The Lake Carriers Association (LCA), which represented Great Lakes fleet owners, opposed these rules, claiming they would cause economic hardship. Some vessels built after 1975 included watertight subdivisions, but most Great Lakes ships still could not prevent flooding of the entire cargo hold area.

A fathometer, a device used to measure water depth, was not required under USCG regulations at the time. The Edmund Fitzgerald did not have one, even though fathometers were available. Instead, the ship used a hand line—a rope with knots at measured intervals and a lead weight—to take depth soundings. The NTSB concluded a fathometer would have provided the Edmund Fitzgerald with additional navigational data and reduced reliance on Arthur M. Anderson for navigation.

The Edmund Fitzgerald had no system to monitor water in its cargo hold, even though some water was always present. The November 10 storm made it difficult or impossible to access the hatches from the spar deck (the deck above the cargo holds). The USCG Marine Board found that flooding could not be assessed until water reached the top of the taconite cargo. The NTSB concluded it would have been impossible to pump water from the hold when it was filled with bulk cargo. The Marine Board noted the ship lacked a draft-reading system, so the crew could not determine if the vessel had lost freeboard (the level of a ship’s deck above the water).

The USCG increased the Edmund Fitzgerald’s load line in 1969, 1971, and 1973, allowing 3 feet 3.25 inches (997 mm) less minimum freeboard than the ship’s original design. This meant the ship’s deck was only 11.5 feet (3.5 m) above the water when it faced 35-foot (11 m) waves during the November 10 storm. Captain Paquette of the Wilfred Sykes noted this change allowed the Edmund Fitzgerald to carry 4,000 more tons than designed.

Concerns about the Edmund Fitzgerald’s keel-welding problem arose as the USCG increased its load line. This change reduced the ship’s critical reserve buoyancy, making it slower to respond to heavy seas. The ship’s bow tilted to one side or the other in rough waves without recovering and made a groaning sound not heard on other ships. Captain McSorley described the ship’s movement as a “wiggling thing” that frightened him.

NTSB investigators noted that the Edmund Fitzgerald’s earlier groundings could have caused undetected damage leading to structural failure during the storm. Great Lakes vessels were typically drydocked for inspection only once every five years. It was also claimed that Captain McSorley did not maintain the ship as thoroughly as the previous captain, Peter Pulcer. After examining photographs of the Edmund Fitzgerald’s welds, August B. Herbel Jr., president of the American Society for Testing and Materials, stated, “the hull was just being held together with patching plates.” Questions also arose about why the USCG did not address poor maintenance of the ship’s hatch coamings, gaskets, and clamps during its pre-November 1975 inspection.

On the evening of November 10, 1975, Captain McSorley reported he had never seen bigger waves in his life. Captain Paquette of the Wilfred Sykes, also in the storm, said, “I’ll tell anyone that it was a monster sea washing solid water over the deck of every vessel.”

Legal settlement

Under maritime law, ships are controlled by the admiralty courts of the country whose flag they fly. The ship Edmund Fitzgerald was sailing under the U.S. flag, so even though it sank in Canadian waters, it was subject to U.S. admiralty law. The ship’s financial loss of $24 million was the largest in Great Lakes sailing history. In addition to the crew, 26,116 long tons (29,250 short tons; 26,535 t) of taconite also sank with the vessel. Two widows of crew members sued the ship’s owners, Northwestern Mutual, and its operators, Oglebay Norton Corporation, for $1.5 million one week after the ship sank. A second lawsuit for $2.1 million was later filed. Oglebay Norton then asked the U.S. District Court to reduce its liability to $817,920 in connection with other lawsuits by families of crew members. The company paid money to surviving families about 12 months before official findings about the probable cause of the sinking, but only after families agreed to keep the information private. Robert Hemming, a reporter and newspaper editor, wrote in his book about Edmund Fitzgerald that the U.S. Coast Guard’s conclusions did not blame the company or the captain and helped Oglebay Norton avoid costly lawsuits by the families of the lost crew.

Subsequent changes to Great Lakes shipping practice

The U.S. Coast Guard (USCG) investigation into the sinking of the Edmund Fitzgerald led to 15 recommendations about rules for ship weight limits, how well ships can stay dry during storms, search and rescue abilities, life-saving equipment, crew training, loading manuals, and giving information to ship captains on Great Lakes vessels. The National Transportation Safety Board (NTSB) investigation resulted in 19 recommendations for the USCG, four for the American Bureau of Shipping, and two for the National Oceanic and Atmospheric Administration (NOAA). Based on these official recommendations, the following actions and USCG rules were created:

Karl Bohnak, a meteorologist from the Upper Peninsula, wrote a book about local weather history that included the Fitzgerald’s sinking and the storm. In the book, Joe Warren, a deckhand on the Arthur M. Anderson during the November 10, 1975, storm, said the storm changed how things were done. He stated, "After that, trust me, when a gale came up we dropped the hook [anchor]. We dropped the hook because they found out the big ones could sink." Mark Thompson wrote, "Since the loss of the Fitz, some captains may be more prone to go to anchor, rather than venturing out in a severe storm, but there are still too many who like to portray themselves as 'heavy weather sailors.'"

Memorials

The day after the wreck, Mariners' Church in Detroit rang its bell 29 times, once for each life lost. The church held an annual memorial, reading the names of the crewmen and ringing the bell, until 2006, when the ceremony expanded to honor all lives lost on the Great Lakes. After singer Gordon Lightfoot died on May 1, 2023, the church rang its bell 29 times for the crew, plus one additional ring in memory of Lightfoot, who helped keep the story of the wreck known.

The ship's bell was recovered from the wreck on July 4, 1995. A replica engraved with the names of the 29 sailors who died replaced the original on the wreck. A legal document signed by 46 relatives of the deceased, officials from Mariners' Church of Detroit, and the Great Lakes Shipwreck Historic Society (GLSHS) gave the GLSHS the responsibility to care for and protect the bell, ensuring it would be used in a permanent memorial at Whitefish Point, Michigan, to honor the 29 men of the SS Edmund Fitzgerald. The agreement required the GLSHS to maintain the bell, prohibit its sale or movement, and transfer it to Mariners' Church if the rules were broken.

In 1995, a controversy arose when a worker in St. Ignace, Michigan, removed the protective coating on the bell, which had been applied by experts from Michigan State University. The issue continued in 1996 when the Great Lakes Shipwreck Museum tried to display the bell as part of a traveling exhibit. Relatives of the crew opposed this, calling it a "traveling trophy." As of 2005, the bell is on display at the Great Lakes Shipwreck Museum in Whitefish Point, near Paradise, Michigan.

An anchor from the Edmund Fitzgerald, lost during a trip in 1974, was recovered from the Detroit River on July 20, 1992, and is now displayed at the Dossin Great Lakes Museum in Detroit, Michigan. The Dossin Museum also hosts an annual event called the Lost Mariners Remembrance on November 10. The Steamship Valley Camp museum in Sault Ste. Marie displays two lifeboats, photos, a film about the Edmund Fitzgerald, and commemorative models and paintings. Every November 10, the Split Rock Lighthouse near Silver Bay, Minnesota, sends out a light to honor the Edmund Fitzgerald.

On August 8, 2007, a family in Michigan found a life-saving ring on Lake Superior’s Keweenaw Peninsula. The ring had markings different from those found at the wreck site, leading some to believe it was a fake. Later, it was confirmed that the ring was not from the Edmund Fitzgerald but had been lost by its owner, whose father had created it as a personal memorial.

In 2015, the Royal Canadian Mint released a colored silver coin worth $20 to honor the Edmund Fitzgerald.

From July 26 to August 28, 2025, the Edmund Fitzgerald Memorial Swim took place to mark the 50th anniversary of the sinking. Sixty-eight swimmers used a relay system to carry taconite pellets from the ship’s resting place near Superior, Wisconsin, to Detroit, a distance of 411 miles (661 km). The pellets were presented to Detroit’s deputy mayor at Mariners’ Church during memorial ceremonies.

Ontario singer-songwriter Gordon Lightfoot wrote the song "The Wreck of the Edmund Fitzgerald" for his 1976 album Summertime Dream. He was inspired to write the song after seeing the ship’s name misspelled as "Edmond" in a magazine. Lightfoot believed the error dishonored the 29 who died. His song became one of the most well-known accounts of the disaster. The original lyrics differ slightly from the actual events: the song mentions Cleveland as the ship’s destination instead of Detroit. Lightfoot later changed a line in live performances, replacing "At 7 p.m. a main hatchway caved in" with "At 7 p.m. it grew dark, it was then." He also changed the word "musty" to "rustic" in a reference to Mariners’ Church, as the building is not actually musty or a cathedral.

On May 2, 2023, Mariners’ Church of Detroit rang its bell 30 times—29 for the crew of the Edmund Fitzgerald and one for Gordon Lightfoot, who died on May 1, 2023.

In 1986, writer Steven Dietz and songwriter Eric Peltoniemi created the musical Ten November to honor the Edmund Fitzgerald’s sinking. In 2005, the play was revised as The Gales of November and performed at the Fitzgerald Theater in St. Paul, Minnesota, on the 30th anniversary of the wreck.

In 2000, Shelley Russell staged her play Holdin' Our Own: The Wreck of the Edmund Fitzgerald at the Forest Roberts Theatre on Northern Michigan University’s campus. The production featured 14 actors, with 11 on the Edmund Fitzgerald and three on the Arthur M. Anderson.

In 2002, American composer Geoffrey Peterson wrote a piano concerto titled The Edmund Fitzgerald. It was first performed by the Sault Symphony Orchestra in Sault Ste. Marie, Ontario, in 2005 as part of the 30th-anniversary commemorations.

The story of the Edmund Fitzgerald and its historical significance have become widely known, leading to the creation of memorabilia such as Christmas ornaments, T-shirts, coffee mugs, videos, and other items. These items are sold across the Great Lakes region, from Two Harbors, Minnesota, to Whitefish Point, where the wreck occurred.
