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 North America’s Great Lakes and remains the largest ship to have sunk there. On November 14, 1975, a U.S. Navy aircraft found the ship in deep water by detecting magnetic changes and later discovered it had broken into two large pieces.

For 17 years, the Edmund Fitzgerald transported 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 cargo records six times, often beating its own previous records. Captain Peter Pulcer was known for playing music over the ship’s intercom while traveling through the St. Clair and Detroit rivers and for giving live updates to people watching the ship pass through the Soo Locks. These actions made the Edmund Fitzgerald popular among people who watched ships on the lakes.

On the afternoon of November 9, 1975, the Edmund Fitzgerald began its final trip from Superior, Wisconsin, carrying taconite ore pellets with Captain Ernest M. McSorley in charge. While traveling to a steel mill near Detroit, the ship encountered a severe storm the next day with very strong winds and waves as high as 35 feet (11 meters). Around 5:30 p.m., the ship reported it was in trouble. At 7:10 p.m., Captain McSorley sent his last message: “We are holding our own.” Shortly after 7:10 p.m., the Edmund Fitzgerald 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 overwhelmed by water, suffering structural damage, hitting a shallow area, or a mix of these issues.

The sinking of the Edmund Fitzgerald is one of the most well-known events in Great Lakes shipping history. This is partly because Canadian singer Gordon Lightfoot wrote a popular song about it in 1976 titled “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, including requirements for survival suits, depth finders, positioning systems, higher freeboard on ships, and more frequent inspections of vessels.

History

Northwestern Mutual Life Insurance Company of Milwaukee, Wisconsin, invested heavily in the iron and minerals industries. This included building the Edmund Fitzgerald, the first ship of its kind funded by an American life insurance company. In 1957, the company hired Great Lakes Engineering Works (GLEW) from River Rouge, Michigan, to design and construct the ship. The ship was built to be almost as long as the maximum allowed size for the Saint Lawrence Seaway, which was being completed at the time. At that time, the ship was worth $7 million (about $59.6 million in 2024). The Edmund Fitzgerald was the first ship on the Great Lakes built to the maximum size allowed by the Saint Lawrence Seaway. It was 730 feet (222.5 meters) long, 75 feet (22.9 meters) wide, and had a 25-foot (7.6 meters) draft. The ship’s hull was 39 feet (12 meters) tall, and the cargo area inside was 33 feet 4 inches (10.16 meters) high. GLEW placed the first steel plate for the ship’s keel on August 7, 1957.

The Edmund Fitzgerald had a carrying capacity of 26,000 long tons (29,120 short tons; 26,417 metric tons) and a 729-foot (222 meters) hull. It was the longest ship on the Great Lakes until September 17, 1959, when the 730-foot (222.5 meters) SS Murray Bay was launched. The ship had three main cargo areas that were loaded through 21 watertight hatches. Each hatch was 11 by 48 feet (3.4 by 14.6 meters) and made of steel that was 5/16 inch (7.9 mm) thick. In 1969, the ship’s ability to move smoothly 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 period.

Compared to other ore freighters, the inside of the Edmund Fitzgerald was considered very comfortable. Its furnishings, designed by the J. L. Hudson Company, included thick carpets, tiled bathrooms, curtains over the portholes, and leather swivel chairs in the guest lounge. There were two rooms for passengers. Air conditioning was used in the crew quarters, which had more comforts than usual. A large kitchen and well-stocked pantry provided meals for two dining areas. The ship’s pilothouse had advanced navigation equipment and a beautiful map room.

Northwestern Mutual wanted to name the ship after its president and chairman, Edmund Fitzgerald. Fitzgerald’s grandfather and uncles had all been lake captains, and his father owned the Milwaukee Drydock Company, which built and repaired ships. Fitzgerald tried to stop the ship from being named after him, suggesting names like Centennial, Seaway, Milwaukee, and Northwestern. The board of directors decided to name the ship after him, and all 36 members voted unanimously for the name SS Edmund Fitzgerald. Over 15,000 people attended the ship’s christening and launch on June 7, 1958. The event had problems. Elizabeth Fitzgerald, Edmund’s wife, tried to break a champagne bottle over the ship’s bow but needed three attempts. Another guest, Jennings B. Frazier, had a heart attack and died. A 36-minute delay occurred while the ship’s keel blocks were released. When the ship was launched, it created a large wave that soaked the crowd, then crashed into a pier before righting itself. Some witnesses later said the ship seemed to be “trying to climb out of the water.” On September 22, 1958, the Edmund Fitzgerald completed nine days of sea trials.

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

The Edmund Fitzgerald was a record-breaking ship. Its highest single-trip load was 27,402 long tons (30,690 short tons; 27,842 metric tons) in 1969. For 17 years, the ship transported taconite from Minnesota’s Iron Range near Duluth to iron works in Detroit, Toledo, and other ports. It set seasonal haul records six times. The ship was nicknamed “Fitz,” “Pride of the American Flag,” “Mighty

Final voyage and wreck

Ernest M. McSorley (September 29, 1912 – November 10, 1975) was the last captain of the SS Edmund Fitzgerald. He died along with the other 28 members of his crew on November 10, 1975. The SS Edmund Fitzgerald left Superior, Wisconsin, at 2:15 p.m. on November 9, 1975, under the command of Master Captain McSorley. The ship was heading to the 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 full speed of 16.3 miles per hour (14.2 kn; 26.2 km/h). Around 5 p.m., the SS Edmund Fitzgerald joined a second freighter, the SS Arthur M. Anderson, which was heading to Gary, Indiana, from Two Harbors, Minnesota. The weather forecast was typical for November, and the National Weather Service (NWS) predicted that a storm would pass just south of Lake Superior by 7 a.m. on November 10.

The SS Wilfred Sykes loaded at the Burlington Northern Dock #1 and left at 4:15 p.m., about two hours after the SS Edmund Fitzgerald. Captain Dudley J. Paquette of the SS Wilfred Sykes predicted that a major storm would directly cross Lake Superior. He chose a route that used the protection of the lake’s north shore to avoid the worst effects of the storm. The crew of the SS Wilfred Sykes listened to the radio conversations between the SS Edmund Fitzgerald and the SS Arthur M. Anderson and heard their captains decide to take the regular Lake Carriers’ Association downbound route. At 7:00 p.m., the NWS changed its forecast, issuing gale warnings for all of Lake Superior. The SS Edmund Fitzgerald and the SS Arthur M. Anderson changed course northward, seeking shelter along the Ontario shore, where they encountered a winter storm at 1:00 a.m. on November 10. The SS Edmund Fitzgerald reported winds of 52 knots (96 km/h; 60 mph) and waves 10 feet (3.0 m) high. Captain Paquette of the SS Wilfred Sykes reported that after 1 a.m., he overheard McSorley say that he had reduced the ship’s speed because of the rough conditions. Paquette said he was surprised to later hear McSorley, who was not known for turning aside or slowing down, say, “We’re going to try for some lee from Isle Royale. You’re walking away from us anyway … I can’t stay with you.”

At 2:00 a.m. on November 10, the NWS upgraded its warnings from gale to storm, predicting winds of 35–50 knots (65–93 km/h; 40–58 mph). Until then, the SS Edmund Fitzgerald had followed the SS Arthur M. Anderson, which was traveling at a constant 14.6 miles per hour (12.7 kn; 23.5 km/h), but the faster SS Edmund Fitzgerald pulled ahead at about 3:00 a.m. As the storm center passed over the ships, they experienced shifting winds, with wind speeds temporarily dropping as the wind direction changed from northeast to south and then northwest. After 1:50 p.m., when the SS Arthur M. Anderson logged winds of 50 knots (93 km/h; 58 mph), wind speeds again picked up rapidly, and it began to snow at 2:45 p.m., reducing visibility. The SS Arthur M. Anderson lost sight of the SS Edmund Fitzgerald, which was about 16 miles (26 km) ahead at the time.

Shortly after 3:30 p.m., Captain McSorley radioed the SS Arthur M. Anderson to report that the SS Edmund Fitzgerald was taking on water and had lost two vent covers and a fence railing. The vessel had also developed a list. Two of the SS Edmund Fitzgerald’s six bilge pumps ran continuously to discharge the water. McSorley said he would slow his ship down so that the SS Arthur M. Anderson could close the gap between them. In a broadcast shortly afterward, the United States Coast Guard (USCG) warned all shipping that the Soo Locks had been closed and they should seek safe anchorage. Shortly after 4:10 p.m., McSorley called the SS Arthur M. Anderson again to report a radar failure and asked the SS Arthur M. Anderson to keep track of them. The SS Edmund Fitzgerald, effectively blind, slowed to let the SS Arthur M. Anderson come within a 10-mile (16 km) range so it could receive radar guidance from the other ship.

For a time, the SS Arthur M. Anderson directed the SS Edmund Fitzgerald toward the relative safety of Whitefish Bay. Then, at 4:39 p.m., McSorley contacted the USCG station in Grand Marais, Michigan, to inquire whether the Whitefish Point light and navigation beacon were operational. The USCG replied that their monitoring equipment indicated that both instruments were inactive. McSorley then hailed any ships in the Whitefish Point area to report the state of the navigational aids, receiving an answer from Captain Cedric Woodard of the SS Avafors between 5:00 and 5:30 p.m. that the Whitefish Point light was on but not the radio beacon. Woodard testified to the Marine Board that he overheard McSorley say, “Don’t allow nobody on deck,” as well as something about a vent that Woodard could not understand. Some time 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 in the afternoon of November 10, sustained winds of over 50 knots (93 km/h; 58 mph) were recorded by ships and observation points across eastern Lake Superior. The SS Arthur M. Anderson logged sustained winds as high as 58 knots (107 km/h; 67 mph) at 4:52 p.m., while waves increased to as high as 25 feet (7.6 m) by 6:00 p.m. The SS Arthur M. Anderson was also struck by 70-to-75-knot (130 to 139 km/h; 81 to 86 mph) gusts and rogue waves as high as 35 feet (11 m).

At approximately 7:10 p.m., when the SS Arthur M. Anderson notified the SS Edmund Fitzgerald of an upbound ship and asked how she was doing, McSorley reported, “We are holding our own.” She was never heard from again. No distress signal was received, and ten minutes later, the SS Arthur M. Anderson lost the ability either to reach the SS Edmund Fitzgerald by radio or to detect her on radar.

Wreck discovery and surveys

On November 14, 1975, a U.S. Navy Lockheed P-3 Orion aircraft, flown by Lt. George Conner, discovered the wreck of the Edmund Fitzgerald using a magnetic anomaly detector in Canadian waters near the international boundary at a depth of 530 feet (160 m). The wreck 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 from November 14 to 16 by the U.S. Coast Guard 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 at a depth of 530 feet (160 m). Navy estimates showed the bow section was 276 feet (84 m) long and the stern section was 253 feet (77 m) long. The bow stood upright in the mud, about 170 feet (52 m) from the stern, which lay capsized at a 50-degree angle. Between the two 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, son of Jacques Cousteau, sent two divers from the RV Calypso in a manned submersible 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.

In 1989, the Michigan Sea Grant Program organized a three-day dive to study the Edmund Fitzgerald. The goal was to record 3-D video for museums and documentaries. The expedition used a towed survey system (TSS Mk1) and a remotely operated underwater vehicle (ROV) called the Mini Rover. The ROV had cameras to create 3-D images. Chris Nicholson of Deep Sea Systems International, Inc., designed, built, and operated the equipment. 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 some video footage in a documentary, and the National Geographic Society used a segment in a broadcast. Frederick Stonehouse, who wrote one of the first books on the Edmund Fitzgerald wreck, reviewed the video in 1990 but did not reach a conclusion about the cause of the 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 manned submersible Celia. The GLSHS paid $10,000 for three members to join a dive and take still pictures. MacInnis said the notes and video from the dives did not explain why the Edmund Fitzgerald 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 video. Shannon set a record for the longest submersible dive to the wreck at 211 minutes. Before the dives, Shannon studied NOAA charts and found that the international boundary had changed three times before 1976. Using GPS coordinates from the 1994 expedition, Shannon concluded that at least one-third of the wreck site 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 bow, suggesting the crew knew the ship might sink. The life jacket had deteriorated canvas and six rectangular cork blocks. Shannon believed "massive and advancing structural failure" caused the ship to break apart on the surface and sink.

In 1995, MacInnis led another series of dives to recover the bell from the Edmund Fitzgerald. The Sault Tribe of Chippewa Indians helped fund the expedition with a $250,000 loan. Canadian engineer Phil Nuytten's Newtsuit atmospheric diving suit was used to retrieve the bell, replace it with a replica, and put a beer can in the ship's pilothouse. That same year, Terrence Tysall and Mike Zee set records by using trimix gas to scuba dive to the wreck. They are the only people known to have touched the Edmund Fitzgerald wreck. They also set records for the deepest scuba dive on the Great Lakes and the deepest shipwreck dive. They reached the wreck in six minutes, spent six minutes surveying it, and took 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 no license was needed at the time.

An April 2005 amendment to the Ontario Heritage Act allowed the government to require licenses for dives, submersibles, sonars, 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

Hypotheses on the cause of sinking

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

In 2005, NOAA and the NWS used a computer to simulate weather and wave conditions from November 9 to November 11, 1975. The simulation showed two areas of very strong wind 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 wind speeds over 40 knots (74 km/h; 46 mph). The southeastern part of the lake, where the Edmund Fitzgerald was traveling, had the strongest winds. By 7:00 p.m. on November 10, average wave heights reached nearly 19 feet (5.8 m), and winds over most of the southeastern lake exceeded 50 mph (43 kn; 80 km/h).

The Edmund Fitzgerald sank near the edge of the high-wind area where the 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 averaged over 25 feet (7.6 m). The simulation also 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, the waves likely caused it 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), close to the simulation’s result of 54 mph (47 kn; 87 km/h). The analysis also found 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 occurs on Lake Superior and involves three waves that are one-third larger than normal. The first wave adds water to the ship’s deck, which does not fully drain before the second wave hits. The third wave adds more water, causing the deck to flood quickly.

Captain Cooper of the Arthur M. Anderson said his ship was hit by two waves between 30 and 35 feet high around 6:30 p.m. One wave damaged the ship’s aft cabins and a lifeboat, and the second wave hit the bridge deck. These waves likely reached the Edmund Fitzgerald shortly before it sank. This theory suggests that the “three sisters” worsened the ship’s known list (tilting) and its slower speed in rough seas, which allowed water to stay on the deck longer.

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

The USCG’s 1977 report said the accident happened because the ship’s hatches were not closed properly. The report concluded that the hatches failed to stop waves from flooding the cargo hold. The flooding happened slowly and was not noticed until the ship lost buoyancy and stability, causing it to sink suddenly. Video of the wreck showed most hatch clamps were in good condition, and the USCG said only a few damaged clamps were likely used. This led to the conclusion that poor hatch closure caused the ship to flood and sink.

Some crew families and labor groups questioned the USCG’s findings, believing the investigation might have been biased. Paul Trimble, a retired USCG vice admiral, wrote to the NTSB in 1977, saying that it was common for ore freighters to leave some hatch clamps unlocked in bad weather. Captain Paquette of the Wilfred Sykes said he often used the minimum number of clamps in good weather.

The NTSB’s 1978 findings disagreed with the USCG. The NTSB studied the forces needed to collapse the hatches and concluded the ship sank suddenly due to flooding from waves breaking the hatches, not from gradual flooding. The NTSB also noted that the ship might have sunk suddenly due to shoaling (running aground on a shallow area).

The Lake Carriers Association (LCA) suggested that the ship might have run aground on a shoal near Caribou Island, where a hidden reef was discovered in a 1976 survey. Officers from the Arthur M. Anderson said the Edmund Fitzgerald passed through that area. Supporters of this theory said the ship’s broken fence rail could only happen if the ship “hogged” (bent upward in the middle) during grounding. However, divers found no signs of a collision or grounding on the shoal. Later photography of the wreck showed no evidence the ship hit a shoal.

Maritime author Stonehouse noted that the USCG had no financial interest in the investigation, unlike the LCA. Captain Paquette said the LCA supported the shoaling theory to avoid blame for its member companies.

Paul Hainault, a retired professor from Michigan Technological University, proposed a theory based on a student project. His hypothesis suggested that…

Possible contributing factors

The USCG, NTSB, and supporters of other theories have listed several possible reasons for the sinking of the Edmund Fitzgerald.

On November 9, the NWS predicted a storm would move south of Lake Superior and over the Keweenaw Peninsula, reaching 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 worst of the storm. Based on the NWS forecast, 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, Hultquist of the NWS used actual weather data from November 10, 1975, and said, “The Edmund Fitzgerald ended in precisely the wrong place at the absolute worst time.”

After learning that the Edmund Fitzgerald had passed near shoals north of Caribou Island, the USCG Marine Board reviewed navigational charts. They discovered the Canadian 1973 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.” At the request of the Marine Board and the USCG Ninth District Commander, the Canadian Hydrographic Service surveyed the area around Michipicoten Island and Caribou Island in 1976. The survey found the shoal extended about 1 mile (1.6 km) 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 stated that if the Edmund Fitzgerald had had watertight subdivisions in its cargo holds, “the Edmund Fitzgerald could have made it into Whitefish Bay.” Frederick Stonehouse also said the lack of watertight bulkheads caused the Edmund Fitzgerald to sink. He said:

Stonehouse compared the design of lake carriers to ships rather than “motorized super-barges.”

After the Edmund Fitzgerald sank, Great Lakes shipping companies were criticized for prioritizing cargo 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 Great Lakes freighters should be built with watertight bulkheads in their cargo holds.

The USCG proposed rules for watertight bulkheads in Great Lakes vessels as early as the sinking of the Daniel J. Morrell in 1966 and again after the Edmund Fitzgerald sank. They argued this would allow ships to reach safety or let crews abandon ship in an orderly way. The Lake Carriers Association, which represented Great Lakes fleet owners, opposed the rules, claiming they would cause economic hardship. Some vessels built after 1975 included watertight subdivisions, but most could not prevent flooding of the entire cargo hold area.

A fathometer was not required by USCG regulations, and the Edmund Fitzgerald did not have one, even though they were available when the ship sank. Instead, the Edmund Fitzgerald used a hand line to measure water depth. The line had knots at measured intervals and a lead weight on the end. It was thrown over the ship’s bow, and the number of knots counted the depth. The NTSB concluded a fathometer would have given the Edmund Fitzgerald more 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 hard or impossible to reach the hatches from the spar deck (the deck above the cargo holds). The USCG Marine Board found 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 Edmund Fitzgerald lacked a draft-reading system, so the crew had no way to know if the ship had lost freeboard (the level of the 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 and the reduced freeboard decreased the ship’s critical reserve buoyancy. The Edmund Fitzgerald, once described as a “good riding ship,” became slower and less responsive in heavy seas. Its bow tilted to one side or the other without recovering and made a groaning sound not heard on other ships. Captain McSorley described the ship’s movement as a “wiggling thing” that scared him.

NTSB investigators noted the Edmund Fitzgerald’s earlier groundings might have caused undetected damage that led to structural failure during the storm. Great Lakes vessels were normally drydocked for inspection only once every five years. It was also claimed that Captain McSorley did not keep up with routine maintenance or ensure required work was done, unlike the ship’s 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, said, “the hull was just being held together with patching plates.” Questions were raised about why the USCG did not discover and fix issues during its pre-November 1975 inspection, given the poor condition of the ship’s hatch coamings, gaskets, and clamps.

On the evening of November 10, 1975, McSorley said he had never seen bigger seas in his life. Paquette, captain of the Wilfred Sykes, said, “I’ll tell anyone that it was a monster sea washing solid water over the deck of every vessel out there.” The USCG did not advise all ships to seek safe anchorage until after 3:35 p.m. on November 10, many hours after the weather was upgraded from a gale to

Legal settlement

Under maritime law, ships are subject to the rules of the admiralty courts in 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 governed by U.S. admiralty law. The ship’s financial loss, valued at $24 million, was the largest in the history of Great Lakes sailing. Along with the ship, 26,116 long tons (29,250 short tons; 26,535 metric tons) of taconite also sank. Two widows of crew members filed a $1.5 million lawsuit against the ship’s owners, Northwestern Mutual, and its operators, Oglebay Norton Corporation, 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 limit its legal responsibility to $817,920 in connection with other lawsuits by families of crew members. The company paid compensation to surviving families about 12 months before official findings about the probable cause of the sinking, but required the families to sign confidentiality agreements. Robert Hemming, a reporter and newspaper editor, wrote in his book about Edmund Fitzgerald that the U.S. Coast Guard’s conclusions avoided placing blame on 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 related to load lines, keeping water out of ships, search and rescue efforts, life-saving equipment, crew training, loading manuals, and providing 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). The following actions and USCG regulations were implemented based on these recommendations:

• In 1977, the USCG required all ships over 1,600 gross register tons to use depth finders.
• Since 1980, survival suits have been required in each crew member’s quarters and work area, with strobe lights attached to life jackets and survival suits.
• A LORAN-C navigation system was used on the Great Lakes starting in 1980 and later replaced with the Global Positioning System (GPS) in the 1990s.
• Emergency Position Indicating Radio Beacons (EPIRBs) are now installed on all Great Lakes vessels to help locate them quickly during emergencies.
• Navigational charts for northeastern Lake Superior were updated for greater accuracy and detail.
• NOAA changed its method for predicting wave heights.
• The USCG canceled a 1973 rule that allowed ships to carry cargo with less freeboard (space above water).
• The USCG started an annual inspection program in the fall, checking hatch and vent closures and life-saving equipment on all U.S. ships.

Karl Bohnak, a meteorologist from the Upper Peninsula, wrote a book about 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 event changed how people handled severe weather. He explained, “After that, when a gale came up, we dropped the anchor. We dropped the anchor because people learned that large ships could sink.” Mark Thompson wrote, “Since the Fitzgerald sank, some captains may be more likely to anchor during severe storms instead of sailing through them, but many still claim to be skilled in heavy weather sailing.”

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 Gordon Lightfoot, the singer who wrote a song about the wreck, died on May 1, 2023, the church rang its bell 29 times for the crew and one additional time for Lightfoot.

The ship's bell was recovered from the wreck on July 4, 1995. A replica with the names of the 29 sailors who died was placed on the wreck to replace the original. A legal agreement signed by 46 relatives of the deceased, church officials, and the Great Lakes Shipwreck Historic Society (GLSHS) gave GLSHS the responsibility to care for and protect the bell. The agreement required GLSHS to keep the bell in a permanent memorial at Whitefish Point, Michigan, to honor the 29 men who died on the SS Edmund Fitzgerald. It also forbade selling, moving, or using the bell for commercial purposes. If the terms were broken, the bell would be returned to Mariners' Church.

In 1995, a worker in St. Ignace, Michigan, removed the protective coating on the bell, which had been applied by experts from Michigan State University. This caused controversy. In 1996, the Great Lakes Shipwreck Museum tried to display the bell as part of a traveling exhibit, but relatives of the crew objected, calling it a "traveling trophy." As of 2005, the bell is on display at the Great Lakes Shipwreck Museum in Whitefish Point, Michigan.

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

On August 8, 2007, a Michigan family found a life-saving ring on the Keweenaw Peninsula, Lake Superior. It had markings different from those at the wreck site and was initially thought to be 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 made it as a personal memorial.

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

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

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 felt the mistake dishonored the 29 crew members who died. His song helped make the Edmund Fitzgerald's sinking one of the most well-known disasters on the Great Lakes. The song's lyrics differ slightly from the actual events, such as stating the ship's destination as Cleveland instead of Detroit. Lightfoot later changed some lines in live performances based on new information.

On May 2, 2023, Mariners' Church 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 a musical called Ten November to honor the Edmund Fitzgerald's sinking. In 2005, the play was revised into a concert version titled The Gales of November, which premiered on the 30th anniversary of the sinking at the Fitzgerald Theater in St. Paul, Minnesota.

In 2000, Shelley Russell opened a production of her play Holdin' Our Own: The Wreck of the Edmund Fitzgerald at the Forest Roberts Theatre on the campus of Northern Michigan University. The play 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 sinking has become widely known, leading to many memorials and items for sale across the Great Lakes region. These include decorations, clothing, videos, and other items that honor the ship and its loss.
