G'day from Australia.I recently heard the song 'Wreck of the Edmund Fitzgerald' & was taken back to a Detroit visit in 1984 to meet family there.My Aunt was a war bride!
I traveled the lakes & understand well the term "Great" & have seen the grand majesty of these wonders! Could you if possible please pass on Mine & my family's warmest condolences & prayers to the families of the S.S Edmund Fitzgerald. Let it be known that there are people who live way down under the globe who hold this place in there hearts! Thank you.

Stern-Mounted Balanced Rudder - Symmetrical
(NACAOO)


CRA
Link to Infomation . Link to Information

Rudders are shaped so as to minimize hydrodynamic drag. A rudder operates by redirecting the fluid pasting the hull, thus imparting a turning motion to the boat.
The rudder and propeller was undamaged with the rudder position lock in at 10 degrees from centerline.This 10 degrees rudder position will turn the Fitz to Port while on a T125 heading for White Fish Bay. The Fitz broke up as the winds and waves were from the west puting heavy pressure on the Fitz weeken hull.

The white painted draft marks are 6" tall and 6" o.c. space apart.
The 19 ft. draft mark is center over a welded seam in the hull plate.
Note: 6" change in a draft mark = 810 Tons

There are 60 minutes in a degree and 60 seconds in a minute; 3600 seconds in a degree. There are 360 degrees in a complete circle or sphere but in all longitude and latitude measurements, the total of the degrees is expressed as 2 halves from 0 to 180 degrees each side.


Temperature on Poop Deck

A worker at Burlington Northern Railroad Dock No. 1 Superior WI heard some chirps from a Cricket located on top of the poop deck of the S.S. Edmund Fitzgerald November 9, 1975. He took count the number of chirps in 5 Seconds that told him the temperature on the Fitz deck that time of day. He noted at 2:15 PM as the Fitz completed it's loading and the drafts was taken, the cricket on the Fitzgerald chirp ten time in five seconds that told him the temperature was 70 degrees fahrenheit on the poop deck. He said the chirps of a cricket that are aboard the boats in the Great Lakes goes like this.

).
If a chirping cricket can tell us the temperature on the Edmund Fitzgerald poop deck,
then can the location of birds sitting on the boat tell us more about the frequency and the amplitude of the vibrating movement of the boat?

Speed of Sound from the stern break to pilot house
The speed of sound is dependent on the density of the air. The density of the air is dependent on the temperature of the air.

The FITZGERALD was a conventional "straightdecker" Great Lakes bulk cargo vessel. It was 729 feet long, 75 feet in breadth, 39 feet in depth. There were 21 cargo hatch openings. Each opening measured 11 feet longitudinally and 48 feet transversely and had a 24-inch coaming above the weather deck.
The Edmund Fitzgerald wreck hull shows two breaks -
Stern break left 253 ft. intack and the Bow break left 276 ft. intack with the Center 200 ft. section destroyed.
The center section destroyed was 200 ft long X 75 ft. wide X 39 ft. tall, made of steel.

Edmund Fitzgerald 729 ft long - The Stern break broke 253 ft. from the back -
The Captain Location was 35ft. from the point at the Bow.
The pilot house crew was 441 ft away from the stern break @ 40 degrees Fahrenheit = 0.4023 second for the sound of the hull break to travel and be heard by the pilot house crew.

Military & Civilian Time Designations
From Time Zone A - Z
There are 25 integer World Time Zones from -12 through 0 (GMT) to +12. Each one is 15° of Longitude as measured East and West from the Prime Meridian of the World at Greenwich, England. Some countries have adopted non-standard time zones, usually 30 minutes offset which have a * designation.

Each Time Zone is measured relative to Greenwich, England. There are both civilian designations which are typically three letter abbreviations (e.g. EST) for most time zones. In addition there are military designations. These use each letter of the alphabet (except 'J') and are known by their phonetic equivalent. E.G. Greenwich Mean Time (civilian) or Z = Zulu (military and aviation).

Michigan is in the Eastern Time Zone in the United States of America (USA). Eastern Standard Time (EST) is 5 hours behind Greenwich Mean Time (GMT-5).Winter Only.
The United States spans 6 time zones. It shares the main four time zones with Canada (Eastern Time, Central Time, Mountain Time and Pacific Time).

UTC uses a 24-hour system of time notation. "1:00 a.m." in UTC is expressed as 0100, pronounced "zero one hundred." Fifteen minutes after 0100 is expressed as 0115; thirty-eight minutes after 0100 is 0138 (usually pronounced "zero one thirty-eight"). The time one minute after 0159 is 0200. The time one minute after 1259 is 1300 (pronounced "thirteen hundred"). This continues until 2359. One minute later is 0000 ("zero hundred"), and the start of a new UTC day.
Coordinated Universal Time (UTC)
International Telecommunication Union

Beginning in the 1920s, nautical time zones were referred to with alphabetic characters. The Z zone is equivalent to Coordinated Universal time (UTC), which is the time at the prime or "zero" meridian (0° longitude). The phonetic alphabet refers to Z as "Zulu". It is still used some settings (i.e. military, nautical and aviation) to refer to UTC.


Caribou Island is an uninhabited island in the eastern end of Lake Superior. It lies entirely within the territorial waters of Canada although only about three miles from the international border between Canada and the United States.

Converting Latitude/Longitude Coordinates
Chart

Fractions of degrees are broken down into minutes and seconds. Each minute represents 1/60th of a degree and each second represents 1/60th of a minute (or 1/3600th of a degree). Below are the steps of converting from an angle in degrees-minutes-seconds to decimal degrees and back to degrees-minutes-seconds.

Converting Degrees, Minutes, Seconds to Decimal Format

latitude and longitude in a decimal format: 46.9972
latitude and longitude in degree, minute, second format: 46deg, 59min, 50sec

To convert coordinates from degrees, minutes,
seconds format to decimal format, use this easy formula:

degrees + (minutes/60) + (seconds/3600)

The example coordinate above would be calculated as:

46 + (59/60) + (50/3600) = 46.9972
or
46 + (.9833) + (.0139) = 46.9972

---------------------------------------------------------------------------------------

Process for Converting Latitude/Longitude Coordinates:
D = Degrees
M = Minutes
S = Seconds
.m = Decimal Minutes
.s = Decimal Seconds

DM.m = Degrees, Minutes, Decimal Minutes (eg. 45o 22.6333)
D.d = Degrees, Decimal Degrees (eg. 45.3772o)
DMS = Degrees, Minutes, Seconds (eg. 45o 22' 38")


(1) DMS --> DM.m (45o 22' 38" --> 45o 22.6333)

- Divide S by 60 to get .m (38/60=.6333)
- Add .m to M to get M.m (22+.6333=22.6333)

(2) DM.m --> D.d (45o 22.6333 --> 45.3772)

- Divide M.m by 60 to get .d (22.6333/60=.3772)
- Add .d to D to get D.d (45+.3772=45.3772)

(3) D.d --> DM.m (45.3772 --> 45o 22.6320)

- Multiply .d by 60 to get M.m (.3772*60=22.6320)

(4) DM.m --> DMS (45o 22.6320 --> 45o 22' 38")

- Multiply .m by 60 to get S(.6320*60=38)


 

Michigan is a state in the United States. The name is derived from Lake Michigan, which in turn is believed to come from the Chippewa Indian word meicigama, meaning "great water."

Bounded by four of the Great Lakes, Michigan has the longest freshwater shoreline in the continental United States.

Distance 70.058 Nautical Miles or 80.621 Statute Miles

Time Calculated by Distance and Speed
80.621 Statute Miles @ 16.3 Statute Miles per Hour = 4 Hours 56 Minutes 45 Seconds
Michipicoten the White Fish Point = Five Hours
Note: The Fitz was reported to pass Michipiconten Island at 1:45 pm and was loss aroung 7:30 pm.
The Fitz sank short of White Fish Bay by One Hour or 16 miles
T144 Does not work.

Test Two: Michipicoten Island West End to Wreck site of Edmund Fitzgerald
Initial Course 141.543 Degrees True
Distance 55.945 Nautical Miles or 64.380 Statute Miles
64.380 Statute Miles @ 16.3 Statute Miles per Hour = 3 Hours 56 Minutes 58 Seconds
Note: The Fitz was reported to pass Michipiconten Island at 1:45 pm and was loss aroung 7:30 pm.
True test time just under 4 Hours - But it took Fitz 5 Hours and 45 Minutes
That 1 Hour and 45 Minutes too long. or the Fitz travel a longer Western trackline near Caribou Island also supports the reports by the Anderson Captain and Mates. Fitz would have to add 28.52 Statute Miles to the T141 trackline to make it work.
T141 Does not work.

Test Three - The Real Track Line: CRA Hydrography Service 2010

The Anderson was reporting only 15 miles behine the Fitz most of the trip. If the Fitz "Check-down" at 3:30 pm to a complete stop to let the Anderson close the distance between the vessels. The Anderson could run into the back of the Fitz in only 1 Hour 1 Minute and 38 Seconds at the reported speed of 14.6 mph.
The Anderson would be one hour behine at 15 Miles.

When looking at a map, latitude lines run horizontally. Latitude lines are also known as parallels since they are parallel and are an equal distant from each other. Each degree of latitude is approximately 69 miles (111 km) apart; there is a variation due to the fact that the earth is not a perfect sphere but an oblate ellipsoid (slightly egg-shaped).

The vertical longitude lines are also known as meridians. They converge at the poles and are widest at the equator (about 69 miles or 111 km apart). Zero degrees longitude is located at Greenwich, England (0°).

Latitude is still measured in degrees, minutes and seconds. A degree of latitude is still around 69 miles (111 km) while a minute is approximately 1.15 miles (1.85 km). A second of latitude is just over 100 feet (30 m).

16.1 MPH is the Typ. speed for the Fitz with a load in bad weather

Lighthouse - 48 06 42.25 N - 86 04 00.09 W

In 1975, the keeper at this remote station watched the freighter EDMUND FITZGERALD pass by in a storm. The ship was wrecked in the storm, with no survivors. The island is within Pukaskwa National Park. Next: Set the heading for Caribou Island Radio Beacon. This heading would have the Fitz pass by Michipicoten Island west end by 2.5 miles out as stated in the official reports. This is a good plan heading for the upcoming weather conditions that the Fitz would be in.

Significantly, within a few minutes of passing the mark and unmarked shoals, the Fitzgerald Captain Ernest McSorley reported a port list, missing vents and a fence rail down. Beyond that, Captain “Bernie” Cooper and Morgan Clark of the Anderson commented that his radar showed the - "Fitzgerald to be closer to the shoal than he wanted his ship to be".

White Fish Point Light was out

After passing Caribou Island on the East side, Set the heading for White Fish Point Radio Beacon, but it's light and radios are out. Ask Anderson for help with upbound traffic because the Fitz radars are out as the Fitz line up for White Fish Bay. T125 take you there. Entrance of Whitefish Bay from the south end of Caribou Island in Lake Superior. Tip of Whitefish Point, north of Paradise, Michigan. Hold true to T125 and there is a Light Beacon right on this heading as you get close to guild the Fitz to the center of White Fish Bay that has a safe harbor with sandy beaches if needed. The T125 will also help the boat travel better with the west winds and west waves in the storm. With a bad list, taking on water and a damage boat, no dangerous row in turns on the way to White Fish Bay would be required. The next best working radio beacon is on Copper Mine Point light and this would also be a good heading to get down by White Fish Bay.

Racon system was not working.

A Racon is a radar transponder commonly used to mark maritime navigational hazards. The word is an acronym for RAdar beaCON.
When a racon receives a radar pulse, it responds with a signal on the same frequency which puts an image on the radar display. This takes the form of a short line of dots and dashes forming a Morse character radiating away from the location of the beacon on the normal plan position indicator radar display. The length of the line usually corresponds to the equivalent of a few nautical miles on the display.Also to identify centre lines and turning points

Racons usually operate on the 9320 MHz to 9500 MHz marine radar band

 

The Fitz plow a trench hunderds of feet long in to the lake bottom with a forward heading left in the mud of T125 as noted in the official report.

T125 Heading for safe anchor

Fitz could line up on a T125 heading using Caribou Island radio signal heading to line up with the center line of White Fish Bay on the down bound run. T125 heading is the better angle because of the west winds and west wave action on the damage boat. They would had only 14.85 Nautical Miles to go from where the Fitz sank.

Lighted fixed aids are structures equipped with a light and located at prominent sites to assist the mariner to fix his position. They may be at or near shorelines or on built up, man made piers in or near waterways. The structure and colour(s) of lighted fixed aids are often selected for maximum visibility and ease of identification and may or may not have lateral significance. Lightstations are coastal landfall lights that have distinctive characteristics to assist the mariner in determining his exact location.

Inside the S.S. Edmund Fitzgerald

The FITZGERALD was a conventional "straightdecker" Great Lakes bulk cargo vessel. It was 729 feet long, 75 feet in breadth, 39 feet in depth, 13,632 gross tons, and 8,686 net tons. It was propelled by a 7,500-hp, steam turbine and was built as Hull 301 at Great Lakes Engineering Works, River Rouge, Michigan, in 1958. The vessel was owned by Northeastern Mutual Life Insurance Company and operated by the Columbia Transportation Division of the Oglebay Norton Company.

S.S. Edmund Fitzgerald Hull 301
4,000 ft of cracking was detected in the keelson and frames

Some 4,000 ft. of cracking was detected in the keelson and frame connection to the shell plating; however, during the winter layup of 1968-1969, this condition was look at and a minimum redesign and repair was done to get a coast guard approval to get the boat back in service that year. Each year the cracking came back.The mud layer in the bottom of the ballast tanks would make it hard to inspect for this problem each year.

Force of Freezing Water

Water's Chemical Properties
Water's chemical description is H2O. As the diagram to the above shows, that is one atom of oxygen bound to two atoms of hydrogen. The hydrogen atoms are "attached" to one side of the oxygen atom, resulting in a water molecule having a positive charge on the side where the hydrogen atoms are and a negative charge on the other side, where the oxygen atom is. Since opposite electrical charges attract, water molecules tend to attract each other, making water kind of "sticky." As the bottom diagram shows, the side with the hydrogen atoms (positive charge) attracts the oxygen side (negative charge) of a different water molecule.

A water molecule can form a maximum of four hydrogen bonds because it can accept two and donate two hydrogen atoms.

Water expands slightly until it reaches the freezing point, and then when it freezes it expands by approximately 9%.

There are 3 states of water which are liquid, solid and gas. All three states exist on earth. Water has been called the life force. There are names for each of the phase changes of water. They are given below:

The following table gives the density of water in grams per cubic centimeter at various temperatures in degrees Celsius:
Temperature Converter = 32 Fahremheit = 0 Celsius
Tc = (5/9)*(Tf-32); Tc = temperature in degrees Celsius, Tf = temperature in degrees Fahrenheit
The Celsius temperature scale is still sometimes referred to as the "centigrade" scale. Centigrade means "consisting of or divided into 100 degrees;" the Celsius scale, devised by Swedish Astronomer Andres Celsius (1701-1744) for scientific purposes, has 100 degrees between the freezing point (0 C) and boiling point (100 C) of pure water at sea level air pressure. The term Celsius was adopted in 1948 by an international conference on weights and measures.

The values below 0 °C refer to supercooled water

Water is much heavier than air. A cubic foot of air weighs 1/12 pound (lb). A cubic foot of fresh water weighs 62.4 lbs and a cubic foot of sea water weighs 64 lbs.

Water (n) a liquid substance (formula: H2O) formed by the combination of hydrogen and oxygen.
1 atmosphere = 760 mmHg = 29.92 inHg = 14.7 lb/in2 = 101.3 KPa
Atmospheric pressure is the force per unit area exerted against a surface by the weight of air above
that surface in the 50 mile high Earth's atmosphere.

Air pressure decreases with altitude and water pressure increases with depth.

The S.S. Edmund Fitzgerald sank 530 ft. to the bottom.

Pressure increases at the rate of 1 ATM every 33 feet of water depth.
A diver at 33 feet of depth is at 2 ATM, 3 ATM at 66 feet, and so on.

Air volume in a flexible space (such as your lungs and sinuses) is reduced proportionate to pressure. At 2 ATM the volume is halved, at 3 ATM it is a third of surface volume, and so on.

Air within an air space will expand proportionally as pressure is reduced. For example, moving from 2 ATM to 1 ATM (33 feet underwater to the surface), air in a closed container will double.

The United States Search and Rescue Task Force has a risk list for when hypothermia
might set in if you are submersed in water:

Water temperature: 32.5 to 40 degrees
Time until exhaustion or unconsciousness: 15 to 30 minutes
Expected time of survival in the water: 30 to 90 minutes

About 1530, the FITZGERALD, then in a position northeast of Caribou Island, called the ANDERSON and reported, "I have a fence rail down, have lost a couple of vents, and have a list." The FITZGERALD further advised that she would ‘‘check-down’’ to allow the ANDERSON to close the distance between the vessels. The ANDERSON asked the FITZGERALD if the pumps were going and the reply was, "Yes, both of them."

Loading was completed about 1415 on November 9. The chief mate informed dock personnel that the vessel’s final drafts were 27 feet 2 inches forward and 27 feet 6 inches aft. Drafts were taken after receipt of the taconite pellets and 50,013 gallons of No. 6 fuel oil, delivered by a barge which came alongside while the cargo was being loaded.

Great Lakes bulk carriers are loaded to have as little trim, heel, and midship deflection as possible. Cargo is distributed so that the vessel does not hog; however, 1 inch of sag is considered acceptable.


About 1915 EST on November 10, 1975, the Great Lakes bulk cargo vessel SS EDMUND FITZGERALD, fully loaded with a cargo of taconite pellets, sank in eastern Lake Superior in position 46 59.91 N, 85 06.61 W, approximately 17 miles from the entrance to Whitefish Bay, MI. The ship was en route from Superior, WI, to Detroit, MI, and had been proceeding at a reduced speed in a severe storm.

"The position of FITZGERALD relative to that of ANDERSON cannot be reconstructed. Information available is based on the recollections of the Master and Watch Officers on ANDERSON, since the relative position of FITZGERALD was observed intermittently on the radar, but not recorded. Testimony on these observations is inconsistent.

Wreckage identified as that of the FITZGERALD was located in position 46 59.91' N, 85 06.61’ W in 530 feet of water in eastern Lake Superior just north of the International Boundary in Canadian waters. This position correlates with the last position of the FITZGERALD as reported by the ANDERSON.

 


American Bureau of Shipping
1865 - 2010

The American Bureau of Shipping was officially recognized by the
United States government in the Merchant Marine Act of 1920. The legislation
required that, in work involving a classification organization, every governmental agency in the United States would turn to ABS.

LOAD LINE CERTIFICATES
A Load Line Certificate is issued on behalf of an
Administration to indicate that a vessel is capable of carrying
its intended cargo in a stable condition. The load line itself is a
hull mark that indicates the maximum draft to which a vessel
is permitted to safely load.


1973 - PRESQUE ISLE,
a tug-barge combination designed for Great Lakes Service,
is over 1,000 feet long.


1980
WORLD’S LARGEST MERCHANT SHIP CLASSED BY ABS
A1,504-foot tanker, the world’s
largest merchant ship, was built
to ABS class in 1980.

The growth in the size of vessels – tankers, bulk carriers and containerships alike – took
designers and classification societies into new territory for which there were no
empirical guidelines. Innovation led to the development of composite vessels such as
ore-bulk-oil (OBO) carriers; specialist roro car carriers; open hatch bulk carriers,
designed for the efficient carriage of forest products; and a host of other specialist
carriers. It marked the demise of the traditional general cargo ship that had been the
mainstay of every shipping fleet.

1973 Freeboard is again reduced by ABS. The S.S. Edmund Fitzgerald can now legally carry enough cargo to sit 3 feet 3 1/4 inches lower in the water than was considered safe when she was launched. (4,421.5 tons more.) The shipping industry standard for shipments of coal is the net ton (2,000 lbs or 907.2 kgs). Other bulk commodities use the gross ton (2,240 lbs / 1,016 kgs) or metric tonne (1,000 kgs / 2,204.6 lbs).

Between 1958 and 1973, the FITZGERALD was permitted three reductions in the minimum freeboard required by 46 CFR Part 45. (Freeboard on the FITZGERALD was the distance from the maximum draft permitted to the weather deck at side.)

As part of the requirements for obtaining the freeboards assigned on September 13, 1973, all vents were to be at least 30 inches above the weather deck. However, under 46 CFR 45.133(b), the FITZGERALD was permitted to have ballast tank vents extending to only 18 inches above the weather deck because the 30-inch height interfered with handling cargo on the ship.

Some 4,000 ft. of cracking was detected in the keelson and frame connection to the shell plating; however, during the winter layup of 1968-1969, this condition was look at and a minimum redesign and repair was done to get a coast guard approval to get the boat back in service that year.

The FITZGERALD was a conventional "straightdecker" Great Lakes bulk cargo vessel. It was 729 feet long, 75 feet in breadth, 39 feet in depth, 13,632 gross tons, and 8,686 net tons. There were 21 cargo hatch openings. Each opening measured 11 feet longitudinally and 48 feet transversely and had a 24-inch coaming above the weather deck.


Working Stress, Allowable Stress, and Factor of Safety
Stress is produced by forces

MEMORIES

M = Moment & F = Concentrated force on hull (N)
Working stress is defined as the actual stress of a material under a given loading. The maximum safe stress that a material can carry is termed as the allowable stress. The allowable stress should be limited to values not exceeding the proportional limit. However, since proportional limit is difficult to determine accurately, the allowable stress is taken as either the yield point or ultimate strength divided by a factor of safety. The ratio of this strength (ultimate or yield strength) to allowable strength is called the factor of safety.

Structural steels are normally ductile but become brittle at low temperatures.

Suppose that a metal specimen from the Edmund Fitzgerald be placed in tension-compression-testing machine. As the axial load is gradually increased in increments, the total elongation over the gauge length is measured at each increment of the load and this is continued until failure of the specimen takes place. Knowing the original cross-sectional area and length of the specimen, the normal stress and the strain can be obtained. The graph of these quantities with the stress along the y-axis and the strain along the x-axis is called the stress-strain diagram. The stress-strain diagram differs in form for various materials. The diagram shown below is that for a medium-carbon structural steel. Metallic engineering materials are classified as either ductile or brittle materials. A ductile material is one having relatively large tensile strains up to the point of rupture like structural steel and aluminum, whereas brittle materials has a relatively small strain up to the point of rupture like cast iron and concrete. An arbitrary strain of 0.05 mm/mm is frequently taken as the dividing line between these two classes.

Structural steels become brittle at low temperatures and there is a change in the mechanism of fracture. There is little deformation of the sample and the grains in the microstructure fail along certain crystal planes. This is known as cleavage.

Structural steels are normally ductile but become brittle at low temperatures. There is a lot of deformation of the sample and the grains in the microstructure fail by void formation as the metal flows around hard particles in the microstructure. This is known as microvoid coalesence.

Steel is an alloy composed of iron and carbon--the higher the carbon content, the stronger, harder and more brittle the steel. There are many types of steel, all of which are categorized based upon various physical properties and carbon content. High carbon steel is very strong and it is used for files, cold chisels and various metal tools while low carbon steel is used for tubing, nails and castings.

Preheating the base metal before welding is an important defense against rapid cooling and can help reduce hydrogen levels; both are factors that can lead to cracking. The material to be preheated and its thickness determine the proper preheat temperature

Welding short, small fillet welds also can reduce heat input and overall residual stresses on the AR plate to help minimize cracking.


Kestner Clamps
Used on Great Lake vessels to secure there large hatch covers.

Another good weather day in November
Each hatch cover could be secured by 68 manually operated "Kestner" clamps arranged on 2-foot centers.

12 Kestner clamps was used per hatch cover on good weather day to day runs, using two clamps at each corner and two in the middle of each long side. If loading was done on a weekend, the Monday shift would finish the clamping down to avoid any overtime pay from a weekend loading. The Fitz left Sunday November 9, 1975 at 2:15 PM in good weather and would have to pay company overtime if they didn't finish clamping all of the Kestner clamps on that weekend in good weather. The next day, the Fitz receipt of storm warnings at 2:00 AM.

On November 10, the storm was located over central Wisconsin, had a minimum barometric pressure of 29.24 inches of mercury and was moving at an average speed of 29 knots. At 0100 on November 10, the FITZGERALD was about 20 miles south of Isle Royal and reported winds from 030 T at 52 knots and waves of 10 feet.
The Fitz at 0200 reported that he must slow down to haft speed because the boat was working to hard in only 10 ft seas. The Fitz was steering 45d and turning haft speed at Royal Island. The Anderson just ahead of the Fitz was turning 85 rpm and was steering good.

Curv III

CABLE-CONTROLLED UNDERWATER RECOVERY VEHICLE

The vehicle pictured at bottom was the first successful remotely operated undersea vehicle. The Cable-controlled Undersea Recovery Vehicle (CURV) was developed in the early 1960's by the former Pasadena Annex of the Naval Ordnance Test Station, one of SSC San Diego's parent laboratories. CURV was designed to recover test ordnance lost off San Clemente Island at depths as great as 2000 feet, but became famous in 1966 with the recovery of an H-bomb off Spain in 2800 feet of water. This sucesss spawned later generations of vehicles designated CURV II, CURV II-B, CURV II-C and CURV III. CURV, now referred to as CURV I, pioneered the concept of undersea teleoperators.

At that time, a task force was formed, including representatives from the Coast Guard Marine Board of Investigation, the National Transportation Safety Board, the U.S. Navy Supervisor of Salvage, the Naval Undersea Center, and Seaward, Inc. of Falls Church, Virginia, an engineering consultant firm under contract to the U.S. Navy Supervisor of Salvage to make a visual survey of the wreckage using the USN CURV III System under contract to the USCG. The CURV III is an unmanned, deep-diving vehicle controlled from the surface and capable of television and still photography. This vehicle made 12 dives with a total of 56 hours 5 minutes bottom time and recorded 43,255 feet of videotape and 985 still color photographs.

Six-Fathom Shoal Updates

During a taped conversation with his office, which was made a part of the record, the ANDERSON’s master stated that the FITZGERALD "passed right over that 6-fathom spot." The Canadian Hydrographic Service survey shows the water depth at this charted "6- fathom spot". If the FITZGERALD, whose draft was more than 27 feet, had passed through this position on a course plan later that day of 141 T the vessel would have had to pass over the north tip of Caribou Island and through an area where the depth is less than 21 feet.

Marine Casualty Report
46 59.9 N 85 06.6 W

Wreckage identified as that of the FITZGERALD was located in position 46 59.91 N’, 85 06.6’ W in 530 feet of water in eastern Lake Superior just north of the International Boundary in Canadian waters. This position correlates with the last position of the FITZGERALD as reported by the ANDERSON.

The wreckage lies approximately 17 miles northwest of Whitefish Point, Michigan. The wreckage consists of an upright bow section, an inverted stern section, and debris from a missing 200-foot midship portion. The bow section is 276 feet long, inclined 15 degrees to port from the upright, extends from the stem to a location between hatches Nos. 8 and 9, and is buried in mud up to the 28-foot draft mark.

Canadian Chart 2310, "Lake Superior, Caribou Island to Michipicoten Island," which shows the area from slightly north of Michipicoten Island to slightly south of Caribou Island at a scale of 1:97,280 is published by the Canadian Hydrographic Service.

After this accident, the Coast Guard requested the Canadian Hydrographic Service to conduct a hydrographic survey of the area north of Caribou Island to confirm the charted soundings and to update the charted data. Current charts are based on a survey conducted by the Canadian Hydrographic Service in 1916 and 1919.

Columbia Transportation Division, the operator of the FITZGERALD, conducted an independent hydrographic survey of the shoal area north of Caribou Island. Water depths were determined by sonic devices, lead line, and direct measurement by divers. The results of this survey show water depths that vary slightly from the Canadian survey. These differences can be attributed to the rocks and boulders on the bottom and the various tracklines on which soundings were recorded.

Only three navigational charts covering the area between Michipicoten Island and Whitefish Bay are available. These charts are:

a. Lake Survey Chart No. 9, "Lake Superior," which shows all of Lake Superior at a scale of 1:600,000 published by the U.S. National Oceanic and Atmospheric Administration (NOAA).

Reexamination of the 9–10 November 1975 “Edmund Fitzgerald”
Storm Using Today's Technology

Thomas R. Hultquist
Video - Animation of Storm

There has been considerable debate over the past three decades concerning the specific cause of the loss of the ship the Edmund Fitzgerald on Lake Superior on 10 November 1975, but there is little question that weather played a role in the disaster. There were only a few surface observations available during the height of the storm, so it is difficult to assess the true severity and meteorological rarity of the event. In order to identify likely weather conditions that occurred during the storm of 9–10 November 1975, high-resolution numerical simulations were conducted in an attempt to assess wind and wave conditions throughout the storm. Comparisons are made between output from the model simulations and available observational data from the event to assess the accuracy of the simulations. Given a favorable comparison, more detailed output from the simulations is presented, with a focus on high-resolution output over Lake Superior between 1800 UTC 9 November 1975 and 0600 UTC 11 November 1975. A detailed analysis of low-level sustained wind and significant wave height output is presented, illustrating the severity of the conditions and speed with which they developed and later subsided during the event. The high temporal and spatial resolution of the model output helps provide a more detailed depiction of conditions on Lake Superior than has previously been available.

"The Pressure is on what to say after the Wreck"
At the Marine Board Captain Cooper and Chief Mate Clark both testified
that the FITZGERALD was not near the shoal area.
"Maybe he didn’t go in there (close to Caribou Island)."

Sailing with 4,000 feet of broken bottom welds and the most probable cause of the sinking of the SS EDMUND FITZGERALD in Lake Superior on 10 November 1975, was a shoaling which first generated a list, the loss of two air vents, and a fence wire. Secondarily, within a period of 3 to 4 hours, the detected, progressive, massive flooding of the damage cargo hold from the last unloading resulted in a total loss of buoyancy from which, it broke up and sank to the bottom as the FITZGERALD was to damage to recover.

Six-Fathom Shoal Updates

Perhaps the most widely accepted of the four theories about the loss of the Fitzgerald is that the ship crossed Caribou Island’s Six-Fathom Shoal, which is located off the north end of the island with water as shallow as 26.5 feet. This contact or a near contact could damage the hull plate and allow water to begin accumulating inside the affected port side ballast tanks. Significantly, within a few minutes of passing the mark and unmarked shoals, the Fitzgerald Captain Ernest McSorley reported a port list, missing vents and a fence rail down. Beyond that, Captain “Bernie” Cooper and Morgan Clark of the Anderson commented that his radar showed the -
"Fitzgerald to be closer to the shoal than he wanted his ship to be".

Before 1883 all hydrographic work in Canada was carried out by the British Admiralty under an arrangement whereby, after Confederation, Canada was assessed with half the cost. We have already made a brief mention of Admiral Bayfield who, as Admiralty Surveyor, had spent forty years in the making of Canadian charts before his retirement in 1856. There were few sections along the principal shipping routes from Halifax to the Lakehead which had not been charted under his personal supervision, and "Bayfield Charts" were highly valued by the shipmasters of the day. In course of time, with the increase in numbers and size of steamer traffic on the Great Lakes, the Bayfield charts became inadequate and out of date and, in the late seventies, the Department of Marine and Fisheries began to receive complaints.

Columbia Transportation Division, the operator of the FITZGERALD, conducted an independent hydrographic survey of the shoal area north of Caribou Island. Water depths were determined by sonic devices, lead line, and direct measurement by divers. The results of this survey show water depths that vary slightly from the Canadian survey. These differences can be attributed to the rocks and boulders on the bottom and the various tracklines on which soundings were recorded.

The Canadian Hydrographic Service survey shows the water depth at this charted "6-fathom spot" is 52 meters (28.4 fathoms). If the FITZGERALD, whose draft was more than
27 feet, had passed through this position on a course of 141 T the vessel would have had to pass within 3/4 of a mile of the north tip of Caribou Island and through an area where the depth is less than 21 feet.

"The position of FITZGERALD relative to that of ANDERSON cannot be reconstructed. Information available is based on the recollections of the Master and Watch Officers on ANDERSON, since the relative position of FITZGERALD was observed intermittently on the radar, but not recorded. Testimony on these observations is inconsistent.

Despite many people accepting this as the most likely scenario for the sudden list and deck damage, the photographic evidence for such a grounding may exist. Every expedition to the freighter has reported that there is some scraping, gouging or damage to the rudder or propeller, which should show on the overturned bottom of the stern. Diving expeditions on the shoals soon may find new evidence of groundings by a ship.

By the afternoon of the 10th, the Fitzgerald had reached the eastern part of the lake and the Witch of November had been punishing her and the Anderson for 14 hours. At 3:15 p.m., Captain Cooper and the Anderson's First Mate Morgan E. Clark watched the Fitzgerald on their radar as she crossed into dangerous water.

COOPER: "Look at this, Morgan. That's the Fitzgerald; he's in close to that six fathom spot."
CLARK: "He sure looks like he's in the shoal area.²
COOPER: "He sure does. He's in too close. He's closer than I'd want this ship to be."
At six feet to the fathom, Six Fathom Shoals is only 36 feet deep-- dangerous ground for such a big ship in a storm. Shallow water causes wave height to increase dramatically, and a big, heavy freighter like the Fitzgerald can strike bottom in the troughs of big waves.
At 3:30 p.m., Captain McSorley radioed the Anderson:
FITZGERALD: "Anderson, this is the Fitzgerald. I have sustained topside damage. I have a fence rail down, two vents lost or damaged, and a list. Will you stay by me 'til I get to Whitefish?"
ANDERSON: Charlie on that Fitzgerald. Do you have your pumps going?"
FITZGERALD: "Yes, both of them."
Investigators later determined the list was from taking on water either through damaged vents or from striking bottom.
Then, at 4:00 p.m., the Witch unleashed a screaming 87 knot (100 m.p.h.) wind gust on the Anderson-- a gust that continued straight toward the Fitzgerald. Ten minutes later Captain McSorley again radioed the Anderson:
FITZGERALD: "Anderson, this is the Fitzgerald. I have lost both radar's. Can you provide me with radar plots 'til we reach Whitefish Bay?"
ANDERSON: "Charlie on that, Fitzgerald. We'll keep you advised of your position."


Replot the track line from the lost two page report
Safety Board investigators considered the possibility that flooding resulted from a grounding which ruptured the hull plating in the area of some ballast tanks, but rejected this possibility for the following reasons:
A reconstruction of the FITZGERALD’s most probable trackline shows her path to be about 3 miles from the nearest position where grounding could have occurred.

In reconstructing the ANDERSON’s probable trackline, the Safety Board relied primarily upon the ship’s log entries concerning fixes taken at 1520 and 1652, the courses steered, and the reported speed of 14.5 mph. Subsequent testimony indicated a course change at 1652, which was not logged and a fix taken at 1701, which also was not logged.


What cause November 10, 1975 winds?
Pressure gradient
horizontal pressure differences (on a
constant elevation surface) are
responsible for movement of air
always H > L

• pressure differences exits due to unequal heating of surface
• change in pressure per change in distance determines the
magnitude of the pressure gradient force (PGF).
•Greater pressure changes across shorter distances creates a
larger PGF to initiate movement of winds.

S.S. Edmund Fitzgerald Bell
The first bell rang VIDEO

Ships' watches
The shipboard day is divided into 6 watches, each 4 hours long. The day begins at noon. The traditional names of the watches are:

afternoon watch
Noon to 4 pm
evening watch
4 pm to 8 pm
first watch
8 pm to midnight
midwatch or middle watch
Midnight to 4 am
morning watch
4 am to 8 am
forenoon watch
8 am to noon

Unlike civil clock bells, the strikes of the bell do not accord to the number of the hour. Instead, there are eight bells, one for each half-hour of a four-hour watch. Bells would be struck every half-hour, and in a pattern of pairs for easier counting, with any odd bells at the end of the sequence.

The term "Eight bells" can also be a way of saying that a sailor's watch is over, for instance, in his or her obituary. It's a nautical euphemism for "finished".

Ship's bells are also used for safety in foggy conditions, their most important modern use.

The system is:

Number of bells Bell Pattern Hour (a.m. and p.m.)
One bell . 12:30 4:30 8:30
Two bells .. 1:00 5:00 9:00
Three bells .. . 1:30 5:30 9:30
Four bells .. .. 2:00 6:00 10:00
Five bells .. .. . 2:30 6:30 10:30
Six bells .. .. .. 3:00 7:00 11:00
Seven bells .. .. .. . 3:30 7:30 11:30
Eight bells .. .. .. .. 4:00 8:00 12:00

S.S. EDMUND FITZGERALD:
Requiem for the Toledo Express; A Search for Truth
By Raymond Ramsay M.Sc.

A review by Thom Holden, Director
Lake Superior Maritime Visitor Center, Duluth, Minnesota

This is a “must read” book for anyone more than casually interested in the wreck of the Edmund Fitzgerald, lost November 10, 1975, on Lake Superior. Historians are always trying to get back to the beginning and talk with witnesses and participants in the making of history. In the case of the Edmund Fitzgerald's loss with all 29 persons on board, we cannot go back to that night to gather their individual accounts of the loss.

However, we can go even further back in time right to the design and construction of the vessel itself at the Great Lakes Engineering Works at Ecorse, Michigan, and learn from a young, but experienced naval architect trained in England and Canada. That person is the author of this book, Raymond Ramsay. He was there working on the Fitzgerald from keel laying to launch to sea trails and beyond.

Now an elder statesman among naval architects with a distinguished career, Ramsay reveals his thoughts and experiences about the vessel's design, construction, materials, shipyard practices, and more in this fascinating book. Unfettered by the potential of employer retribution and with a lifetime of experience, Ramsey dares to explore many of the unstated questions which have lingered in the shadows of the Edmund Fitzgerald's mystique. Ramsay's ideas are original, yet formed and tested in the give and take of fellow experts, all part of Casualty Research Associates (CRA).
Ramsay notes a strong sense of “keeping to the company line” among the industry and its overseers throughout the investigation. The pre-investigation conclusion was that this casualty was an “Act of God” and totally unforeseeable at the time. He believes there is enough factual evidence gathered in the decades since the casualty and the incomplete nature of the official investigations by the Coast Guard and National Transportation Safety Board to provide legal cause to reopen the investigation, a request which must come from the families who are often bound by commitments made at the time they made financial settlements back in the 1970s.

Ramsay does not portend that he or this book asked all the right questions nor found all the best answers. Still, it is the only reference available from someone who really was there right from the beginning; someone who saw the daily construction, was onboard during sea trials, and kept a close eye on the vessel from beginning to end and beyond.
