Concrete ships are built primarily with ferrocement (reinforced concrete) hulls, reinforced with steel bars. [1] This contrasts against more traditional materials, such as pure steel or wood. The advantage of ferrocement construction is that materials are cheap and readily available, while the disadvantages are that construction labor costs are high, as are operating costs. (Ferrocement ships require thick hulls, which results in either a larger cross-sectional area that hurts hydrodynamics, or leaves less space for cargo.) During the late 19th century, there were concrete river barges in Europe, and during both World War I and World War II, steel shortages led the US military to order the construction of small fleets of ocean-going concrete ships, the largest of which was the SS Selma. [2] United States Maritime Administration (MARAD) designation for concrete ships-barges was Type B ship. Few concrete ships were completed in time to see wartime service during World War I, but during 1944 and 1945, concrete ships and barges were used to support U.S. and British invasions in Europe and the Pacific. Since the late 1930s, there have also been ferrocement pleasure boats. [3] [4]
The oldest known ferrocement watercraft was a dinghy built by Joseph-Louis Lambot in Southern France in 1848. Lambot's boat was featured in the Exposition Universelle held in Paris in 1855.
Beginning in the 1860s, ferrocement barges were built in Europe for use on canals, and around 1896, an Italian engineer, Carlo Gabellini, began building small ships out of ferrocement. The most famous of his ships was the Liguria. [5]
Between 1908 and 1914, larger ferrocement barges began to be made in Germany, United Kingdom, [6] the Netherlands, Norway and United States. [7] The remains of a British ship of this type, the auxiliary coaster Violette (built 1919), can be seen at Hoo, Kent, England. [8]
On August 2, 1917, Nicolay Fougner of Norway launched the first self-propelled ferrocement ship intended for ocean travel. This was an 84-foot (26 m) vessel of 400 tons named Namsenfjord. With the success of this ship, additional ferrocement vessels were ordered, and in October 1917, the U.S. government invited Fougner to head a study into the feasibility of building ferrocement ships in the United States. [9] [10] The Fougner Concrete Shipbuilding Company, Flushing Bay, New York, reported calculated cost was of $290 per deadweight ton for the Cape Fear (List of shipwrecks in 1920 "10.21 30 October") and the Sapona which they presumably built. [5]
About the same time, the California businessman W. Leslie Comyn took the initiative to build ferrocement ships on his own. He formed the San Francisco Ship Building Company (in Oakland, California), and hired Alan Macdonald and Victor Poss to design the first American ferrocement ship, a 6,125-ton steamer named the SS Faith. Faith was launched March 18, 1918. She cost $750,000 to build. She was used to carry bulk cargo for trade until 1921, when she was sold and scrapped as a breakwater in Cuba. [5]
On April 12, 1918, President Woodrow Wilson approved the Emergency Fleet Corporation program which oversaw the construction of 24 ferrocement ships for the war. However, when the war ended in November 1918, only 12 ferrocement ships were under construction and none of them had been completed. These 12 ships were eventually completed, but soon sold to private companies who used them for light-trading, storage, and scrap. [5]
Other countries that looked into ferrocement ship construction during this period included Canada, Denmark, Italy, Spain, Sweden [7] and the United Kingdom. [11]
Between the world wars, there was little commercial or military interest in concrete ship construction. The reason was that other shipbuilding methods were cheaper and less labor-intensive, and other kinds of ships were cheaper to operate. However, in 1942, after the U.S. entered World War II, the U.S. military found that its contractors had steel shortages. Consequently, the U.S. government contracted McCloskey & Company [12] of Philadelphia, Pennsylvania to build 24 self-propelled concrete ships. Construction started in July 1943. The shipyard was at Hookers Point in Tampa, Florida, and at its peak, it employed 6,000 workers. [13] The U.S. government also contracted with two companies in California for the construction of concrete barge ships. [13] Barge ships were large vessels that lacked engines to propel them. Instead, they were towed by tugs.
In Europe, ferrocement barges (FCBs) played a crucial role in World War II operations, particularly in the D-Day Normandy landings, where they were used as part of the Mulberry harbour defenses, for fuel and munitions transportation, as blockships, [14] and as floating pontoons. In 1940, 200 were commissioned to serve as petrol-carrying barges. The barges weighed 160 tons and were constructed on the London dockside before being craned into the water by a giant crane. [15]
Some barges were fitted with engines and used as mobile canteens and troop carriers. Some of these vessels survive as abandoned wrecks or sea defenses (against storm surges) in the Thames Estuary including near Rainham Marshes. [15] ) Two remain in civil use as moorings at Westminster.
One notable wartime FCB, previously beached at Canvey Island, was partially removed in 2003 by the local sailing club, whose land it was on, for fear it was a "danger to children". Local historians disagreed with the club and were displeased with their actions. [16]
In 1944 a concrete firm in California proposed a submarine shaped freighter which they claimed could achieve speeds of 75 knots. The war ended any more research into the project. In retrospect many believe the claims were greatly overstated. [17]
Concrete barges also served in the Pacific during 1944 and 1945. [18] From the Charleroi, Pennsylvania, Mail, February 5, 1945:
Largest unit of the Army's fleet is a BRL, (Barge, Refrigerated, Large) which is going to the South Pacific to serve fresh frozen foods – even ice cream – to troops weary of dry rations. The vessel can keep 64 carloads of frozen meats and 500 tons of fresh produce indefinitely at 12°F. Equipment on board includes an ice machine of five-ton daily capacity and a freezer that turns out more than a gallon of ice cream a minute. Three of the floating warehouses, designed for tropical warfare, have been built of concrete at National City, Calif., and cost $1,120,000 each. In the crew of the 265-ft. barges are 23 Army men.
One concrete barge under tow by Jicarilla (ATF-104) was lost off Saipan during a typhoon, and another barge damaged the Moreton Bay Pile Light in Brisbane, [19] but the rest served admirably. [20]
Modern hobbyists also build ferrocement boats (ferroboats), [21] as their construction methods do not require special tools, and the materials are comparatively cheap. Since the 1960s, the American Society of Civil Engineers has sponsored the National Concrete Canoe Competition. [22]
In Europe, especially the Netherlands, concrete is still used to build some of the barges on which houseboats are built. [23]
Surviving wartime concrete ships are no longer in use as ships. Several continue in use in various forms, mostly as museums or breakwaters.
The largest collection is at Powell River, British Columbia, 49°51′55″N124°33′21″W / 49.865238°N 124.555821°W , where a lumber mill uses ten floating ferrocement ships as a breakwater, [24] known as The Hulks.
The Kiptopeke Breakwater in Chesapeake Bay, Virginia, 37°09′51″N75°59′29″W / 37.164267°N 75.991402°W , is formed by nine sunken concrete ships built in World War II. [25]
SS San Pasqual, a former oil tanker, lies off the coast of Cayo Las Brujas, Cuba, 22°37′24″N79°13′24″W / 22.623439°N 79.22327°W , where it served as a hotel, then as a base for divers. Currently, the San Pasqual is abandoned. [26] [ not specific enough to verify ]
The wreckage of SS Atlantus (commissioned in 1919, sunk in 1926) is visible off Sunset Beach near Cape May, New Jersey, 38°56′40″N74°58′19″W / 38.944322°N 74.972083°W . [26] [ not specific enough to verify ]

The ship was launched the same day Germany signed the Treaty of Versailles, ending the war, so it never saw wartime duty and instead was used as an oil tanker in the Gulf of Mexico. [2]
The SS Palo Alto, a concrete tanker launched on May 29, 1919, was purchased and turned into an amusement pier, and is still visible at Seacliff State Beach, near Aptos, California, 36°58′11″N121°54′50″W / 36.969704°N 121.913947°W . [26] It broke up during a January 2017 storm. [27]
The SS McKittrick, launched in 1921 in Wilmington, North Carolina, later became the SS Monte Carlo, a gaming ship off Coronado, California, that ran aground on December 31, 1936. The wreck is periodically exposed by strong storm tides. [28]
The vessel aground in the surf at Shipwreck Beach on the north shore of Lanai, Hawaii is the wreck of YOG-42, 20°55′17″N156°54′37″W / 20.921299°N 156.910139°W , a concrete gasoline barge built for the US Navy in 1942 and placed in service in 1943. The wreck is often misidentified as a Liberty ship. [29]
The remains of the Col. J. E. Sawyer can be seen near the USS Yorktown in Charleston Harbor, 32°47′56″N79°54′25″W / 32.798761°N 79.906863°W , South Carolina. [30]
The wreckage of the SS Sapona is visible slightly south of Bimini Island in the Bahamas, 25°39′02″N79°17′36″W / 25.65063°N 79.29337°W . It is a popular snorkeling site and boating landmark in the area.
One of the few concrete ships built for but not completed in time to be used in World War I, the SS Crete Boom, lies abandoned in the River Moy, 54°08′08″N9°08′18″W / 54.135515°N 9.138452°W just outside the town of Ballina, County Mayo, Ireland, and is considered of much interest to the area's many tourists. [31]
A concrete barge, the Cretetree, is beached in the harbour of the Isle of Scalpay near Tarbert, Harris, Scotland, 57°52′37″N6°42′00″W / 57.876873°N 6.699965°W . It was built by Aberdeen Concrete Ships, and completed in 1919. [32]
The Purton Hulks, a collection of vessels intentionally beached at Purton during the first half of the twentieth century as a method to prevent coastal erosion, includes eight ferro-concrete barges. 51°44′14″N2°27′21″W / 51.737178°N 2.455798°W [33] [ not specific enough to verify ]
A large collection of abandoned concrete barges are seen at River Thames in Rainham, London. [15] 51°29′55″N0°10′55″E / 51.498608°N 0.18202°E
The wreckage of the Urlich Finsterwalder, a small Nazi-era German tanker, is visible in Dąbie Lake, near Szczecin, Poland. It was sunk during a Soviet air raid on 20 March 1945. In the late 1950s Polish authorities decided to lift it and tow it to another location to be converted into swimming pools, but during that operation it began sinking again, so it was abandoned in shallow water, where it has remained since. [34]
During the German occupation of Greece (1942–1944) during World War II, the German Army built 24 concrete cargo vessels for transporting goods to various Greek islands, including Crete. These were constructed in the Perama shipbuilding area of Piraeus. After the war, many of the vessels were used as piers (e.g., in Rafina, 38°01′19″N24°00′37″E / 38.022056°N 24.010368°E ) and breakwaters (e.g., in Agios Georgios, Methana, 37°38′18″N23°23′40″E / 37.638340°N 23.394544°E ).
Due to the need to deliver necessary raw materials (such as oil, weapons, ammunition, food and drugs) through mined river currents, Adolf Hitler ordered the production of 50 concrete ships for different purposes. Most were concrete barges made for oil transportation from Romania, and needed raw materials that were driven to the Baltic front. A smaller number of ships was intended for transporting food (specializing in cold storages). The most valuable ships were the specialized ship-hospitals, which evacuated seriously wounded and "important" soldiers to German hospitals along rivers.[ citation needed ]
Several concrete ships were aground on the west beach of Iwo To (Iwo Jima) in Japan, 24°46′57″N141°17′35″E / 24.78238°N 141.293095°E , to make a breakwater by the US forces in 1945. [35] Most of them were broken by typhoons but one was used as a pier. [36]
Japan built four concrete ships named Takechi Maru No. 1 to 4 (武智丸) during World War II. After the war, two of them turned into a breakwater in Kure, Hiroshima, 34°16′48″N132°45′23″E / 34.280089°N 132.756295°E .
The Gloucester and Sharpness Canal is a ship canal in the west of England, between Gloucester and Sharpness, completed in 1827. For much of its length the canal runs close to the tidal River Severn, but it cuts off a significant loop in the river, at a once-dangerous bend near Arlingham. It was once the broadest and deepest canal in the world. The canal is 26.5 km long.
The New York Shipbuilding Corporation was an American shipbuilding company that operated from 1899 to 1968, ultimately completing more than 500 vessels for the U.S. Navy, the United States Merchant Marine, the United States Coast Guard, and other maritime concerns. At its peak during World War II, NYSB was the largest and most productive shipyard in the world. Its best-known vessels include the destroyer USS Reuben James (DD-245), the cruiser USS Indianapolis (CA-35), the aircraft carrier USS Kitty Hawk (CV-63), the nuclear-powered cargo ship NS Savannah, and a quartet of cargo-passenger liners nicknamed the 4 Aces.
SS Atlantus is the most famous of the twelve concrete ships built by the Liberty Ship Building Company in Brunswick, Georgia, United States, during and after World War I.
Ferrocement or ferro-cement is a system of construction using reinforced mortar or plaster applied over an "armature" of metal mesh, woven, expanded metal, or metal-fibers, and closely spaced thin steel rods such as rebar. The metal commonly used is iron or some type of steel, and the mesh is made with wire with a diameter between 0.5 mm and 1 mm. The cement is typically a very rich mix of sand and cement in a 3:1 ratio; when used for making boards, no gravel is used, so that the material is not concrete.
The Little Creek-Cape Charles Ferry was a passenger ferry service operating across the mouth of the Chesapeake Bay from the 1930s until 1964. Known also as the Princess Anne-Kiptopeke Beach Ferry or Little Creek-Kiptopeke Beach Ferry, the service connected Virginia Beach, Virginia with Cape Charles on the Eastern Shore of Virginia. Departures from and arrivals to Cape Charles were matched with times of Pennsylvania Railroad passenger trains such as the Del-Mar-Va Express and the Cavalier that operated the length of the Delmarva Peninsula.
William Leslie Comyn was a Californian businessman, shipbuilder and builder of one of the first large concrete ships.
Sun Shipbuilding & Drydock Company (1917–1989) was a major shipbuilding company in Chester, Pennsylvania on the Delaware River.
W. L. Steed was a steam tanker built in 1917–1918 by Bethlehem Shipbuilding Corporation of Quincy for Pan American Petroleum and Transport Company, with intention of transporting oil and petroleum products between Mexican and Gulf ports and the Northeast of the United States. The ship was briefly requisitioned by the US Government during World War I but returned to commercial service in early 1919. The ship was named after William L. Steed, superintendent of the Mexican Petroleum Company of California.
The SS Monte Carlo was a concrete ship launched in 1921 as the oil tanker SS Old North State. It was later renamed McKittrick. In 1932 it became a gambling and prostitution ship operating in international waters off the coast of Long Beach, California, United States, and was relocated to Coronado, California, in 1936. The Monte Carlo was grounded at Coronado on New Year's Day 1937 during a storm; its wreck remains on the beach.
The Purton Hulks or Purton Ships' Graveyard is a number of abandoned boats and ships, deliberately beached beside the River Severn near Purton in Gloucestershire, England, to reinforce the river banks. Most were beached in the 1950s and are now in a state of considerable decay. The site forms the largest ship graveyard in mainland Britain.
SS Selma was an oil tanker built in 1919 by F.F. Ley and Company, Mobile, Alabama. President Woodrow Wilson approved the construction of 24 concrete vessels of which only 12 were actually completed.
The Type B ship is a United States Maritime Administration (MARAD) designation for World War II barges. Barges are very low cost to build, operate and move. Barges were needed to move large bulky cargo. A tug boat, some classed as Type V ships, could move a barge, then depart and move on to the next task. That meant the barge did not have to be rushed to be unloaded or loaded. Toward the end of World War 2, some ships that had not been completed in time for the war were converted to barges. US Navy barges are given the prefix: YWN or YW. Due to shortage of steel during World War II, concrete ship constructors were given contracts to build concrete barges, with ferrocement and given the prefix YO, YOG, YOGN. Built in 1944 and 1945, some were named after chemical elements.
Type C8-class ships are a type of Heavy Lift Barge Carrier. Type C8 ships were the 8th type of ship designed by the United States Maritime Commission (MARCOM) in the late 1960s. As done with the Type C1 ships and Type C2 ships, MARCOM circulated preliminary plans for comment. The design presented was not specific to any service or trade route. Type C8 ships measuring 876 feet (267 m) from stem to stern, and designed to make 16.2 knots.
Rock Island Bridge was a steam cargo ship built in 1919 by Submarine Boat Company of Newark for the United States Shipping Board (USSB) as part of the wartime shipbuilding program of the Emergency Fleet Corporation (EFC) to restore the nation's Merchant Marine. In March 1920 while on her maiden voyage the vessel collided with another steamer and subsequently had to be beached to avoid sinking. She was later abandoned and sold for scrap.
Craig Shipbuilding was a shipbuilding company in Long Beach, California. To support the World War I demand for ships Craig Shipbuilding shipyard switched over to military construction and built: US Navy Submarines and Cargo Ships. Craig Shipbuilding was started in 1906 by John F. Craig. John F. Craig had worked in Toledo, Ohio with his father, John Craig (1838-1934), and Blythe Craig, both shipbuilders, their first ship was built in 1864 at Craig Shipbuilding Toledo. John F. Craig opened his shipbuilding company in Port of Long Beach on the south side of Channel 3, the current location of Pier 41 in the inner harbor, becoming the port's first shipyard. In 1908 Craig Shipbuilding was given the contract to finishing dredging of the Port of Long Beach inner harbor and to dredge the channel connecting it to the Pacific Ocean. In 1917 Craig sold the shipyard to the short-lived California Shipbuilding Company. but then opened a new shipyard next to the one he just sold and called it the Long Beach Shipbuilding Company. The Long Beach Shipbuilding Company built cargo ships in 1918, 1919, and 1920 for the United States Shipping Board.
Naval Base Iwo Jima was a naval base built by United States Navy on the Japanese Volcano Island of Iwo Jima during and after the Battle of Iwo Jima, that started on February 19, 1945. The naval base was built to support the landings on Iwo Jima; the troops fighting on Iwo Jima; and the repair and expansion of the airfields on Iwo Jima. United States Navy Seabee built all the facilities on the island.
Sieling & Jarvis Inc. was a shipping company that operated tanker ships and some cargo ships. Sieling & Jarvis was started by David B. Jarvis and Dick Sieling in New York City. Later David B. Jarvis was the company president and later became the sole owner of Sieling & Jarvis Inc. Mr. Sieling was the vice president and a partner in Sieling & Jarvis. Sieling & Jarvis supported the World War II effort by operating United States owned ships.
McCloskey & Company Shipyard was a ship builder in Tampa, Florida. McCloskey & Company built 38 cargo ships, Type N3 ship for World War II founded in 1942. McCloskey & Company also built type C1-S-D1 concrete ships. Matthew H. McCloskey founded the construction company McCloskey & Company in Philadelphia. McCloskey & Company built the Philadelphia Convention Hall, the Philadelphia Sheraton Hotel, and the Washington D.C. Stadium.
The Tampa shipyard is now Tampa Ship LLC owned by Edison Chouest Offshore.
