112-547: RMS Orontes was a steam ocean liner of the Orient Steam Navigation Company that was launched in 1902 and scrapped in 1925. Orontes was a troop ship in the First World War . In 1922 she was sold for conversion into an exhibition ship, but the venture fell through so Orient Line repossessed her. Orontes was scrapped in 1925. This was the first of two Orient Line ships called Orontes . The second

224-458: A barge -hauler, Charlotte Dundas , for the Forth and Clyde Canal Company . It successfully hauled two 70-ton barges almost 20 mi (32 km) in 6 hours against a strong headwind on test in 1802. Enthusiasm was high, but some directors of the company were concerned about the banks of the canal being damaged by the wash from a powered vessel, and no more were ordered. While Charlotte Dundas

336-610: A boat with a pair of paddlewheels at each end turned by men operating compound cranks. The concept was improved by the Italian Roberto Valturio in 1463, who devised a boat with five sets, where the parallel cranks are all joined to a single power source by one connecting rod, an idea adopted by his compatriot Francesco di Giorgio . In 1539, Spanish engineer Blasco de Garay received the support of Charles V to build ships equipped with manually-powered side paddle wheels. From 1539 to 1543, Garay built and launched five ships,

448-443: A day when travelling at 13 knots (24 km/h; 15 mph). Her maiden outward voyage to Melbourne took 42 days, with one coaling stop, carrying 4,000 tons of cargo. Other similar ships were rapidly brought into service over the next few years. By 1885 the usual boiler pressure was 150 pounds per square inch (1,000 kPa) and virtually all ocean-going steamships being built were ordered with triple expansion engines. Within

560-560: A demonstration project for the potential use of nuclear energy. Thousands of Liberty Ships (powered by steam piston engines) and Victory Ships (powered by steam turbine engines) were built in World War II. A few of these survive as floating museums and sail occasionally: SS  Jeremiah O'Brien , SS  John W. Brown , SS  American Victory , SS  Lane Victory , and SS  Red Oak Victory . A steam turbine ship can be either direct propulsion (the turbines, equipped with

672-626: A double-hulled boat that was propelled on the Firth of Forth by men working a capstan that drove paddles on each side. One of the first functioning steamships , Palmipède , which was also the first paddle steamer, was built in France in 1774 by Marquis Claude de Jouffroy and his colleagues. The 13 m (42 ft 8 in) steamer with rotating paddles sailed on the Doubs River in June and July 1776. In 1783,

784-430: A few further experiments until SS  Aberdeen  (1881) went into service on the route from Britain to Australia. Her triple expansion engine was designed by Dr A C Kirk, the engineer who had developed the machinery for Propontis . The difference was the use of two double ended Scotch type steel boilers, running at 125 pounds per square inch (860 kPa). These boilers had patent corrugated furnaces that overcame

896-551: A few years, new installations were running at 200 pounds per square inch (1,400 kPa). The tramp steamers that operated at the end of the 1880s could sail at 9 knots (17 km/h; 10 mph) with a fuel consumption of 0.5 ounces (14 g) of coal per ton mile travelled. This level of efficiency meant that steamships could now operate as the primary method of maritime transport in the vast majority of commercial situations. In 1890, steamers constituted 57% of world's tonnage, and by World War I their share raised to 93%. By 1870

1008-453: A full rig of sail for when winds were favorable, being unable to complete the voyage under power alone. In 1822, Charles Napier 's Aaron Manby , the world's first iron ship, made the first direct steam crossing from London to Paris and the first seagoing voyage by an iron ship. In 1838, Sirius , a fairly small steam packet built for the Cork to London route, became the first vessel to cross

1120-473: A given distance, but fewer firemen were needed to fuel the boilers, so crew costs and their accommodation space were reduced. Agamemnon was able to sail from London to China with a coaling stop at Mauritius on the outward and return journey, with a time on passage substantially less than the competing sailing vessels. Holt had already ordered two sister ships to Agamemnon by the time she had returned from her first trip to China in 1866, operating these ships in

1232-504: A head wind, most notably against the southwest monsoon when returning with a cargo of new tea. Though the auxiliary steamers persisted in competing in far eastern trade for a few years (and it was Erl King that carried the first cargo of tea through the Suez Canal ), they soon moved on to other routes. What was needed was a big improvement in fuel efficiency. While the boilers for steam engines on land were allowed to run at high pressures,

1344-403: A long bush of soft metal was fitted in the after end of the stern tube. SS  Great Eastern had this arrangement fail on her first transatlantic voyage, with very large amounts of uneven wear. The problem was solved with a lignum vitae water-lubricated bearing, patented in 1858. This became standard practice and is in use today. Since the motive power of screw propulsion is delivered along

1456-448: A means of propulsion comes from the fourth– or fifth-century military treatise De Rebus Bellicis (chapter XVII), where the anonymous Roman author describes an ox-driven paddle-wheel warship: Animal power, directed by the resources on ingenuity, drives with ease and swiftness, wherever utility summons it, a warship suitable for naval combats, which, because of its enormous size, human frailty as it were prevented from being operated by

1568-551: A new paddle steamer by de Jouffroy, Pyroscaphe , successfully steamed up the river Saône for 15 minutes before the engine failed. Bureaucracy and the French Revolution thwarted further progress by de Jouffroy. The next successful attempt at a paddle-driven steam ship was by Scottish engineer William Symington , who suggested steam power to Patrick Miller of Dalswinton . Experimental boats built in 1788 and 1789 worked successfully on Lochmaben Loch. In 1802, Symington built

1680-495: A number of inventions such as the screw propeller , the compound engine , and the triple-expansion engine made trans-oceanic shipping on a large scale economically viable. In 1870 the White Star Line ’s RMS  Oceanic set a new standard for ocean travel by having its first-class cabins amidships, with the added amenity of large portholes, electricity and running water. The size of ocean liners increased from 1880 to meet

1792-472: A number still operate. European sidewheelers, such as PS  Waverley , connect the wheels with solid drive shafts that limit maneuverability and give the craft a wide turning radius. Some were built with paddle clutches that disengage one or both paddles so they can turn independently. However, wisdom gained from early experience with sidewheelers deemed that they be operated with clutches out, or as solid-shaft vessels. Crews noticed that as ships approached

1904-477: A paddle wheel is normally enclosed in a paddlebox to minimise splashing. The three types of paddle wheel steamer are sidewheeler, with one paddlewheel amidships on each side; sternwheeler, with a single paddlewheel at the stern ; and (rarely) inboard, with the paddlewheel mounted in a recess amidships. The earliest steam vessel s were sidewheelers, and the type was by far the dominant mode of marine steam propulsion, both for steamships and steamboats, until

2016-665: A paddle-wheel ship from China is in the History of the Southern Dynasties , compiled in the 7th century but describing the naval ships of the Liu Song dynasty (420–479) used by admiral Wang Zhen'e in his campaign against the Qiang in 418 AD. The ancient Chinese mathematician and astronomer Zu Chongzhi (429–500) had a paddle-wheel ship built on the Xinting River (south of Nanjing ) known as

2128-458: A particularly compact compound engine and taken great care with the hull design, producing a light, strong, easily driven hull. The efficiency of Holt's package of boiler pressure, compound engine and hull design gave a ship that could steam at 10 knots on 20 long tons of coal a day. This fuel consumption was a saving from between 23 and 14 long tons a day, compared to other contemporary steamers. Not only did less coal need to be carried to travel

2240-470: A reduction gear, rotate directly the propellers), or turboelectric (the turbines rotate electric generators, which in turn feed electric motors operating the propellers). While steam turbine-driven merchant ships such as the Algol -class cargo ships (1972–1973), ALP Pacesetter-class container ships (1973–1974) and very large crude carriers were built until the 1970s, the use of steam for marine propulsion in

2352-462: A rod and lever. The geometry is designed such that the paddles are kept almost vertical for the short duration that they are in the water. The use of a paddle wheel in navigation appears for the first time in the mechanical treatise of the Roman engineer Vitruvius ( De architectura , X 9.5–7), where he describes multigeared paddle wheels working as a ship odometer . The first mention of paddle wheels as

2464-426: A sailing vessel. The steam engine would only be used when conditions were unsuitable for sailing – in light or contrary winds. Some of this type (for instance Erl King ) were built with propellers that could be lifted clear of the water to reduce drag when under sail power alone. These ships struggled to be successful on the route to China, as the standing rigging required when sailing was a handicap when steaming into

2576-675: A scientific expedition to New Guinea. Mr. Witkiewicz soon abandoned the expedition and returned to Europe, to sign up for military service during the First World War. After the First World War began, Orontes remained in service on her regular route until October 1916, when the Admiralty requisitioned her. She was converted into the Royal Navy troop ship HMAT Orontes . HMAT stands for "His Majesty's Australian Transport". She made two more voyages from Britain to Australia, before spending some time on

2688-399: A shaft that is positioned above the waterline, with the cylinders positioned below the shaft. SS  Great Britain used chain drive to transmit power from a paddler's engine to the propeller shaft – the result of a late design change to propeller propulsion. An effective stern tube and associated bearings were required. The stern tube contains the propeller shaft where it passes through

2800-494: A side,". The standard Chinese term "wheel ship" was used by the Song period, whereas a litany of colorful terms were used to describe it beforehand. In the 12th century, the Song government used paddle-wheel ships en masse to defeat opposing armies of pirates armed with their own paddle-wheel ships. At the Battle of Caishi in 1161, paddle-wheelers were also used with great success against

2912-419: A simple paddle wheel, where the paddles are fixed around the periphery, power is lost due to churning of the water as the paddles enter and leave the water surface. Ideally, the paddles should remain vertical while under water. This ideal can be approximated by use of levers and linkages connected to a fixed eccentric. The eccentric is fixed slightly forward of the main wheel centre. It is coupled to each paddle by

3024-541: A steam-powered desalinator created by Garay for a steam boiler. In 1705, Papin constructed a ship powered by hand-cranked paddles. An apocryphal story originating in 1851 by Louis Figuire held that this ship was steam-powered rather than hand-powered and that it was therefore the first steam-powered vehicle of any kind. The myth was refuted as early as 1880 by Ernst Gerland  [ de ] , though still it finds credulous expression in some contemporary scholarly work. In 1787, Patrick Miller of Dalswinton invented

3136-422: Is a steamship or steamboat powered by a steam engine driving paddle wheels to propel the craft through the water. In antiquity, paddle wheelers followed the development of poles, oars and sails, whereby the first uses were wheelers driven by animals or humans. In the early 19th century, paddle wheels were the predominant way of propulsion for steam-powered boats. In the late 19th century, paddle propulsion

3248-416: Is fitted with numerous, regularly spaced paddle blades (called floats or buckets). The bottom quarter or so of the wheel travels under water. An engine rotates the paddle wheel in the water to produce thrust , forward or backward as required. More advanced paddle-wheel designs feature "feathering" methods that keep each paddle blade closer to vertical while in the water to increase efficiency. The upper part of

3360-515: The Board of Trade (under the authority of the Merchant Shipping Act 1854 ) would not allow ships to exceed 20 or 25 pounds per square inch (140 or 170 kPa). Compound engines were a known source of improved efficiency – but generally not used at sea due to the low pressures available. Carnatic (1863) , a P&O ship, had a compound engine – and achieved better efficiency than other ships of

3472-453: The Cold War (eg. Russian aircraft carrier Admiral Kuznetsov ), because of needs of high power and speed, although from 1970s they were mostly replaced by gas turbines . Large naval vessels and submarines continue to be operated with steam turbines, using nuclear reactors to boil the water. NS Savannah , was the first nuclear-powered cargo-passenger ship, and was built in the late 1950s as

3584-630: The Crimean War of 1853–1856, and by the United States Navy during the Mexican War of 1846–1848 and the American Civil War of 1861–1865. With the arrival of ironclad battleships from the late 1850s, the last remaining paddle frigates were decommissioned and sold into merchant-navy service by the 1870s. These included Miami , which became one of the first Boston steamers in 1867. At

3696-478: The Dunkirk Evacuation in 1940, where they were able to get close inshore to embark directly from the beach. One example was PS  Medway Queen , which saved an estimated 7,000 men over the nine days of the evacuation, and claimed to have shot down three German aircraft. Another paddle minesweeper, HMS  Oriole , was deliberately beached twice to allow soldiers to cross to other vessels using her as

3808-677: The East Coast to the West Coast of the United States began on 28 February 1849, with the arrival of SS  California in San Francisco Bay . The California left New York Harbor on 6  October 1848, rounded Cape Horn at the tip of South America, and arrived at San Francisco, California, after a four-month and 21-day journey. The first steamship to operate on the Pacific Ocean was

3920-819: The Jin dynasty (1115–1234) navy. The Chinese used the paddle-wheel ship even during the First Opium War (1839–1842) and for transport around the Pearl River during the early 20th century. Paddle steamers in Bangladesh were first operated by the River Steam Navigation Company Limited in 1878. Many steamers, including the Garrow , Florikan , Burma , Majabi , Flamingo , Kiyi , Mohamend , Sherpa , Pathan , Sandra , Irani , Seal , Lali , and Mekla , dominated

4032-573: The Mediterranean and then through the Red Sea . While this worked for passengers and some high value cargo, sail was still the only solution for virtually all trade between China and Western Europe or East Coast America. Most notable of these cargoes was tea , typically carried in clippers . Another partial solution was the Steam Auxiliary Ship – a vessel with a steam engine, but also rigged as

4144-686: The Racecourse-class minesweepers , were ordered and 32 of them were built before the end of the war. In the Second World War , some thirty pleasure paddle steamers were again requisitioned; an added advantage was that their wooden hulls did not activate the new magnetic mines. The paddle ships formed six minesweeping flotillas , based at ports around the British coast. Other paddle steamers were converted to anti-aircraft ships. More than twenty paddle steamers were used as emergency troop transports during

4256-662: The River Clyde in 1812. In 1812, the first U.S. Mississippi River paddle steamer began operating out of New Orleans. By 1814, Captain Henry Shreve had developed a "steamboat" suitable for local conditions. Landings in New Orleans went from 21 in 1814 to 191 in 1819, and over 1,200 in 1833. The first stern-wheeler was designed by Gerhard Moritz Roentgen from Rotterdam, and used between Antwerp and Ghent in 1827. Team boats , paddle boats driven by horses, were used for ferries

4368-563: The Thames steamers which took passengers from London to Southend-on-Sea and Margate , Clyde steamers that connected Glasgow with the resort of Rothsay and the Köln-Düsseldorfer cruise steamers on the River Rhine . Paddle steamer services continued into the mid-20th century, when ownership of motor cars finally made them obsolete except for a few heritage examples. The first mention of

4480-696: The reciprocating steam engine , and was far easier to control. Diesel engines also required far less supervision and maintenance than steam engines, and as an internal combustion engine it did not need boilers or a water supply, therefore was more space efficient and cheaper to build. The Liberty ships were the last major steamship class equipped with reciprocating engines. The last Victory ships had already been equipped with marine diesels, and diesel engines superseded both steamers and windjammers soon after World War Two. Most steamers were used up to their maximum economical life span, and no commercial ocean-going steamers with reciprocating engines have been built since

4592-498: The " thousand league boat ". When campaigning against Hou Jing in 552, the Liang dynasty (502–557) admiral Xu Shipu employed paddle-wheel boats called "water-wheel boats". At the siege of Liyang in 573, the admiral Huang Faqiu employed foot-treadle powered paddle-wheel boats. A successful paddle-wheel warship design was made in China by Prince Li Gao in 784 AD, during an imperial examination of

4704-746: The 116-ton Aaron Manby , built in 1821 by Aaron Manby at the Horseley Ironworks , and became the first iron-built vessel to put to sea when she crossed the English Channel in 1822, arriving in Paris on 22 June. She carried passengers and freight to Paris in 1822 at an average speed of 8 knots (9 mph, 14 km/h). The American ship SS  Savannah first crossed the Atlantic Ocean arriving in Liverpool, England, on June 20, 1819, although most of

4816-423: The 1820s, paddle steamers were used to take tourists from the rapidly expanding industrial cities on river cruises, or to the newly established seaside resorts , where pleasure piers were built to allow passengers to disembark regardless of the state of the tide. Later, these paddle steamers were fitted with luxurious saloons in an effort to compete with the facilities available on the railways. Notable examples are

4928-401: The 1960s. Most steamships today are powered by steam turbines . After the demonstration by British engineer Charles Parsons of his steam turbine-driven yacht, Turbinia , in 1897, the use of steam turbines for propulsion quickly spread. The Cunard RMS Mauretania , built in 1906 was one of the first ocean liners to use the steam turbine (with a late design change shortly before her keel

5040-614: The 1980s, the steam engines were replaced with diesel ones, and the wooden paddles were replaced with iron ones. Hydraulic steering was introduced in the 1990s, followed by electro-hydraulic systems in 2020. Modern equipment such as radar and GPS was also installed. However, PS Gazi , PS Teal , and PS Kiwi were decommissioned in the late '90s after catching fire while docked for repairs. Until 2022, four paddle steamers—PS Ostrich (built in Scotland in 1929), PS Mahsud (1928), PS Lepcha (1938), and PS Tern (1950)—were operated by

5152-617: The Africa run. In 1917, the Admiralty released her to her owners, as her refrigerated hold made her more useful for taking dairy products and meat from Australia to Britain. In 1919 Orontes resumed her Australia service with calls at Gibraltar , Toulon , Port Said , Colombo , Fremantle , Adelaide , Melbourne, Sydney and an extension to Brisbane . In 1921 Orontes was laid up in the Thames. In 1922 British World Trade Expeditions Ltd bought her with

5264-470: The Atlantic Ocean on a scheduled liner voyage before she was converted to diesels in 1986. The last major passenger ship built with steam turbines was the Fairsky , launched in 1984, later Atlantic Star , reportedly sold to Turkish shipbreakers in 2013. Most luxury yachts at the end of the 19th and early 20th centuries were steam driven (see luxury yacht ; also Cox & King yachts ). Thomas Assheton Smith

5376-462: The Atlantic under sustained steam power, beating Isambard Kingdom Brunel 's much larger Great Western by a day. Great Western , however, was actually built for the transatlantic trade, and so had sufficient coal for the passage; Sirius had to burn furniture and other items after running out of coal. Great Western ' s more successful crossing began the regular sailing of powered vessels across

5488-528: The Atlantic, around the southern tip of Africa, and across the Indian Ocean . Before 1866, no steamship could carry enough coal to make this voyage and have enough space left to carry a commercial cargo. A partial solution to this problem was adopted by the Peninsular and Oriental Steam Navigation Company (P&O), using an overland section between Alexandria and Suez , with connecting steamship routes along

5600-629: The Atlantic. Beaver was the first coastal steamship to operate in the Pacific Northwest of North America. Paddle steamers helped open Japan to the Western World in the mid-19th century. The largest paddle-steamer ever built was Brunel's Great Eastern , but it also had screw propulsion and sail rigging. It was 692 ft (211 m) long and weighed 32,000 tons, its paddlewheels being 56 ft (17 m) in diameter. In oceangoing service, paddle steamers became much less useful after

5712-670: The BIWTC once a week. This was a reduction from daily trips, and commercial services were eventually stopped altogether due to safety concerns, operational losses, and a lack of passengers, especially following the inauguration of the Padma Bridge . The first seagoing trip of a paddle steamer was by the Albany in 1808. It steamed from the Hudson River along the coast to the Delaware River . This

5824-463: The Bristol-New York route. The idea of regular scheduled transatlantic service was under discussion by several groups and the rival British and American Steam Navigation Company was established at the same time. Great Western's design sparked controversy from critics that contended that she was too big. The principle that Brunel understood was that the carrying capacity of a hull increases as

5936-465: The Liverpool to New York route. RMS  Titanic was the largest steamship in the world when she sank in 1912; a subsequent major sinking of a steamer was that of the RMS ; Lusitania , as an act of World War I . Launched in 1938, RMS  Queen Elizabeth was the largest passenger steamship ever built. Launched in 1969, Queen Elizabeth 2 (QE2) was the last passenger steamship to cross

6048-504: The Mississippi . Recessed or inboard paddlewheel boats were designed to ply narrow and snag-infested backwaters. By recessing the wheel within the hull it was protected somewhat from damage. It was enclosed and could be spun at a high speed to provide acute maneuverability. Most were built with inclined steam cylinders mounted on both sides of the paddleshaft and timed 90 degrees apart like a locomotive, making them instantly reversing. In

6160-475: The Seine, between Paris and Le Havre. The first paddle-steamer to make a long ocean voyage crossing the Atlantic Ocean was SS  Savannah , built in 1819 expressly for this service. Savannah set out for Liverpool on May 22, 1819, sighting Ireland after 23 days at sea. This was the first powered crossing of the Atlantic, although Savannah was built as a sailing ship with a steam auxiliary; she also carried

6272-553: The United States from the 1820s–1850s, as they were economical and did not incur licensing costs imposed by the steam navigation monopoly. In the 1850s, they were replaced by steamboats. After the American Civil War, as the expanding railroads took many passengers, the traffic became primarily bulk cargoes. The largest, and one of the last, paddle steamers on the Mississippi was the sternwheeler Sprague . Built in 1901, she pushed coal and petroleum until 1948. In Europe from

6384-531: The Woodside Hotel, Aberdour. It includes a stained glass ceiling and expertly turned ornamental woodwork. This remnant of the ship still survives, and the hotel is now a Category B listed building . Steamship As steamships were less dependent on wind patterns, new trade routes opened up. The steamship has been described as a "major driver of the first wave of trade globalization (1870–1913)" and contributor to "an increase in international trade that

6496-426: The commercial market has declined dramatically due to the development of more efficient diesel engines . One notable exception are LNG carriers which use boil-off gas from the cargo tanks as fuel. However, even there the development of dual-fuel engines has pushed steam turbines into a niche market with about 10% market share in newbuildings in 2013. Lately, there has been some development in hybrid power plants where

6608-436: The competing problems of heat transfer and sufficient strength to deal with the boiler pressure. Aberdeen was a marked success, achieving in trials, at 1,800 indicated horsepower , a fuel consumption of 1.28 pounds (0.58 kg) of coal per indicated horsepower. This was a reduction in fuel consumption of about 60%, compared to a typical steamer built ten years earlier. In service, this translated into less than 40 tons of coal

6720-435: The cube of its dimensions, while water resistance only increases as the square of its dimensions. This meant that large ships were more fuel efficient, something very important for long voyages across the Atlantic. Great Western was an iron-strapped, wooden, side-wheel paddle steamer, with four masts to hoist the auxiliary sails. The sails were not just to provide auxiliary propulsion, but also were used in rough seas to keep

6832-472: The development of the propeller – which was more efficient and less vulnerable to cannon fire. One of the first screw-driven warships, HMS  Rattler  (1843) , demonstrated her superiority over paddle steamers during numerous trials, including one in 1845 where she pulled a paddle-driven sister ship backwards in a tug of war . However, paddle warships were used extensively by the Russian Navy during

6944-401: The dock, passengers moved to the side of the ship ready to disembark. The shift in weight, added to independent movements of the paddles, could lead to imbalance and potential capsizing . Paddle tugs were frequently operated with clutches in, as the lack of passengers aboard meant that independent paddle movement could be used safely and the added maneuverability exploited to the full. Although

This was superseded at the beginning of the 20th century by floating pad bearing which automatically built up wedges of oil which could withstand bearing pressures of 500 psi or more. Steam-powered ships were named with a prefix designating their propeller configuration i.e. single, twin, triple-screw. Single-screw Steamship SS , Twin-Screw Steamship TSS , Triple-Screw Steamship TrSS . Steam turbine-driven ships had

The development of screw propulsion relied on the following technological innovations. Steam engines had to be designed with the power delivered at the bottom of the machinery, to give direct drive to the propeller shaft . A paddle steamer's engines drive

7280-677: The first sternwheelers were invented in Europe, they saw the most service in North America, especially on the Mississippi River. Enterprise was built at Brownsville, Pennsylvania , in 1814 as an improvement over the less efficient side-wheelers. The second stern-wheeler built, Washington of 1816, had two decks and served as the prototype for all subsequent steamboats of the Mississippi , including those made famous in Mark Twain 's book Life on

7392-427: The hands of men. In its hull, or hollow interior, oxen, yoked in pairs to capstans, turn wheels attached to the sides of the ship; paddles, projecting above the circumference or curved surface of the wheels, beating the water with their strokes like oar-blades as the wheels revolve, work with an amazing and ingenious effect, their action producing rapid motion. This warship, moreover, because of its own bulk and because of

7504-425: The hull as waves pass beneath it—becomes too great. Iron hulls are far less subject to hogging, so that the potential size of an iron-hulled ship is much greater. In the spring of 1840 Brunel also had the opportunity to inspect SS  Archimedes , the first screw-propelled steamship, completed only a few months before by F. P. Smith's Propeller Steamship Company. Brunel had been looking into methods of improving

7616-429: The hull structure. It should provide an unrestricted delivery of power by the propeller shaft. The combination of hull and stern tube must avoid any flexing that will bend the shaft or cause uneven wear. The inboard end has a stuffing box that prevents water from entering the hull along the tube. Some early stern tubes were made of brass and operated as a water lubricated bearing along the entire length. In other instances

7728-519: The increasing adoption of screw propulsion from the 1850s. Though the side wheels and enclosing sponsons make them wider than sternwheelers, they may be more maneuverable, since they can sometimes move the paddles at different speeds, and even in opposite directions. This extra maneuverability makes side-wheelers popular on the narrower, winding rivers of the Murray–Darling system in Australia, where

7840-400: The intent of converting her to an exhibition vessel. She was to be renamed British Trade , but it is not clear whether her change of name was ever registered. Orient Line repossessed the ship. In 1925 Orontes was sold for scrap to Thos. W. Ward . She arrived at Inverkeithing on 22 October that year to be broken up. The upper part of Orontes smoking room was salvaged and installed in

7952-417: The invention of the screw propeller, but they remained in use in coastal service and as river tugboats , thanks to their shallow draught and good maneuverability. The last crossing of the Atlantic by paddle steamer began on September 18, 1969, the first leg of a journey to conclude six months and nine days later. The steam paddle tug Eppleton Hall was never intended for oceangoing service, but nevertheless

8064-521: The machinery working inside it, joins battle with such pounding force that it easily wrecks and destroys all enemy warships coming at close quarters. Italian physician Guido da Vigevano ( circa 1280–1349), planning for a new crusade, made illustrations for a paddle boat that was propelled by manually turned compound cranks . One of the drawings of the Anonymous Author of the Hussite Wars shows

8176-494: The most famous being the modified Portuguese carrack La Trinidad , which surpassed a nearby galley in speed and maneuverability on June 17, 1543, in the harbor of Barcelona . The project, however, was discontinued. 19th century writer Tomás González claimed to have found proof that at least some of these vessels were steam-powered, but this theory was discredited by the Spanish authorities. It has been proposed that González mistook

8288-402: The needs of the human migration to the United States and Australia. RMS  Umbria and her sister ship RMS  Etruria were the last two Cunard liners of the period to be fitted with auxiliary sails. Both ships were built by John Elder & Co. of Glasgow, Scotland, in 1884. They were record breakers by the standards of the time, and were the largest liners then in service, plying

8400-525: The newly formed Blue Funnel Line . His competitors rapidly copied his ideas for their own new ships. The opening of the Suez Canal in 1869 gave a distance saving of about 3,250 nautical miles (6,020 km; 3,740 mi) on the route from China to London. The canal was not a practical option for sailing vessels, as using a tug was difficult and expensive – so this distance saving was not available to them. Steamships immediately made use of this new waterway and found themselves in high demand in China for

8512-419: The operating costs of steamships were still too high in certain trades, so sail was the only commercial option in many situations. The compound engine, where steam was expanded twice in two separate cylinders, still had inefficiencies. The solution was the triple expansion engine, in which steam was successively expanded in a high pressure, intermediate pressure and a low pressure cylinder. The theory of this

8624-451: The paddle steamer Beaver , launched in 1836 to service Hudson's Bay Company trading posts between Puget Sound Washington and Alaska . The most testing route for steam was from Britain or the East Coast of the U.S. to the Far East . The distance from either is roughly the same, between 14,000 to 15,000 nautical miles (26,000 to 28,000 km; 16,000 to 17,000 mi), traveling down

8736-504: The paddle wheel causing a substantial decrease in performance. Within a few decades of the development of the river and canal steamboat, the first steamships began to cross the Atlantic Ocean . The first sea-going steamboat was Richard Wright's first steamboat Experiment , an ex-French lugger ; she steamed from Leeds to Yarmouth in July 1813. The first iron steamship to go to sea was

8848-453: The performance of Great Britain ' s paddlewheels, and took an immediate interest in the new technology, and Smith, sensing a prestigious new customer for his own company, agreed to lend Archimedes to Brunel for extended tests. Over several months, Smith and Brunel tested a number of different propellers on Archimedes in order to find the most efficient design, a four-bladed model submitted by Smith. When launched in 1843, Great Britain

8960-773: The port of Savannah, Georgia , US, on 22 May 1819, arriving in Liverpool , England, on 20 June 1819; her steam engine having been in use for part of the time on 18 days (estimates vary from 8 to 80 hours). A claimant to the title of the first ship to make the transatlantic trip substantially under steam power is the British-built Dutch-owned Curaçao , a wooden 438-ton vessel built in Dover and powered by two 50 hp engines, which crossed from Hellevoetsluis , near Rotterdam on 26 April 1827 to Paramaribo , Surinam on 24 May, spending 11 days under steam on

9072-504: The prefix TS . In the UK the prefix RMS for Royal Mail Steamship overruled the screw configuration prefix. The first steamship credited with crossing the Atlantic Ocean between North America and Europe was the American ship SS  Savannah , though she was actually a hybrid between a steamship and a sailing ship, with the first half of the journey making use of the steam engine. Savannah left

9184-486: The provinces by the Tang dynasty (618–907) emperor. The Chinese Song dynasty (960–1279) issued the construction of many paddle-wheel ships for its standing navy , and according to the British biochemist, historian, and sinologist Joseph Needham : "...between 1132 and 1183 (AD) a great number of treadmill-operated paddle-wheel craft, large and small, were built, including sternwheelers and ships with as many as 11 paddle-wheels

9296-526: The revolutionary SS  Great Britain , also built by Brunel, became the first iron-hulled screw-driven ship to cross the Atlantic. SS Great Britain was the first ship to combine these two innovations. After the initial success of its first liner, SS  Great Western of 1838, the Great Western Steamship Company assembled the same engineering team that had collaborated so successfully before. This time however, Brunel, whose reputation

9408-478: The shaft, a thrust bearing is needed to transfer that load to the hull without excessive friction. SS  Great Britain had a 2 ft diameter gunmetal plate on the forward end of the shaft which bore against a steel plate attached to the engine beds. Water at 200 psi was injected between these two surfaces to lubricate and separate them. This arrangement was not sufficient for higher engine powers and oil lubricated "collar" thrust bearings became standard from

9520-477: The ship on an even keel and ensure that both paddle wheels remained in the water, driving the ship in a straight line. The hull was built of oak by traditional methods. She was the largest steamship for one year, until the British and American's British Queen went into service. Built at the shipyard of Patterson & Mercer in Bristol, Great Western was launched on 19 July 1837 and then sailed to London, where she

9632-721: The southern rivers. In 1958, Pakistan River Steamers inherited the fleet, some of which were built at the private Garden Rich Dockyard in Kolkata . After the liberation of Bangladesh , there were around 13 paddle steamers in 1972, nicknamed “the Rockets” for their speed, operated by the newly founded Bangladesh Inland Water Transport Corporation (BIWTC). These included PS Sandra , PS Lali , PS Mohammed , PS Gazi , PS Kiwi , PS Ostrich , PS Mahsud , PS Lepcha , and PS Tern . The steamers served destinations such as Chandpur , Barisal , Khulna , Morrelganj , and Kolkata , from Dhaka . In

9744-465: The start of the First World War , the Royal Navy requisitioned more than fifty pleasure paddle steamers for use as auxiliary minesweepers . The large spaces on their decks intended for promenading passengers proved to be ideal for handling the minesweeping booms and cables, and the paddles allowed them to operate in coastal shallows and estuaries. These were so successful that a new class of paddle ships,

9856-511: The start of the 1870 tea season. The steamships were able to obtain a much higher rate of freight than sailing ships and the insurance premium for the cargo was less. So successful were the steamers using the Suez Canal that, in 1871, 45 were built in Clyde shipyards alone for Far Eastern trade. Throughout the 1870s, compound-engined steamships and sailing vessels coexisted in an economic equilibrium:

9968-580: The steam turbine is used together with gas engines. As of August 2017 the newest class of Steam Turbine ships are the Seri Camellia -class LNG carriers built by Hyundai Heavy Industries (HHI) starting in 2016 and comprising five units. Nuclear powered ships are basically steam turbine vessels. The boiler is heated, not by heat of combustion , but by the heat generated by nuclear reactor. Most atomic-powered ships today are either aircraft carriers or submarines . Paddle steamer A paddle steamer

10080-414: The technology changed the design of ships for faster, more economic propulsion. Paddlewheels as the main motive source became standard on these early vessels. It was an effective means of propulsion under ideal conditions but otherwise had serious drawbacks. The paddle-wheel performed best when it operated at a certain depth, however when the depth of the ship changed from added weight it further submerged

10192-603: The time. Her boilers ran at 26 pounds per square inch (180 kPa) but relied on a substantial amount of superheat . Alfred Holt , who had entered marine engineering and ship management after an apprenticeship in railway engineering, experimented with boiler pressures of 60 pounds per square inch (410 kPa) in Cleator . Holt was able to persuade the Board of Trade to allow these boiler pressures and, in partnership with his brother Phillip launched Agamemnon in 1865. Holt had designed

10304-404: The voyage was actually made under sail. The first ship to make the transatlantic trip substantially under steam power may have been the British-built Dutch-owned Curaçao , a wooden 438-ton vessel built in Dover and powered by two 50 hp engines, which crossed from Hellevoetsluis , near Rotterdam on 26 April 1827 to Paramaribo , Surinam on 24 May, spending 11 days under steam on

10416-474: The way out and more on the return. Another claimant is the Canadian ship SS  Royal William in 1833. The British side-wheel paddle steamer SS  Great Western was the first steamship purpose-built for regularly scheduled trans-Atlantic crossings, starting in 1838. In 1836 Isambard Kingdom Brunel and a group of Bristol investors formed the Great Western Steamship Company to build a line of steamships for

10528-499: The way out and more on the return. Another claimant is the Canadian ship SS  Royal William in 1833. The first steamship purpose-built for regularly scheduled trans-Atlantic crossings was the British side-wheel paddle steamer SS  Great Western built by Isambard Kingdom Brunel in 1838, which inaugurated the era of the trans-Atlantic ocean liner . SS  Archimedes , built in Britain in 1839 by Francis Pettit Smith ,

10640-645: Was 115707 and her code letters were TPWN. Orontes began her maiden voyage on 24 October 1902, taking mail and passengers from London via the Suez Canal and Melbourne to Sydney . This was her regular route. By 1913 Orontes was equipped for wireless telegraphy , operating on the 300 and 600 metre wavelengths. Her call sign was MOZ. In 1914, between the 11th and the 21st of July, two Polish passengers, Mr. B. Malinowski, anthropologist, and Mr. St. I. Witkiewicz, artist, travel in RMS Orontes from Colombo, Ceylon, to Fremantle, Australia. Mr. Witkiewicz takes part in

10752-554: Was an English aristocrat who forwarded the design of the steam yacht in conjunction with the Scottish marine engineer Robert Napier . By World War II , steamers still constituted 73% of world's tonnage, and similar percentage remained in early 1950s. The decline of the steamship began soon thereafter. Many had been lost in the war, and marine diesel engines had finally matured as an economical and viable alternative to steam power. The diesel engine had far better thermal efficiency than

10864-466: Was at its height, came to assert overall control over design of the ship—a state of affairs that would have far-reaching consequences for the company. Construction was carried out in a specially adapted dry dock in Bristol , England. Brunel was given a chance to inspect John Laird 's 213-foot (65 m) (English) channel packet ship Rainbow —the largest iron- hulled ship then in service—in 1838, and

10976-479: Was by far the largest vessel afloat. Brunel's last major project, SS  Great Eastern , was built in 1854–1857 with the intent of linking Great Britain with India, via the Cape of Good Hope , without any coaling stops. This ship was arguably more revolutionary than her predecessors. She was one of the first ships to be built with a double hull with watertight compartments and was the first liner to have four funnels. She

11088-402: Was established in the 1850s by John Elder , but it was clear that triple expansion engines needed steam at, by the standards of the day, very high pressures. The existing boiler technology could not deliver this. Wrought iron could not provide the strength for the higher pressures. Steel became available in larger quantities in the 1870s, but the quality was variable. The overall design of boilers

11200-452: Was fitted with two side-lever steam engines from the firm of Maudslay, Sons & Field , producing 750 indicated horsepower between them. The ship proved satisfactory in service and initiated the transatlantic route, acting as a model for all following Atlantic paddle-steamers. The Cunard Line 's RMS  Britannia began her first regular passenger and cargo service by a steamship in 1840, sailing from Liverpool to Boston. In 1845

11312-557: Was improved in the early 1860s, with the Scotch-type boilers – but at that date these still ran at the lower pressures that were then current. The first ship fitted with triple expansion engines was Propontis (launched in 1874). She was fitted with boilers that operated at 150 pounds per square inch (1,000 kPa) – but these had technical problems and had to be replaced with ones that ran at 90 pounds per square inch (620 kPa). This substantially degraded performance. There were

11424-405: Was laid down) and was soon followed by all subsequent liners. Most larger warships of the world's navies were propelled by steam turbines burning bunker fuel in both World Wars, apart from obsolete ships with reciprocating machines from the turn of the century, and rare cases of usage of diesel engines in larger warships. Steam turbines burning fuel remained in warship construction until the end of

11536-400: Was largely superseded by the screw propeller and other marine propulsion systems that have a higher efficiency, especially in rough or open water. Paddle wheels continue to be used by small, pedal-powered paddle boats and by some ships that operate tourist voyages. The latter are often powered by diesel engines. The paddle wheel is a large steel framework wheel. The outer edge of the wheel

11648-465: Was purely for the purpose of moving a river-boat to a new market, but paddle-steamers began regular short coastal trips soon after. In 1816 Pierre Andriel, a French businessman, bought in London the 15  hp (11 kW) paddle steamer Margery (later renamed Elise ) and made an eventful London- Le Havre -Paris crossing, encountering heavy weather on the way. He later operated his ship as a river packet on

11760-416: Was soon converted to iron-hulled technology. He scrapped his plans to build a wooden ship and persuaded the company directors to build an iron-hulled ship. Iron's advantages included being much cheaper than wood, not being subject to dry rot or woodworm , and its much greater structural strength. The practical limit on the length of a wooden-hulled ship is about 300 feet, after which hogging —the flexing of

11872-636: Was steamed from Newcastle to San Francisco. As the voyage was intended to be completed under power, the tug was rigged as steam propelled with a sail auxiliary. The transatlantic stage of the voyage was completed exactly 150 years after the voyage of Savannah . As of 2022, the PS Waverley is the last seagoing passenger-carrying paddle steamer in the world. Beginning in the 1820s, the British Royal Navy began building paddle-driven steam frigates and steam sloops . By 1850 these had become obsolete due to

11984-420: Was the 19,970  GRT turbine steamship SS Orontes that was launched in 1929 and scrapped in 1962. The Fairfield Shipbuilding and Engineering Company of Govan launched Orontes on 10 May 1902 and completed her that September. At 9,028  GRT she was Orient Line's largest ship until Orsova and her sisters entered service in 1909. Orient Line registered her at Glasgow. Her UK official number

12096-456: Was the biggest liner throughout the rest of the 19th century with a gross tonnage of almost 20,000 tons and had a passenger-carrying capacity of thousands. The ship was ahead of her time and went through a turbulent history, never being put to her intended use. The first transatlantic steamer built of steel was SS  Buenos Ayrean , built by Allan Line Royal Mail Steamers and entering service in 1879. The first regular steamship service from

12208-399: Was the change from the paddle-wheel to the screw-propeller as the mechanism of propulsion. These steamships quickly became more popular, because the propeller's efficiency was consistent regardless of the depth at which it operated. Being smaller in size and mass and being completely submerged, it was also far less prone to damage. James Watt of Scotland is widely given credit for applying

12320-458: Was the first commercial paddle steamer and steamboat , the first commercial success was possibly Robert Fulton 's Clermont in New York, which went into commercial service in 1807 between New York City and Albany . Many other paddle-equipped river boats followed all around the world; the first in Europe being PS  Comet designed by Henry Bell which started a scheduled passenger service on

12432-514: Was the world's first screw propeller -driven steamship for open water seagoing. She had considerable influence on ship development, encouraging the adoption of screw propulsion by the Royal Navy , in addition to her influence on commercial vessels. The first screw-driven propeller steamship introduced in America was on a ship built by Thomas Clyde in 1844 and many more ships and routes followed. The key innovation that made ocean-going steamers viable

12544-491: Was unprecedented in human history". Steamships were preceded by smaller vessels, called steamboats , conceived in the first half of the 18th century, with the first working steamboat and paddle steamer , the Pyroscaphe , from 1783. Once the technology of steam was mastered at this level, steam engines were mounted on larger, and eventually, ocean-going vessels. Becoming reliable, and propelled by screw rather than paddlewheels,
