77-499: SS Winfield Scott was a sidewheel steamer that transported passengers and cargo between San Francisco, California and Panama in the early 1850s, during the California Gold Rush . After entering a heavy fog off the coast of Southern California on the evening of December 1, 1853, the ship crashed into Middle Anacapa Island . All 450 passengers and crew survived, but the ship was lost. Winfield Scott has been

154-462: 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

231-622: A meridian travels approximately one minute of geographic latitude in one hour. The length of the internationally agreed nautical mile is 1 852  m . The US adopted the international definition in 1954, having previously used the US nautical mile ( 1 853 .248 m ). The UK adopted the international nautical mile definition in 1970, having previously used the UK Admiralty nautical mile ( 6 080  ft or 1 853 .184 m ). (* = approximate values) The speeds of vessels relative to

308-620: 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,

385-452: A distance in nautical miles on a chart can easily be measured by using dividers and the latitude scales on the sides of the chart. Recent British Admiralty charts have a latitude scale down the middle to make this even easier. Speed is sometimes incorrectly expressed as "knots per hour", which would mean "nautical miles per hour per hour" and thus would refer to acceleration . Prior to 1969, airworthiness standards for civil aircraft in

462-644: 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,

539-457: 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

616-832: A jetty. The paddle steamers between them were estimated to have rescued 26,000 Allied troops during the operation, for the loss of six of them. In Austria only a small paddle steamer fleet operates. There is Gisela from 1872 in Gmunden at the Traunsee , Kaiser Franz Josef I. from 1873 in St. Gilgen at the Lake Wolfgang , Hohentwiel from 1913 in Hard (near Bregenz ) at the Lake Constance and Schönbrunn from 1912 in Linz at

693-473: A large range of cruises in Echuca – from one-hour sightseeing trips to three-night and four-day fully accommodated voyages. She is powered by an authentic steam engine, dating back to 1906. Knot (unit) The knot ( / n ɒ t / ) is a unit of speed equal to one nautical mile per hour, exactly 1.852 km/h (approximately 1.151 mph or 0.514 m/s ). The ISO standard symbol for

770-448: 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

847-559: 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

924-472: 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

1001-477: 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

1078-694: 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

1155-422: A permanent lighthouse facility be built on Anacapa Island. Due to a lack of funding, the installation (an unmanned acetylene beacon on a fifty-foot tower) was not constructed until 1912. The tower was replaced by a lighthouse in 1932. Paddle steamer In the early 19th century, paddle wheels were the predominant way of propulsion for steam-powered boats. In the late 19th century, paddle propulsion

1232-515: A result, many had to wait months to complete the second half of their journey. To fill this growing need for swift passage from Panama to California, shipbuilding activities increased dramatically. Winfield Scott (originally to be named Placer ) was constructed by the shipbuilding company Westervelt and MacKay of New York, and was completed in March 1850. The ship was named for the celebrated United States Army general Winfield Scott (the stern

1309-466: 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

1386-502: 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

1463-419: 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

1540-472: A standard nautical chart using Mercator projection , the horizontal (East–West) scale varies with latitude. On a chart of the North Atlantic, the scale varies by a factor of two from Florida to Greenland. A single graphic scale , of the sort on many maps, would therefore be useless on such a chart. Since the length of a nautical mile, for practical purposes, is equivalent to about a minute of latitude,

1617-541: 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

1694-500: Is 14.40 {\displaystyle 14.40} metres per knot. Although the unit knot does not fit within the SI system, its retention for nautical and aviation use is important because the length of a nautical mile , upon which the knot is based, is closely related to the longitude / latitude geographic coordinate system . As a result, nautical miles and knots are convenient units to use when navigating an aircraft or ship. On

1771-416: 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

1848-658: 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

1925-589: The Danube . Australia has a large collection of authentic and replica paddle steamers and paddle boats operating along the Murray and Darling Rivers, and in other areas around the country. Echuca/Moama has the largest fleet of paddle steamers in Australia, with seven operating commercially, and a large number of smaller privately owned vessels. PS  Adelaide is the oldest wooden-hulled paddle steamer in

2002-486: 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

2079-533: The International Civil Aviation Organization list the knot as permitted for temporary use in aviation, but no end date to the temporary period has been agreed as of 2024 . Until the mid-19th century, vessel speed at sea was measured using a chip log . This consisted of a wooden panel, attached by line to a reel, and weighted on one edge to float perpendicularly to the water surface and thus present substantial resistance to

2156-860: 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

2233-589: The Panama Canal nor the First transcontinental railroad had been constructed, people emigrating to California from the Eastern United States had three main routes of passage. They could travel over land, which was expensive and dangerous, or they could sail the roughly 14,000-mile (23,000 km) route around South America. This was more attractive to some but no less dangerous, due in part to

2310-707: 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

2387-680: 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

2464-581: 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

2541-430: The fluids in which they travel (boat speeds and air speeds ) can be measured in knots. If so, for consistency, the speeds of navigational fluids ( ocean currents , tidal streams , river currents and wind speeds ) are also measured in knots. Thus, speed over the ground (SOG; ground speed (GS) in aircraft) and rate of progress towards a distant point (" velocity made good ", VMG) can also be given in knots. Since 1979,

2695-614: The war effort . The remaining wreckage is considered important from an historical perspective, as it represents a tangible example of mid-19th century shipbuilding. Although much of the wooden hull has long since disintegrated, some of the machinery is still relatively intact. Between 1853 and 1980, more than 140 shipwrecks were documented in the Channel Islands National Park Marine Sanctuary. As of December 2000, twenty sites had been located. The prevailing currents and weather conditions of

2772-506: 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

2849-423: 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

2926-619: 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

3003-473: The Anglican Archbishop of Adelaide, and funded by old boys of Eton (UK). It had a small chapel. Larger gathering were held on riverbanks and in woolsheds. After retirement, it became a fishing boat, then moved to Echuca to be a private houseboat. It also appeared in 'All the rivers' run, reprising its role as a mission boat. PS Alexander Arbuthnot , built 1923 at Koondrook , and named after

3080-467: 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

3157-644: 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

3234-697: 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

3311-510: 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

3388-623: The New York and California Steamship Company in May 1853), the ship's ownership was again transferred on July 8, 1853, this time to the Pacific Mail Steamship Company . Winfield Scott , bound for Panama, departed from San Francisco on the morning of 1 December 1853. In addition to her complement of passengers and crew, the ship was transporting a shipment of gold bullion worth an estimated US$ 2 million. The ship's progress

3465-610: The New York- New Orleans route. In 1852, the ship's ownership was transferred to the New York and San Francisco Steamship Company Line, and she arrived in San Francisco on April 28, 1852. Once there, she began taking gold seekers, nicknamed argonauts, on the Panama Route (between San Francisco and Panama). After the demise of the New York and San Francisco Steamship Company Line (which had been renamed as

3542-543: 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

3619-668: The United States Federal Aviation Regulations specified that distances were to be in statute miles, and speeds in miles per hour. In 1969, these standards were progressively amended to specify that distances were to be in nautical miles, and speeds in knots. The following abbreviations are used to distinguish between various measurements of airspeed : The indicated airspeed is close to the true airspeed only at sea level in standard conditions and at low speeds. At 11 000  m ( 36 000  ft), an indicated airspeed of 300 kn may correspond to

3696-624: 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

In 1987, the California Wreck Divers Club was the subject of a sting operation to discourage salvage divers from bringing up artifacts from the Winfeld Scott and other ships in the Santa Barbara Channel. A coin was brought up from the Winfield Scott that was the major target of the subsequent legal case. Shortly after the wreck, the United States Coast Survey recommended that

3850-478: 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

3927-401: 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

4004-702: 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

4081-600: The former owner of the Arbuthnot Sawmills, works today as a tourist boat at the Port of Echuca. PS  Canberra , built 1913 at Goolwa , is currently operating public cruises in Echuca. Canberra was built for the Conner family of Boundary Bend , as their flagship fishing vessel, but has been in the tourism industry since 1944. PS  Emmylou , a replica steamer, was built in 1982 at Barham , and operates

4158-427: 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

4235-467: 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

4312-417: 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

The same symbol is preferred by the Institute of Electrical and Electronics Engineers ( IEEE ), while kt is also common, especially in aviation, where it is the form recommended by the International Civil Aviation Organization ( ICAO ). The knot is a non- SI unit. The knot is used in meteorology , and in maritime and air navigation. A vessel travelling at 1 knot along

4466-535: 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

Winfield Scott , however, had sustained too much damage and was left in the waters of the channel. The remains of Winfield Scott are located under 25–30 feet (7.6–9.1 m) of water in the Channel Islands National Park and Marine Sanctuary . The wreckage site was verified in 1981 and

4851-417: The rough waters of the Drake Passage . In addition to the inherent dangers of either route, the journey often took as long as six months to complete. The third route involved traversing the jungles of the Isthmus of Panama , then departing via the southern coast of Panama. While this cut the length of the sea journey in half, ships to ferry passengers from Panama to San Francisco were not commonplace. As

4928-622: 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

5005-412: 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,

5082-457: The survivors spent the first night camped on a pinnacle of rock that measured 50 by 25 yards (46 by 23 m). The next day they moved to a larger piece of land on the island. One of the passengers, Asa Cyrus Call, recalled "a terrible jar and crashing of timbers...I hurried out on deck, where my attention was fixed on a wall of towering cliffs, the tops of which were hidden by the fog and darkness and appeared about to fall and crush us. All round

5159-417: The time of the wreck was estimated at 10 knots (19 km/h; 12 mph). She struck the island bow first, and when Capt. Blunt attempted to back away the stern was struck, removing the ship's rudder . With the ship taking on massive amounts of water and unable to steer, all aboard, perhaps as many as 500 people, began scrambling for land. The ship was completely evacuated in approximately two hours, and

An announcement in the October 20 edition of the New York Herald stated that "We understand that no expense has been spared to secure strength, safety and speed..." Her hull was wooden with double iron bracing and was made from White oak , Live oak , Locust , Redcedar and Georgia yellow pine . The steamer, owned by Davis, Brooks and Company, initially transported passengers on
