Chain Boat
A chain boat,John MacGregor (1867). ''The voyage alone in the yawl "Rob Roy": from London to Paris, and back etc.'', London: Maranda merrill, Son and Marston, pp. 97-99. chain tug or chain-ship was a type of river craft, used in the second half of the 19th century and first half of the 20th century on many European rivers, that made use of a steel chain laid along the riverbed for its propulsion. As a result, there was a continual movement of the chain, that made control more difficult in more dangerous sections of the river, such as rapids. In particular, reinforced chain sections that were deliberately used, moved continually upstream. Also jettisoning the chain temporarily when two chain boats met was relatively difficult due to the multiple windings of the chain round the two drums. Many of the chain steamers without their own auxiliary engines had different gearing for moving upstream and downstream. When travelling upstream, it was designed for higher traction; when travelli ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Paddle Steamer
A paddle steamer 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 In the late 19th century, paddle propulsion was largely superseded by the propeller, screw propeller and other marine propulsion systems that have a higher efficiency, especially in rough or open water.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. Paddle wheels The paddle wheel is a large steel framework wheel. The outer edge of the wheel is fitted with numerous, regularly spaced paddle blades (called floats or buckets). The bottom quarter or so of the wheel travels under wate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Saale
The Saale (), also known as the Saxon Saale ( ) and Thuringian Saale (), is a river in Germany and a left-bank tributary of the Elbe. It is not to be confused with the smaller Fränkische Saale, Franconian Saale, a right-bank tributary of the Main (river), Main, or the Saale (Leine), Saale in Lower Saxony, a tributary of the Leine. Etymology The name ''Saale'' comes from the Proto-Indo-European language, Proto-Indo-European root wikt:Reconstruction:Proto-Indo-European/sélos, *''séles'' 'marsh', akin to Welsh language, Welsh ''hêl, heledd'' 'river meadow', Cornish language, Cornish ''heyl'' 'estuary', Ancient Greek, Greek ''hélos'' 'marsh, meadow', Sanskrit ''sáras'' 'lake, pond', Sarasvati River, ''Sárasvati'' 'sacred river', Old Persian ''Harauvati'' 'Harut River, Hārūt River; Arachosia', Avestan ''Haraxvatī'', idem. It may also be related to the Indo-European root *''sal'', "salt". The Slavic name of the Saale, ''Solawa'', still found in Sorbian language, Sorbian tex ...

Draught (ship)
The draft or draught of a ship is a determined depth of the vessel below the waterline, measured vertically to its hull (watercraft), hull's lowest—its propellers, or keel, or other reference point. Draft varies according to the loaded condition of the ship. A deeper draft means the ship will have greater vertical depth below the waterline. Draft is used in under keel clearance calculations, where the draft is calculated with the available depth of water (from Electronic navigational charts) to ensure the ship can navigate safely, without grounding. Navigators can determine their draught by calculation or by visual observation (of the ship's painted Load line (vessel), load lines). Related terminology A ship's draft/draught is the "depth of the vessel below the waterline measured vertically to the lowest part of the hull (watercraft), hull, propellers, or other reference point". That is, the draft or draught is the maximum depth (coordinate), depth of any part of the vessel, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Montereau-Fault-Yonne
Montereau-Fault-Yonne (, before 1992: ''Montereau-Faut-Yonne''), or simply Montereau, is a Communes of France, commune in the Seine-et-Marne Departments of France, department in the Île-de-France Regions of France, region in north-central France. Geography Montereau-Fault-Yonne straddles the confluence of the rivers Yonne (river), Yonne and Seine at the far south-east of the Île-de-France region, 70 km southeast of its administrative centre, Paris.

Steamboat
A steamboat is a boat that is marine propulsion, propelled primarily by marine steam engine, steam power, typically driving propellers or Paddle steamer, paddlewheels. The term ''steamboat'' is used to refer to small steam-powered vessels working on lakes, rivers, and in short-sea shipping. The development of the steamboat led to the larger steamship, which is a seaworthy and often ocean-going ship. Steamboats sometimes use the ship prefix, prefix designation SS, S.S. or S/S (for 'Screw Steamer') or PS (for 'Paddle Steamer'); however, these designations are most often used for steamships. Background Limitations of the Newcomen steam engine The first steamboat designs used Newcomen atmospheric engine, Newcomen steam engines. These engines were large, heavy, and produced little power, which resulted in an unfavorable power-to-weight ratio. The heavy weight of the Newcomen engine required a structurally strong boat, and the reciprocating motion of the engine beam required a compli ...
