Propeller
A propeller (colloquially often called a screw if on a ship or an airscrew if on an aircraft) is a device with a rotating hub and radiating blades that are set at a pitch to form a helical spiral which, when rotated, exerts linear thrust upon a working fluid such as water or air. Propellers are used to pump fluid through a pipe or duct, or to create thrust to propel a boat through water or an aircraft through air. The blades are specially shaped so that their rotational motion through the fluid causes a pressure difference between the two surfaces of the blade by Bernoulli's principle which exerts force on the fluid. Most marine propellers are screw propellers with helical blades rotating on a propeller shaft (ship), propeller shaft with an approximately horizontal axis. History Early developments The principle employed in using a screw propeller is derived from sculling. In sculling, a single blade is moved through an arc, from side to side taking care to keep presenting the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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. 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. The term ''steamboat'' is used to refer to smaller, insular, steam-powered boats working on lakes and rivers, particularly riverboats. As using steam became more reliable, steam power became applied to larger, ocean-going vessels. Background Limitations of the Newcomen steam engine Early 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 Newcomen engine also produced a reciprocating or rocking motion because it was designed for pumping. The piston stroke was caused by a water jet i ...

Official Number
Official numbers are ship identifier numbers assigned to merchant ships by their flag state, country of registration. Each country developed its own official numbering system, some on a national and some on a port-by-port basis, and the formats have sometimes changed over time. As an internationally recognized ship identifier, national official numbers have largely been superseded by the IMO number, though flag states still use national systems, which also cover those vessels not subject to the IMO regulations. British official number Beginning in 1855, with the implementation of the Merchant Shipping Act 1854, all British seagoing vessels were assigned an official number to give each ship a unique identity, even after being renamed or changing the port of registry. U.S. official number After the passage of legislation in the United States Congress in 1866, all American ships were required to carve the official number on the main beam; the system was controlled by the Bureau of Sta ...

Barge
Barge nowadays generally refers to a flat-bottomed inland waterway vessel which does not have its own means of mechanical propulsion. The first modern barges were pulled by tugs, but nowadays most are pushed by pusher boats, or other vessels. The term barge has a rich history, and therefore there are many other types of barges. History of the barge Etymology "Barge" is attested from 1300, from Old French ''barge'', from Vulgar Latin ''barga''. The word originally could refer to any small boat; the modern meaning arose around 1480. ''Bark'' "small ship" is attested from 1420, from Old French ''barque'', from Vulgar Latin ''barca'' (400 AD). The more precise meaning of Barque as "three-masted sailing vessel" arose in the 17th century, and often takes the French spelling for disambiguation. Both are probably derived from the Latin ''barica'', from Greek ''baris'' "Egyptian boat", from Coptic ''bari'' "small boat", hieroglyphic Egyptian D58-G29-M17-M17-D21-P1 and similar ''b ...

Sagamore (barge)
The ''Sagamore'' is reported to be the best example of a whaleback barge among Great Lakes shipwrecks. Only 44 whalebacks were ever built, and out of the 26 that sank, only 8 sank in the Great Lakes, most of them being blown up for blocking shipping channels. She sank in 1901 in the shipping lane near the Soo Locks when she was rammed by the steel steamer ''Northern Queen'' in one of Whitefish Bay's notorious fogs. Her captain and two crew members went down with her. Artifacts from her wreck were illegally removed in the 1980s. Her artifacts are now the property of the State of Michigan and are on display as a loan to the Great Lakes Shipwreck Museum. The wreck of the ''Sagamore'' is protected as part of an underwater museum in the Whitefish Point Underwater Preserve. Career The ''SS Sagamore's'' keel was laid 15 December 1891 by the American Steel Barge Company and she was launched 23 July 1892 in Superior, Wisconsin. She was built as 1,601 gross ton whaleback steamer barg ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Whaleback
] A whaleback was a type of cargo steamship of unusual design, with a hull that continuously curved above the waterline from vertical to horizontal. When fully loaded, only the rounded portion of the hull (the "whaleback" proper) could be seen above the waterline. With sides curved in towards the ends, it had a Spoon-shaped bow, spoon bow and a very convex upper deck. It was formerly used on the Great Lakes of Canada and the United States, notably for carrying grain or ore. The sole surviving ship of the "whaleback" design is the , which is docked in Superior, Wisconsin as a museum ship. The term developed in common usage in response to the ship's appearance when fully loaded. A total of 44 such vessels were constructed from 1887 to 1898. All but two were built initially as lake freighters for service on the Great Lakes. Six were built at Duluth, Minnesota; 33 were built at West Superior, Wisconsin; 2 at Brooklyn, New York; one at Everett, Washington; and one at Sunderland, Eng ...

Yacht
A yacht is a sailing or power vessel used for pleasure, cruising, or racing. There is no standard definition, though the term generally applies to vessels with a cabin intended for overnight use. To be termed a , as opposed to a , such a pleasure vessel is likely to be at least in length and may have been judged to have good aesthetic qualities. The Commercial Yacht Code classifies yachts and over as . Such yachts typically require a hired crew and have higher construction standards. Further classifications for large yachts are: —carrying no more than 12 passengers, —solely for the pleasure of the owner and guests, or by flag, the country under which it is registered. A superyacht (sometimes ) generally refers to any yacht (sail or power) longer than . Racing yachts are designed to emphasize performance over comfort. Charter yachts are run as a business for profit. As of 2020 there were more than 15,000 yachts of sufficient size to require a professional crew. Etymology ...

Bulk Carrier
A bulk carrier or bulker is a merchant ship specially designed to transport unpackaged bulk cargo — such as grains, coal, ore, steel coils, and cement — in its cargo holds. Since the first specialized bulk carrier was built in 1852, economic forces have led to continued development of these ships, resulting in increased size and sophistication. Today's bulk carriers are specially designed to maximize capacity, safety, efficiency, and durability. Today, bulk carriers make up 21 percent of the world's merchant fleets, and they range in size from single-hold mini-bulk carriers to mammoth ore ships able to carry 400,000 metric tons of deadweight (DWT). A number of specialized designs exist: some can unload their own cargo, some depend on port facilities for unloading, and some even package the cargo as it is loaded. Over half of all bulk carriers have Greek, Japanese, or Chinese owners, and more than a quarter are registered in Panama. South Korea is the largest single bu ...

World Ship Society
The World Ship Society (WSS) is an international society devoted to maritime and naval history. Founded in 1946 as Ship News Club in order to distribute shipping information to correspondents, the society now has thousands of members in dozens of branches across the world. It publishes the monthly magazine ''Marine News'' and the quarterly magazine ''Warships'' for its membership. History In 1946 Michael Crowdy started a mailing list in the United Kingdom. In order to share a growing amount of information regarding ships, Crowdy founded the Ships News Club and published two news lists covering all ships in alphabetical order. These two lists, published in 1947, are acknowledged by the WSS to be the first two editions of the ''Marine News''. From 50 Correspondents at the start of 1947, by the end of the year members of the Ship News Club numbered 200 and 330 in July 1948. Notable amongst its early members were the then editor of Jane's Fighting Ships, Francis McMurtrie, and fo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
