Steering Wheel (ship)
A ship's wheel or boat's wheel is a device used aboard a ship, boat, submarine, or airship, with which a helmsman steers the vessel and controls its course. Together with the rest of the steering mechanism, it forms part of the helm (the term ''helm'' can mean the wheel alone, or the entire mechanism by which the rudder is controlled). It is connected to a mechanical, electric servo, or hydraulic system which alters the horizontal angle of the vessel's rudder relative to its hull. In some modern ships the wheel is replaced with a simple toggle that remotely controls an electro-mechanical or electro-hydraulic drive for the rudder, with a rudder position indicator presenting feedback to the helmsman. History Until the invention of the ship's wheel, the helmsman relied on a tiller—a horizontal bar fitted directly to the top of the rudder post—or a whipstaff—a vertical stick acting on the arm of the ship's tiller. Near the start of the 18th century, a large number of vessel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Balusters
A baluster () is an upright support, often a vertical moulded shaft, square, or lathe-turned form found in stairways, parapets, and other architectural features. In furniture construction it is known as a spindle. Common materials used in its construction are wood, stone, and less frequently metal and ceramic. A group of balusters supporting a guard railing, coping, or ornamental detail is known as a balustrade. The term baluster shaft is used to describe forms such as a candlestick, upright furniture support, and the stem of a brass chandelier. The term banister (also bannister) refers to a baluster or to the system of balusters and handrail of a stairway. It may be used to include its supporting structures, such as a supporting newel post. In the UK, there are different height requirements for domestic and commercial balustrades, as outlined in Approved Document K. Etymology According to the ''Oxford English Dictionary'', "baluster" is derived through the , from , from '' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Officer Of The Watch
Watchkeeping or watchstanding is the assignment of sailors to specific roles on a ship to operate it continuously. These assignments, also known at sea as ''watches'', are constantly active as they are considered essential to the safe operation of the vessel and also allow the ship to respond to emergencies and other situations quickly. These watches are divided into work periods to ensure that the roles are always occupied at all times, while those members of the crew who are assigned to work during a watch are known as ''watchkeepers''. On a typical seafaring vessel, be it naval or merchant, personnel "keep a watch" in various locations and duties across the ship, such as the Bridge (nautical), bridge and engine room. Typical bridge watchkeepers include a lookout and a deck officer who is responsible for the safe navigation of the ship; whereas in the engine room, an engine officer ensures that running machinery continues to operate within tolerances.

Captain (nautical)
A sea captain, ship's captain, captain, master, or shipmaster, is a high-grade licensed mariner who holds ultimate command and responsibility of a merchant vessel. The captain is responsible for the safe and efficient operation of the ship, including its seaworthiness, safety and security, cargo operations, navigation, crew management, and legal compliance, and for the persons and cargo on board. Duties and functions The captain ensures that the ship complies with local and international laws and complies also with company and flag state policies. The captain is ultimately responsible, under the law, for aspects of operation such as the safe navigation of the ship, its cleanliness and seaworthiness, safe handling of all cargo, management of all personnel, inventory of ship's cash and stores, and maintaining the ship's certificates and documentation. One of a shipmaster's particularly important duties is to ensure compliance with the vessel's security plan, as required by th ...

Starboard
Port and starboard are Glossary of nautical terms (M-Z), nautical terms for watercraft and spacecraft, referring respectively to the left and right sides of the vessel, when aboard and facing the Bow (watercraft), bow (front). Vessels with bilateral Symmetry (geometry), symmetry have left and right halves which are mirror images of each other. One asymmetric feature is where access to a boat, ship, or aircraft is at the side; it is usually only on the port side (hence the name). Side Port side and starboard side respectively refer to the left and right sides of the vessel, when aboard and facing the bow. The port and starboard sides of the vessel always refer to the same portion of the vessel's structure, and do not depend on the position of someone aboard the vessel. The port side is the side to the left of an observer aboard the vessel and , towards the direction the vessel is heading when underway in the forward direction. The starboard side is to the right of such an obser ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sheave
Sheave without a rope A pulley is a wheel on an axle or shaft enabling a taut cable or belt passing over the wheel to move and change direction, or transfer power between itself and a shaft. A pulley may have a groove or grooves between flanges around its circumference to locate the cable or belt. The drive element of a pulley system can be a rope, cable, belt, or chain. History The earliest evidence of pulleys dates back to Ancient Egypt in the Twelfth Dynasty (1991–1802 BC) and Mesopotamia in the early 2nd millennium BC. In Roman Egypt, Hero of Alexandria (c. 10–70 AD) identified the pulley as one of six simple machines used to lift weights. Pulleys are assembled to form a block and tackle in order to provide mechanical advantage to apply large forces. Pulleys are also assembled as part of belt and chain drives in order to transmit power from one rotating shaft to another. Plutarch's ''Parallel Lives'' recounts a scene where Archimedes proved the effectiveness of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wheel And Rudder Assembly (fixed)
A wheel is a rotating component (typically circular in shape) that is intended to turn on an axle bearing. The wheel is one of the key components of the wheel and axle which is one of the six simple machines. Wheels, in conjunction with axles, allow heavy objects to be moved easily facilitating movement or transportation while supporting a load, or performing labor in machines. Wheels are also used for other purposes, such as a ship's wheel, steering wheel, potter's wheel, and flywheel. Common examples can be found in transport applications. A wheel reduces friction by facilitating motion by rolling together with the use of axles. In order for a wheel to rotate, a moment must be applied to the wheel about its axis, either by gravity or by the application of another external force or torque. Terminology The English word ''wheel'' comes from the Old English word , from Proto-Germanic , from Proto-Indo-European , an extended form of the root . Cognates within Indo-European in ...

Hardwood
Hardwood is wood from Flowering plant, angiosperm trees. These are usually found in broad-leaved temperate and tropical forests. In temperate and boreal ecosystem, boreal latitudes they are mostly deciduous, but in tropics and subtropics mostly evergreen. Hardwood (which comes from angiosperm trees) contrasts with softwood (which is from gymnosperm trees). Characteristics Hardwoods are produced by Flowering plant, angiosperm trees that reproduce by flowers, and have broad leaves. Many species are deciduous. Those of temperate regions lose their leaves every autumn as temperatures fall and are dormant in the winter, but those of tropical regions may shed their leaves in response to seasonal or sporadic periods of drought. Hardwood from deciduous species, such as oak, normally shows annual dendrochronology, growth rings, but these may be absent in some tropical timber, tropical hardwoods. Hardwoods have a more complex structure than softwoods and are often much slower growing ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mahogany
Mahogany is a straight- grained, reddish-brown timber of three tropical hardwood species of the genus ''Swietenia'', indigenous to the AmericasBridgewater, Samuel (2012). ''A Natural History of Belize: Inside the Maya Forest''. Austin: University of Texas Press. pp. 164–165. . and part of the pantropical chinaberry family, Meliaceae. Mahogany is used commercially for a wide variety of goods, due to its coloring and durable nature. It is naturally found within the Americas, but has also been imported to plantations across Asia and Oceania. The mahogany trade is believed to have started as early as the 16th century and flourished throughout the 17th and 18th centuries. In some countries, mahogany is classified as an invasive species. Mahogany is wood from any of three tree species: Honduran or big-leaf mahogany ('' Swietenia macrophylla''), West Indian or Cuban mahogany ('' Swietenia mahagoni''), and '' Swietenia humilis''. Honduran mahogany is the most widespread and the only g ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
