A boat hook is part of boating equipment. Its most common use is as a docking and undocking aid. It may be similar to a pike pole, however it commonly has a blunt tip, for pushing during undocking, with a hook for docking. In addition, it may have a line attached to the other end, which may have a ring for this purpose. [1]
It may be also used for pulling things out of water, such as debris or people, as well as for other fetching tasks and holding-off from other boats or landings.
Evidence of boat hooks has been found from ancient Rome and the painting Christ in the Storm on the Sea of Galilee, by Rembrandt van Rijn was painted in 1633 and clearly shows one in its familiar form.
A traditional European boat hook pole is around 1.8- 2.4M and is typically made of ash- one of the best woods for poles, such as spears etc. It would have a brass hook- a non-rusting metal common on traditional boat fittings. The hook end would usually have a hook on one side for pulling and catching things, plus a rounded point for pushing things. [2]
Although the traditional boat hook is still available, various different materials, such as aluminium and even a rolled up polymer are now available [3] . Although the boat hook is a general purpose reaching and holding-off tool on boats, there are more specialised forms, such as the Recovery Pole [4] designed for length rather than the rigid strength of a boat hook.
In the Royal Navy, during ceremonial occasions the Ceremonial Boat Hook Drill must be performed during berthing and unberthing. [5]
An anchor is a device, normally made of metal, used to secure a vessel to the bed of a body of water to prevent the craft from drifting due to wind or current. The word derives from Latin ancora, which itself comes from the Greek ἄγκυρα (ankȳra).
A dinghy is a type of small boat, often carried or towed by a larger vessel for use as a tender. Utility dinghies are usually rowboats or have an outboard motor. Some are rigged for sailing but they differ from sailing dinghies, which are designed first and foremost for sailing. A dinghy's main use is for transfers from larger boats, especially when the larger boat cannot dock at a suitably-sized port or marina.
An oil well is a drillhole boring in Earth that is designed to bring petroleum oil hydrocarbons to the surface. Usually some natural gas is released as associated petroleum gas along with the oil. A well that is designed to produce only gas may be termed a gas well. Wells are created by drilling down into an oil or gas reserve that is then mounted with an extraction device such as a pumpjack which allows extraction from the reserve. Creating the wells can be an expensive process, costing at least hundreds of thousands of dollars, and costing much more when in hard to reach areas, e.g., when creating offshore oil platforms. The process of modern drilling for wells first started in the 19th century, but was made more efficient with advances to oil drilling rigs during the 20th century.
A mooring is any permanent structure to which a vessel may be secured. Examples include quays, wharfs, jetties, piers, anchor buoys, and mooring buoys. A ship is secured to a mooring to forestall free movement of the ship on the water. An anchor mooring fixes a vessel's position relative to a point on the bottom of a waterway without connecting the vessel to shore. As a verb, mooring refers to the act of attaching a vessel to a mooring.
Backstroke or back crawl is one of the four swimming styles used in competitive events regulated by FINA, and the only one of these styles swum on the back. This swimming style has the advantage of easy breathing, but the disadvantage of swimmers not being able to see where they are going. It also has a different start from the other three competition swimming styles. The swimming style is similar to an upside down front crawl or freestyle. Both backstroke and front crawl are long-axis strokes. In individual medley backstroke is the second style swum; in the medley relay it is the first style swum.
Human swimming typically consists of repeating a specific body motion or swimming stroke to propel that body forward. There are many kinds of strokes, each defining a different swimming style or crawl.
In computing, a docking station or port replicator (hub) or dock provides a simplified way to plug-in a mobile device, such as a laptop, to common peripherals. Because a wide range of dockable devices—from mobile phones to wireless mouse—have different connectors, power signaling, and uses, docks are unstandardized and are therefore often designed for a specific type of device.
A chuck is a specialized type of clamp used to hold an object with radial symmetry, especially a cylinder. In a drill, a mill and a transmission, a chuck holds the rotating tool; in a lathe, it holds the rotating workpiece.
A machine taper is a system for securing cutting tools or toolholders in the spindle of a machine tool or power tool. A male member of conical form fits into the female socket, which has a matching taper of equal angle.
In competitive rowing, the following specialized terms are important in the corresponding aspects of the sport:
A davit is any of various crane-like devices used on a ship for supporting, raising, and lowering equipment such as boats and anchors.
A punt is a flat-bottomed boat with a square-cut bow, designed for use in small rivers and shallow water. Punting is boating in a punt; the punter propels the punt by pushing against the river bed with a pole. Punts were originally built as cargo boats and as platforms for fowling and for fishing, such as angling; whereas now punting is boating for pleasure.
A butt joint is a technique in which two pieces of material are joined by simply placing their ends together without any special shaping. The name "butt joint" comes from the way the material is joined. The butt joint is the simplest joint to make since it merely involves cutting the material to the appropriate length and butting them together. It is also the weakest because unless some form of reinforcement is used, it relies upon glue or welding alone to hold it together. Because the orientation of the material usually presents only one end to a long gluing or welding surface, the resulting joint is inherently weak.
A pike pole is a long metal-topped wooden, aluminium or fiberglass pole used for reaching, hooking and/or pulling on another object. They are variously used in boating, construction, logging, rescue and recovery, power line maintenance, and firefighting.
Lavvu is a temporary dwelling used by the Sami people of northern extremes of Northern Europe. It has a design similar to a Native American tipi but is less vertical and more stable in high winds. It enables the indigenous cultures of the treeless plains of northern Scandinavia and the high arctic of Eurasia to follow their reindeer herds. It is still used as a temporary shelter by the Sami, and increasingly by other people for camping. It should not be confused with the goahti, another type of Sami dwelling, or the Finnish laavu.
A fishing vessel is a boat or ship used to catch fish in the sea, or on a lake or river. Many different kinds of vessels are used in commercial, artisanal and recreational fishing.
Horse harness is a device that connects a horse to a vehicle or another type of load.
Fishing techniques are methods for catching fish. The term may also be applied to methods for catching other aquatic animals such as molluscs and edible marine invertebrates.
Soyuz TMA-20 was a human spaceflight to the International Space Station (ISS) and was part of the Soyuz programme. It lifted off from the Baikonur Cosmodrome in Kazakhstan on December 15, 2010, and docked with the ISS two days later. The three-person crew of Soyuz TMA-20 – Dmitri Kondratyev, Catherine Coleman and Paolo Nespoli – represented the ISS partner organizations of Roscosmos, NASA and the European Space Agency (ESA). Soyuz TMA-20's crew represented half of the members of Expedition 27; the other three members of the expedition arrived at the station on board Soyuz TMA-21 on April 6, 2011. The COSPAR ID of Soyuz TMA-20 was 2010-067A. It is ISS flight 25S.
A hook in ten-pin bowling is a ball that rolls in a curving pattern. The purpose of the hook is to give the ball a better angle at the 1-3 pocket (right-handers) or 1-2 pocket (left-handers.) to achieve a strike. When a ball is rolled straight, hitting the pocket must be precise. By hooking the ball, the ball will hit the pins with more force, producing better carry - especially on the 5-pin during a strike ball. Straight roll - even when it hits the pocket, will tend to leave a tap such as the 5-pin on a light hit, or the 10-pin if the ball was just slightly right of center pocket or with inadequate entry angle. A hook ball can achieve strikes with less precise hits.
