Stockless Anchor
A stockless anchor (or "patent anchor") is a streamlined derivation of the traditional Admiralty anchor used aboard large ships. Patented in England in 1821, it eliminated the stock of the Admiralty, making it both easier to handle and stow. Though it did not hold as well as an Admiralty, the trade-off proved acceptable and the stockless anchor became widely popular, and remains so today. Design The stockless anchor is an improved version of the Admiralty anchor Admiralty most often refers to: *Admiralty, Hong Kong *Admiralty (United Kingdom), military department in command of the Royal Navy from 1707 to 1964 *The rank of admiral *Admiralty law Admiralty can also refer to: Buildings * Admiralty, Tra ... it is derived from. It has two flukes that pivot on the same plane perpendicular to the shank. The weight of the shank and accompanying chain, or the shank angled under tension, keep the anchor laying flat on the sea floor. Performance The stockless anchor is a sim ...

Amoco Cadiz Anchor
Amoco () is a brand of fuel stations operating in the United States, and owned by BP since 1998. The Amoco Corporation was an American chemical and oil company, founded by Standard Oil Company in 1889 around a refinery in Whiting, Indiana, and was officially the Standard Oil Company of Indiana until 1985. Originally part of the Standard Oil Company trust, it focused on producing gasoline for the new automobile market. In 1911, as part of the break-up of the Standard Oil trust, it became an independent corporation. Incorporated in Indiana, it was headquartered in Chicago, and formally adopted the name Amoco in 1985. Although the Amoco Corporation merged in 1998 into BP Amoco, the Amoco name was resurrected in 2017 as a brand that service station owners could choose to use when they purchased supplies from BP in selected areas of the United States. In 1925, Standard Oil of Indiana absorbed the American Oil Company, founded in Baltimore in 1910, and incorporated in 1922, b ...

Anchor
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). Anchors can either be temporary or permanent. Permanent anchors are used in the creation of a mooring, and are rarely moved; a specialist service is normally needed to move or maintain them. Vessels carry one or more temporary anchors, which may be of different designs and weights. A sea anchor is a drag device, not in contact with the seabed, used to minimise drift of a vessel relative to the water. A drogue is a drag device used to slow or help steer a vessel running before a storm in a following or overtaking sea, or when crossing a bar in a breaking sea.. Overview Anchors achieve holding power either by "hooking" into the seabed, or mass, or a combination of the two. Permanent moorings use large mass ...

Watercraft Components
Any vehicle used in or on water as well as underwater, including boats, ships, hovercraft and submarines, is a watercraft, also known as a water vessel or waterborne vessel. A watercraft usually has a propulsive capability (whether by sail, oar, paddle, or engine) and hence is distinct from a stationary device, such as a pontoon, that merely floats. Types Most watercraft may be described as either a ship or a boat. However, numerous items, including surfboards, underwater robots, seaplanes and torpedoes, may be considered neither ships nor boats. Although ships are typically larger than boats, the distinction between those two categories is not one of size per se. *Ships are typically large ocean-going vessels; whereas boats are smaller, and typically travel most often on inland or coastal waters. *A rule of thumb says "a boat can fit on a ship, but a ship can't fit on a boat", and a ship ''usually'' has sufficient size to carry its own boats, such as lifeboats, dinghie ...
