Anchor Shipping And Foundry Company
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 masses (common ...

Kotwica SS Poznań
The ''Kotwica'' (; Polish for "Anchor") was a World War II emblem of the Polish Underground State and ''Armia Krajowa'' (Home Army, or ''AK''). It was created in 1942 by members of the ''AK'' Wawer Minor sabotage unit, as an easily usable emblem for the Polish struggle to regain independence. The initial meaning of the initials PW was ''Pomścimy Wawer'' ("We shall avenge Wawer"). This was a reference to the Wawer massacre (26–27 December 1939), which was considered to be one of the first large scale massacres of Polish civilians by German troops in occupied Poland. At first, Polish scouts from sabotage groups painted the whole phrase upon walls. However, it was soon abbreviated to the letters PW, which over time came to symbolise the phrase ''Polska Walcząca'' ("Poland Fighting"). Early in 1942, the AK organised a contest to design an emblem to represent the resistance movement, and the winning design ''(pictured)'' by Anna Smoleńska, a member of the Gray Ranks who herself ...

Chain
A chain is a serial assembly of connected pieces, called links, typically made of metal, with an overall character similar to that of a rope in that it is flexible and curved in compression but linear, rigid, and load-bearing in tension. A chain may consist of two or more links. Chains can be classified by their design, which can be dictated by their use: * Those designed for lifting, such as when used with a hoist; for pulling; or for securing, such as with a bicycle lock, have links that are torus shaped, which make the chain flexible in two dimensions (the fixed third dimension being a chain's length). Small chains serving as jewellery are a mostly decorative analogue of such types. * Those designed for transferring power in machines have links designed to mesh with the teeth of the sprockets of the machine, and are flexible in only one dimension. They are known as roller chains, though there are also non-roller chains such as block chains. Two distinct chains can be co ...

Cathead
A cathead is a large wooden beam located on either side of the bow of a sailing ship, and angled forward at roughly 45 degrees. The beam is used to support the ship's anchor when raising it (weighing anchor) or lowering it (letting go), and for carrying the anchor on its stock-end when suspended outside the ship's side. The cathead is furnished with sheaves at the outer end, and the inner end (which is called the cat's-tail) fits down on the cat-beam. The shank painter is a short rope or chain by which the shank of an anchor is held fast to a ship's side when not in use. The process of securing the anchor is called ''catting and fishing'' it. The cat stopper also fastens the anchor on. The purpose of the cathead is to provide both a heavy enough beam to support the massive weight of the anchor, and to hold the metal anchor away from the wooden side of the ship to prevent damage when the anchor is being raised from the water. The stockless anchor made the cathead obsolete. In ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hawsepipe
Hawsehole is a nautical term for a small hole in the hull of a ship through which '' hawsers'' may be passed. It is also known as a cat hole.

Shackle
A shackle (or shacklebolt), also known as a gyve, is a U-shaped piece of metal secured with a clevis pin or bolt across the opening, or a hinged metal loop secured with a quick-release locking pin mechanism. The term also applies to handcuffs and other similarly conceived restraint devices that function in a similar manner. Shackles are the primary connecting link in all manner of rigging systems, from boats and ships to industrial crane rigging, as they allow different rigging subsets to be connected or disconnected quickly. A shackle is also the similarly shaped piece of metal used with a locking mechanism in padlocks. A carabiner is a type of shackle used in mountaineering. Types Bow shackle With a larger "O" shape to the loop, this shackle can take loads from many directions without developing as much side load. However, the larger shape to the loop does reduce its overall strength. Also referred to as an anchor shackle. D-shackle Also known as a chain shackle, D-sh ...

Ladby Ship
The Ladby ship is a major ship burial at the village of Ladby near Kerteminde in Denmark. It is of the type also represented by the boat chamber grave of Hedeby and the ship burials of Oseberg, Borre, Gokstad and Tune in South Norway, all of which date back to the 9th and 10th centuries. It is the only ship burial from the Viking Age discovered in Denmark (Hedeby was a Danish Viking settlement, but today is located in Germany). It has been preserved at the site where it was discovered, which today is part of a museum. Discovery The grave is situated within an otherwise unremarkable burial site from the Viking Age. Excavations revealed an abundance of grave goods consisting of both objects and animals. It has been dated to the early 10th century, based on a gilded link of bronze for a dog-harness, decorated in the Jelling style, found there. . The grave had been extensively damaged. Since only a few small human bones were found, researchers have concluded that the site is a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nemi Ships
The Nemi ships were two ships, one larger than the other, built under the reign of the Roman emperor Caligula in the 1st century CE on Lake Nemi. Although the purpose of the ships is only speculated upon, the larger ship was an elaborate floating palace, which contained quantities of marble, mosaic floors, heating and plumbing, and amenities such as baths. Both ships featured technology thought to have been developed historically much later. It has been stated that the emperor was influenced by the lavish lifestyles of the Hellenistic rulers of Syracuse and Ptolemaic Egypt. Recovered from the lake bed in 1929, the ships were destroyed by fire in 1944 during World War II. Location Lake Nemi ( it, Lago di Nemi, la, Nemorensis Lacus) is a small circular volcanic lake in the Lazio region of Italy, south of Rome. It has a surface of and a maximum depth of . There is considerable speculation regarding why the emperor Caligula chose to build two large ships on such a small lak ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stephanus Of Byzantium
Stephanus or Stephan of Byzantium ( la, Stephanus Byzantinus; grc-gre, Στέφανος Βυζάντιος, ''Stéphanos Byzántios''; centuryAD), was a Byzantine grammarian and the author of an important geographical dictionary entitled ''Ethnica'' (). Only meagre fragments of the dictionary survive, but the epitome is extant, compiled by one Hermolaus, not otherwise identified. Life Nothing is known about the life of Stephanus, except that he was a Greek grammarian who was active in Constantinople, and lived after the time of Arcadius and Honorius, and before that of Justinian II. Later writers provide no information about him, but they do note that the work was later reduced to an epitome by a certain Hermolaus, who dedicated his epitome to Justinian; whether the first or second emperor of that name is meant is disputed, but it seems probable that Stephanus flourished in Byzantium in the earlier part of the sixth century AD, under Justinian I. The ''Ethnica'' Even as an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
