Bow (nautical)
The bow () is the forward part of the hull of a ship or boat, the point that is usually most forward when the vessel is underway. The aft end of the boat is the stern. Prow may be used as a synonym for bow or it may mean the forward-most part of the bow above the waterline. Function A ship's bow should be designed to enable the hull to pass efficiently through the water. Bow shapes vary according to the speed of the boat, the seas or waterways being navigated, and the vessel's function. Where sea conditions are likely to promote pitching, it is useful if the bow provides reserve buoyancy; a flared bow (a raked stem with flared topsides) is ideal to reduce the amount of water shipped over the bow. Ideally, the bow should reduce the resistance and should be tall enough to prevent water from regularly washing over the top of it. Large commercial barges on inland waterways rarely meet big waves and may have remarkably little freeboard at the bow, whereas fast military vess ...

Viking
Vikings ; non, víkingr is the modern name given to seafaring people originally from Scandinavia (present-day Denmark, Norway and Sweden), who from the late 8th to the late 11th centuries raided, pirated, traded and settled throughout parts of Europe.Roesdahl, pp. 9–22. They also voyaged as far as the Mediterranean Sea, Mediterranean, North Africa, Volga Bulgaria, the Middle East, and Greenland, North America. In some of the countries they raided and settled in, this period is popularly known as the Viking Age, and the term "Viking" also commonly includes the inhabitants of the Scandinavian homelands as a collective whole. The Vikings had a profound impact on the Early Middle Ages, early medieval history of Scandinavia, the History of the British Isles, British Isles, France in the Middle Ages, France, Viking Age in Estonia, Estonia, and Kievan Rus'. Expert sailors and navigators aboard their characteristic longships, Vikings established Norse settlem ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Figurehead (object)
A figurehead is a carved wooden decoration found at the bow of ships, generally of a design related to the name or role of a ship. They were predominant between the 16th and 20th centuries, and modern ships' badges fulfill a similar role. History Although earlier ships had often had some form of bow ornamentation (e.g. the eyes painted on the bows of Greek and Phoenician galleys, the Roman practice of putting carvings of their deities on the bows of their galleys, and the Viking ships of ca. A.D. 800–1100), the general practice was introduced with the galleons of the 16th century, as the figurehead as such could not come to be until ships had an actual stemhead structure on which to place it. The menacing appearance of toothy and bug-eyed figureheads on Viking ships were considered a form of apotropaic magic, serving the function of warding off evil spirits. The Egyptians placed figures of holy birds on the prow while the Phoenicians used horses representing speed. The Ancie ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Deck (ship)
A deck is a permanent covering over a compartment or a hull of a ship. On a boat or ship, the primary or upper deck is the horizontal structure that forms the "roof" of the hull, strengthening it and serving as the primary working surface. Vessels often have more than one level both within the hull and in the superstructure above the primary deck, similar to the floors of a multi-storey building, that are also referred to as decks, as are certain compartments and decks built over specific areas of the superstructure. Decks for some purposes have specific names. Structure The main purpose of the upper or primary deck is structural, and only secondarily to provide weather-tightness and support people and equipment. The deck serves as the lid to the complex box girder which can be identified as the hull. It resists tension, compression, and racking forces. The deck's scantling is usually the same as the topsides, or might be heavier if the deck is expected to carry heavier loads ...

Bow (rowing)
In rowing, the bow (or bowman or bowperson) is the rower seated closest to the bow of the boat, which is the forward part of the boat. The other end of the boat is called the stern, and the rower seated there is called the stroke. In a bow-coxed boat, the coxswain is closest to the boat's bow, but the rower closest to the bow is still considered the "bow." Bow seat When the boat has more than one rower, the rower closest to the bow of the boat is known as "bow". In coxless boats, bow is usually the person who keeps an eye on the water behind themselves to avoid accidents. The rower at the opposite end of the boat is referred to as stroke. Bow side Bow side refers to the starboard side of the boat which is on the right hand side of a cox facing forwards but on the left-hand side of a rower facing backwards. The usage derives from the tradition of having the bow rower's oar be on the starboard or right side of the boat. In Cornish pilot gig The Cornish pilot gig is a six-o ...

Boat Building
Boat building is the design and construction of boats and their systems. This includes at a minimum a hull, with propulsion, mechanical, navigation, safety and other systems as a craft requires. Construction materials and methods Wood Wood is the traditional boat building material used for hull and spar construction. It is buoyant, widely available and easily worked. It is a popular material for small boats (of e.g. length; such as dinghies and sailboats). Its abrasion resistance varies according to the hardness and density of the wood and it can deteriorate if fresh water or marine organisms are allowed to penetrate the wood. Woods such as Teak, Totara and some cedars have natural chemicals which prevent rot whereas other woods, such as Pinus radiata, will rot very quickly. The hull of a wooden boat usually consists of planking fastened to frames and a keel. Keel and frames are traditionally made of hardwoods such as oak while planking can be oak but is more often softw ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Old English
Old English (, ), or Anglo-Saxon, is the earliest recorded form of the English language, spoken in England and southern and eastern Scotland in the early Middle Ages. It was brought to Great Britain by Anglo-Saxon settlement of Britain, Anglo-Saxon settlers in the mid-5th century, and the first Old English literature, Old English literary works date from the mid-7th century. After the Norman conquest of 1066, English was replaced, for a time, by Anglo-Norman language, Anglo-Norman (a langues d'oïl, relative of French) as the language of the upper classes. This is regarded as marking the end of the Old English era, since during this period the English language was heavily influenced by Anglo-Norman, developing into a phase known now as Middle English in England and Early Scots in Scotland. Old English developed from a set of Anglo-Frisian languages, Anglo-Frisian or Ingvaeonic dialects originally spoken by Germanic peoples, Germanic tribes traditionally known as the Angles, Sa ...

Old Norse
Old Norse, Old Nordic, or Old Scandinavian, is a stage of development of North Germanic languages, North Germanic dialects before their final divergence into separate Nordic languages. Old Norse was spoken by inhabitants of Scandinavia and their Viking expansion, overseas settlements and chronologically coincides with the Viking Age, the Christianization of Scandinavia and the consolidation of Scandinavian kingdoms from about the 7th to the 15th centuries. The Proto-Norse language developed into Old Norse by the 8th century, and Old Norse began to develop into the modern North Germanic languages in the mid-to-late 14th century, ending the language phase known as Old Norse. These dates, however, are not absolute, since written Old Norse is found well into the 15th century. Old Norse was divided into three dialects: Old West Norse, ''Old West Norse'' or ''Old West Nordic'' (often referred to as ''Old Norse''), Old East Norse, ''Old East Norse'' or ''Old East Nordic'', and ''Ol ...

Middle Dutch
Middle Dutch is a collective name for a number of closely related West Germanic dialects whose ancestor was Old Dutch. It was spoken and written between 1150 and 1500. Until the advent of Modern Dutch after 1500 or c. 1550, there was no overarching standard language, but all dialects were mutually intelligible. During that period, a rich Medieval Dutch literature developed, which had not yet existed during Old Dutch. The various literary works of the time are often very readable for speakers of Modern Dutch since Dutch is a rather conservative language. Phonology Differences with Old Dutch Several phonological changes occurred leading up to the Middle Dutch period. * Earlier Old Dutch , , merge into already in Old Dutch. * Voiceless fricatives become voiced syllable-initially: > , > (merging with from Proto-Germanic ), > .

Ram Bow
A ram was a weapon fitted to varied types of ships, dating back to antiquity. The weapon comprised an underwater prolongation of the bow of the ship to form an armoured beak, usually between 2 and 4 meters (6–12 ft) in length. This would be driven into the hull of an enemy ship to puncture, sink or disable it. Ancient rams It was possibly developed in late Bronze age Egypt, but it only became widely used in later Iron age Mediterranean galleys. The ram was a naval weapon in the Greek/Roman antiquity and was used in such naval battles as Salamis and Actium. Naval warfare in the Mediterranean rarely used sails, and the use of rams specifically required oarsmen rather than sails in order to maneuver with accuracy and speed, and particularly to reverse the movement of a ramming ship to disentangle it from its sinking victim, lest it be pulled down when its victim sank. The Athenians were especially known for their ''diekplous'' and '' periplous'' tactics that disabled enemy ships ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Inverted Bow
In ship design, an inverted bow (occasionally also referred to as ''reverse bow'') is a ship's or large boat's bow whose farthest forward point is not at the top. The result may somewhat resemble a submarine's bow. Inverted bows maximize the length of waterline and hence the hull speed, and have often better hydrodynamic drag than ordinary bows. On the other hand, they have very little reserve buoyancy and tend to dive under waves instead of piercing or going over them. Inverted bows were popular on battleships and large cruisers in the early 20th century. They fell out of favour, as they were very wet at high speeds and in heavy seas, but have made a comeback on modern ship design. Examples Motor Yacht "A" The 390 ft luxury motor yacht M/Y "A" has an inverted bow, along with a tumblehome hull design. Ulstein X-Bow The Ulstein X-Bow (or just X-BOW) is an inverted ship's bow designed by Ulstein Group to improve handling in rough seas, and to lower fuel consumption ...
