Prow
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 ve ...

Longship
Longships were a type of specialised Scandinavian warships that have a long history in Scandinavia, with their existence being archaeologically proven and documented from at least the fourth century BC. Originally invented and used by the Norsemen (commonly known as the Vikings) for commerce, exploration, and warfare during the Viking Age, many of the longship's characteristics were adopted by other cultures, like Anglo-Saxons, and continued to influence shipbuilding for centuries. The longship's design evolved over many centuries, and continuing up until the sixth century with clinker-built ships like Nydam. The longship appeared in its complete form between the ninth and 13th centuries. The character and appearance of these ships have been reflected in Scandinavian boatbuilding traditions to the present day. The particular skills and methods employed in making longships are still used worldwide, often with modern adaptations. They were all made out of wood, with cloth sails ...

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] |
Glossary Of Nautical Terms
This glossary of nautical terms is an alphabetical listing of terms and expressions connected with ships, shipping, seamanship and navigation on water (mostly though not necessarily on the sea). Some remain current, while many date from the 17th to 19th centuries. The word nautical derives from the Latin ''nauticus'', from Greek ''nautikos'', from ''nautēs'': "sailor", from ''naus'': "ship". Further information on nautical terminology may also be found at Nautical metaphors in English, and additional military terms are listed in the Multiservice tactical brevity code article. Terms used in other fields associated with bodies of water can be found at Glossary of fishery terms, Glossary of underwater diving terminology, Glossary of rowing terms, and Glossary of meteorology. This glossary is split into two articles: * terms starting with the letters A to L are at Glossary of nautical terms (A-L) * terms starting with the letters M to Z are at Glossary of nautical terms (M-Z). __NO ...

Dutch Barge
A Dutch barge is a traditional flat-bottomed shoal-draught barge, originally used to carry cargo in the shallow ''Zuyder Zee'' and the waterways of Netherlands. There are very many types of Dutch barge, with characteristics determined by regional conditions and traditions. Originally, Dutch barges were sailing craft with wooden hulls. Today, while few wooden examples remain, there are many steel barges that are 100 years old or more. Although most Dutch barges have been converted to motor-propulsion, ''schuyt'' sailing contests are still held on the IJsselmeer and on the Wadden Sea (Waddenzee). Dutch barges have become popular live-aboard leisure craft, and brand-new "Dutch-style" examples continue to be built. The Dutch barge A typical traditional Dutch barge would have gaff rig, a bluff bow and stern, a pair of leeboards and a large rudder. The leeboards and rudder would be raised by an arrangement of blocks and tackles. Schuyts engaged in eel fishing were said to have begun ...

Clinker (boat Building)
Clinker built (also known as lapstrake) is a method of boat building where the edges of hull planks overlap each other. Where necessary in larger craft, shorter planks can be joined end to end, creating a longer strake or hull plank. The technique originated in Scandinavia, and was successfully used by the Anglo-Saxons, Frisians, Scandinavians, typically in the vessels known as cogs employed by the Hanseatic League. Carvel construction, where plank edges are butted smoothly, seam to seam, supplanted clinker construction in large vessels as the demand for capacity surpassed the limits of clinker construction. (See Comparison between clinker and carvel below.). Examples of clinker-built boats that are directly descended from those of the early medieval period are seen in the traditional round-bottomed Thames skiffs, and the larger (originally) cargo-carrying Norfolk wherries of England. Etymology From ''clinch'', or ''clench'', a common Germanic word, meaning “to fasten ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Aberdeen Bow
''Scottish Maid'' was a Scottish packet boat, a two-masted wooden schooner, built at Alexander Hall and Sons' boatyard in 1839 for the Aberdeen Line. She has been described as the first clipper vessel to be built in Britain. Her design of sharp, forward- raked bow, later called the "clipper bow" or Aberdeen bow, pioneered a succession of larger clipper ships with many also built in Aberdeen on Scotland's northeast coast. ''Scottish Maid'' was designed to take advantage of a deficiency in Britain's tonnage laws of 1836 so that her officially measured tonnage, and hence tax payable, was low compared with her load carrying capacity. As her designers anticipated, her shape of hull produced a fast vessel and to optimise this her bow (pointed front) was given an innovative shape to cut through the water cleanly – a profile that turned out to be particularly successful. The extreme clipper ships later in the 19th century had substantially larger hulls though they were somewhat simil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ship
A ship is a large watercraft that travels the world's oceans and other sufficiently deep waterways, carrying cargo or passengers, or in support of specialized missions, such as defense, research, and fishing. Ships are generally distinguished from boats, based on size, shape, load capacity, and purpose. Ships have supported exploration, trade, warfare, migration, colonization, and science. After the 15th century, new crops that had come from and to the Americas via the European seafarers significantly contributed to world population growth. Ship transport is responsible for the largest portion of world commerce. The word ''ship'' has meant, depending on the era and the context, either just a large vessel or specifically a ship-rigged sailing ship with three or more masts, each of which is square-rigged. As of 2016, there were more than 49,000 merchant ships, totaling almost 1.8 billion dead weight tons. Of these 28% were oil tankers, 43% were bulk carriers, and ...

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] |
