Koff (ship Type)
A koff is a historical type of sailing vessel that was used for coastal shipping off Belgium, the Netherlands, and Germany in the 18th and 19th centuries. A typical koff had one and a half masts with a gaff rigged main sail and spanker and one or two square sails in the main top. The hull was plump with a flat bottom and a heavily rounded, raised bow and stern. Smaller koffs could be equipped with leeboards. Due to the shallow draught, koffs were especially suited for inshore shipping in shallow waters. The koff had been developed in the late 17th century in the Netherlands. Smaller than the fluyt, its rounded bow and stern provided however for more storage on board. This made it a popular type that saw increasing service. Koffs were often counted among the galiots by contemporary sources because the differences are very subtle: the galiot was considered more slender and therefore more elegant. On the koff, a deckhouse could be installed between the two masts which would pro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kofschip
The t kofschip (, ''the merchant-ship''), t fokschaap (the breeding sheep), also often referred to as kofschiptaxi or soft ketchup (among foreign language learners) rule is a mnemonic that determines the endings of a regular Dutch verb in the past indicative/subjunctive and the ending of the past participle. This rule should not be confused with the so-called T-rules (''t-regels''). Rule The rule goes as follows: For example: Because of the idiosyncrasies of Dutch spelling, some forms are spelled in unexpected ways. The past tense forms of ''proeven'' and ''blozen'' are written with ''f'' and ''s'', as Dutch spelling rules permit the letters ''v'' and ''z'' only at the beginning of a syllable; however the pronunciation remains and . Words may not end in a double consonant, so the past participles ''gerust'', ''geland'' and ''gered'' do not get an additional ''-d''. See Dutch orthography for more information. Because of regular final-obstruent devoicing, the past particip ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Germany
Germany,, officially the Federal Republic of Germany, is a country in Central Europe. It is the second most populous country in Europe after Russia, and the most populous member state of the European Union. Germany is situated between the Baltic and North seas to the north, and the Alps to the south; it covers an area of , with a population of almost 84 million within its 16 constituent states. Germany borders Denmark to the north, Poland and the Czech Republic to the east, Austria and Switzerland to the south, and France, Luxembourg, Belgium, and the Netherlands to the west. The nation's capital and most populous city is Berlin and its financial centre is Frankfurt; the largest urban area is the Ruhr. Various Germanic tribes have inhabited the northern parts of modern Germany since classical antiquity. A region named Germania was documented before AD 100. In 962, the Kingdom of Germany formed the bulk of the Holy Roman Empire. During the 16th ce ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gaff Rig
Gaff rig is a sailing rig (configuration of sails, mast and stays) in which the sail is four-cornered, fore-and-aft rigged, controlled at its peak and, usually, its entire head by a spar (pole) called the ''gaff''. Because of the size and shape of the sail, a gaff rig will have running backstays rather than permanent backstays. The gaff enables a fore and aft sail to be four sided, rather than triangular. A gaff rig typically carries 25 percent more sail than an equivalent Bermudian rig for a given hull design. A sail hoisted from a gaff is called a gaff-rigged (or, less commonly, gaff rigged or gaffrigged) sail. Description Gaff rig remains the most popular fore-aft rig for schooner and barquentine mainsails and other course sails, and spanker sails on a square rigged vessel are always gaff rigged. On other rigs, particularly the sloop, ketch and yawl, gaff rigged sails were once common but have now been largely replaced by the Bermuda rig sail, which, in addition to bei ...

Spanker (sail)
On a square rigged ship, the spanker is a gaff-rigged fore-and-aft sail set from and aft of the aftmost mast. Spankers are also called ''driver'', ''jigger'', and a ''pusher'' sail. On a schooner of four or more masts, the spanker is the sail on the mast nearest the stern. The spanker is a small sail, but as it is so far aft of the balance point of the hull, it has strong leverage: when sheeted in, the spanker is important in driving the boat to a new tack TACK is a group of archaea acronym for Thaumarchaeota (now Nitrososphaerota), Aigarchaeota, Crenarchaeota (now Thermoproteota), and Korarchaeota, the first groups discovered.

Square Rig
Square rig is a generic type of sail and rigging arrangement in which the primary driving sails are carried on horizontal spars which are perpendicular, or square, to the keel of the vessel and to the masts. These spars are called ''yards'' and their tips, outside the lifts, are called the ''yardarms.'' A ship mainly rigged so is called a square-rigger. The square rig is aerodynamically the most efficient running rig (i.e., sailing downwind), and stayed popular on ocean-going sailing ships until the end of the Age of Sail. The last commercial sailing ships, windjammers, were usually square-rigged four-masted barques. History The oldest archaeological evidence of use of a square-rig on a vessel is an image on a clay disk from Mesopotamia from 5000 BC. Single sail square rigs were used by the ancient Egyptians, the Phoenicians, the Greeks, the Romans, and the Celts. Later the Scandinavians, the Germanic peoples, and the Slavs adopted the single square-rigged sail, with it be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bow (ship)
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 ...

Stern
The stern is the back or aft-most part of a ship or boat, technically defined as the area built up over the sternpost, extending upwards from the counter rail to the taffrail. The stern lies opposite the bow, the foremost part of a ship. Originally, the term only referred to the aft port section of the ship, but eventually came to refer to the entire back of a vessel. The stern end of a ship is indicated with a white navigation light at night. Sterns on European and American wooden sailing ships began with two principal forms: the ''square'' or ''transom'' stern and the ''elliptical'', ''fantail'', or ''merchant'' stern, and were developed in that order. The hull sections of a sailing ship located before the stern were composed of a series of U-shaped rib-like frames set in a sloped or "cant" arrangement, with the last frame before the stern being called the ''fashion timber(s)'' or ''fashion piece(s)'', so called for "fashioning" the after part of the ship. This frame is d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Leeboard
A leeboard is a form of pivoting keel used by a sailboat largely and very often in lieu of a fixed keel. Typically mounted in pairs on each side of a hull, leeboards function much like a centreboard, allowing shallow-draft craft to ply waters fixed keel boats cannot. Only the leeward side leeboard is used at any time, as it submerges when the boat heels under the force of the wind. A disadvantage, where there is an inadequate fixed keel, is that they typically ship (bear) little ballast, which being on the far side delays the onset of unballasted craft's heeling, that is, to put up a good, constant resistance against the wind. The classical, archetypal definition of ballast is a low, central weight to optimise centre of mass, reduce turning moment and therefore resistance to the boat keeling over, however tends to be higher in self-righting vessels. Modern developments allow them to act as a speed-enhancing lifting foil. History Leeboards existed in China from at least the e ...

Draft (hull)
The draft or draught of a ship's hull is the vertical distance between the waterline and the bottom of the hull (keel). The draught of the vessel is the maximum depth of any part of the vessel, including appendages such as rudders, propellers and drop keels if deployed. Draft determines the minimum depth of water a ship or boat can safely navigate. The related term air draft is the maximum height of any part of the vessel above the water. The more heavily a vessel is loaded, the deeper it sinks into the water, and the greater its draft. After construction, the shipyard creates a table showing how much water the vessel displaces based on its draft and the density of the water (salt or fresh). The draft can also be used to determine the weight of cargo on board by calculating the total displacement of water, accounting for the content of the ship's bunkers, and using Archimedes' principle. The closely related term "trim" is defined as the difference between the forward and aft ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fluyt
A fluyt (archaic Dutch: ''fluijt'' "flute"; ) is a Dutch type of sailing vessel originally designed by the shipwrights of Hoorn as a dedicated cargo vessel. Originating in the Dutch Republic in the 16th century, the vessel was designed to facilitate transoceanic delivery with the maximum of space and crew efficiency. Unlike rivals, it was not built for conversion in wartime to a warship, so it was cheaper to build and carried twice the cargo, and could be handled by a smaller crew. Construction by specialized shipyards using new tools made it half the cost of rival ships. These factors combined to sharply lower the cost of transportation for Dutch merchants, giving them a major competitive advantage. The fluyt was a significant factor in the 17th-century rise of the Dutch seaborne empire. In 1670 the Dutch merchant marine totalled 568,000 tons of shipping—about half the European total. Ship design The standard fluyt design minimized or completely eliminated its armaments to max ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Galiot
A galiot, galliot or galiote, was a small galley boat propelled by sail or oars. There are three different types of naval galiots that sailed on different seas. A ''galiote'' was a type of French flat-bottom river boat or barge and also a flat-bottomed boat with a simple sail for transporting wine. Naval vessels * Mediterranean, (16th–17th centuries) : Historically, a galiot was a type of ship with oars, also known as a half-galley, then, from the 17th century forward, a ship with sails and oars. As used by the Barbary pirates against the Republic of Venice, a galiot had two masts and about 16 pairs of oars. Warships of the type typically carried between two and ten cannons of small caliber, and between 50 and 150 men. It was a Barbary galiot, captained by Barbarossa I, that captured two Papal vessels in 1504. * North Sea (17th–19th centuries) : A galiot was a type of Dutch or German merchant ship of 20 to 400 tons ( bm), similar to a ketch, with a rounded fore and aft like ...
