Charrua (nautical)
''Charrua'' is a Portuguese nautical expression of the Age of Sail, initially used to designate the use of a frigate or a ship of the line owned by the State as a transport ship, reducing armament and complement, like the French nautical expression ''en flûte''. Details The ''charrua'' had large decks and big space for accommodation, and in sail terms it was not different from the ship of the line, having three masts, and also a large hold. The ''charrua'' was intended for the transport of troops, food, ammunition, etc. In the first half of the 19th century, the expression passed to designate any type of ship used as a passenger ship.

Age Of Sail
The Age of Sail is a period that lasted at the latest from the mid-16th (or mid- 15th) to the mid- 19th centuries, in which the dominance of sailing ships in global trade and warfare culminated, particularly marked by the introduction of naval artillery, and ultimately reached its highest extent at the advent of the analogue Age of Steam. Enabled by the advances of the related Age of Navigation, it is identified as a distinctive element of the early modern period and the Age of Discovery. Especially in context of the latter, it refers to a more particular Eurocentric Age of Sail, while generally the Age of Sail is the culminating period of a long intercontinental history of sailing. Periodization Like most periodic eras, the definition is inexact but instead serves as a general description. The term is used differently for warships and merchant vessels. Sailing ships are an ancient technology, making far-reaching trade like the ancient spice trade possible. With the M ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Frigate
A frigate () is a type of warship. In different eras, the roles and capabilities of ships classified as frigates have varied somewhat. The name frigate in the 17th to early 18th centuries was given to any full-rigged ship built for speed and maneuverability, intended to be used in scouting, escort and patrol roles. The term was applied loosely to ships varying greatly in design. In the second quarter of the 18th century, the 'true frigate' was developed in France. This type of vessel was characterised by possessing only one armed deck, with an unarmed deck below it used for berthing the crew. Late in the 19th century (British and French prototypes were constructed in 1858), armoured frigates were developed as powerful ironclad warships, the term frigate was used because of their single gun deck. Later developments in ironclad ships rendered the frigate designation obsolete and the term fell out of favour. During the Second World War the name 'frigate' was reintroduced to des ...

Ship Of The Line
A ship of the line was a type of naval warship constructed during the Age of Sail from the 17th century to the mid-19th century. The ship of the line was designed for the naval tactic known as the line of battle, which depended on the two columns of opposing warships maneuvering to volley fire with the cannons along their broadsides. In conflicts where opposing ships were both able to fire from their broadsides, the opponent with more cannons firingand therefore more firepowertypically had an advantage. Since these engagements were almost invariably won by the heaviest ships carrying more of the most powerful guns, the natural progression was to build sailing vessels that were the largest and most powerful of their time. From the end of the 1840s, the introduction of steam power brought less dependence on the wind in battle and led to the construction of screw-driven wooden-hulled ships of the line; a number of purely sail-powered ships were converted to this propulsion mech ...

State (polity)
A state is a centralized political organization that imposes and enforces rules over a population within a territory. There is no undisputed definition of a state. One widely used definition comes from the German sociologist Max Weber: a "state" is a polity that maintains a monopoly on the legitimate use of violence, although other definitions are not uncommon.Cudworth et al., 2007: p. 95Salmon, 2008p. 54 Absence of a state does not preclude the existence of a society, such as stateless societies like the Haudenosaunee Confederacy that "do not have either purely or even primarily political institutions or roles". The level of governance of a state, government being considered to form the fundamental apparatus of contemporary states, is used to determine whether it has failed. In a federal union, the term "state" is sometimes used to refer to the federated polities that make up the federation. (Other terms that are used in such federal systems may include “province”, ...

Maritime Transport
Maritime transport (or ocean transport) and hydraulic effluvial transport, or more generally waterborne transport, is the transport of people (passengers) or goods (cargo) via waterways. Freight transport by sea has been widely used throughout recorded history. The advent of aviation has diminished the importance of sea travel for passengers, though it is still popular for short trips and pleasure cruises. Transport by water is cheaper than transport by air, despite fluctuating exchange rates and a fee placed on top of freighting charges for carrier companies known as the currency adjustment factor. Maritime transport accounts for roughly 80% of international trade, according to UNCTAD The United Nations Conference on Trade and Development (UNCTAD) is an intergovernmental organization within the United Nations Secretariat that promotes the interests of developing countries in world trade. It was established in 1964 by the ... in 2020. Maritime transport can be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
En Flûte
''En flûte'' (French: "as a fluyt") is a French naval expression of the Age of Sail to designate the use of a warship as a transport with reduced armament.Willaumez, p. 294 Some warships, ships of the line or frigates, were occasionally used with limited artillery, by reducing the number and calibre of their guns. Since ships have a limited amount of cargo space, they may be armed ''en flûte'' to make room for other cargo, such as troops and ammunition. That reduces the ship's ability to defend herself if attacked. The term emerged from the French name for a type of ship – the cargo-carrying ''flûte'' used extensively as a mercantile ship or as a naval auxiliary vessel. In turn this derived from the Dutch name ''fluyt'', probably the most common type of cargo-carrier during the seventeenth century – when in English usage it was commonly rendered as a flyboat. This tactic was most relevant in the Age of Sail, when gun decks took up most of the space on a warship above the w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Academia De Marinha
The ''Academia de Marinha'' (Portuguese for "Navy Academy" or "Marine Academy"), MembIH is the cultural agency of the Portuguese Navy under the Chief of Naval Staff. Its purpose is to promote and to publish artistic, literary, historical, and scientific studies relating to the sea and maritime activities. Its offices are located in Lisbon at the Naval Headquarters, Rua do Arsenal. History This agency of the Portuguese Navy developed from the Maritime History Studies group (''Grupo de Estudos de História Marítima''), established in 1969 by the vice-admirals Sarmento Rodrigues and Teixeira da Mota. In the following year, it was renamed the Center for Naval Studies (''Centro de Estudos de Marinha''). In December 1978, its role was widened into a broader cultural agency and renamed the ''Academia de Marinha'' (Portaria nº 769). Motto The motto of the ''Academia de Marinha'' is a verse from Os Lusíadas ''Os Lusíadas'' (), usually translated as ''The Lusiads'', is a Portugue ...

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 ...

Sail
A sail is a tensile structure—which is made from fabric or other membrane materials—that uses wind power to propel sailing craft, including sailing ships, sailboats, windsurfers, ice boats, and even sail-powered land vehicles. Sails may be made from a combination of woven materials—including canvas or polyester cloth, laminated membranes or bonded filaments—usually in a three- or four-sided shape. A sail provides propulsive force via a combination of lift and drag, depending on its angle of attack—its angle with respect to the apparent wind. Apparent wind is the air velocity experienced on the moving craft and is the combined effect of the true wind velocity with the velocity of the sailing craft. Angle of attack is often constrained by the sailing craft's orientation to the wind or point of sail. On points of sail where it is possible to align the leading edge of the sail with the apparent wind, the sail may act as an airfoil, generating propulsive force as air p ...

Mast (sailing)
The mast of a sailing vessel is a tall spar, or arrangement of spars, erected more or less vertically on the centre-line of a ship or boat. Its purposes include carrying sails, spars, and derricks, and giving necessary height to a navigation light, look-out position, signal yard, control position, radio aerial or signal lamp. Large ships have several masts, with the size and configuration depending on the style of ship. Nearly all sailing masts are guyed. Until the mid-19th century, all vessels' masts were made of wood formed from a single or several pieces of timber which typically consisted of the trunk of a conifer tree. From the 16th century, vessels were often built of a size requiring masts taller and thicker than could be made from single tree trunks. On these larger vessels, to achieve the required height, the masts were built from up to four sections (also called masts). From lowest to highest, these were called: lower, top, topgallant, and royal masts. Giving the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hold (compartment)
120px, View of the hold of a container ship A ship's hold or cargo hold is a space for carrying cargo in the ship's compartment. Description Cargo in holds may be either packaged in crates, bales, etc., or unpackaged (bulk cargo). Access to holds is by a large hatch at the top. Ships have had holds for centuries; an alternative way to carry cargo is in standardized shipping containers, which may be loaded into appropriate holds or carried on deck. Holds in older ships were below the orlop deck, the lower part of the interior of a ship's hull, especially when considered as storage space, as for cargo. In later merchant vessels it extended up through the decks to the underside of the weather deck. Some ships have built in cranes and can load and unload their own cargo. Other ships must have dock side cranes or gantry cranes to load and unload. Cargo hatch A cargo hatch or deck hatch or hatchway is type of door used on ships and boats to cover the opening to the cargo hold or ...

Passenger Ship
A passenger ship is a merchant ship whose primary function is to carry passengers on the sea. The category does not include cargo vessels which have accommodations for limited numbers of passengers, such as the ubiquitous twelve-passenger freighters once common on the seas in which the transport of passengers is secondary to the carriage of freight. The type does however include many classes of ships designed to transport substantial numbers of passengers as well as freight. Indeed, until recently virtually all ocean liners were able to transport mail, package freight and express, and other cargo in addition to passenger luggage, and were equipped with cargo holds and derricks, kingposts, or other cargo-handling gear for that purpose. Only in more recent ocean liners and in virtually all cruise ships has this cargo capacity been eliminated. While typically passenger ships are part of the merchant marine, passenger ships have also been used as troopships and often are commissio ...
