Italian Cruiser Partenope
''Partenope'' was a torpedo cruiser built for the Italian ''Regia Marina'' (Royal Navy) in the 1880s, the lead ship of her class, which included seven other vessels. The ship was built by the ''Regio Cantiere di Castellammare di Stabia''; she was laid down in June 1888, was launched in December 1889, and was completed in September 1890. Her main armament were her five torpedo tubes, which were supported by a battery of ten small-caliber guns. ''Partenope'' spent most of her career in the main Italian fleet, where she was primarily occupied with training exercises. In 1906–08, she was converted into a minelayer, losing her torpedo tubes. During the Italo-Turkish War of 1911–12, she provided gunfire support to Italian forces in Libya. She was used to lay a series of minefields in the Adriatic Sea after Italy entered World War I in 1915. In March 1918, ''Partenope'' was torpedoed and sunk by the German submarine off Bizerte.

Kingdom Of Italy
The Kingdom of Italy ( it, Regno d'Italia) was a state that existed from 1861, when Victor Emmanuel II of Sardinia was proclaimed King of Italy, until 1946, when civil discontent led to an institutional referendum to abandon the monarchy and form the modern Italian Republic. The state resulted from a decades-long process, the '' Risorgimento'', of consolidating the different states of the Italian Peninsula into a single state. That process was influenced by the Savoy-led Kingdom of Sardinia, which can be considered Italy's legal predecessor state. Italy declared war on Austria in alliance with Prussia in 1866 and received the region of Veneto following their victory. Italian troops entered Rome in 1870, ending more than one thousand years of Papal temporal power. Italy entered into a Triple Alliance with the German Empire and the Austro-Hungarian Empire in 1882, following strong disagreements with France about their respective colonial expansions.

Adriatic Sea
The Adriatic Sea () is a body of water separating the Italian Peninsula from the Balkans, Balkan Peninsula. The Adriatic is the northernmost arm of the Mediterranean Sea, extending from the Strait of Otranto (where it connects to the Ionian Sea) to the northwest and the Po Valley. The countries with coasts on the Adriatic are Albania, Bosnia and Herzegovina, Croatia, Italy, Montenegro, and Slovenia. The Adriatic contains more than 1,300 islands, mostly located along the Croatian part of its eastern coast. It is divided into three basins, the northern being the shallowest and the southern being the deepest, with a maximum depth of . The Otranto Sill, an underwater ridge, is located at the border between the Adriatic and Ionian Seas. The prevailing currents flow counterclockwise from the Strait of Otranto, along the eastern coast and back to the strait along the western (Italian) coast. Tidal movements in the Adriatic are slight, although acqua alta, larger amplitudes are known to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Forecastle
The forecastle ( ; contracted as fo'c'sle or fo'c's'le) is the upper deck of a sailing ship forward of the foremast, or, historically, the forward part of a ship with the sailors' living quarters. Related to the latter meaning is the phrase " before the mast" which denotes anything related to ordinary sailors, as opposed to a ship's officers. History and design In medieval shipbuilding, a ship of war was usually equipped with a tall, multi-deck castle-like structure in the bow of the ship. It served as a platform for archers to shoot down on enemy ships, or as a defensive stronghold if the ship were boarded. A similar but usually much larger structure, called the aftcastle, was at the aft end of the ship, often stretching all the way from the main mast to the stern. Having such tall upper works on the ship was detrimental to sailing performance. As cannons were introduced and gunfire replaced boarding as the primary means of naval combat during the 16th century, the medieval ...

Normal Displacement
The displacement or displacement tonnage of a ship is its weight. As the term indicates, it is measured indirectly, using Archimedes' principle, by first calculating the volume of water displaced by the ship, then converting that value into weight. Traditionally, various measurement rules have been in use, giving various measures in long tons. Today, tonnes are more commonly used. Ship displacement varies by a vessel's degree of load, from its empty weight as designed (known as "lightweight tonnage") to its maximum load. Numerous specific terms are used to describe varying levels of load and trim, detailed below. Ship displacement should not be confused with measurements of volume or capacity typically used for commercial vessels and measured by tonnage: net tonnage and gross tonnage. Calculation The process of determining a vessel's displacement begins with measuring its draft.George, 2005. p.5. This is accomplished by means of its "draft marks" (or "load lines"). A merch ...

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 a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Beam (nautical)
The beam of a ship is its width at its widest point. The maximum beam (BMAX) is the distance between planes passing through the outer extremities of the ship, beam of the hull (BH) only includes permanently fixed parts of the hull, and beam at waterline (BWL) is the maximum width where the hull intersects the surface of the water. Generally speaking, the wider the beam of a ship (or boat), the more initial stability it has, at the expense of secondary stability in the event of a capsize, where more energy is required to right the vessel from its inverted position. A ship that heels on her ''beam ends'' has her deck beams nearly vertical. Typical values Typical length-to-beam ratios ( aspect ratios) for small sailboats are from 2:1 (dinghies to trailerable sailboats around ) to 5:1 (racing sailboats over ). Large ships have widely varying beam ratios, some as large as 20:1. Rowing shells In watercraft, a racing shell (also referred to as just a ''fine boat'' (UK) or just ' ...

Length Overall
__NOTOC__ Length overall (LOA, o/a, o.a. or oa) is the maximum length of a vessel's hull measured parallel to the waterline. This length is important while docking the ship. It is the most commonly used way of expressing the size of a ship, and is also used for calculating the cost of a marina A marina (from Spanish , Portuguese and Italian : ''marina'', "coast" or "shore") is a dock or basin with moorings and supplies for yachts and small boats. A marina differs from a port in that a marina does not handle large passenger ships o ... berth (for example, £2.50 per metre LOA). LOA is usually measured on the hull alone. For sailing ships, this may ''exclude'' the bowsprit and other fittings added to the hull. This is how some racing boats and tall ships use the term LOA. However, other sources may include bowsprits in LOA. Confusingly, LOA has different meanings. "Sparred length", "Total length including bowsprit", "Mooring length" and "LOA including bowsprit" are oth ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ironclad Warship
An ironclad is a steam engine, steam-propelled warship protected by Wrought iron, iron or steel iron armor, armor plates, constructed from 1859 to the early 1890s. The ironclad was developed as a result of the vulnerability of wooden warships to explosive or incendiary shell (projectile), shells. The first ironclad battleship, , was launched by the French Navy in November 1859 - narrowly pre-empting the British Royal Navy. They were first used in warfare in 1862 during the American Civil War, when ironclads operated against wooden ships and, in a historic confrontation, against each other at the Battle of Hampton Roads in Virginia. Their performance demonstrated that the ironclad had replaced the unarmored ship of the line as the most powerful warship afloat. City-class ironclad, Ironclad gunboats became very successful in the American Civil War. Ironclads were designed for several uses, including as high seas battleships, long-range cruisers, and Littoral (military), coast ...

Torpedo
A modern torpedo is an underwater ranged weapon launched above or below the water surface, self-propelled towards a target, and with an explosive warhead designed to detonate either on contact with or in proximity to the target. Historically, such a device was called an automotive, automobile, locomotive, or fish torpedo; colloquially a ''fish''. The term ''torpedo'' originally applied to a variety of devices, most of which would today be called mines. From about 1900, ''torpedo'' has been used strictly to designate a self-propelled underwater explosive device. While the 19th-century battleship had evolved primarily with a view to engagements between armored warships with large-caliber guns, the invention and refinement of torpedoes from the 1860s onwards allowed small torpedo boats and other lighter surface vessels, submarines/submersibles, even improvised fishing boats or frogmen, and later light aircraft, to destroy large ships without the need of large guns, though ...

Jeune École
The ''Jeune École'' ("Young School") was a strategic naval concept developed during the 19th century. It advocated the use of small, heavily armed vessels to combat larger battleships, and the use of commerce raiders to cripple the trade of the rival nation. The idea was developed among French naval theorists: the French government had the second largest navy of the time, and the theorists desired to counteract the strength of the larger British Royal Navy. Small units against battleships One of the first proponents of the ''Jeune École'' was the artillery general Henri-Joseph Paixhans, who invented explosive shell guns for warships during the 1820s. He advocated the use of these powerful guns on numerous small steam warships that could destroy much larger battleships. Later, the French Navy developed the concept more elaborately as it experimented with torpedoes and torpedo boats. The French Navy became one of the strongest proponents of this combat system by the end of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
