Vettor Pisani (corvette)
''Vettor Pisani'' was a screw corvette of the Italian (Royal Navy) built in the late 1860s and early 1870s. The ship left Italy in 1882 for a three-year voyage round the world. Design The design for ''Vettor Pisani'' was prepared by the naval engineer Giuseppe Micheli. ''Vettor Pisani'' was long between perpendiculars, and she had a beam of and an average draft of . She displaced . She had a crew of 226. Her propulsion system consisted of a single marine steam engine that drove a single screw propeller. Steam was supplied by a pair of coal-fired fire-tube boilers that were manufactured by the firm Guppy of Naples. ''Vettor Pisani'' could steam at a top speed of from . To supplement the steam engines, she was fitted with a full ship rig. The main battery for ''Vettor Pisani'' consisted of six muzzle-loading guns, three guns per broadside. For close-range defense against torpedo boats, she initially carried a secondary battery of two guns, two guns, and two ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Regia Marina
The ''Regia Marina'' (; ) was the navy of the Kingdom of Italy (''Regno d'Italia'') from 1861 to 1946. In 1946, with the Italian constitutional referendum, 1946, birth of the Italian Republic (''Repubblica Italiana''), the ''Regia Marina'' changed its name to ''Marina Militare'' ("Military Navy"). Origins The ''Regia Marina'' was established on 17 March 1861 following the proclamation of the formation of the Kingdom of Italy (1861–1946), Kingdom of Italy. Just as the Kingdom was a unification of various states in the Italian Peninsula, Italian peninsula, so the ''Regia Marina'' was formed from the navies of those states, though the main constituents were the Real Marina (Kingdom of the Two Sicilies), navies of the former kingdoms of Kingdom of Sardinia, Sardinia and Kingdom of Naples, Naples. The new Navy inherited a substantial number of ships, both sail- and steam-powered, and the long naval traditions of its constituents, especially those of Sardinia and Naples, but also ...

Torpedo Boat
A torpedo boat is a relatively small and fast naval ship designed to carry torpedoes into battle. The first designs were steam-powered craft dedicated to ramming enemy ships with explosive spar torpedoes. Later evolutions launched variants of self-propelled Whitehead torpedoes. These were inshore craft created to counter both the threat of battleships and other slow and heavily armed ships by using speed, agility, and powerful torpedoes, and the overwhelming expense of building a like number of capital ships to counter an enemy's. A swarm of expendable torpedo boats attacking en masse could overwhelm a larger ship's ability to fight them off using its large but cumbersome guns. A fleet of torpedo boats could pose a similar threat to an adversary's capital ships, albeit only in the coastal areas to which their small size and limited fuel load restricted them. The introduction of fast torpedo boats in the late 19th century was a serious concern to the era's naval strategists, i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chonos Archipelago
The Chonos Archipelago is a series of low, mountainous, elongated islands with deep bays, traces of a submerged Chilean Coast Range. Most of the islands are forested with little or no human settlement. The deep Moraleda Channel separates the islands of the Chonos Archipelago from the mainland of Chile and from Magdalena Island. The largest islands are Melchor Island, Benjamin Island, Traiguen Island, Riveros Island, Cuptana Island, James Island, Victoria Island, Simpson Island, Level Island, Luz Island. Far out in the Pacific is Guamblin Island with the Isla Guamblin National Park. The National park comprises about 106 km². Blue whales can often be seen here. Some groups of islands are grouped into minor archipelagoes such as the Guaitecas Archipelago. The Guaitecas Archipelago has its own municipality and possesses the only settlement in the archipelago, Melinka. All islands are part of the Aisén Region. Chonos Archipelago was mapped in the 18th and 19th centurie ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anton Dohrn
Felix Anton Dohrn FRS FRSE (29 December 1840 – 26 September 1909) was a prominent German Darwinist and the founder and first director of the first zoological research station in the world, the Stazione Zoologica in Naples, Italy. He worked on embryology and examined vertebrate origins in terms of functional phylogeny and proposed a principle of succession of functions in 1875 on how one organ could become the basis for the evolution of another of an entirely different function. Family history Dohrn was born in Stettin (Szczecin), Prussian Province of Pomerania, into a wealthy middle-class family. His grandfather, Heinrich Dohrn, had been a wine and spice merchant, and had made the family fortune by trading in sugar. This wealth allowed Anton's father, Carl August, to devote himself to his various hobbies; travelling, folk music and insects. Anton, the youngest son, read zoology and medicine at various German universities (Königsberg, Bonn, Jena and Berlin). His br ...

Stazione Zoologica
The Stazione Zoologica Anton Dohrn is a research institute in Naples, Italy, devoted to basic research in biology. Research is largely interdisciplinary involving the fields of evolution, biochemistry, molecular biology, neurobiology, cell biology, biological oceanography, marine botany, molecular plant biology, benthic ecology, and ecophysiology. Founded in 1872 as a private concern by Anton Dohrn, in 1982 the Stazione Zoologica came under the supervision and control of the Ministero dell'Università e della Ricerca Scientifica e Tecnologica (Ministry of Universities and Scientific and Technological Research) as a National Institute. History The idea Dohrn's idea was to establish an international scientific community provided with laboratory space, equipment, research material and a library. This was supported and funded by the German Empire, German Government, Thomas Henry Huxley, Charles Darwin, Francis Maitland Balfour, Francis Balfour and Charles Lyell among others. Dohrn ...

He then participated in an educational cruise for officer candidates to Sout ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hydrographic Survey
Hydrographic survey is the science of measurement and description of features which affect maritime navigation, marine construction, dredging, offshore oil exploration/offshore oil drilling and related activities. Strong emphasis is placed on soundings, shorelines, tides, currents, seabed and submerged obstructions that relate to the previously mentioned activities. The term ''hydrography'' is used synonymously to describe ''maritime cartography'', which in the final stages of the hydrographic process uses the raw data collected through hydrographic survey into information usable by the end user. Hydrography is collected under rules which vary depending on the acceptance authority. Traditionally conducted by ships with a sounding line or echo sounding, surveys are increasingly conducted with the aid of aircraft and sophisticated electronic sensor systems in shallow waters. Organizations National and International Maritime Hydrography Hydrographic offices evolved from n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Fitting Out
Fitting out, or outfitting, is the process in shipbuilding that follows the float-out/launching of a vessel and precedes sea trials. It is the period when all the remaining construction of the ship is completed and readied for delivery to her owners. Since most of the fitting-out process is interior work, this stage can overlap with latter stages, such as the sea trials. Launching or floating After a vessel has been floated (in contemporary shipbuilding) or launched (in traditional shipbuilding), it is then towed out of its drydock and moored at a fitting-out berth. While still afloat, its construction is then continued. Depending on the type of vessel, fitting-out can last weeks or many months. Vessels with comparatively little space for human occupation, such as oil tankers, bulk carriers and container ships, can take the least time for fitting. Conversely, passenger ships take the longest. The process can include: * completion of the superstructure, * installation of the shi ...

Ship Launching
Ceremonial ship launching involves the performance of ceremonies associated with the process of transferring a vessel to the water. It is a nautical tradition in many cultures, dating back thousands of years, to accompany the physical process with ceremonies which have been observed as public celebration and a solemn blessing, usually but not always, in association with the launch itself. Ship launching imposes stresses on the ship not met during normal operation and, in addition to the size and weight of the vessel, represents a considerable engineering challenge as well as a public spectacle. The process also involves many traditions intended to invite good luck, such as christening by breaking a sacrificial bottle of champagne over the bow as the ship is named aloud and launched. Methods There are three principal methods of conveying a new ship from building site to water, only two of which are called "launching". The oldest, most familiar, and most widely used is th ...

Hull (watercraft)
A hull is the watertight body of a ship, boat, or flying boat. The hull may open at the top (such as a dinghy), or it may be fully or partially covered with a deck. Atop the deck may be a deckhouse and other superstructures, such as a funnel, derrick, or mast. The line where the hull meets the water surface is called the waterline. General features There is a wide variety of hull types that are chosen for suitability for different usages, the hull shape being dependent upon the needs of the design. Shapes range from a nearly perfect box in the case of scow barges to a needle-sharp surface of revolution in the case of a racing multihull sailboat. The shape is chosen to strike a balance between cost, hydrostatic considerations (accommodation, load carrying, and stability), hydrodynamics (speed, power requirements, and motion and behavior in a seaway) and special considerations for the ship's role, such as the rounded bow of an icebreaker or the flat bottom of a landing craft. ...
