HMS Penguin (1876)
HMS ''Penguin'' was an sloop. Launched in 1876, ''Penguin'' was operated by the Royal Navy from 1877 to 1881, then from 1886 to 1889. After being converted to a survey vessel, ''Penguin'' was recommissioned in 1890, and operated until 1908, when she was demasted and transferred to the Australian Commonwealth Naval Forces for use as a depot and training ship in Sydney Harbour. After this force became the Royal Australian Navy, the sloop was commissioned as HMAS ''Penguin'' in 1913. ''Penguin'' remained in naval service until 1924, when she was sold off and converted into a floating crane. The vessel survived until 1960, when she was broken up and burnt. Design and construction ''Penguin'' was an ''Osprey''-class sloop-of-war, with a composite hull design. The ship had a displacement of 1,130 tons, was long, had a beam of , and a draught of .Winfield, pp.291–292 An R & W Hawthorn two-cylinder horizontal returning-rod steam engine fed by three cylindrical boilers provided ...

Composite Hull
The technique of composite ship construction ( wooden planking over a wrought iron frame) emerged in the mid-19th century as the final stage in the evolution of fast commercial sailing ships. Construction of wrought iron hulled vessels had begun in the 1820s and was a mature technology by the time of the launch of the SS ''Great Britain'' in 1843. However, iron hulls could not be sheathed with copper alloy (due to bimetallic corrosion) and so would become festooned with drag-inducing weed during long voyages in the tropics. The wooden planking of a composite ship allowed the copper sheathing essential for fast ocean crossings under sail while the iron frame made the ship relatively immune from hogging and sagging, and took up less interior space than wooden framing. The brief reign of composite clippers as the fastest mode of transport between Europe and Asia was brought to a close by the opening of the Suez Canal in 1869 and ongoing improvement in the performance of ste ...

Kermadec Trench
The Kermadec Trench is a linear ocean trench in the south Pacific Ocean. It stretches about from the Louisville Seamount Chain in the north (26°S) to the Hikurangi Plateau in the south (37°S), north-east of New Zealand's North Island. Together with the Tonga Trench to the north, it forms the -long, near-linear Kermadec-Tonga subduction system, which began to evolve in the Eocene when the Pacific Plate started to subduct beneath the Australian Plate. Convergence rates along this subduction system are among the fastest on Earth, /yr in the north and /yr in the south. Geology The Kermadec Trench is one of Earth's deepest oceanic trenches, reaching a depth of . Formed by the subduction of the Pacific Plate under the Indo-Australian Plate, it runs parallel with and to the east of the Kermadec Ridge and island arc. The Tonga Trench marks the continuation of subduction to the north. The Kermadec Trench has a southern continuation in the turbidite-filled Hikurangi Trough, but a s ...

Henry Boyle Townshend Somerville
Vice-Admiral Henry Boyle Townshend Somerville (7 September 1863 – 24 March 1936) was an Irish naval officer and author who served in the Royal Navy. He was also an author author who wrote on maritime topics as well as ethnography and archaeology. Somerville was murdered by the Irish Republican Army in 1936. Early life and naval career Boyle Somerville was born at Castletownshend, Co. Cork. His father was Thomas Henry Somerville and his mother was Adelaide Eliza Coghill. Somerville joined the Royal Navy as a cadet in 1877. His first service was in South America in 1880, and then in the Anglo-Egyptian War in 1882. He then spent four years on the China Station. He trained as a Hydrographic Surveyor, choosing this branch of the Navy because promotion prospects were good, and because it offered opportunities for a much freer existence than the "intolerable uniformity" that he saw as typical of much Navy life. As a lieutenant, Somerville worked on the surveys of the Queensland ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Great Barrier Reef
The Great Barrier Reef is the world's largest coral reef system composed of over 2,900 individual reefs and 900 islands stretching for over over an area of approximately . The reef is located in the Coral Sea, off the coast of Queensland, Australia, separated from the coast by a channel 100 miles wide in places and over 200 feet deep. The Great Barrier Reef can be seen from outer space and is the world's biggest single structure made by living organisms. This reef structure is composed of and built by billions of tiny organisms, known as coral polyps. It supports a wide diversity of life and was selected as a World Heritage Site in 1981. CNN labelled it one of the seven natural wonders of the world in 1997. Australian World Heritage places included it in its list in 2007. The Queensland National Trust named it a state icon of Queensland in 2006. A large part of the reef is protected by the Great Barrier Reef Marine Park, which helps to limit the impact of human use, such a ...

New Zealand
New Zealand ( mi, Aotearoa ) is an island country in the southwestern Pacific Ocean. It consists of two main landmasses—the North Island () and the South Island ()—and over 700 smaller islands. It is the sixth-largest island country by area, covering . New Zealand is about east of Australia across the Tasman Sea and south of the islands of New Caledonia, Fiji, and Tonga. The country's varied topography and sharp mountain peaks, including the Southern Alps, owe much to tectonic uplift and volcanic eruptions. New Zealand's capital city is Wellington, and its most populous city is Auckland. The islands of New Zealand were the last large habitable land to be settled by humans. Between about 1280 and 1350, Polynesians began to settle in the islands and then developed a distinctive Māori culture. In 1642, the Dutch explorer Abel Tasman became the first European to sight and record New Zealand. In 1840, representatives of the United Kingdom and Māori chiefs ...

Australia Station
The Australia Station was the British, and later Australian, naval command responsible for the waters around the Australian continent.Dennis et al. 2008, p.53. Australia Station was under the command of the Commander-in-Chief, Australia Station, whose rank varied over time. History In the years following the establishment of the British colony of New South Wales in 1788, Royal Navy ships stationed in Australian waters formed part of the East Indies Squadron and came under the command of the East Indies Station. From the 1820s, a ship was sent annually to New South Wales, and occasionally to New Zealand. In 1848, an Australian Division of the East Indies Station was established, and in 1859 the British Admiralty established an independent command, the Australia Station, under the command of a commodore who was assigned as Commander-in-Chief, Australia Station. The Australian Squadron was created to which British naval ships serving on the Australia Station were assigned. The cha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Zanzibar Town
Stonetown of Zanzibar ( ar, مدينة زنجبار الحجرية), also known as Mji Mkongwe ( Swahili for "old town"), is the old part of Zanzibar City, the main city of Zanzibar, in Tanzania. The newer portion of the city is known as Ng'ambo, Swahili for 'the other side'. Stone Town is located on the western coast of Unguja, the main island of the Zanzibar Archipelago. Former capital of the Zanzibar Sultanate, and flourishing centre of the spice trade as well as the slave trade in the 19th century, it retained its importance as the main city of Zanzibar during the period of the British protectorate. When Tanganyika and Zanzibar joined each other to form the United Republic of Tanzania, Zanzibar kept a semi-autonomous status, with Stone Town as its local government seat. Stone Town is a city of prominent historical and artistic importance in East Africa. Its architecture, mostly dating back to the 19th century, reflects the diverse influences underlying the Swahili culture, ...

East Indies Station
The East Indies Station was a formation and command of the British Royal Navy. Created in 1744 by the Admiralty, it was under the command of the Commander-in-Chief, East Indies. Even in official documents, the term ''East Indies Station'' was often used. In 1941 the ships of the China Squadron and East Indies Squadron were merged to form the Eastern Fleet under the control of the Commander-in-Chief, Eastern Fleet. The China Station then ceased as a separate command. The East Indies Station was disbanded in 1958. It encompassed Royal Navy Dockyards and bases in East Africa, Middle East, India and Ceylon, and other ships not attached to other fleets. For many years under rear admirals, from the 1930s the Commander-in-Chief was often an Admiral or a Vice-Admiral. History The East Indies Station was established as a Royal Navy command in 1744. From 1831 to 1865, the East Indies and the China Station were a single command known as the East Indies and China Station. The East Ind ...

Pacific Station
The Pacific Station was created in 1837 as one of the geographical military formations into which the Royal Navy divided its worldwide responsibilities. The South America Station was split into the Pacific Station and the South East Coast of America Station. History The British Pacific Squadron was established in 1813 to support British interests along the eastern shores of the Pacific Ocean at Valparaíso, Chile. In 1837, when the South America station was split, this responsibility was passed to the Commander-in-Chief, Pacific. In 1843, Lord George Paulet, George Paulet, captain of , took her out from Valparaíso to Honolulu to demand the islands of the Kingdom of Hawaii for Britain. King Kamehameha III capitulated and signed the islands over to Paulet. In the summer of that year, Rear-Admiral Richard Darton Thomas set out from Valparaíso in to rein Paulet in. On 31 July 1843, Thomas assured the King that the occupation was over and that there was no Paulet Affair (1843) ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
RML 7 Inch 90 Cwt Gun
The RML 7-inch guns were various designs of medium-sized rifled muzzle-loading guns used to arm small to medium-sized British warships in the late 19th century, and some were used ashore for coast defence. Design and history These guns were the first to incorporate the new "Woolwich" rifling system, a modification of the French system, of from 3 – 9 broad shallow grooves after Britain abandoned the Armstrong "shunt" rifling system in May 1865 : "...M.L. 7-inch guns in course of manufacture were rifled on this principle, upon which all of our heavy pieces since have been rifled. The 7-inch referred to, and introduced into the service in 1865, were the first of the so-called Woolwich guns, which then meant "''wrought iron M.L. guns built up on Sir W. Armstrong's principle, improved upon by hooking the coils over one another, and having solid ended steel barrels, rifled on the system shown above, for studded projectiles''". All versions were constructed of a steel A tube surround ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Barque
A barque, barc, or bark is a type of sailing ship, sailing vessel with three or more mast (sailing), masts having the fore- and mainmasts Square rig, rigged square and only the mizzen (the aftmost mast) Fore-and-aft rig, rigged fore and aft. Sometimes, the mizzen is only partly fore-and-aft rigged, bearing a square-rigged sail above. Etymology The word "barque" entered English via the French term, which in turn came from the Latin language, Latin ''barca'' by way of Occitan language, Occitan, Catalan language, Catalan, Spanish, or Italian. The Latin ''barca'' may stem from Celtic language, Celtic ''barc'' (per Rudolf Thurneysen, Thurneysen) or Greek ''baris'' (per Friedrich Christian Diez, Diez), a term for an Egyptian boat. The ''Oxford English Dictionary'', however, considers the latter improbable. The word ''barc'' appears to have come from Celtic languages. The form adopted by English, perhaps from Irish language, Irish, was "bark", while that adopted by Latin as ''barca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
