Arrow Class Gunvessel
The ''Arrow'' class comprised six second-class screw-driven vessels built as despatch vessels for the Royal Navy in 1854, mounting 6 guns. In 1856 they were redesignated as second-class gunvessels. Construction Design The Crimean War sparked a sudden need for shallow-draught, manoeuvrable vessels for inshore work in the Baltic and the Black Sea. The ''Arrow'' class of six wooden-hulled screw steamers were built during 1854 to a design by the Surveyor’s Department. Construction was undertaken at two commercial yards on the Thames, R & H Green at Blackwall Yard and C J Mare & Company, at Leamouth. Two further designs of Crimean War gunvessel were ordered during 1855, the ''Intrepid'' class and the ''Vigilant'' class, and in 1856 the six ''Arrow''-class despatch vessels were re-classed as second-class gunvessels. Propulsion A two-cylinder horizontal single expansion steam engine provided through a single screw. Sail plan All ''Arrow''-class gunvessels were barque-rigged. ...

Oswald Walters Brierly
Sir Oswald Walters Brierly (19 May 1817 – 14 December 1894), was an English marine painter from an old Cheshire family and he was born at Chester. Life He was the son of Thomas Brierly, a doctor and amateur artist, who belonged to an old Cheshire family, was born at Chester on 19 May 1817. After a general grounding in art at the academy of Henry Sass in Bloomsbury, he went to Plymouth to study naval architecture and rigging. He exhibited drawings of two men-of-war at Plymouth, and , at the Royal Academy in 1839. He then spent some time in the study of navigation, and in 1841 started on a voyage to Australia with his friend Benjamin Boyd in the latter's yacht ''Wanderer''. Boyd established himself in New South Wales as a merchant banker, pastoralist, shipowner, whaler and member of parliament. Brierly lived in southern New South Wales in a new settlement named Boydtown where he managed Boyd's whaling operations until 1848. Boyd even went so far as to have a house ...

Black Sea
The Black Sea is a marginal mediterranean sea of the Atlantic Ocean lying between Europe and Asia, east of the Balkans, south of the East European Plain, west of the Caucasus, and north of Anatolia. It is bounded by Bulgaria, Georgia, Romania, Russia, Turkey, and Ukraine. The Black Sea is supplied by major rivers, principally the Danube, Dnieper, and Don. Consequently, while six countries have a coastline on the sea, its drainage basin includes parts of 24 countries in Europe. The Black Sea covers (not including the Sea of Azov), has a maximum depth of , and a volume of . Most of its coasts ascend rapidly. These rises are the Pontic Mountains to the south, bar the southwest-facing peninsulas, the Caucasus Mountains to the east, and the Crimean Mountains to the mid-north. In the west, the coast is generally small floodplains below foothills such as the Strandzha; Cape Emine, a dwindling of the east end of the Balkan Mountains; and the Dobruja Plateau considerably farth ...

Gunboat Classes
A gunboat is a naval watercraft designed for the express purpose of carrying one or more guns to bombard coastal targets, as opposed to those military craft designed for naval warfare, or for ferrying troops or supplies. History Pre-steam era In the age of sail, a gunboat was usually a small undecked vessel carrying a single smoothbore cannon in the bow, or just two or three such cannons. A gunboat could carry one or two masts or be oar-powered only, but the single-masted version of about length was most typical. Some types of gunboats carried two cannons, or else mounted a number of swivel guns on the railings. The small gunboat had advantages: if it only carried a single cannon, the boat could manoeuvre in shallow or restricted areas – such as rivers or lakes – where larger ships could sail only with difficulty. The gun that such boats carried could be quite heavy; a 32-pounder for instance. As such boats were cheap and quick to build, naval forces favoured swarm ...

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] |
Propeller
A propeller (colloquially often called a screw if on a ship or an airscrew if on an aircraft) is a device with a rotating hub and radiating blades that are set at a pitch to form a helical spiral which, when rotated, exerts linear thrust upon a working fluid such as water or air. Propellers are used to pump fluid through a pipe or duct, or to create thrust to propel a boat through water or an aircraft through air. The blades are specially shaped so that their rotational motion through the fluid causes a pressure difference between the two surfaces of the blade by Bernoulli's principle which exerts force on the fluid. Most marine propellers are screw propellers with helical blades rotating on a propeller shaft (ship), propeller shaft with an approximately horizontal axis. History Early developments The principle employed in using a screw propeller is derived from sculling. In sculling, a single blade is moved through an arc, from side to side taking care to keep presenting the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vigilant Class Gunvessel
The ''Vigilant''-class gunvessel of the Royal Navy was an enlarged version of the ''Arrow''-class gunvessel of 1854. Both classes were designed for shallow-water operations in the Baltic and Black Seas during the Crimean War. Fourteen of the class were completed, but were ready too late to take part in that conflict. ''Cormorant'' was sunk in action at the Taku Forts, ''Osprey'' was wrecked on the coast of Africa in 1867 and the rest were all sold during the 1860s, with ''Sparrowhawk'' lasting until 1872. Design The class were designed as second-class despatch and gunvessels. They were intended to operate close inshore during the Crimean War The Crimean War, , was fought from October 1853 to February 1856 between Russia and an ultimately victorious alliance of the Ottoman Empire, France, the United Kingdom and Piedmont-Sardinia. Geopolitical causes of the war included the ... and were essentially enlarged versions of the ''Arrow''-class gunvessel, which has bee ...

Intrepid Class Gunvessel
''Intrepid''-class gunvessels were a class of six Royal Navy first-class wooden gunvessels built in 1855-56. They were rated as sloops from 1859 to 1862,Except ''Victor'', which remained a gunvessel throughout the period and were scrapped by 1865. ''Victor'' was sold to the Confederate States of America as the raider CSS ''Rappahannock'', but she was interned by the French at Calais and never fulfilled her intended function. Design and construction Designed in 1855, the ''Intrepid''-class gunvessels were intended to serve in the shallow waters of the Black and Baltic seas during the Crimean War.Winfield (2008) p. 218 They were built quickly, and of inferior wood, which explains their short lifespan of 10 years. Propulsion A two-cylinder horizontal single-expansion steam engine produced between and through a single screw, giving a speed of about . Twin funnels distinguished them from most other British classes of gunvessel. Sail plan The vessels of the class were designed ...

River Thames
The River Thames ( ), known alternatively in parts as the The Isis, River Isis, is a river that flows through southern England including London. At , it is the longest river entirely in England and the Longest rivers of the United Kingdom, second-longest in the United Kingdom, after the River Severn. The river rises at Thames Head in Gloucestershire, and flows into the North Sea near Tilbury, Essex and Gravesend, Kent, via the Thames Estuary. From the west it flows through Oxford (where it is sometimes called the Isis), Reading, Berkshire, Reading, Henley-on-Thames and Windsor, Berkshire, Windsor. The Thames also drains the whole of Greater London. In August 2022, the source of the river moved five miles to beyond Somerford Keynes due to the heatwave in July 2022. The lower reaches of the river are called the Tideway, derived from its long tidal reach up to Teddington Lock. Its tidal section includes most of its London stretch and has a rise and fall of .

Baltic Sea
The Baltic Sea is an arm of the Atlantic Ocean that is enclosed by Denmark, Estonia, Finland, Germany, Latvia, Lithuania, Poland, Russia, Sweden and the North and Central European Plain. The sea stretches from 53°N to 66°N latitude and from 10°E to 30°E longitude. A marginal sea of the Atlantic, with limited water exchange between the two water bodies, the Baltic Sea drains through the Danish Straits into the Kattegat by way of the Øresund, Great Belt and Little Belt. It includes the Gulf of Bothnia, the Bay of Bothnia, the Gulf of Finland, the Gulf of Riga and the Bay of Gdańsk. The " Baltic Proper" is bordered on its northern edge, at latitude 60°N, by Åland and the Gulf of Bothnia, on its northeastern edge by the Gulf of Finland, on its eastern edge by the Gulf of Riga, and in the west by the Swedish part of the southern Scandinavian Peninsula. The Baltic Sea is connected by artificial waterways to the White Sea via the White Sea–Baltic Canal and to the German ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thames Ironworks And Shipbuilding Company
The Thames Ironworks and Shipbuilding Company, Limited was a shipyard and iron works straddling the mouth of Bow Creek at its confluence with the River Thames, at Leamouth Wharf (often referred to as Blackwall) on the west side and at Canning Town on the east side. Its main activity was shipbuilding, but it also diversified into civil engineering, marine engines, cranes, electrical engineering and motor cars.Jim Lewis 1999, ''London's Lea Valley'', Phillimore, The company notably produced iron work for Isambard Kingdom Brunel's Royal Albert Bridge over the Tamar in the 1850s, and the world's first all-iron warship, HMS ''Warrior'', launched in 1860. History 1837–46 The company originated in 1837 as the Ditchburn and Mare Shipbuilding Company, founded by shipwright Thomas J. Ditchburn and the engineer and naval architect Charles John Mare. Originally located at Deptford, after a fire destroyed their yard the company moved to Orchard Place in 1838, between the East In ...

Crimean War
The Crimean War, , was fought from October 1853 to February 1856 between Russia and an ultimately victorious alliance of the Ottoman Empire, France, the United Kingdom and Piedmont-Sardinia. Geopolitical causes of the war included the decline of the Ottoman Empire, the expansion of the Russian Empire in the preceding Russo-Turkish Wars, and the British and French preference to preserve the Ottoman Empire to maintain the balance of power in the Concert of Europe. The flashpoint was a disagreement over the rights of Christian minorities in Palestine, then part of the Ottoman Empire, with the French promoting the rights of Roman Catholics, and Russia promoting those of the Eastern Orthodox Church. The churches worked out their differences with the Ottomans and came to an agreement, but both the French Emperor Napoleon III and the Russian Tsar Nicholas I refused to back down. Nicholas issued an ultimatum that demanded the Orthodox subjects of the Ottoman Empire be placed ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
