Royal Navy
The Royal Navy (RN) is the United Kingdom's naval warfare force. Although warships were used by English and Scottish kings from the early medieval period, the first major maritime engagements were fought in the Hundred Years' War against France. The modern Royal Navy traces its origins to the early 16th century; the oldest of the UK's armed services, it is consequently known as the Senior Service. From the middle decades of the 17th century, and through the 18th century, the Royal Navy vied with the Dutch Navy and later with the French Navy for maritime supremacy. From the mid 18th century, it was the world's most powerful navy until the Second World War. The Royal Navy played a key part in establishing and defending the British Empire, and four Imperial fortress colonies and a string of imperial bases and coaling stations secured the Royal Navy's ability to assert naval superiority globally. Owing to this historical prominence, it is common, even among non-Britons, to ref ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
George Spencer, 2nd Earl Spencer
George John Spencer, 2nd Earl Spencer, (1 September 1758 – 10 November 1834), styled Viscount Althorp from 1765 to 1783, was a British Whig politician. He served as Home Secretary from 1806 to 1807 in the Ministry of All the Talents. He was also the father of The Venerable Father Ignatius Spencer, a Roman Catholic convert to the priesthood.

First Lord Of The Admiralty
The First Lord of the Admiralty, or formally the Office of the First Lord of the Admiralty, was the political head of the English and later British Royal Navy. He was the government's senior adviser on all naval affairs, responsible for the direction and control of the Admiralty, and also of general administration of the Naval Service of the Kingdom of England, Great Britain in the 18th century, and then the United Kingdom, including the Royal Navy, the Royal Marines, and other services. It was one of the earliest known permanent government posts. Apart from being the political head of the Naval Service the post holder was simultaneously the pre-eminent member of the Board of Admiralty. The office of First Lord of the Admiralty existed from 1628 until it was abolished when the Admiralty, Air Ministry, Ministry of Defence, and War Office were all merged to form the new Ministry of Defence in 1964. Its modern-day equivalent is the Secretary of State for Defence. History In 1628 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gunboat
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 ...

Gun-brig
A gun-brig was a small brig-rigged warship that enjoyed popularity in the Royal Navy during the Napoleonic Wars, during which large numbers were purchased or built. In general these were vessels of under 200 tons burthen, and thus smaller than the more common s or the even larger s. The gun-brigs generally carried 12 guns, comprising two long guns in the chase position and ten carronades on the broadsides. For brig-rigged sloops, see List of corvette and sloop classes of the Royal Navy. For gunboats, see List of gunboat and gunvessel classes of the Royal Navy. Development The earliest gun-brigs were shallow-draught vessels. Initially they were not brigs at all, but were classed as 'gunvessels' and carried a schooner or brigantine rig. They were re-rigged as brigs about 1796 and re-classed under the new term 'gun-brig'. They were designed as much to row as to sail, and carried their primary armament firing forward - a pair of long 18-pounders or 24-pounders, weapons which in ...

Sloop
A sloop is a sailboat with a single mast typically having only one headsail in front of the mast and one mainsail aft of (behind) the mast. Such an arrangement is called a fore-and-aft rig, and can be rigged as a Bermuda rig with triangular sails fore and aft, or as a gaff-rig with triangular foresail(s) and a gaff rigged mainsail. Sailboats can be classified according to type of rig, and so a sailboat may be a sloop, catboat, cutter, ketch, yawl, or schooner. A sloop usually has only one headsail, although an exception is the Friendship sloop, which is usually gaff-rigged with a bowsprit and multiple headsails. If the vessel has two or more headsails, the term cutter may be used, especially if the mast is stepped further towards the back of the boat. When going before the wind, a sloop may carry a square-rigged topsail which will be hung from a topsail yard and be supported from below by a crossjack. This sail often has a large hollow foot, and this foot is sometimes fil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Survey Vessel
A survey vessel is any type of ship or boat that is used for underwater surveys, usually to collect data for mapping or planning underwater construction or mineral extraction. It is a type of research vessel, and may be designed for the purpose, modified for the purpose or temporarily put into the service as a vessel of opportunity, and may be crewed, remotely operated, or autonomous. The size and equipment vary to suit the task and availability. Role The task of survey vessels is to map the bottom, and measure the characteristics of the benthic zone, full water column, and surface for the purpose of: * hydrography, the measurement and description of the physical features of oceans and other natural bodies of water, and the prediction of their change over time, for the primary purpose of safety of navigation and in support of other activities associated with those bodies of water, * general oceanography, the scientific study of the oceans, * mapping of marine habitats as part ...

Thames Conservancy
The Thames Conservancy (formally the Conservators of the River Thames) was a body responsible for the management of the that river in England. It was founded in 1857 to replace the jurisdiction of the City of London up to Staines. Nine years later it took on the whole river from Cricklade in Wiltshire to the sea at Yantlet Creek on the Isle of Grain. Its territory was reduced when the Tideway (upper and lower estuary) was transferred to the Port of London Authority in 1909. In 1974 the conservancy was taken into the Thames Water Authority, later to devolve to the Environment Agency in almost all respects. History Background The stretch of river between the town of Staines, just to the west of London, and Yantlet Creek had been claimed by the City of London since 1197 under a charter of Richard the Lionheart. The jurisdiction was marked by the London Stones. In 1771 the Thames Navigation Commission was established from a body created twenty years earlier to handle navigatio ...

Dredging
Dredging is the excavation of material from a water environment. Possible reasons for dredging include improving existing water features; reshaping land and water features to alter drainage, navigability, and commercial use; constructing dams, dikes, and other controls for streams and shorelines; and recovering valuable mineral deposits or marine life having commercial value. In all but a few situations the excavation is undertaken by a specialist floating plant, known as a dredger. Dredging is carried out in many different locations and for many different purposes, but the main objectives are usually to recover material of value or use, or to create a greater depth of water. Dredges have been classified as suction or mechanical. Dredging has significant environmental impacts: it can disturb marine sediments, leading to both short- and long-term water pollution, destroy important seabed ecosystems, and can release human-sourced toxins captured in the sediment.
