Lightvessel stations of Great Britain
Résumé
The history of the many lightvessel stations of Great Britain goes back over 250 years to the placement of the world's first lightship at the Nore in the early 18th century.
A lightvessel station is a named position at which a lightvessel was placed, rather than a particular ship; individual vessels were often transferred between different stations during their existence. Stations themselves were occasionally changed, especially during wartime, when lights were only displayed in response to specific shipping needs.
The world's first lightvessel was the result of a business partnership between Robert Hamblin, a former barber and ship manager from King's Lynn, and David Avery, an investor. In 1730 the pair secured a government licence to moor a ship, with a prominent light affixed to it, to serve as a navigation aid at the Nore in the Thames mouth. Hamblin and Avery intended to profit from the vessel by collecting a fee from passing merchant vessels. The licence was opposed by Trinity House, which considered that it possessed a monopoly on construction and maintenance of navigation aids in British waters. After extensive legal dispute the licence was revoked in 1732 and Trinity House assumed direct responsibility for the proposed lightship; Hamblin and Avery were granted nominal lease revenues in exchange. The Nore lightship commenced operations in 1734.
A second lightvessel was placed at the Dudgeon station, off the Norfolk coast, in 1736, with others following at Owers Bank (1788) and the Goodwin Sands (1793). While the Admiralty opposed the 1802 Sunk lightvessel, claiming it would aid enemy ships, it soon afterwards placed three vessels of its own to protect the fleet during the Napoleonic Wars; they were taken over by Trinity House a few years later. Many others were commissioned during the nineteenth century, especially off England's east coast and the approaches to the Thames, where there were many treacherous shoals.
