The Corporation of Trinity House of Deptford Strond, also known as Trinity House, is the official authority for lighthouses in England, Wales, the Channel Islands and Gibraltar. Trinity House is also responsible for the provision and maintenance of other navigational aids, such as lightvessels, buoys, and maritime radio/satellite communication systems. It is also an official deep sea pilotage authority, providing expert navigators for ships trading in Northern European waters.
A lightvessel, or lightship, is a ship that acts as a lighthouse. They are used in waters that are too deep or otherwise unsuitable for lighthouse construction. Although some records exist of fire beacons being placed on ships in Roman times, the first modern lightvessel was located off the Nore sandbank at the mouth of the River Thames in London, England, and placed there by its inventor Robert Hamblin in 1734. Lightships have become largely obsolete; some being replaced by lighthouses as construction techniques advanced, others by large automated navigation buoys.
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.
Lightvessels in Ireland describes any lightvessel or light float previously stationed off the coast of Ireland. The Commissioners of Irish Lights are responsible for the majority of marine navigation aids around the whole of the island of Ireland.
Goodwin Sands is a 10-mile-long (16 km) sandbank at the southern end of the North Sea lying 6 miles (10 km) off the Deal coast in Kent, England. The area consists of a layer of approximately 25 m (82 ft) depth of fine sand resting on an Upper Chalk platform belonging to the same geological feature that incorporates the White Cliffs of Dover. The banks lie between 0.5 m above the low water mark to around 3 m (10 ft) below low water, except for one channel that drops to around 20 m (66 ft) below. Tides and currents are constantly shifting the shoals.
The Spurn Lightship is a lightvessel, previously anchored in Hull Marina in the British city of Kingston upon Hull, England. It was relocated to a shipyard in October 2021 for restoration, prior to becoming a display together with the Arctic Corsair.
The Nore is a long bank of sand and silt running along the south-centre of the final narrowing of the Thames Estuary, England. Its south-west is the very narrow Nore Sand. Just short of the Nore's easternmost point where it fades into the channels it has a notable point once marked by a lightship on the line where the estuary of the Thames nominally becomes the North Sea. A lit buoy today stands on this often map-marked divisor: between Havengore Creek in east Essex and Warden Point on the Isle of Sheppey in Kent.
The station named Nantucket or Nantucket Shoals was served by a number of lightvessels that marked the hazardous Nantucket Shoals south of Nantucket Island. The vessels, given numbers as their "name," had the station name painted on their hulls when assigned to the station. Several ships have been assigned to the Nantucket Shoals lightship station and have been called Nantucket. It was common for a lightship to be reassigned and then have the new station name painted on the hull. The Nantucket station was a significant US lightship station for transatlantic voyages. Established in 1854, the station marked the limits of the dangerous Nantucket Shoals. She was the last lightship seen by vessels departing the United States, as well as the first beacon seen on approach. The position was 40 miles (64 km) southeast of Nantucket Island, the farthest lightship in North America, and experienced clockwise rotary tidal currents.
The United States lightship Huron (LV-103) is a lightvessel that was launched in 1920. She is now a museum ship moored in Pine Grove Park, Port Huron, St. Clair County, Michigan.
Ocean Village is a mixed-use marina, residential, business and leisure development on the mouth of the River Itchen in Southampton, on the south coast of England. Originally the site of Southampton's first working docks, the "Outer Dock" which opened in 1842, the area was redeveloped in 1986 and became the leisure marina it is today. After experiencing a period of stalled development with the late-2000s recession, Ocean Village underwent another series of major, multimillion-pound redevelopment projects. Current recreational facilities include a cinema, cafes, wine bars and restaurants.
Sevenstones Lightship is a lightvessel station off the Seven Stones Reef which is nearly 15 miles (24 km) to the west-north-west (WNW) of Land's End, Cornwall, and 7 miles (11 km) east-north-east (ENE) of the Isles of Scilly. The reef has been a navigational hazard to shipping for centuries with seventy-one named wrecks and an estimated two hundred shipwrecks overall, the most infamous being the oil tanker Torrey Canyon on 18 March 1967. The rocks are only exposed at half tide. Since it was not feasible to build a lighthouse, a lightvessel was provided by Trinity House. The first was moored near the reef on 20 August 1841 and exhibited its first light on 1 September 1841. She is permanently anchored in 40 fathoms (73 m) and is 2.5 miles (4.0 km) north-east (NE) of the reef. Since 1987, the Sevenstones Lightship has been automated and unmanned.
United States lightship Relief (WLV-605) is a lightvessel now serving as a museum ship in Oakland, California. Built in 1950, she is one of a small number of surviving lightships, and one of an even smaller number built specifically for the United States Coast Guard. Along with her sister ship, the WLV-604 Columbia, she is a good example of the last generation of lightships built. She was declared a National Historic Landmark in 1989.
LANBY, a contraction of Large Automatic Navigation BuoY, was a type of floating navigational aid designed to replace lightships. Now obsolete, they were originally made in the USA by General Dynamics and adapted by Hawker Siddeley Dynamics for use in British waters in the early 1970s. They consisted of a circular hull with a raised central structure containing a 360° light and foghorn, and sometimes also a radio beacon. They were monitored from onshore and designed to run for extended periods without repair. Their running costs were estimated to be as low as 10% of those of lightships.
RNLB Mary Stanford was the Ballycotton Lifeboat from 1930 to 1959. Ballycotton is on Ireland's southern coast, a trade route to the Americas. There are many dangerous rocks and shallows with on-shore prevailing winds. Ballycotton has a long tradition of life-saving. Mary Stanford had 41 rescues, or "shouts", and saved 122 lives. She performed the notable Daunt Lightship rescue on 11 February 1936. After her withdrawal from service she lay for some years in a backwater of Dublin's Grand Canal Dock, but has now been returned to Ballycotton and restored.
Lightvessel No. XVII Gedser Rev is a decommissioned lightvessel built in 1895, now serving as a museum ship in Helsingør, Denmark, having formerly been stationed in the Nyhavn Canal in Copenhagen. It is owned by the National Museum and takes its name after Gedser Rev south of Falster where it was stationed most of its working life.
The Kentish Knock is a long shoal in the North Sea east of Essex, England. It is the most easterly of those of the Thames Estuary and its core, which is shallower than 18 feet (5.5 m), extends 6 miles (9.7 km). Thus it is a major hazard to deep-draught navigation. It is exactly 28 miles (45 km) due east of Foulness Point, Essex and is centred about 15 miles (24 km) NNE of North Foreland, Kent – both are extreme points of those counties.
The Sandettie Bank is an elongated sandbank in the southern North Sea, more specifically about in the middle of the northeastern entrance to the Strait of Dover. North-west of it are the hazardous Goodwin Sands, south of it the sandbank Ruytingen.
The Nantucket Lightship or United States Lightship WLV-612 is a lightvessel commissioned in 1950 that became the last lightship decommissioned in United States Coast Guard service.
Suriname-Rivier is a lightvessel permanently berthed in a wet dock in the Fort Nieuw-Amsterdam Open-Air Museum in Nieuw-Amsterdam, Commewijne, Suriname.
