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 lightship was located off the Nore sandbank at the mouth of the River Thames in London, England, by its inventor Robert Hamblin in 1734. Lightships have since been rendered obsolete by advancing lighthouse construction techniques, and 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.
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.
Trinity Buoy Wharf is the site of a lighthouse, by the confluence of the River Thames and Bow Creek on the Leamouth Peninsula, Poplar. It lies within the London Borough of Tower Hamlets. The lighthouse no longer functions, but is the home of various art projects such as Longplayer. It is sometimes known as Bow Creek Lighthouse.
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.
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.
Light Vessel Number 83 (LV-83) Swiftsure is a lightship and museum ship owned by Northwest Seaport in Seattle, Washington. Launched in 1904 at Camden, New Jersey and in active service until 1960 after serving on all five of the American west coast's lightship stations, it is the oldest surviving lightship in the United States, the only one still fitted with its original steam engine, and the last lightship with wooden decks. LV-83 was designated a National Historic Landmark in 1989, and has been undergoing major restoration since 2008.
United States Lightship 101, now known as Portsmouth as a museum ship, was first stationed at Cape Charles, Virginia. Today she is at the Portsmouth Naval Shipyard Museum in Portsmouth, Virginia. Portsmouth never had a lightship station; however, when the vessel was dry docked there as a museum, she took on the pseudonym Portsmouth. A National Historic Landmark, she is one of a small number of surviving lightships.
Old Hunstanton Lighthouse is a former lighthouse located in Old Hunstanton in the English county of Norfolk, generally called Hunstanton Lighthouse during its operational life. It was built at the highest point available on this part of the coast, on top of Hunstanton Cliffs, and served to help guide vessels into the safe water of Lynn Deeps. Although the present lighthouse was built in 1840, there had been a lighthouse on the site since the 17th century. Prior to the establishment of the Lynn Well light vessel in 1828, Hunstanton Lighthouse provided the only visible guide to ships seeking to enter The Wash at night.
Winterton Lighthouse is located in Winterton-on-Sea in the English county of Norfolk. In 1845 Winterton Ness was described as being 'well known to the mariner as the most fatal headland between Scotland and London'. As well as marking the headland, the lighthouse was intended to help guide vessels into the Cockle Gat, which provided the northern entry into the safe water of Yarmouth Roads. The lighthouse was known to Daniel Defoe and is mentioned in his novel Robinson Crusoe.
North Carr is the last remaining Scottish lightship. She is 101 feet (31 m) in length, 25 feet (7.6 m) in beam and 268 tons.
Dorothea Weber was a 190 GRT three-masted schooner that was built in 1922 as the barge Lucy by J Oelkers, Hamburg. She was later renamed Midgard I, Midgard IV and then Elisabeth before a sale in 1935 saw her fitted with a diesel engine and renamed Dorothea Weber. She was seized by the Allies in May 1945 at Guernsey, passed to the Ministry of War Transport (MoWT) and renamed Empire Cononley.
SS Mona's Isle was a steam turbine passenger ship that was built in Scotland in 1905 as Onward, renamed Mona's Isle in 1920, and scrapped in Wales in 1948. She was designed as an English Channel ferry for the South Eastern and Chatham Railway (SE&CR), who operated her between Folkestone and Boulogne. In 1920 the Isle of Man Steam Packet Company (IoMSP) bought her and renamed her Mona's Isle. The IoMSP ran her mainly on summer services linking Douglas with Dublin and Belfast. She was the fourth IoMSP ship to be called Mona's Isle.
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 Inner and Outer Dowsing sand banks are shallow-water shoals off the Lincolnshire coast of the UK sector of southern North Sea. They have been used for navigation, as a commercial fishery, for aggregate dredging, and more recently as the location for major offshore wind farms.
Light Vessel 95 is a former lightship that has been used as a recording studio since the early 2000s. She was built by Philip and Son at Dartmouth, Devon, in 1939 for Trinity House, the body responsible for provision of maritime navigation aids in England and Wales. Light Vessel 95 served at Goodwin Sands, The Wash, Varne Bank and at the Sevenstones Station. She was among the last ten light vessels in Trinity House service and was converted to automatic operation in the 1990s. Light Vessel 95 was sold in 2003 and converted into a recording studio. Since 2008 she has been moored at Trinity Buoy Wharf in London.
Light Vessel 16 is a former Trinity House lightship originally stationed off Yorkshire, England. Built in 1840, she is the oldest surviving wooden lightship.
