Lightvessel East Goodwin
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 off the Nore sandbank at the mouth of the River Thames in England, placed there by its inventor Robert Hamblin in 1734. The type has become largely obsolete; lighthouses replaced some stations as the construction techniques for lighthouses advanced, while large, automated buoys replaced others. Construction A crucial element of lightvessel design is the mounting of a light on a sufficiently tall mast. Initially, it consisted of oil lamps that could be run up the mast and lowered for servicing. Later vessels carried fixed lamps which were serviced in place. Fresnel lenses were used as they became available, and many vessels housed them in small versions of the lanterns used in lighthouses. Some light ...

Lightship Finngrundet
The Lightship Finngrundet is a lightvessel built in 1903 and now a museum ship moored in Stockholm, Sweden. History She was the second Finngrundet lightvessel, built in Gävle, Sweden in 1903 and replacing one dating from 1859. She was stationed on the Finngrund banks in the Baltic Sea northeast of Gävle during the ice-free part of the year. She was extensively modified in a refit in 1927 at Öregrunds Ship och Varvs AB, the original paraffin light being replaced with an AGA beacon. The fog bell was augmented with a "nautophone" fog signal and an underwater fog signal. Further modifications carried out in 1940 included the addition of wireless communication along with equipment for her to function as a weather station, and the electrification of her light. Her final refit was in 1957 when the deckhouse and crew space were modified. The optics were built by G.W. Lyth of Stockholm. They are mounted 11.5 metres above sea level and had a range of around . Two flashes were produce ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Anchor
An anchor is a device, normally made of metal , used to secure a vessel to the bed of a body of water to prevent the craft from drifting due to wind or current. The word derives from Latin ''ancora'', which itself comes from the Greek ἄγκυρα (ankȳra). Anchors can either be temporary or permanent. Permanent anchors are used in the creation of a mooring, and are rarely moved; a specialist service is normally needed to move or maintain them. Vessels carry one or more temporary anchors, which may be of different designs and weights. A sea anchor is a drag device, not in contact with the seabed, used to minimise drift of a vessel relative to the water. A drogue is a drag device used to slow or help steer a vessel running before a storm in a following or overtaking sea, or when crossing a bar in a breaking sea.. Overview Anchors achieve holding power either by "hooking" into the seabed, or mass, or a combination of the two. Permanent moorings use large masses (common ...

Former Breaksea Lightvessel
A former is an object, such as a template, gauge or cutting die, which is used to form something such as a boat's hull. Typically, a former gives shape to a structure that may have complex curvature. A former may become an integral part of the finished structure, as in an aircraft fuselage, or it may be removable, being using in the construction process and then discarded or re-used. Aircraft formers Formers are used in the construction of aircraft fuselage, of which a typical fuselage has a series from the nose to the empennage, typically perpendicular to the longitudinal axis of the aircraft. The primary purpose of formers is to establish the shape of the fuselage and reduce the column length of stringers to prevent instability. Formers are typically attached to longerons, which support the skin of the aircraft. The "former-and-longeron" technique (also called stations and stringers) was adopted from boat construction, and was typical of light aircraft built until the ad ...

Calshot Spit Lightship
Calshot is a coastal village in Hampshire, England at the west corner of Southampton Water where it joins the Solent.OS Explorer Map, New Forest, Scale: 1:25 000.Publisher: Ordnance Survey B4 edition (2013). History In 1539, Henry VIII ordered the construction of Calshot Castle, at the end of Calshot Spit, to defend the port of Southampton from attack. Its strategic importance continues to the present day, and there is still a military presence in Calshot, though the castle is no longer a manned fort. Calshot is notable for its role in the development of aircraft and flying boats. In 1913 the Royal Flying Corps established Calshot Naval Air Station (later known as RNAS Calshot and RAF Calshot) at the end of Calshot Spit. It was also at one point home to Lawrence of Arabia. Calshot Lifeboat Station was established in 1970 by the RNLI. Relationship with Tristan da Cunha Following a volcanic eruption in 1961, the population of the Tristan da Cunha islands was evacuated to Cals ...

Cohasset, Massachusetts
Cohasset is a town in Norfolk County, Massachusetts, United States. As of the 2020 census the population was 8,381. History Cohasset was inhabited for thousands of years by Native Americans prior to European colonization, from whom English colonists would adapt the town's name. The area is first mentioned by Europeans in 1614, when Captain John Smith explored the coast of New England and described an encounter of his ship with four Native Americans in a canoe at ''Quonahasit'', two of whom were shot by the Europeans. In 1634, "Conihosset" is listed as a "noted habitation" in New England in a list of both indigenous and colonial settlements, though the area was first settled by English settlers in 1670 suggesting this was a settlement of Massachusett people. The town's name came from the Massachusett word "Conahasset," possibly meaning "long rocky place" or "fishing promontory." Much of the land was originally granted without consultation of its indigenous inhabitants to the ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

North Carr Light Ship 1988
North is one of the four compass points or cardinal directions. It is the opposite of south and is perpendicular to east and west. ''North'' is a noun, adjective, or adverb indicating direction or geography. Etymology The word ''north'' is related to the Old High German ''nord'', both descending from the Proto-Indo-European unit *''ner-'', meaning "left; below" as north is to left when facing the rising sun. Similarly, the other cardinal directions are also related to the sun's position. The Latin word ''borealis'' comes from the Greek '' boreas'' "north wind, north", which, according to Ovid, was personified as the wind-god Boreas, the father of Calais and Zetes. ''Septentrionalis'' is from ''septentriones'', "the seven plow oxen", a name of ''Ursa Major''. The Greek ἀρκτικός (''arktikós'') is named for the same constellation, and is the source of the English word ''Arctic''. Other languages have other derivations. For example, in Lezgian, ''kefer'' can mean b ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Rule Of Thumb
In English, the phrase ''rule of thumb'' refers to an approximate method for doing something, based on practical experience rather than theory. This usage of the phrase can be traced back to the 17th century and has been associated with various trades where quantities were measured by comparison to the width or length of a thumb. A modern folk etymology holds that the phrase is derived from the maximum width of a stick allowed for wife-beating under English common law, but no such law ever existed. This belief may have originated in a rumored statement by 18th-century judge Sir Francis Buller that a man may beat his wife with a stick no wider than his thumb. The rumor produced numerous jokes and satirical cartoons at Buller's expense, but there is no record that he made such a statement. English jurist Sir William Blackstone wrote in his ''Commentaries on the Laws of England'' of an "old law" that once allowed "moderate" beatings by husbands, but he did not mention thumbs or any ...
