Nautical Measured Mile
A nautical measured mile is a nautical mile which is marked by two pairs of towers. A mile is measured by sailing on a given bearing and lining up the pairs of towers. The start of the mile is recorded when the first pair of towers line up and the end of the mile recorded when the second pair line up. To accurately measure performance ships must make at least four to six runs in both directions to allow for the wind and tide. There are several nautical measured miles around the British Isles: * Between Talland Bay and Hannafore, West Looe, Cornwall. * At Skelmorlie, North Ayrshire, Scotland. * There are four Admiralty Distance Poles at St Abb's Head, Berwickshire, Scotland. * There are two consecutive miles on the Isle of Arran, Scotland between South Sannox and Corloch. See also *Navigation transit markers Navigation Transit Markers are posts placed alongside a navigation to allow powered craft to check their speed. Examples of these markers can be fou ...

Nautical Mile
A nautical mile is a unit of length used in air, marine, and space navigation, and for the definition of territorial waters. Historically, it was defined as the meridian arc length corresponding to one minute ( of a degree) of latitude. Today the international nautical mile is defined as exactly . The derived unit of speed is the knot, one nautical mile per hour. Unit symbol There is no single internationally agreed symbol, with several symbols in use. * M is used as the abbreviation for the nautical mile by the International Hydrographic Organization. * NM is used by the International Civil Aviation Organization. * nmi is used by the Institute of Electrical and Electronics Engineers and the United States Government Publishing Office. * nm is a non-standard abbreviation used in many maritime applications and texts, including U.S. Government Coast Pilots and Sailing Directions. It conflicts with the SI symbol for nanometre. History The word mile is from the Latin word ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bearing (navigation)
In navigation, bearing or azimuth is the horizontal angle between the direction of an object and north or another object. The angle value can be specified in various angular units, such as degrees, mils, or grad. More specifically: * Absolute bearing refers to the angle between the magnetic north (''magnetic bearing'') or true north (''true bearing'') and an object. For example, an object to due east would have an absolute bearing of 90 degrees. Thus, it is the same as azimuth.U.S. Army, ''Advanced Map and Aerial Photograph Reading'', Headquarters, War Department, Washington, D.C. (17 September 1941), pp. 24-2/ref> * #Relative, Relative bearing refers to the angle between the craft's forward direction (heading) and the location of another object. For example, an object relative bearing of 0 degrees would be immediately in front; an object relative bearing 180 degrees would be behind. Bearings can be measured in mils, points, or degrees. Thus, it is the same as an ''azimuth ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Talland
Talland ( kw, Tallan) is a hamlet and ecclesiastical parish between Looe and Polperro on the south coast of Cornwall (the parish includes the eastern part of the village of Polperro, where there is a chapel of ease and formerly also the town of West Looe).

Skelmorlie
Skelmorlie is a village in North Ayrshire in the south-west of Scotland. Although it is the northernmost settlement in the council area of North Ayrshire, it is contiguous with Wemyss Bay, which is in Inverclyde.

Scotland
Scotland (, ) is a country that is part of the United Kingdom. Covering the northern third of the island of Great Britain, mainland Scotland has a border with England to the southeast and is otherwise surrounded by the Atlantic Ocean to the north and west, the North Sea to the northeast and east, and the Irish Sea to the south. It also contains more than 790 islands, principally in the archipelagos of the Hebrides and the Northern Isles.

Scotland is divided into 32 administrative subdivisions or local authorities, known as council areas. Glasgow City is the largest council area in terms of population, with Highland being the largest in terms of area. Limited self-governing power, covering matters such as education, social services and roads and transportation, is devolved from the Scott ...

St Abb's Head
St Abb's Head is a rocky promontory by the village of St Abbs in Scottish Borders, Scotland, and a national nature reserve administered by the National Trust for Scotland. St Abb's Head Lighthouse was designed and built by the brothers David Stevenson and Thomas Stevenson and began service on 24 February 1862. Geology The layered sedimentary rocks of greywacke and siltstone which lie to the north and south of the Head were laid down at the bottom of the sea between 460 and 410 million years ago. The Head itself is made from hard volcanic rock which formed as lava flowed from volcanoes around 400 million years ago. The different type of rocks accounts for the contrast in colour between the rocks of the Head and those of mainland cliffs. The softer sedimentary rocks have eroded over time, leaving behind the high headland made from the harder rock. However even this tough volcanic rock has been affected by the actions of the sea, leaving steep gullies and sea stacks which are ...

Berwickshire
Berwickshire ( gd, Siorrachd Bhearaig) is a historic county, registration county and lieutenancy area in south-eastern Scotland, on the English border. Berwickshire County Council existed from 1890 until 1975, when the area became part of the Borders region, with most of the historic county becoming part of the lower-tier Berwickshire district. Berwickshire district was abolished in 1996, when all the districts in the Borders region merged to become the Scottish Borders council area. The county takes its name from Berwick-upon-Tweed, its original county town, which was part of Scotland at the time of the county's formation in the twelfth century, but became part of England in 1482 after several centuries of swapping back and forth between the two kingdoms. After the loss of Berwick, Duns and Greenlaw both served as county town at different periods. The low-lying part of Berwickshire between the Tweed and the Lammermuirs is known as "the Merse", from an old Scots word for a ...
