HMS Lady Nelson (1798)
His Majestys Armed Survey Vessel ''Lady Nelson'' was commissioned in 1799 to survey the coast of Australia. At the time large parts of the Australian coast were unmapped and Britain had claimed only part of the continent. The British Government were concerned that, in the event of settlers of another European power becoming established in Australia, any future conflict in Europe would lead to a widening of the conflict into the southern hemisphere to the detriment of the trade that Britain sought to develop. It was against this background that ''Lady Nelson'' was chosen to survey and establish sovereignty over strategic parts of the continent. ''Lady Nelson'' left Portsmouth on 18 March 1800 and arrived at Sydney on 16 December 1800 after having been the first vessel to reach the east coast of Australia via Bass Strait. Prior to that date all vessels had sailed around the southern tip of Tasmania to reach their destination. ''Lady Nelson''s survey work commenced shortly after he ...

Builder's Old Measurement
Builder's Old Measurement (BOM, bm, OM, and o.m.) is the method used in England from approximately 1650 to 1849 for calculating the cargo capacity of a ship. It is a volumetric measurement of cubic capacity. It estimated the tonnage of a ship based on length and maximum beam (nautical), beam. It is expressed in "tons burden" ( en-em , burthen , enm , byrthen ), and abbreviated "tons bm". The formula is: : \text = \frac where: * ''Length'' is the length, in foot (length), feet, from the stem (ship), stem to the sternpost; * ''Beam (nautical), Beam'' is the maximum beam, in feet. The Builder's Old Measurement formula remained in effect until the advent of steam propulsion. Steamships required a different method of estimating tonnage, because the ratio of length to beam was larger and a significant volume of internal space was used for boilers and machinery. In 1849, the Moorsom System was created in the United Kingdom. The Moorsom system calculates the cargo-carrying capaci ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
John Schank
Admiral John Schank (6 February 1823) was an officer of the British Royal Navy known for his skill in ship construction and mechanical design. Biography He was the son of Alexander Schank of Castlerig, Fife, Scotland. He entered the Royal Navy when young. His remarkable skills at mechanical design earned him the nickname "Old Purchase" following his design and construction of a cot fitted with pulleys that allowed it to be adjusted by the person lying in it. As a lieutenant in 1776, he was placed in charge of assembling ships to battle the American Revolutionaries on Lake Champlain. In less than six weeks, he constructed , which he then commanded as part of a fleet that defeated General Benedict Arnold's fleet in October 1776. His talents as an engineer were applied in General John Burgoyne's expedition to the building of floating bridges. After being made a captain in 1783, he brought before the Admiralty his design for ships with a sliding keel which allowed navigation of sh ...

George Bass
George Bass (; 30 January 1771 – after 5 February 1803) was a British naval surgeon and explorer of Australia. Early years Bass was born on 30 January 1771 at Aswarby, a hamlet near Sleaford, Lincolnshire, the son of a tenant farmer, George Bass, and a local beauty named Sarah (née Newman). His father died in 1777 when Bass was 6. He had attended Boston Grammar School and later trained in medicine at the hospital in Boston, Lincolnshire. At the age of 18, he was accepted in London as a member of the Company of Surgeons, and in 1794 he joined the Royal Navy as a surgeon. He arrived in Sydney in New South Wales on HMS ''Reliance'' on 7 September 1795. Also on the voyage were Matthew Flinders, John Hunter, Bennelong, and his surgeon's assistant William Martin. The voyages of the Tom Thumb and Tom Thumb II Bass had brought with him on the ''Reliance'' a small boat with an keel and beam, which he called the Tom Thumb on account of its size. In October 1795 Bass and Flin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Roaring Forties
The Roaring Forties are strong westerly winds found in the Southern Hemisphere, generally between the latitudes of 40°S and 50°S. The strong west-to-east air currents are caused by the combination of air being displaced from the Equator towards the South Pole, the Earth's rotation, and the scarcity of landmasses to serve as windbreaks at those latitudes. The Roaring Forties were a major aid to ships sailing the Brouwer Route from Europe to the East Indies or Australasia during the Age of Sail, and in modern times are favoured by yachtsmen on round-the-world voyages and competitions. The boundaries of the Roaring Forties are not consistent: The wind-stream shifts north or south depending on the season. The strong and continuous winds in the Roaring Forties make this zone highly prospective for wind power such as in New Zealand and Tasmania. Similar but even stronger conditions that occur at more southerly latitudes are called the Furious Fifties and the Shrieking or Screa ...

Simon's Bay
Simon's Town ( af, Simonstad), sometimes spelled Simonstown, is a town in the Western Cape, South Africa and is home to Naval Base Simon's Town, the South African Navy's largest base. It is located on the shores of False Bay, on the eastern side of the Cape Peninsula. For more than two centuries it has been a naval base and harbour (first for the British Royal Navy and now the South African Navy). The town is named after Simon van der Stel, an early governor of the Cape Colony. Topography The land rises steeply from near the water's edge and the town is boxed in along the shoreline by the heights above. The small harbour itself is protected from swells by a breakwater that was built with thousands of huge blocks of sandstone quarried out of the face of the mountain above. Simon's Town is now in effect a suburb of the City of Cape Town Metropolitan Municipality. The Simon's Town railway station is the terminus of the Southern Line, a railway line that runs south of the central ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Table Bay
Table Bay (Afrikaans: ''Tafelbaai'') is a natural bay on the Atlantic Ocean overlooked by Cape Town (founded 1652 by Van Riebeeck) and is at the northern end of the Cape Peninsula, which stretches south to the Cape of Good Hope. It was named because it is dominated by the flat-topped Table Mountain. History Bartolomeu Dias was the first European to explore this region in 1486. The bay, although famous for centuries as a haven for ships, is actually a rather poor natural harbour and is exposed to storm waves from the northwest. Many sailing ships seeking refuge in the bay during the 17th and 18th centuries were driven ashore by winter storms. The Dutch colonists nevertheless persisted with their efforts on the shores of Table Bay, because good natural harbours along this coastline are almost non-existent. The best of them, Saldanha Bay, lacked fresh water. Simon's Bay was well protected from westerly winter storms and swells, but more exposed to summer southeasterliy storm ...

Santiago, Cape Verde
Santiago (Portuguese for “ Saint James”) is the largest island of Cape Verde, its most important agricultural centre and home to half the nation's population. Part of the Sotavento Islands, it lies between the islands of Maio ( to the east) and Fogo ( to the west). It was the first of the islands to be settled: the town of Ribeira Grande (now Cidade Velha and a UNESCO World Heritage Site) was founded in 1462. Santiago is home to the nation's capital city of Praia. History The eastern side of the nearby island of Fogo collapsed into the ocean 73,000 years ago, creating a tsunami 170 meters high which struck Santiago. In 1460, António de Noli became the first to visit the island. Da Noli settled at ''Ribeira Grande'' (now Cidade Velha) with his family members and Portuguese from Algarve and Alentejo in 1462.Valor simbóli ...

New Holland (Australia)
''New Holland'' ( nl, Nieuw-Holland) is a historical European name for mainland Australia. The name was first applied to Australia in 1644 by the Dutch seafarer Abel Tasman. The name came for a time to be applied in most European maps to the vaunted "Southern land" or ''Terra Australis'' even after its coastline was finally explored. The continent of Antarctica, later named in the 1890s, was still in largely speculative form; it resumed the name ''Terra Australis'' (sometimes suffixed ''Non Cognita'', unknown). Its existence had been speculated on in some maps since the 5th century, under the theory of "balancing hemispheres". Lieutenant James Cook, captain of HMS ''Endeavour'', claimed the eastern portion of the Australian continent for the British Crown in 1770, naming it New South Wales. The British settlement of Sydney as a colony in 1788 prompted Britain to formally claim the east coast as New South Wales, leading to a search for a new collective name. New Holland ...

Matthew Flinders
Captain Matthew Flinders (16 March 1774 – 19 July 1814) was a British navigator and cartographer who led the first inshore circumnavigation of mainland Australia, then called New Holland. He is also credited as being the first person to utilise the name ''Australia'' to describe the entirety of that continent including Van Diemen's Land (now Tasmania), a title he regarded as being "more agreeable to the ear" than previous names such as ''Terra Australis''. Flinders was involved in several voyages of discovery between 1791 and 1803, the most famous of which are the circumnavigation of Australia and an earlier expedition when he and George Bass confirmed that Van Diemen's Land was an island. While returning to Britain in 1803, Flinders was arrested by the French governor at Isle de France (Mauritius). Although Britain and France were at war, Flinders thought the scientific nature of his work would ensure safe passage, but he remained under arrest for more than six years. In ...

James Grant (navigator)
James Grant (1772 – 11 November 1833) was a Scottish born British Royal Navy officer and navigator in the early nineteenth century. He served in Australia in 1800-1801 and was the first to map parts of the south coast of Australia. Early life Grant was baptized on 6 September 1772 at Forres, Morayshire, Scotland. He was educated at King's College, Aberdeen, under Dr. William Chalmers. He entered the Royal Navy as a captain's servant in August 1793 and was appointed a midshipman in May 1794. He passed his board for promotion to lieutenant and was promoted in 1800. Voyages of exploration Thanks to his friendship with Captain John Schank, as a lieutenant he took command of , a new vessel of 60 tons fitted with a centre-board (or "Schank") keel, towards the end of 1799 he sailed from the River Thames for Port Jackson on 18 March 1800.
