Thomas W. Lawson (ship)
''Thomas W. Lawson'' was a seven-masted, steel-hulled schooner built for the Pacific trade, but used primarily to haul coal and oil along the East Coast of the United States. Named for copper baron Thomas W. Lawson (businessman), Thomas W. Lawson, a Boston millionaire, stock-broker, book author, and president of the Boston Bay State Gas, Bay State Gas Co., she was launched in 1902 as the largest schooner and largest sailing vessel without an auxiliary engine ever built. ''Thomas W. Lawson'' was destroyed off the uninhabited island of Annet, Isles of Scilly, Annet, in the Isles of Scilly, in a storm on December 14, 1907, killing all but two of her eighteen crew and a harbor pilot already aboard. Her cargo of 58,000 barrels of light Kerosene, paraffin oil caused perhaps the first large marine List of oil spills, oil spill. Development and construction Designed by naval architect Bowdoin B.

Schooner 'Thomas W
A schooner () is a type of sailing vessel defined by its rig: fore-and-aft rigged on all of two or more masts and, in the case of a two-masted schooner, the foremast generally being shorter than the mainmast. A common variant, the topsail schooner also has a square topsail on the foremast, to which may be added a topgallant. Differing definitions leave uncertain whether the addition of a fore course would make such a vessel a brigantine. Many schooners are gaff-rigged, but other examples include Bermuda rig and the staysail schooner. The origins of schooner rigged vessels is obscure, but there is good evidence of them from the early 17th century in paintings by Dutch marine artists. The name "schooner" first appeared in eastern North America in the early 1700s. The name may be related to a Scots word meaning to skip over water, or to skip stones. The schooner rig was used in vessels with a wide range of purposes. On a fast hull, good ability to windward was useful for privat ...

Spanker (sail)
On a square rigged ship, the spanker is a gaff-rigged fore-and-aft sail set from and aft of the aftmost mast. Spankers are also called ''driver'', ''jigger'', and a ''pusher'' sail. On a schooner of four or more masts, the spanker is the sail on the mast nearest the stern. The spanker is a small sail, but as it is so far aft of the balance point of the hull, it has strong leverage: when sheeted in, the spanker is important in driving the boat to a new tack TACK is a group of archaea acronym for Thaumarchaeota (now Nitrososphaerota), Aigarchaeota, Crenarchaeota (now Thermoproteota), and Korarchaeota, the first groups discovered.

Yacht
A yacht is a sailing or power vessel used for pleasure, cruising, or racing. There is no standard definition, though the term generally applies to vessels with a cabin intended for overnight use. To be termed a , as opposed to a , such a pleasure vessel is likely to be at least in length and may have been judged to have good aesthetic qualities. The Commercial Yacht Code classifies yachts and over as . Such yachts typically require a hired crew and have higher construction standards. Further classifications for large yachts are: —carrying no more than 12 passengers, —solely for the pleasure of the owner and guests, or by flag, the country under which it is registered. A superyacht (sometimes ) generally refers to any yacht (sail or power) longer than . Racing yachts are designed to emphasize performance over comfort. Charter yachts are run as a business for profit. As of 2020 there were more than 15,000 yachts of sufficient size to require a professional crew. Etymology ...

List Of Oil Spills
This is a reverse-chronological list of oil spills that have occurred throughout the world and spill(s) that are currently ongoing. Quantities are measured in tonnes of crude oil with one tonne roughly equal to 308 US gallons, 256 Imperial gallons, 7.33 Barrel (unit), barrels, or 1165 litres. This calculation uses a median value of 0.858 for the specific gravity of light crude oil; actual values can range from 0.816 to 0.893, so the amounts shown below are inexact. They are also estimates, because the actual volume of an oil spill is difficult to measure exactly. Confirmed spills Investigation underway Note: The "flow rate" column applies to leaking wells, pipelines, etc., and is often used to estimate the total amount of oil spilled. The "full cargo" column applies to vessels, vehicles, etc., and represents the maximum amount of oil that could be spilled. The "spilled" columns indicate the total amount of oil that has been released to the environment so far, and should b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kerosene
Kerosene, paraffin, or lamp oil is a combustible hydrocarbon liquid which is derived from petroleum. It is widely used as a fuel in aviation as well as households. Its name derives from el, κηρός (''keros'') meaning "wax", and was registered as a trademark by Canadian geologist and inventor Abraham Gesner in 1854 before evolving into a generic trademark. It is sometimes spelled kerosine in scientific and industrial usage. The term kerosene is common in much of Argentina, Australia, Canada, India, New Zealand, Nigeria, and the United States, while the term paraffin (or a closely related variant) is used in Chile, eastern Africa, South Africa, Norway, and in the United Kingdom. The term lamp oil, or the equivalent in the local languages, is common in the majority of Asia and the Southeastern United States. Liquid paraffin (called mineral oil in the US) is a more viscous and highly refined product which is used as a laxative. Paraffin wax is a waxy solid extracted from pet ...

Annet, Isles Of Scilly
Annet ( kw, Anet, ''kittiwake'') is the second largest of the fifty or so uninhabited Isles of Scilly, west of St Agnes with a length of and approximately in area. The low-lying island is almost divided in two by a narrow neck of land at West Porth which can, at times, be covered by waves. At the northern end of the island are the two granite carns of Annet Head and Carn Irish and three smaller carns known as the Haycocks. The rocky outcrops on the southern side of the island, such as South Carn, are smaller. Annet is a bird sanctuary and the main seabird breeding site in Scilly.Robinson, P. (2003) The Birds of the Isles of Scilly. London: Christopher Helm. The island is closed to the public all year round to limit the disturbance to the breeding seabirds during the summer months and breeding Atlantic Grey Seals during the winter months, for which it has been designated a Site of Special Scientific Interest (SSSI). It is also within part of the Isles of Scilly Area of Outsta ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Coal
Coal is a combustible black or brownish-black sedimentary rock, formed as rock strata called coal seams. Coal is mostly carbon with variable amounts of other elements, chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial over millions of years. Vast deposits of coal originate in former wetlands called coal forests that covered much of the Earth's tropical land areas during the late Carboniferous ( Pennsylvanian) and Permian times. Many significant coal deposits are younger than this and originate from the Mesozoic and Cenozoic eras. Coal is used primarily as a fuel. While coal has been known and used for thousands of years, its usage was limited until the Industrial Revolution. With the invention of the steam engine, coal consumption increased. In 2020, coal supplied about a quarter of the world's primary energy and over a third of its electricity. Some iron ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Knot (unit)
The knot () is a unit of speed equal to one nautical mile per hour, exactly (approximately or ). The ISO standard symbol for the knot is kn. The same symbol is preferred by the Institute of Electrical and Electronics Engineers (IEEE), while kt is also common, especially in aviation, where it is the form recommended by the International Civil Aviation Organization (ICAO). The knot is a non- SI unit. The knot is used in meteorology, and in maritime and air navigation. A vessel travelling at 1 knot along a meridian travels approximately one minute of geographic latitude in one hour. Definitions ;1 international knot = :1 nautical mile per hour (by definition), : (exactly), : (approximately), : (approximately), : (approximately) : (approximately). The length of the internationally agreed nautical mile is . The US adopted the international definition in 1954, having previously used the US nautical mile ().

Winch
A winch is a mechanical device that is used to pull in (wind up) or let out (wind out) or otherwise adjust the tension of a rope or wire rope (also called "cable" or "wire cable"). In its simplest form, it consists of a spool (or drum) attached to a hand crank. Traditionally, winches on ships accumulated wire or rope on the drum; those that do not accumulate, and instead pass on the wire/rope (see yacht photo above), are called capstans. Despite this, sailboat capstans are most often referred to as winches. Winches are the basis of such machines as tow trucks, steam shovels and elevators. More complex designs have gear assemblies and can be powered by electric, hydraulic, pneumatic or internal combustion drives. It might include a solenoid brake and/or a Mechanical brake stretch wrapper, mechanical brake or ratchet (device), ratchet and pawl which prevents it unwinding unless the pawl is retracted. The rope may be stored on the winch. When trimming a line on a sailboat, the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
