Clipper Round The World Race
The Clipper Round the World Yacht Race is a biennial race that takes paying amateur crews on one or more legs of a circumnavigation of the globe in 11 specially-designed identical yachts owned by Clipper Ventures. Professional skippers and additional qualified persons (AQPs) lead each teams on the 10-month journey. All participants must complete a four week training course before starting the race. The race was conceived in 1995 by Sir Robin Knox-Johnston and is run by Clipper Ventures plc. The race has been held every two years since 1996, although in 2004 there was not a race and biennial racing resumed in 2005. In contrast to the now-defunct Global Challenge, the Clipper Race route follows the prevailing currents and winds and uses lighter, faster boats. The current fleet of 11 yachts are Clipper 70 yachts that were first used in the 2013–14 race. Previous race fleets were composed of eight Clipper 60s and ten Clipper 68s. Initial races did not feature corporate or spons ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Taeping
The ''Taeping'' was a clipper ship built in 1863 by Robert Steele & Company of Greenock and owned by Captain Alexander Rodger of Cellardyke, Fife. Taeping participated in The Great Tea Race of 1866 and narrowly defeated the ''Ariel''. The ship's captain was Donald MacKinnon (Dòmhnall ’ic Nèill ’ic Dhòmnaill Ruaidh) of Heanish, Tiree. It was wrecked on 22 September 1871 by Ladd's Reef in the South China Sea while traveling to New York. Sailing performance According to Basil Lubbock, the tea clippers ''Taeping'', '' Fiery Cross'', ''Serica'' and ''Lahloo'' performed at their best in light breezes, as they were all rigged with single topsail A topsail ("tops'l") is a sail set above another sail; on square-rigged vessels further sails may be set above topsails. Square rig On a square rigged vessel, a topsail is a typically trapezoidal shaped sail rigged above the course sail and ...s.

Iceland
Iceland ( is, Ísland; ) is a Nordic island country in the North Atlantic Ocean and in the Arctic Ocean. Iceland is the most sparsely populated country in Europe. Iceland's capital and largest city is Reykjavík, which (along with its surrounding areas) is home to over 65% of the population. Iceland is the biggest part of the Mid-Atlantic Ridge that rises above sea level, and its central volcanic plateau is erupting almost constantly. The interior consists of a plateau characterised by sand and lava fields, mountains, and glaciers, and many glacial rivers flow to the sea through the lowlands. Iceland is warmed by the Gulf Stream and has a temperate climate, despite a high latitude just outside the Arctic Circle. Its high latitude and marine influence keep summers chilly, and most of its islands have a polar climate. According to the ancient manuscript , the settlement of Iceland began in 874 AD when the Norwegian chieftain Ingólfr Arnarson became the first p ...

Rigging
Rigging comprises the system of ropes, cables and chains, which support a sailing ship or sail boat's masts—''standing rigging'', including shrouds and stays—and which adjust the position of the vessel's sails and spars to which they are attached—the ''running rigging'', including halyards, braces, sheets and vangs. Etymology According to the Encyclopædia Britannica Eleventh Edition "rigging" derives from Anglo-Saxon ''wrigan'' or ''wringing'', "to clothe". The same source points out that "rigging" a sailing vessel refers to putting all the components in place to allow it to function, including the masts, spars, sails and the rigging. Types of rigging Rigging is divided into two classes, ''standing'', which supports the mast (and bowsprit), and ''running'', which controls the orientation of the sails and their degree of reefing. Configurations differ for each type of rigging, between ''fore-and-aft rigged'' vessels and ''square-rigged'' vessels. Standing Standin ...

Camper And Nicholsons
Camper and Nicholson was a yacht design and manufacturing company based in Gosport, England, for over two hundred years, constructing many significant vessels, such as Gipsy Moth IV and Prince Philip, Duke of Edinburgh, Prince Philip's yacht Bloodhound (yacht), Bloodhound. Its customers included Thomas Sopwith, William Kissam Vanderbilt II and George Spencer-Churchill, 6th Duke of Marlborough. Its yachts competed in America's Cup, The America's Cup, The Fastnet Race, the Olympic Games, Olympics, the Ocean Race (1973–1974 Whitbread Round the World Race, Whitbread Round the World Race) and many other yacht races. Today the name is used by a yacht brokerage firm. History Origin In 1782 Francis Calense Amos (1748–1824), who had trained as a shipwright in London, founded a shipyard in Gosport, leasing the land from the Royal Naval Dockyard. Initially he built and repaired small boats for local fishermen. In 1809 he took on his great-nephew, William Camper (1794-1863) as his appr ...

IRC (Sailing)
IRC is a system of handicapping sailboats and yachts for the purpose of racing. It is managed by the Royal Ocean Racing Club (RORC) in the United Kingdom through their dedicated Rating Office, and the Union Nationale pour la Course au Large (UNCL) in France. IRC stands for International Rating Certificate. Originally, “IR” was an abbreviation for International Rule. However, since the Rule at that stage was not recognized under International Rule (sailing), that name was not permitted. So RORC simply decided to keep the initials as the name, and the name remained simply IRC until 2016. The IRC rule is not published, meaning the only bodies capable of calculating an IRC rating are the RORC Rating Office and UNCL Centre de Calcul in Paris (they are joint owners of the Rule). This prevents designers from attempting to design 'to the rule'. The earlier IOR was published, and often amended, resulting in widespread criticism for several reasons. Firstly, as the rule effectively d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Draft (hull)
The draft or draught of a ship's hull is the vertical distance between the waterline and the bottom of the hull (keel). The draught of the vessel is the maximum depth of any part of the vessel, including appendages such as rudders, propellers and drop keels if deployed. Draft determines the minimum depth of water a ship or boat can safely navigate. The related term air draft is the maximum height of any part of the vessel above the water. The more heavily a vessel is loaded, the deeper it sinks into the water, and the greater its draft. After construction, the shipyard creates a table showing how much water the vessel displaces based on its draft and the density of the water (salt or fresh). The draft can also be used to determine the weight of cargo on board by calculating the total displacement of water, accounting for the content of the ship's bunkers, and using Archimedes' principle. The closely related term "trim" is defined as the difference between the forward and aft ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Beam (nautical)
The beam of a ship is its width at its widest point. The maximum beam (BMAX) is the distance between planes passing through the outer extremities of the ship, beam of the hull (BH) only includes permanently fixed parts of the hull, and beam at waterline (BWL) is the maximum width where the hull intersects the surface of the water. Generally speaking, the wider the beam of a ship (or boat), the more initial stability it has, at the expense of secondary stability in the event of a capsize, where more energy is required to right the vessel from its inverted position. A ship that heels on her ''beam ends'' has her deck beams nearly vertical. Typical values Typical length-to-beam ratios ( aspect ratios) for small sailboats are from 2:1 (dinghies to trailerable sailboats around ) to 5:1 (racing sailboats over ). Large ships have widely varying beam ratios, some as large as 20:1. Rowing shells designed for flatwater racing may have length to beam ratios as high as 30:1, while a cor ...

Waterline Length
A vessel's length at the waterline (abbreviated to L.W.L)Note: originally Load Waterline Length is the length of a ship or boat at the level where it sits in the water (the ''waterline''). The LWL will be shorter than the length of the boat overall (''length overall'' or LOA) as most boats have bows and stern protrusions that make the LOA greater than the LWL. As a ship becomes more loaded, it will sit lower in the water and its ambient waterline length may change; but the registered L.W.L it is measured from a default load condition. This measure is significant in determining several of a vessel's properties, such as how much water it displaces, where the bow and stern waves occur, hull speed, amount of bottom-paint needed, etc. Traditionally, a stripe called the "boot top" is painted around the hull just above the waterline. In sailing boats, longer waterline length will usually enable a greater maximum speed, because it allows greater sail area, without increasing beam or d ...

Length Overall
__NOTOC__ Length overall (LOA, o/a, o.a. or oa) is the maximum length of a vessel's hull measured parallel to the waterline. This length is important while docking the ship. It is the most commonly used way of expressing the size of a ship, and is also used for calculating the cost of a marina berth (for example, £2.50 per metre LOA). LOA is usually measured on the hull alone. For sailing ships, this may ''exclude'' the bowsprit and other fittings added to the hull. This is how some racing boats and tall ships use the term LOA. However, other sources may include bowsprits in LOA. Confusingly, LOA has different meanings. "Sparred length", "Total length including bowsprit", "Mooring length" and "LOA including bowsprit" are other expressions that might indicate the full length of a sailing ship. LOD Often used to distinguish between the length of a vessel including projections (e.g. bow sprits, etc.) from the length of the hull itself, the Length on Deck or LOD is often repor ...

Displacement (ship)
The displacement or displacement tonnage of a ship is its weight. As the term indicates, it is measured indirectly, using Archimedes' principle, by first calculating the volume of water displaced by the ship, then converting that value into weight. Traditionally, various measurement rules have been in use, giving various measures in long tons. Today, tonnes are more commonly used. Ship displacement varies by a vessel's degree of load, from its empty weight as designed (known as "lightweight tonnage") to its maximum load. Numerous specific terms are used to describe varying levels of load and trim, detailed below. Ship displacement should not be confused with measurements of volume or capacity typically used for commercial vessels and measured by tonnage: net tonnage and gross tonnage. Calculation The process of determining a vessel's displacement begins with measuring its draft.George, 2005. p.5. This is accomplished by means of its "draft marks" (or "load lines"). A mer ...

Monohull
image:monohull.svg, right A monohull is a type of boat having only one hull (watercraft), hull, unlike multihulled boats which can have two or more individual hulls connected to one another. Fundamental concept Among the earliest hulls were simple logs, but these were generally unstable and tended to roll over easily. Hollowing out the logs into a dugout canoe doesn't help much unless the hollow section penetrates below the log's center of buoyancy, then a load carried low in the cavity actually stabilizes the craft. Adding weight or Sailing ballast, ballast to the bottom of the hull or as low as possible within the hull adds stability. Naval architects place the center of gravity substantially below the center of buoyancy; in most cases this can only be achieved by adding weight or ballast. The use of stones and other weights as ballast can be traced back to the Ancient Rome, Romans, Phoenicians and Vikings. Modern ships carry tons of ballast in order to maintain their stabil ...
