One-design Racing
One-design racing is a racing method which may be adopted in sports which use complex equipment, whereby all vehicles have identical or very similar designs or models, avoiding the need for a Handicapping, handicap system. Sailing There are two primary methods of competition in sailboat racing: One-design and Handicap (sailing), handicap racing (e.g. Portsmouth Yardstick, PHRF, Performance Handicap Racing Fleet and LYS (sailing), Leading Yard Stick). One design refers to a racing class that consists of just one model or design of sailboat. In one-design racing, the first boat to finish wins the race. This is contrasted with handicap racing, where time is added or subtracted from the finishing times based on design factors and mathematical formulas to determine the winner. In between One-design and handicap racing, a number of other approaches exist. One-design classes can be contrasted with a Sailing (sport)#Development Classes, development class, the classic example being the Am ...

Racing
In sport, racing is a competition of speed, in which competitors try to complete a given task in the shortest amount of time. Typically this involves traversing some distance, but it can be any other task involving speed to reach a specific goal. A race may be run continuously to finish or may be made up of several segments called heats, stages or legs. A heat is usually run over the same course at different times. A stage is a shorter section of a much longer course or a time trial. Early records of races are evident on pottery from ancient Greece, which depicted running men vying for first place. A chariot race is described in Homer's ''Iliad''. Etymology The word ''race'' comes from a Norse word. This Norse word arrived in France during the invading of Normandy and gave the word ''raz'' which means "swift water" in Brittany, as in a mill race; it can be found in "Pointe du Raz" (the most western point of France, in Brittany), and "''raz-de-marée''" (tsunami). The word rac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cost Of Ownership
Total cost of ownership (TCO) is a financial estimate intended to help buyers and owners determine the direct and indirect costs of a product or service. It is a management accounting concept that can be used in full cost accounting or even ecological economics where it includes social costs. For manufacturing, as TCO is typically compared with doing business overseas, it goes beyond the initial manufacturing cycle time and cost to make parts. TCO includes a variety of cost of doing business items, for example, ship and re-ship, and opportunity costs, while it also considers incentives developed for an alternative approach. Incentives and other variables include tax credits, common language, expedited delivery, and customer-oriented supplier visits. Use of concept TCO, when incorporated in any financial benefit analysis, provides a cost basis for determining the total economic value of an investment. Examples include: return on investment, internal rate of return, economic value ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
J/24
The J/24 is an international One-Design and Midget Ocean Racing Club trailerable keelboat class built by J/Boats and defined by World Sailing. The J/24 was created to fulfill the diverse needs of recreational sailors such as cruising, one design racing, day sailing, and handicap racing.Henkel, Steve: ''The Sailor's Book of Small Cruising Sailboats'', page 294. International Marine/McGraw-Hill, 2010. The J/24 class has more than 50,000 people sailing 5,500 boats worldwide; is established in 27 countries with well and is the world's most popular one design keelboat. Production In the summer of 1975 Rodney Johnstone designed and built hull number 1 in his garage in Stonington, Connecticut. "Ragtime" would serve as the master mold for the subsequent hulls. This design allowed him to start the very successful J-Boat company with his brother Bob Johnstone. By 1978 the class was popular enough to hold a one-design regatta in Key West with twenty boats on the line. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dragon (keelboat)
Dragon racing in 2008. The Dragon is a one-design keelboat designed by Norwegian Johan Anker in 1929. In 1948 the Dragon became an Olympic Class, a status it retained until the Munich Olympics in 1972. The Dragon's long keel and elegant metre-boat lines remain unchanged, but today Dragons are constructed using the latest technology to make the boat durable and easy to maintain. GRP construction was introduced in 1973 and the rigging has been regularly updated. The Dragon class is actively represented in over 26 countries on 5 continents. By 2004 there were 1,444 boats registered, and the number of boats built has averaged 45 per year. There are many more which are used for day sailing. The World Championships are held in every odd year and the European Championships are held annually. The Gold Cup, which can only be held in certain specified European countries, is unique in that all six races count without discard. It is held annually and often attracts over 100 entries, usua ...

Specification
A specification often refers to a set of documented requirements to be satisfied by a material, design, product, or service. A specification is often a type of technical standard. There are different types of technical or engineering specifications (specs), and the term is used differently in different technical contexts. They often refer to particular documents, and/or particular information within them. The word ''specification'' is broadly defined as "to state explicitly or in detail" or "to be specific". A requirement specification is a documented requirement, or set of documented requirements, to be satisfied by a given material, design, product, service, etc. It is a common early part of engineering design and product development processes in many fields. A functional specification is a kind of requirement specification, and may show functional block diagrams. A design or product specification describes the features of the ''solutions'' for the Requirement Specification, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Optimist (dinghy)
The Optimist is a small, single-handed sailing dinghy intended for use by young people up to the age of 15. The Optimist is one of the two most popular sailing dinghies in the world, with over 150,000 boats officially registered with the class and many more built but never registered. It is sailed in over 120 countries and it is one of only two sailboats as an International Class by World Sailing exclusively for sailors under 16. Origin The Optimist was designed in 1947 by American Clark Mills at the request of the Clearwater Florida Optimist service club following a proposal by Major Clifford McKay to offer low-cost sailing for young people. The Optimist Club ran a soap box derby, but wanted more than a single-day event. Thus they were looking for a low-cost equivalent for sailing. He designed a simple pram that could be built from two 4' x 8' sheets of plywood, and donated the plan to the Optimists. The design was slightly modified and introduced to Europe by Axel Damg ...

470 (dinghy)
The 470 (Four-Seventy) is a double-handed monohull planing dinghy with a centreboard, Bermuda rig, and centre sheeting. Equipped with a spinnaker, trapeze and a large sail-area-to-weight ratio, it is designed to plane easily, and good teamwork is necessary to sail it well. The name comes from the boat's length of . The 470 is a popular class with both individuals and sailing schools, offering a good introduction to high-performance boats without being excessively difficult to handle, but it is not a boat designed for beginners. Its smaller sister, the 420, is a stepping stone to the 470. The 470 is a World Sailing International Class and has been an Olympic class since the 1976 games. History The 470 was designed in 1963 by the Frenchman André Cornu as a modern fibreglass planing dinghy to appeal to sailors of different sizes and ages. This formula succeeded, and the boat spread around the world. In 1969, the class was given international status and it has been an Olympic cl ...

Finn (dinghy)
The Finn dinghy is a single-handed, cat-rigged sailboat, and a former Olympic class for men's sailing. Since its debut at the 1952 Summer Olympics in Helsinki, the Finn has featured in every summer Olympics, making it the longest serving dinghy in the Olympic Regatta and one of the most prolific Olympic sailboats, currently filling the slot for the Heavyweight Dinghy. The Finn is a physically demanding boat to race at the highest levels, especially since the class rules now allow unlimited boat rocking and sail pumping when the wind is above 10 knots. The event will not feature on the Olympic programme from 2024. Design The Finn was designed by Swedish canoe designer, Rickard Sarby, in 1949 for the Helsinki Olympics. in 1952 the hulls were built of timber and the sails were of cotton. Initially there was little understanding of the role of a mast which could bend to reduce power. However over time the Finn sailors learned how to plane timber off the front of their masts for h ...

Herreshoff 12½ (keelboat)
The Herreshoff 12½ Footer is a one-design keelboat. History Nathanael Greene Herreshoff designed the 12½ footer in 1914. It has been in continuous production since then, and is nearly universally acclaimed as one of the finest small boats of all time He was 66 years old by then, and had all the experience from a full and legendary career of designing and building yachts. He had already accumulated 5 of the never-matched record of 6 consecutive America’s Cup defenses, and 6 consecutive victories. The Herreshoff Manufacturing Company took the first orders for the 12½ footer in 1914 and built 364 wooden hulls through 1943. Following the closing of HMC production, the Quincy Adams Yacht Yard was licensed by HMC to build the design. Quincy Adams used the Herreshoff builder’s plate, and built 51 hulls from 1943 through 1948. The Quincy Adams boats had hull numbers in the 2000s, and were planked with mahogany rather than the white cedar used by HMC. They also have something o ...

Laser (dinghy)
The Laser is a class of Single-handed sailing, single-handed, one-design dinghy sailing, sailing dinghies using a common hull design with three interchangeable rigs of different sail areas, appropriate to a given combination of wind strength and crew weight. Bruce Kirby (yachts), Bruce Kirby designed the Laser in 1970 with an emphasis on simplicity and performance. The Laser is a widely produced class of dinghies. As of 2018, there were more than 215,000 boats worldwide. It is an international class with sailors in 120 countries, and an Olympic class since 1996. Its wide acceptance is attributable to its robust construction, simple rig and ease of sailing that offer competitive racing due to tight class association controls which eliminate differences in hull, sails, and equipment. The International Laser Class Association (ILCA) defines the specifications and competition rules for the boat, which is officially referred to as the ILCA Dinghy, due to a trademark dispute.
