Dinghy sailing is the activity of sailing small boats by using five essential controls:

#872127

79-501: The Shannon One Design sailing dinghy is an open centreboard sailing boat raced on the River Shannon , Lough Derg and Lough Ree in Ireland . The boats are 18 feet (5.5 m) long by 4 feet 10.5 inches (1.486 m) beam, drawing 4 feet (1.2 m) with her centreboard down. They have a sail area of 140 square feet (15.6m2) set in a single sail , giving the boat what

158-739: A large yacht as one that is 24 metres (79 ft) or more at the waterline and is in commercial use for sport or pleasure, while not carrying cargo or more than 12 passengers and carrying a professional crew. The code regulates the equipping of such vessels, both at sea and in port—including such matters as crew duty times and the presence of a helicopter on board. The code has different levels of standard for vessels above and below 500 gross tons . Such yachts may be considered superyachts and are more commonly at 40 metres (130 ft) or more in length. Other countries have standards similar to LY2. Whereas commercial large yachts may carry no more than 12 passengers, private yachts are solely for

237-483: A steam auxiliary engine . Early examples, driven with paddle wheels, had a railed platform from which the person conning the vessel could walk across the vessel above the main deck, the origin of the bridge . In the late 18th century, steam engines became more efficient, spars were removed and screw propellers became standard. Steam yachts evolved with the development of the steam engine . Ultimately, engines employed pistons driven by steam within cylinders, connected to

316-431: A 600-foot (180 m) yacht, REV Ocean , was under construction, which when launched would replace the 590-foot (180 m) Azzam as the longest superyacht. As superyachts have grown size, the distinction between a yacht and a ship (perhaps converted for personal use) has become unclear. A proposed definition for calling a vessel a yacht rather than a ship would if it was constructed solely for personal use and has

395-511: A breeze of wind, and a serious challenge to sail well in any conditions. As a result, SOD sailing attracts a wide range of sailors from far and wide, not simply limited to Shannon riverside dwellers. At the two main events each year, the week long regattas at Ballyglass on Lough Ree and Dromineer on Lough Derg , up to 55 SODs have been counted. These will be sailed by a mixture of local sailors and others based in Dublin or elsewhere (as far away as

474-525: A cabin intended for overnight use. To be termed a yacht , as opposed to a boat , such a pleasure vessel is likely to be at least 33 feet (10 m) in length and may have been judged to have good aesthetic qualities. The Commercial Yacht Code classifies yachts 79 ft (24 m) and over as large . Such yachts typically require a hired crew and have higher construction standards. Further classifications for large yachts are commercial : carrying no more than 12 passengers; private : solely for

553-665: A category, apart. Design considerations for a cruising yacht include seaworthiness, performance, sea kindliness, and cost of construction, as follows: Multihulls offer tradeoffs as cruising sailboats, compared with monohulls . They may be catamarans or trimarans. They rely on form stability—having separate hulls far apart—for their resistance to capsize. Their advantages include greater: stability, speed, (for catamarans) living space, and shallower draft. Their drawbacks include: greater expenses, greater windage , more difficult tacking under sail, less load capacity, and more maneuvering room required because of their broad beam. They come with

632-632: A combined occupancy of less than 100, including crew. The United States Coast Guard classifies motorboats—any vessel less than 65 feet (20 m), propelled by machinery—in four classes by length: A motor yacht's style can both be functional and evoke an aesthetic—trending towards the modern or the traditional. Among the styles, mentioned in the literature, are: There are three basic types of motor yacht hull: full-displacement , semi-displacement , and planing , which have progressively higher cruise speeds and hourly fuel consumption with increased engine power: A typical semi-displacement yacht has

711-520: A contest between the yacht, America , and its English competitors. Both countries had rules by which to rate yachts, the English by tonnage and the American by length. In the late 19th century, yacht owners would base their choice of vessel upon preferred lifestyle and budget, which would determine the size and type of vessel, which would most likely be a fore-and aft, two-masted sailing vessel. A treatise on

790-407: A crank shaft, which drove a propeller. Near the end of the 19th century, compound engines came into widespread use. Compound engines exhausted steam into successively larger cylinders to accommodate the higher volumes at reduced pressures, giving improved efficiency. These stages were called expansions, with double- and triple-expansion engines being common, especially in shipping where efficiency

869-554: A device now commonly known as the trapeze. At that time, it was known as King George's Jubilee Truss. The device was immediately banned by the Yacht Racing Committee on the grounds that it was unsporting and gave an unfair advantage to its users. Thunder & Lightning is now in the National Maritime Museum Cornwall . The innovative technique was immediately banned, and received little development until it

948-907: A few people make them some still sail with wooden boats), more responsive sail materials and design, easily transportable boats (many car-toppable), and simpler rigs such as gennakers instead of more complex spinnakers . These advances are more economical in time and money, and have greatly extended the appeal of dinghy sailing. In Britain , the RYA regulates racing and provides modular and accredited training courses for leisure and competitive sailing. A basic sailing course can be completed in several days. Similar organisations exist worldwide to administer and promote both leisure and competitive sailing. Some dinghies come into more than one category, either because boundaries overlap or because different categories are measuring different things; e.g. both "one design" boats and boats of much freer design can be found in each of

1027-421: A fiberglass hull with enough finely finished teak or mahogany to represent the "best of two worlds" approach. The fiberglass hull makes the boat maintenance easier and some think they are sturdier and will not corrode like wood. Examples of classic sailing dinghies are Minto , Mirror Dinghy , Fatty Knees , Trinka, Bauer, Whitehall, and Gig Harbor. Safety dinghies were designed to be used as yacht tenders with

1106-512: A fine house on the shores of a lake or ( Cork ) harbour", it was likely that "one" kept a yacht and a boatman as a means of going on house visits, going hunting, or accessing the railway. This very quickly evolved into rendezvous for picnics, joint manoeuvres and ultimately competition. Two of these clubs still surviving are the Lough Ree Yacht Club (Ballyglass, Athlone ), which traces its origins to Athlone Yacht Club est. 1770, making it

1185-518: A higher-aspect ratio fin keel with hydrodynamically efficient bulbs for ballast. On some racing yachts, a canting keel shifts angle from side to side to promote sailing with less heeling angle (sideway tilt), while other underwater foils take care of leeway (sideways motion). Motor yachts range in length from 33–130 feet (10–40 m) before they are considered super-yachts or mega-yachts , which are 130 feet (40 m) and longer. They also vary by use, by style, and by hull type. As of April 2020

1264-511: A meeting of representatives of Lough Ree Yacht Club , Lough Derg Yacht Club and North Shannon Yacht Club ( Lough Boderg ) held in the Prince of Wales Hotel, Athlone , on 29 January 1920. The committee commissioned a leading British designer of the time, F.C. Morgan-Giles . Later that year Morgan-Giles delivered the plans. The first boat was ordered from Walter Levinge of Creaghduff , Coosan , Athlone , Co. Westmeath and delivered in 1921. This boat

1343-506: A minimum weight and sail area. Classes which are not development classes are usually referred to as "One design". The idea is that One Designs provide a fair and level playing field for even competition, whereas Development Classes drive boat speed and technology forwards. The first one design was the Water Wag designed by Thomas Middleton, which first sailed in Dublin Bay in 1887. The class

1422-422: A mooring, while other (usually racing) boats can't be left on mooring because they will capsize, which can cause certain parts like the mast and hull to be damaged. Sailing skiffs are the fastest and arguably most difficult type of dinghy to sail. A skiff has a flat narrow hull with a disproportionately large sailplan, usually consisting of an asymmetric spinnaker, blade jib and fully battened main. Sailors manage

1501-479: A more prevalent type of power plant in the 20th century thanks to their low cost of operation and reliability. The Recreational Craft Directive requires that all vessels sold in the European Union and United Kingdom satisfy one of four design categories, based on the wind force and seas that they are designed to encounter: The Large Commercial Yacht Code (LY2) of Great Britain and its dominions defines

1580-610: A navigation station that allows planning the route. Onboard systems include: Modern yachts employ a suite of electronics for communication, measurement of surroundings, and navigation. Sailing yachts for cruising versus racing embody different tradeoffs between comfort and performance. Cruising yachts emphasize comfort over performance. Racing yachts are designed to compete against others in their class, while providing adequate comfort to their crews. Cruising yachts may be designed for near-shore use or for passage-making. They may also be raced, but they are designed and built with

1659-407: A new category of pleasure craft. The power plants started with the steam engine and transitioned to the internal combustion engine. Whereas sailing yachts continued to be steered from the after portion of the vessel, power yachts adopted the bridge in a forward cabin structure that afforded better forward and sideways visibility. The history of steam yachts starts with large sailing yachts with

1738-448: A private sailing boat presented to him when he returned from exile to England in the 17th century, and he sailed for recreation and competition. In 1887 Thomas Middleton, a Dublin solicitor, considered that yacht racing was becoming an excessively expensive activity, with boats becoming eclipsed by better designs each year. He proposed the 'One Model' principle. He wanted yacht racing to be an exercise of skill with all boats being built to

1817-640: A professional crew. The term, yacht , originates from the Dutch word jacht (pl. jachten ), which means "hunt", and originally referred to light, fast sailing vessels that the Dutch Republic navy used to pursue pirates and other transgressors around and into the shallow waters of the Low Countries . The history of pleasure boats begins with rowed craft in Pharaonic Egyptian times, and other vessels in

1896-467: A rotating mast. This allows the rig to be highly aerodynamic and the reduced drag from the thin hulls, gives a multihull its great speed advantage over traditional monohulls. Dinghy-sized multihulls are sometimes referred to as "Beach Catamarans or Beach Trimarans". The International 14 remains a popular racing class, having acquired racks (for trapezing crews) and a gennaker since its original design. The Laser Standard , Laser Radial and Laser 4.7 are

1975-570: A sliding scale of allowable modification or design differences; restricted classes would typically allow the movement of fittings or even parts of the boat around, but are unlikely to allow major changes to hull shape or sails. Truly open development classes are also almost unknown, the famous line about the 18 ft skiff "the boat shall be 18ft long and the race starts at 2 o'clock" is a myth but open classes will usually allow pretty radical changes within usually some kind of box rule which specifies depth, length, width of hull height of mast and sometimes

2054-492: A variety of sleeping accommodations and (for catamarans) bridge-deck configurations. Gaff rigs have been uncommon in the construction of cruising boats, since the mid 20th century. More common rigs are Bermuda , fractional , cutter , and ketch . Occasionally employed rigs since then have been the yawl , schooner, wishbone , catboat . Sailboats employ standing rigging to support the rig, running rigging to raise and adjust sails, cleats to secure lines, winches to work

2133-548: A wedge-shaped bow, which promotes penetrating waves, that transitions to flatter, wider surfaces aft, which promotes lifting the vessel out of the water—the "deep vee" hull, designed by Ray Hunt, found in approximately 75% of modern power boats. Cruising motor yachts are available in a range of styles as two-engine catamarans , ranging in length from 40–150 feet (12–46 m) with top speeds ranging from 20–60 knots (37–111 km/h). Motor yachts typically have one or more diesel engines . Gasoline-powered motors and engines are

2212-552: Is called a gunter rig . During the 19th and early 20th century racing was organised for 18'-0" long open centre board boats with one sail on the Shannon lakes. These boats were effectively a restricted class, restricted by length, beam and sail area. different lakeside and riverside builders adapted their traditional rowing boats to meet an owners preferences. The creation of the Shannon One Design sailing dinghy came about after

2291-482: Is still sailed today, well over a hundred years later. The first International one-design class was the B.R.A. 12 foot dinghy which was designed by George Cockshott in 1914 for West Kirby marine lake. This design expanded to Holland, Netherlands, Germany, France, Ireland etc. and further afield. All of the following classes can be used for recreational as well as racing purposes. Some function better for recreation use because they require less maintenance and can be left on

2370-568: Is the larger boat, while the GP14 has the edge for racing. However the Mirror and her larger sisters, and the Heron , can also be regarded as coming into this category. Classic dinghies are typically used as yacht tenders or shore boats, and emphasize beauty and versatility over sailing performance. Although some are still made entirely from wood, the majority of the most popular classic sailing dinghies combine

2449-431: Is the most popular choice for dinghy racing, but a windward leeward course is another popular option. Bob Bond "The Handbook of Sailing" DK & Pelham Books revised 1996 ISBN   0-7207-2016-8 Yacht A yacht ( / j ɒ t / ) is a sail - or motor -propelled watercraft made for pleasure, cruising, or racing. There is no standard definition, though the term generally applies to vessels with

2528-601: The 420 and Flying Junior . Sports boats : These classes are larger off-shore racing dinghies which shade off into classes of yachts with fixed keels. Usually they have several crew members as well as the helm. Melges 24 and Laser SB3 are current examples of this type. Development classes : Most dinghy classes have a fairly fixed layout of sails and hull design, and changes are very infrequent. However, some classes can compete and sail with less rigid definitions and measurements. This encourages experiment which often leads to innovation in techniques and construction. Examples are

2607-454: The Albacore , International 14 , National 12 , Jet 14 , Firefly and Flying Fifteen . The Scorpion was designed in 1959 by Taprell Dorling. He also introduced the major advance of hull shapes that can plane , and which can therefore reach beyond the usual speed limits for small sailing boats. In effect, a boat which is planing is skimming along the surface, with the bow of the boat not in

2686-463: The Avenger . He achieved 52 first places, two second places and three third places out of 57 race starts that year. Note: Graham Anderson in his 1999 book Fast Light Boats, a Century of Kiwi Innovation argues that planing centreboard sailing boats were introduced into New Zealand in the early 20th century – well before Uffa Fox popularised the concept. Another advance in dinghy sailing was introduced in

2765-596: The International 14 , National 12 , the 18ft Skiff , the Puddle Duck Racer and the Moth . The International Moth is worth noting because of its use of lifting foils on the rudder and daggerboard. These generate enough lift to push the hull above the water, significantly reducing friction and allowing speeds in excess of 25 knots (46 km/h). Racing is one of the most popular forms of dinghy sailing, and it contributes to

2844-960: The Wayfarer , arguably the GP14 , the Tideway , the Laser Stratos , the Drascombe series of dinghies, the CL 16 and the Laser 16, the Roamer Cruising Dinghy, designed by Eric Coleman an early member of the Dinghy Cruising Association, plus many designs of Iain Oughtred, John Welsford and François Vivier. Sailing these boats can still give much excitement. Cruiser-racer dinghies successfully combine elements of both

2923-406: The yachts of today. There has been some crossover, in that the sloop sail plan was adopted as standard and most convenient by early dinghy designers. The development of the sailing dinghy was helped in the early 20th century by Uffa Fox (1898–1972), an English boat designer and sailing enthusiast. He developed and contributed to many dinghy classes that are still with us nearly a century later:

3002-431: The 1930s, when the technique of trapezing was introduced. This involves using the crew to provide more leverage (than possible by hiking out) to keep the sails vertical and the boat balanced; doing this can prevent the boat from capsizing, by hanging outside the boat on a harness and rope attached to the 'hounds' or upper mast . As a result, the boat is easier to keep upright, and the sails can deliver maximum power most of

3081-427: The 1960s fiberglass became a prevalent material. These materials and others continue in use. Whereas yachts of 79 feet (24 m) and below may be constructed of fiberglass , larger yachts are more likely to be constructed of steel, aluminum or composite fiber-reinforced plastic . Depending on size, a cruising yacht is likely to have at least two cabins , a main salon and a forward stateroom . In smaller yachts,

3160-424: The English crown, Charles was presented with a yacht and later commissioned a series of royal yachts, which included at least one experimental catamaran . The first recorded yacht race between two vessels occurred in 1661, followed by the first open sailing competition in 1663 in English waters. Starting in 1739, England found itself in a series of wars—a period that saw a decline in yachting. In Ireland, however,

3239-729: The Osprey, the Thistle , the 14 ft John Spencer Javelin and the International 470 . They can all plane easily, even upwind and they use trapeze and a symmetric spinnaker. Not all are two handed boats: the International Contender and the RS600 are high performance single handed boats equipped with a trapeze, but not a spinnaker, and demonstrate a comparable performance. Skiffs are usually classed as High performance dinghies. Racing dinghies are designed for racing, but not all have necessarily

3318-453: The UK, states that, "With a reliance on nature and the elements, sailing ... is about adventure, exploration, teamwork and fun." There has always been a need for small tender boats for transporting goods and personnel to and from anchored sailing ships. Together with other smaller work craft such as fishing and light cargo, small inshore craft have always been in evidence. Charles II of England had

3397-473: The United States), most of whom return year on year to compete. It is not unusual to have two generations of the same family sailing together in a SOD or even have all three crew-members from the same family. There is also a very healthy influx of younger sailors joining the fleet to compete against older generations. The Shannon One Design Association (‘SODA’) is the governing body responsible for promotion of

3476-602: The added function of proactive self-rescue boat that can be sailed to safety. These boats are also used as recreational sailboats. Some of them can be fitted out with exposure canopies, sea anchors, and other survival gear. Examples of safety dinghies are the Portland Pudgy dinghy and the Clam dinghy. Multihulls are fast twin or three hulled boats that fall under the definition of dinghy. Unlike dinghies, multihulls have high aspect ratio rigs with fully battened mainsails and sometimes,

3555-435: The application of the " racing rules of sailing ", boat handling skills when starting and when rounding marks, and knowledge of tactics and strategy. Racing tactics include positioning the boat at different angles. To improve speed when racing, sailors should position themselves at the windward direction (closest to the direction of the wind) in order to get "clean air". The RYA , the regulating authority for sail training in

3634-554: The class and enforcement of the class rules. In 1989 they sanctioned changes to the original hull and rig plans to take into account new technologies. Sailing has flourished on the River Shannon, and especially on Loughs Allen , Key , Ree and Derg, for hundreds of years. Initially a means of transport, it gradually became a social event. In the eighteenth century, travel by water was the safest and most convenient way. Therefore, if you were one of those who could say that "one lived in

3713-453: The class is often called requires three people to race and this produces a very sociable form of sailing. Sailing SODs has always attracted families, and generations in many cases have been involved in campaigning the same boat down through the years. Indeed, many of the same family names that attended that first meeting in 1920 still feature in SOD racing today. The SOD is an exciting boat to sail in

3792-464: The comfort and amenities necessary for overnight voyages. Qualities considered in cruising yachts include: performance, comfort under way, ease of handling, stability, living comfort, durability, ease of maintenance, affordability of ownership. Cruising sailboats share the common attribute of providing overnight accommodations. They may be classified as small (easy to haul behind a trailer), near-shore and off-shore . Multihull sailing yachts are

3871-454: The development of sailing skills as well as to improvements in dinghy and sail construction and design. Sometimes the Olympic triangle is used as a course for dinghy races where space permits, particularly for events where there ought to be little local advantage such as State and National titles and for classes which are mainly displacement sailing such as the Heron (dinghy) . The olympic triangle

3950-516: The first quarter of the 20th century to provide evenly matched racing without handicaps. In 2010 the second episode BBC television series Three Men Go to Ireland featured the three men, Dara Ó Briain , Griff Rhys Jones and Rory McGrath , racing SODs adjacent to the Lough Derg Yacht Club the previous October. Dinghy sailing When racing , the above skills need to be refined and additional skills and techniques learned, such as

4029-514: The gentry enjoyed yachting and founded the first yacht club in Cork as the Cork Harbour Water Club in 1720. English yacht racing continued among the English gentry who founded England's oldest yacht club in 1775 to support a fleet at Cumberland . With maritime peace, starting in 1815, came a resurgence of interest in yachting. Boatbuilders, who had been making fast vessels both for smugglers and

4108-406: The government revenue cutters , turned their skills again to yachts. The fast yachts of the early 19th century were fore-and-aft luggers , schooners , and sloops . By the 1850s, yachts featured large sail areas, a narrow beam, and a deeper draft than was customary until then. Racing between yachts owned by wealthy patrons was common, with large wagers at stake. The America's Cup arose out of

4187-461: The immediately previous two groups, offering good racing performance and also being very viable cruising boats. Arguably the only two world-class cruiser-racer dinghies, in terms of both the extensive availability of top class racing and their suitability for serious cruising, are the Wayfarer and the GP14 ; of these the Wayfarer has the edge for cruising, once on the water, in part because she

4266-401: The main categories below. Dinghy designs are often referred to as "classes"; these classes are usually categorised as one design, open, or restricted. A more formal term for open is "Development Class". One design dinghies are supposed to be identical, though in reality this is not always the case. Only the most restrictive one design classes will restrict individual fittings. Then there becomes

4345-454: The pleasure of the owner and guests do not carry the passenger restriction. Yachts may be identified by flag—the country under which a yacht is registered. An industry publication categorizes superyachts by size, by speed, as "explorer" yachts, as sailing yachts, and classic yachts. Originally, all yachts were made of wood, using a wooden keel and ribs, clad with planks. These materials were supplanted with iron or steel in steam yachts. In

4424-415: The pleasure of the owner and guests, or by flag , the country under which it is registered. A superyacht (sometimes megayacht ) generally refers to any yacht (sail or power) longer than 131 ft (40 m). 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

4503-416: The provenance of outboard motors and racing boats , due to their power-to-weight ratios . Two engines add expense, but provide reliability and maneuverability over a single engine. Motor yachts in the 42-foot (13 m) range might have the following hull, horsepower, cruise speed, and hourly fuel consumption characteristics: Superyachts may employ multiple 9,000-horsepower (6,700 kW) diesels or

4582-576: The rig with the use of racks (wings) and trapeze. Examples are the 49er , an Olympic boat, 18 Footers (see below) and the advanced International 14 . High-performance dinghies are fast and powerful dinghies designed for racing around an Olympic triangle (Olympic Racing Course). Examples of such dinghies are the International Flying Dutchman , the International 505 , the Jet 14 , the Fireball ,

4661-407: The salon is likely to have convertible berths for its crew or passengers. Typically the salon includes a dining area, which may have a folding, built-in table. The salon is typically contiguous to the galley . A cruising yacht is likely to have a head (bathroom) with a marine toilet that discharges waste into a holding tank. Larger yachts may have additional staterooms and heads. There is typically

4740-543: The same calibre of performance as the above. However, in many cases they can still offer equally close competition, at the very highest standards, which for many racing helmsmen and crews is the most important consideration. They cover a wide range, and many are descended from Uffa Fox's seminal International 14. People often "travel" with their dinghies to international races in famous sailing spots such as Lake Garda in Italy. The Snipe International Class still stands as one of

4819-671: The same design. He assembled a group of potential owners who agreed to call the boat 'The Water Wag '. The Water Wag Club still prospers in Dún Laoghaire harbour, with racing each Wednesday evening during the Summer season. Towards the end of the 19th century people began to use these small boats for sport and recreational sailing, utilising the opportunities for leisure afforded by the Industrial Revolution . Larger privately used sailing boats had developed separately, and have resulted in

4898-431: The second oldest yacht club in the world, and the Lough Derg Yacht Club (est. 1835) (at Dromineer ). Sailing craft have until recently been just that: crafted by hand and eye. Each builder learned — and incorporated improvements in each successive boat. Yacht designers did the same, and the sport of yacht racing therefore evolved into a handicap sport as the boats were all different. One Design classes were created in

4977-445: The sheets, and more than one anchor to secure the boat in harbor. A cruising yacht's deck usually has safety line to protect the crew from falling overboard and a bow pulpit to facilitate handling the jib and the anchor. In temperate climates, the cockpit may have a canvas windshield with see-through panels, called a "dodger". Steering may be either by tiller or wheel. Cruising yachts have an auxiliary propulsion power unit to supplement

5056-555: The skipper is in charge or steering and the main sail depending on the boat, and the crew is in charge of the jib, the spinnaker, (which can only be flown while going downwind) and keeping the boat level Cruising dinghies are designed for leisure and family sailing and are usually more stable than high-performance dinghies. This is provided by a 'chined' (less rounded) hull, greater displacement, and proportionally smaller sail area. Some are specifically designed for longer passage-making, and/or for camping aboard. Examples of these include

5135-493: The strongest classes, after reaching the status of world's largest fleet of dinghies in July 1936. Other examples include the GP14 , Enterprise , Scorpion , Solo , Graduate , Firefly , Lark . A specialized subgroup is the Scow , which typically uses two bilgeboards instead of a centerboard , and may have two rudders . Many racing dinghies require two or more people to sail the boat,

5214-433: The subject, A Manual of Yacht and Boat Sailing , provided detailed information on selecting, equipping, sailing, seamanship, management of the paid crew, and racing such vessels. It included a brief section on steam yachts, the recirculating coil steam engine just having made such yachts efficient enough for leisure travel on the water. While sailing yachts continued to exist, the development of reliable power plants created

5293-470: The time. While trapezing can be helpful and increase speed, it can also be very dangerous if the crew is not wearing a quick-release harness or is inexperienced. The quick-release harness allows the crew to unstrap themselves quickly so as to not get forced under the boat if it were to capsize. Trapezing during a race first appeared in 1934, on the Amazon A Class Rater . Uffa Fox started building 14s in 1923, and

5372-552: The use of sails. Such power is inboard on the vessel and diesel, except for the smallest cruising boats, which may have an outboard gasoline motor . A 31-foot (9.4 m) sailboat might have a 13-horsepower (9.7 kW) engine, whereas a 55-foot (17 m) sailboat might have a 110-horsepower (82 kW) engine. Racing yachts emphasize performance over comfort. World Sailing recognizes eleven classes of racing yacht. High-performance rigs provide aerodynamic efficiency and hydrodynamically efficient hulls minimize drag through

5451-548: The variants of the Laser dinghy, a single-hander whose combination of simplicity, portability and performance has done much to advance dinghy racing and training. More modern dinghies like the Phil Morrison designed RS200 , RS400 , RS800 and RS Vareo Dinghies, the Musto Skiff , Splash and RS600 have also increased dinghy sailing participation around the UK. Two popular dinghies used in high school and college racing are

5530-470: The water and sideways motion. Racing yachts have a wide selection of weights and shapes of sail to accommodate different wind strengths and points of sail. A suite of sails on a racing yachts would include several weights of jib and spinnaker, plus a specialized storm jib and trysail (in place of the mainsail ). Performance yachts are likely to have full-battened kevlar or carbon-fiber mainsails. Underwater foils can become more specialized, starting with

5609-411: The water. This results in less friction because of reduced waterline length , reduced displacement (the amount of water needing to be pushed aside by the boat), and reduced ' wetted area '. The driving force provided by the sails has to overcome less resistance, and therefore speed increases dramatically. In 1928 Uffa Fox introduced planing to the English dinghy racing world in his International 14 boat,

5688-481: The waters of Burma, India, Mindanao and Japan. Anglo-Saxon royal pleg-scips (play ships) of the 8th-century featured ornamented bows and sterns and had the capability of cooking on board. The history of sailing yachts begins in Europe in the beginning of the 1600s with the building of a pleasure vessel for the son of King James I of England . While other monarchs used naval ships for transportation and conquest, James I

5767-746: Was built with a more powerful Gunther rig, and not the balanced lug as designed. The centre board as installed was of almost half the weight originally intended by F.C.M.G. (Ref) talk by Vincent Delany at LRYC February 2020 (/ref) All of this results in a dynamic dinghy. Walter Levinge: Creaghduff - 32 - 38 and all boats up to 117 not listed below. Merne: No.39. Charlie Ward: No.42. Patrick Keneavy: No. 50. Eddie Gray: Dún Laoghaire - No. 70. Tommy Gallagher: No.71. Lomax: No. 79, 81, 87, 89, 90, 94. Quigley: No. 99, 104, 105, 115, 116, 119, 120, 123 - 127, 138, 141, 143, 152. Jimmy Furey: No. 107, 112, 113, 121, 128 - 131, 139, 140, 144 - 150, 153 - 156. Erik Goodbody: No. 142, 151 The "SOD" or "Shannon" as

5846-483: Was designing them by 1925. He was to transform the class with the introduction of his first planing hull design, Avenger, in 1927. The construction and finish of his 14s was considered by many to be the ultimate in quality and craftsmanship, and Thunder and Lightning built in 1938 was no exception. The hull was built of two thin veneers; diagonal internally and fore and aft externally, and stiffened by tiny rock elm frames, all fastened with thousands of copper nails. His aim

5925-817: Was important to reduce the weight of coal carried. Steam engines remained the dominant source of power until the early 20th century, when advances in the design of the steam turbine , electric motors and internal combustion engines gradually resulted in the replacement of reciprocating (piston) steam engines. Large steam yachts were luxurious; their staff included a captain , engineer , and stewards, as well as deck hands. Nicolaus Otto and Gottlieb Daimler developed practical four-stroke gasoline engines, starting in 1876. Beginning in 1898 engines increased in horsepower from 25 horsepower (19 kW) to 500 brake horsepower (370 kW) by 1906. Some were destined for speedboats , other for motor yachts. Diesel power plants for boats were demonstrated in 1903. Diesels became

6004-690: Was predominantly built using stitch and glue, while the Enterprise and Heron is an example of a boat built using plywood on a timber frame. At the beginning of the 21st century, dinghy sailing is still a rapidly developing sport. It is losing its image of being expensive, time-consuming, and exclusive. This is because of the earlier work of pioneers such as Uffa Fox, and through the use of modern designs and techniques such as lighter hull materials (e.g., fibreglass and foam sandwich hull construction, which eliminate time-consuming maintenance and constant care that wooden hulls required, although they are rare and only

6083-627: Was reintroduced on the Osprey and Fiveohfive Class ( 505 ) in 1954 by John Westell and the Flying Dutchman class in the early 1960s. During the Second World War plywood had become a major building material for aircraft. After the war, plywood was adapted for building sailing dinghies. Two primary methods of construction were adopted: stitch and glue and timber-framed construction. Jack Holt designed many dinghies to be built by home handymen using these construction techniques. The Mirror Dinghy

6162-482: Was the first English monarch to commission the construction of a yacht—for his son Henry, Prince of Wales in the early 1600s. Pleasure vessels acquired the name yacht after the time of Charles II , who spent time exiled in Europe and visited the Netherlands, where a variety of jachten were already well developed as pleasure boats for the elite classes since the beginning of the 17th century. Upon his restoration to

6241-468: Was to achieve as light a construction as possible using the materials of the day – there was no carbon fibre or Kevlar then. Within a week of being launched, Thunder & Lightning won one of yachting's premier racing trophies, the Prince of Wales Cup, held that year at Falmouth. It was during this series that the boat's owners, Peter Scott (son of the famous Scott of the Antarctic ), and John Winter, used
