Hai (keelboat)
Hai (Finnish, lit. Shark) or Requin (French, lit. Shark) is a one-design, sloop-rigged keelboat designed in Finland. It was designed in 1930 by Finnish sailboat designer Gunnar Stenbäck as a cheap racing and cruising yacht suitable for mass production. It remains a popular small yacht in Finland and France. History In the 1920s, one-design yacht classes were relatively scarce and dominating form of yacht racing were various construction classes, which' boats were designed and built one at the time, and thus were quite expensive. Many Nordic top sailors and designers expressed concern about the future of the sport, and Stenbäck argued strongly that only in one-design class the costs could be kept suitably low. As a result, Hai design specified inexpensive materials (Northern pine and oak, iron ballast instead of lead) and relatively small sail area so that winches were not required. Keel was long and shallow, to ensure safety on rocky Baltic waters. Stenbäck presented his ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Hans Groop
Hans Groop, born 1932 in Vaasa is a Finnish yacht designer based in Helsinki. He has designed more than a hundred yachts and motorboats, the most famous being the H-boat, one of the most popular yacht classes in the world. Hans Groop has been a lifelong member of the HSS - a leading yachtclub for smaller keelboats in the Nordics. The club initiated the H-boat in 1967 in order to replace the popular but by then outmoded Hai-boat. Some of his other designs are the H-35, H-40, H-star, H-323, Targa 42, Targa 96, Finnsailor 34 and 29, Degerö 33, Joe 17, Joe 34, Netta ''Netta'' is a genus of diving ducks. The name is derived from Greek ''Netta'' "duck". Unlike other diving ducks, the ''Netta'' species are reluctant to dive, and feed more like dabbling ducks. These are gregarious ducks, mainly found on fres ..., IS 400, Artina 29 and Artina 33 as well as a lot of one-off boats.

1930s Sailboat Type Designs
Year 193 ( CXCIII) was a common year starting on Monday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Sosius and Ericius (or, less frequently, year 946 ''Ab urbe condita''). The denomination 193 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

Vehicles Introduced In 1930
A vehicle (from la, vehiculum) is a machine that transports people or cargo. Vehicles include wagons, bicycles, motor vehicles (motorcycles, cars, trucks, buses, mobility scooters for disabled people), railed vehicles (trains, trams), watercraft (ships, boats, underwater vehicles), amphibious vehicles (screw-propelled vehicles, hovercraft), aircraft (airplanes, helicopters, aerostats) and spacecraft.Halsey, William D. (Editorial Director): ''MacMillan Contemporary Dictionary'', page 1106. MacMillan Publishing, 1979. Land vehicles are classified broadly by what is used to apply steering and drive forces against the ground: wheeled, tracked, railed or skied. ISO 3833-1977 is the standard, also internationally used in legislation, for road vehicles types, terms and definitions. History * The oldest boats found by archaeological excavation are logboats, with the oldest logboat found, the Pesse canoe found in a bog in the Netherlands, being carbon dated to 8040 - 7510 B ...

Keelboats
A keelboat is a riverine cargo-capable working boat, or a small- to mid-sized recreational sailing yacht. The boats in the first category have shallow structural keels, and are nearly flat-bottomed and often used leeboards if forced in open water, while modern recreational keelboats have prominent fixed fin keels, and considerable draft. The two terms may draw from cognate words with different final meaning. A keep boat, keelboat, or keel-boat is a type of usually long, narrow cigar-shaped riverboat, or unsheltered water barge which is sometimes also called a poleboat—that is built about a slight keel and is designed as a boat built for the navigation of rivers, shallow lakes, and sometimes canals that were commonly used in America including use in great numbers by settlers making their way west in the century-plus of wide-open western American frontiers. They were also used extensively for transporting cargo to market, and for exploration and trading expeditions, for wa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Genoa (sail)
A genoa sail is a type of large jib or staysail that extends past the mast and so overlaps the main sail when viewed from the side, sometimes eliminating it. It was originally called an "overlapping jib" and later a genoa jib. It is used on single-masted sloops and twin-masted boats such as yawls and ketches. Its larger surface area increases the speed of the craft in light to moderate winds; in high wind, a smaller jib is usually substituted, and downwind a spinnaker may be used. Definition The term ''jib'' is the generic term for any of an assortment of ''headsails''. The term ''genoa'' (or genny) refers to a type of jib that is larger than the 100% foretriangle, which is the triangular area formed by the point at which the stay intersects the mast, and deck or bowsprit, and the line where the mast intersects deck at the rail. Colloquially the term is sometimes used interchangeably with ''jib''. A working jib is no larger than the 100% foretriangle. A genoa is larger, with ...

Glass-reinforced Plastic
Fiberglass (American English) or fibreglass (Commonwealth English) is a common type of fiber-reinforced plastic using glass fiber. The fibers may be randomly arranged, flattened into a sheet called a chopped strand mat, or woven into glass cloth. The plastic matrix may be a thermoset polymer matrix—most often based on thermosetting polymers such as epoxy, polyester resin, or vinyl ester resin—or a thermoplastic. Cheaper and more flexible than carbon fiber, it is stronger than many metals by weight, non-magnetic, non-conductive, transparent to electromagnetic radiation, can be molded into complex shapes, and is chemically inert under many circumstances. Applications include aircraft, boats, automobiles, bath tubs and enclosures, swimming pools, hot tubs, septic tanks, water tanks, roofing, pipes, cladding, orthopedic casts, surfboards, and external door skins. Other common names for fiberglass are glass-reinforced plastic (GRP), glass-fiber reinforced plastic (GFRP) or GFK ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
H-boat
The H-Boat is a strict One-Design#Sailing, one-design keelboat designed by Finn Hans Groop in 1967, with some minor modifications by Paul Bert Elvstrøm, Paul Elvstrøm in 1971. The boat gained international status in 1977. Since 1967 over 5000 hull (watercraft), hulls have been made, making it one of the most popular yacht classes in the world. The boat is mostly sailed and raced in Nordic countries and Central Europe, although there are a few boats in the United Kingdom, UK and the United States of America, US. The official race crew consists of three persons. Women and juniors are allowed to have a fourth crew member in competitions. The H-boat has sleeping bunks for up to four persons. As a cruising yacht, the boat is suitable for 2-5 persons. Major manufacturers of H-Boats have been Eagle Marine (Finland), Elvstrøm (Denmark), Scanboat (Åland), Hydrospeed (Finland), Artekno (Finland), Botnia Marin (Finland), O.L.

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 ...
