Canoe Sailing
Canoe sailing refers to the practice of fitting an Austronesian outrigger or Western canoe with sails. Austronesian sailing canoes The outrigger canoe was one of the key technological innovations of the Austronesian peoples. Although there is little archeological evidence due to perishable building materials, comparative reconstructions indicate that Austronesians already had the distinctive outrigger and crab claw sail technology from at least 2000 BCE. These boats (as well as derivative technologies like the catamaran) enabled them to colonize the islands of Southeast Asia and then later on to Madagascar, the Pacific Islands, and New Zealand. Outrigger canoes like the '' va'a'', '' paraw'', ''jukung'', '' vinta'', and '' proa'' are still used today by traditional fishermen and traders in most of Southeast Asia and Madagascar, and in parts of Oceania. They are constructed from traditional materials, though most incorporate motor engines instead of a sail. In other regions l ...

Austronesian People
The Austronesian peoples, sometimes referred to as Austronesian-speaking peoples, are a large group of peoples in Taiwan, Maritime Southeast Asia, Micronesia, coastal New Guinea, Island Melanesia, Polynesia, and Madagascar that speak Austronesian languages. They also include indigenous ethnic minorities in Vietnam, Cambodia, Myanmar, Thailand, Hainan, the Comoros, and the Torres Strait Islands. The nations and territories predominantly populated by Austronesian-speaking peoples are sometimes known collectively as Austronesia. Based on the current scientific consensus, they originated from a prehistoric seaborne migration, known as the Austronesian expansion, from pre- Han Taiwan, at around 1500 to 1000 BCE. Austronesians reached the northernmost Philippines, specifically the Batanes Islands, by around 2200 BCE. Austronesians used sails some time before 2000 BCE. In conjunction with their use of other maritime technologies (notably catamarans, outrigger boats, la ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vinta
The vinta is a traditional outrigger boat from the Philippine island of Mindanao. The boats are made by Sama-Bajau, Tausug and Yakan peoples living in the Sulu Archipelago, Zamboanga peninsula, and southern Mindanao. Vinta are characterized by their colorful rectangular lug sails (''bukay'') and bifurcated prows and sterns, which resemble the gaping mouth of a crocodile. Vinta are used as fishing vessels, cargo ships, and houseboats. Smaller undecorated versions of the vinta used for fishing are known as tondaan. The name "vinta" is predominantly used in Zamboanga, Basilan, and other parts of mainland Mindanao. It is also known as pilang or pelang among the Sama-Bajau of the Tawi-Tawi islands; dapang or depang among the Tausug in Sulu; and balanda or binta in Yakan in Basilan. It can also be generically referred to as '' lepa-lepa'', ''sakayan'', or '' bangka'', which are native names for small outrigger vessels. Description The vinta has a deep and narrow hull formed ...

Rob Roy Canoe
John MacGregor (24 January 1825 Gravesend – 16 July 1892 Boscombe, Bournemouth), nicknamed ''Rob Roy'' after a renowned relative, was an English explorer, travel writer and philanthropist. He is generally credited with the development of the first sailing canoes and with popularising canoeing as a sport in Europe and the United States. He founded the British Royal Canoe Club (RCC) in 1866 becoming its first Captain and also founded American Canoe Association in 1880. MacGregor worked as a barrister in London, and was an accomplished artist who drew all the illustrations in his travel books. Early life MacGregor was born in Gravesend to Major Duncan MacGregor, a Scottish soldier, and Elizabeth, the daughter of Sir William Dick, Baronet of Prestonfield. When he was five weeks old, he was amongst the survivors of the sinking of the ''Kent''. His schooling followed his father's postings, and he attended The King's School in Canterbury and Trinity College in Dublin. He g ...

Ethnohistory
Ethnohistory is the study of cultures and indigenous peoples customs by examining historical records as well as other sources of information on their lives and history. It is also the study of the history of various ethnic groups that may or may not still exist. The term is most commonly used in writing about the history of the Americas. Ethnohistory uses both historical and ethnographic data as its foundation. Its historical methods and materials go beyond the standard use of documents and manuscripts. Practitioners recognize the use of such source material as maps, music, paintings, photography, folklore, oral tradition, site exploration, archaeological materials, museum collections, enduring customs, language, and placenames. Historical development Scholars studying the history of Mexico's indigenous have a long tradition, dating back to the colonial era; they used alphabetic texts and other sources to write the history of Mexico's indigenous peoples.

Kevlar
Kevlar (para-aramid) is a strong, heat-resistant synthetic fiber, related to other aramids such as Nomex and Technora. Developed by Stephanie Kwolek at DuPont in 1965, the high-strength material was first used commercially in the early 1970s as a replacement for steel in racing tires. It is typically spun into ropes or fabric sheets that can be used as such, or as an ingredient in composite material components. Kevlar has many applications, ranging from bicycle tires and racing sails to bulletproof vests, all due to its high tensile strength-to-weight ratio; by this measure it is five times stronger than steel. It is also used to make modern marching drumheads that withstand high impact; and for mooring lines and other underwater applications. A similar fiber called Twaron with the same chemical structure was developed by Akzo in the 1970s; commercial production started in 1986, and Twaron is now manufactured by Teijin.

Dacron
Polyethylene terephthalate (or poly(ethylene terephthalate), PET, PETE, or the obsolete PETP or PET-P), is the most common thermoplastic polymer resin of the polyester family and is used in fibres for clothing, containers for liquids and foods, and thermoforming for manufacturing, and in combination with glass fibre for engineering resins. In 2016, annual production of PET was 56 million tons. The biggest application is in fibres (in excess of 60%), with bottle production accounting for about 30% of global demand. In the context of textile applications, PET is referred to by its common name, polyester, whereas the acronym ''PET'' is generally used in relation to packaging. Polyester makes up about 18% of world polymer production and is the fourth-most-produced polymer after polyethylene (PE), polypropylene (PP) and polyvinyl chloride (PVC). PET consists of repeating (C10H8O4) units. PET is commonly recycled, and has the digit 1 (♳) as its resin identification code (RI ...

Carbon Fiber-reinforced Polymer
Carbon fiber-reinforced polymers (American English), carbon-fibre-reinforced polymers (Commonwealth English), carbon-fiber-reinforced plastics, carbon-fiber reinforced-thermoplastic (CFRP, CRP, CFRTP), also known as carbon fiber, carbon composite, or just carbon, are extremely strong and light fiber-reinforced plastics that contain carbon fibers. CFRPs can be expensive to produce, but are commonly used wherever high strength-to-weight ratio and stiffness (rigidity) are required, such as aerospace, superstructures of ships, automotive, civil engineering, sports equipment, and an increasing number of consumer and technical applications. The binding polymer is often a thermoset resin such as epoxy, but other thermoset or thermoplastic polymers, such as polyester, vinyl ester, or nylon, are sometimes used. The properties of the final CFRP product can be affected by the type of additives introduced to the binding matrix (resin). The most common additive is silica, but other additi ...

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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sailing (sport)
The sport of sailing involves a variety of competitive sailing formats that are sanctioned through various sailing federations and yacht clubs. Racing disciplines include matches within a fleet of sailing craft, between a pair thereof or among teams. Additionally, there are specialized competitions that include setting speed records. Racing formats include both closed courses and point-to-point contests; they may be in sheltered waters, coast-wise or on the open ocean. Most competitions are held within defined classes or ratings that either entail one type of sailing craft to ensure a contest primarily of skill or rating the sailing craft to create classifications or Handicapping, handicaps. On water, a sailing competition among multiple vessels is a regatta, which usually consists of multiple individual races, where the boat crew that performs best in over the series of races is the overall winner. There is a broad variety of kinds of races and sailboats used for racing from Yac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
