Sewn Boat
A sewn boat is a type of wooden boat which is clinker built with its planks sewn, stitched, tied, or bound together with tendons or flexible wood, such as roots and willow branches. Sewn boat construction techniques were used in many parts of the world prior to the development of metal fasteners, and continued to be used long after that time for small boats to reduce construction costs where metal fasteners were too expensive. Name and similar techniques Although well established, the ''sewn boat'' name is somewhat misleading since it suggests textile or leather skin construction, as often found in kayaks. Some have proposed to use ''laced boats'' ( Ge. ''geschnürte Boote'') instead. A modern plywood construction method that resembles sewn boats is the stitch and glue method; in this technique plywood panels are stitched together, often with wire, and the seams are reinforced with fiberglass composite; the stitching may then be removed or may remain in place.

Monocoque
Monocoque ( ), also called structural skin, is a structural system in which loads are supported by an object's external skin, in a manner similar to an egg shell. The word ''monocoque'' is a French term for "single shell". First used for boats, a true monocoque carries both tensile and compressive forces within the skin and can be recognised by the absence of a load-carrying internal frame. Few metal aircraft other than those with milled skins can strictly be regarded as pure monocoques, as they use a metal shell or sheeting reinforced with frames riveted to the skin, but most wooden aircraft are described as monocoques, even though they also incorporate frames. By contrast, a semi-monocoque is a hybrid combining a tensile stressed skin and a compressive structure made up of longerons and ribs or frames. Other semi-monocoques, not to be confused with true monocoques, include vehicle unibodies, which tend to be composites, and inflatable shells or balloon tanks, both of which ...

Dhow
Dhow ( ar, داو, translit=dāwa; mr, script=Latn, dāw) is the generic name of a number of traditional sailing vessels with one or more masts with settee or sometimes lateen sails, used in the Red Sea and Indian Ocean region. Typically sporting long thin hulls, dhows are trading vessels primarily used to carry heavy items, such as fruit, fresh water, or other heavy merchandise, along the coasts of Eastern Arabia, East Africa, Yemen and coastal South Asia (Pakistan, India, Bangladesh). Larger dhows have crews of approximately thirty, smaller ones typically around twelve. History The exact origins of the dhow are lost to history. Some claim that the sambuk, a type of dhow, may be derived from the Portuguese caravel. The dhow was the ship of trade used by the Swahili. It was a dhow that transported a giraffe to Chinese Emperor Yong Le's court, in 1414. Another source suggests the ship that carried the giraffe to China was part of a large Chinese fleet led by Zheng He. Ships ...

South Asia
South Asia is the southern subregion of Asia, which is defined in both geographical and ethno-cultural terms. The region consists of the countries of Afghanistan, Bangladesh, Bhutan, India, Maldives, Nepal, Pakistan, and Sri Lanka.;;;;;;;; Topographically, it is dominated by the Indian subcontinent and defined largely by the Indian Ocean on the south, and the Himalayas, Karakoram, and Pamir mountains on the north. The Amu Darya, which rises north of the Hindu Kush, forms part of the northwestern border. On land (clockwise), South Asia is bounded by Western Asia, Central Asia, East Asia, and Southeast Asia. The South Asian Association for Regional Cooperation (SAARC) is an economic cooperation organization in the region which was established in 1985 and includes all eight nations comprising South Asia. South Asia covers about , which is 11.71% of the Asian continent or 3.5% of the world's land surface area. The population of South Asia is about 1.9 billion or about one- ...

Middle East
The Middle East ( ar, الشرق الأوسط, ISO 233: ) is a geopolitical region commonly encompassing Arabian Peninsula, Arabia (including the Arabian Peninsula and Bahrain), Anatolia, Asia Minor (Asian part of Turkey except Hatay Province), East Thrace (European part of Turkey), Egypt, Iran, the Levant (including Syria (region), Ash-Shām and Cyprus), Mesopotamia (modern-day Iraq), and the Socotra Governorate, Socotra Archipelago (a part of Yemen). The term came into widespread usage as a replacement of the term Near East (as opposed to the Far East) beginning in the early 20th century. The term "Middle East" has led to some confusion over its changing definitions, and has been viewed by some to be discriminatory or too Eurocentrism, Eurocentric. The region includes the vast majority of the territories included in the closely associated definition of Western Asia (including Iran), but without the South Caucasus, and additionally includes all of Egypt (not just the Sina ...

Lashed-lug
Lashed-lug boats are ancient boat-building techniques of the Austronesian peoples. It is characterized by the use of sewn holes and later dowels ("treenails") to stitch planks edge-to-edge onto a dugout keel and solid carved wood pieces that form the caps for the prow and stern. The planks are further lashed together and to ribs with fiber ropes wrapped around protruding carved lugs on the inside surfaces. Unlike carvel construction, the shell of the boat is created first, prior to being fastened to the ribs. The seams between planks are also sealed with absorbent tapa bark and fiber that expands when wet or caulked with resin-based preparations. Lashed-lug construction techniques are found in all the traditional boats of Maritime Southeast Asia, Melanesia, Madagascar, Micronesia, and Polynesia, and was one of the early maritime boat-building techniques that allowed the rapid expansion of the Austronesian peoples throughout the islands of the Indo-Pacific starting at 3000 to 1500 ...

Indo-Pacific
The Indo-Pacific is a vast biogeographic region of Earth. In a narrow sense, sometimes known as the Indo-West Pacific or Indo-Pacific Asia, it comprises the tropical waters of the Indian Ocean, the western and central Pacific Ocean, and the seas connecting the two in the general area of Indonesia. It does not include the temperate and polar regions of the Indian and Pacific oceans, nor the Tropical Eastern Pacific, along the Pacific coast of the Americas, which is also a distinct marine realm. The term is especially useful in marine biology, ichthyology, and similar fields, since many marine habitats are continuously connected from Madagascar to Japan and Oceania, and a number of species occur over that range, but are not found in the Atlantic Ocean. The region has an exceptionally high species richness, with the world's highest species richness being found in at its heart in the Coral Triangle, and a remarkable gradient of decreasing species richness radiating outward in al ...

Proa
Proas are various types of multi-hull outrigger sailboats of the Austronesian peoples. The terms were used for native Austronesian ships in European records during the Colonial era indiscriminately, and thus can confusingly refer to the double-ended single-outrigger boats of Oceania, the double-outrigger boats of Island Southeast Asia, and sometimes ships with no outriggers or sails at all. In its most common usage, the term ''proa'' refers to the Pacific proas which consist of two (usually) unequal-length parallel hulls. It is sailed so that one hull is kept to windward, and the other to leeward. It is double-ended, since it needs to " shunt" to reverse direction when tacking. It is most famously used for the ''sakman'' ships of the Chamorro people of the Northern Marianas, which were known as the "flying proas" for their remarkable speed. In Island Southeast Asia, the term ''proa'' may also sometimes be used, but the terms perahu, prau, prahu, paraw and prow are more ...

Karelia
Karelia ( Karelian and fi, Karjala, ; rus, Каре́лия, links=y, r=Karélija, p=kɐˈrʲelʲɪjə, historically ''Korjela''; sv, Karelen), the land of the Karelian people, is an area in Northern Europe of historical significance for Russia (including the Soviet era), Finland, and Sweden. It is currently divided between northwestern Russia (specifically the federal subjects of the Republic of Karelia and Leningrad Oblast) and Finland (the regions of South Karelia, North Karelia, and the eastern portion of modern-day Kymenlaakso).

The Republic of Karelia is a Russian federal subject, including East Karelia with a chiefly Russian Orthodox population. Within present-da ...
