Logboat
A dugout canoe or simply dugout is a boat made from a hollowed-out tree. Other names for this type of boat are logboat and monoxylon. ''Monoxylon'' (''μονόξυλον'') (pl: ''monoxyla'') is Greek''mono-'' (single) + '' ξύλον xylon'' (tree)and is mostly used in classic Greek texts. In German, they are called Einbaum ("one tree" in English). Some, but not all, pirogues are also constructed in this manner. Dugouts are the oldest boat type archaeologists have found, dating back about 8,000 years to the Neolithic Stone Age. This is probably because they are made of massive pieces of wood, which tend to preserve better than others, such as bark canoes. Construction Construction of a dugout begins with the selection of a log of suitable dimensions. Sufficient wood must be removed to make the vessel relatively light in weight and buoyant, yet still strong enough to support the crew and cargo. Specific types of wood were often preferred based on their strength, durability, a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Boats At The Shore Of The Malawi Lake
A boat is a watercraft of a large range of types and sizes, but generally smaller than a ship, which is distinguished by its larger size or capacity, its shape, or its ability to carry boats. Small boats are typically used on inland waterways such as rivers and lakes, or in protected coastal areas. However, some boats (such as whaleboats) were intended for offshore use. In modern Navy, naval terms, a boat is a vessel small enough to be carried aboard a ship. Boats vary in proportion and construction methods with their intended purpose, available materials, or local traditions. Canoes have been used since prehistoric times and remain in use throughout the world for transportation, fishing, and sport. Fishing boats vary widely in style partly to match local conditions. Pleasure boat, Pleasure craft used in boating, recreational boating include ski boats, Pontoon (boat), pontoon boats, and sailboats. House boats may be used for vacationing or long-term residence.

Canoe
A canoe is a lightweight, narrow watercraft, water vessel, typically pointed at both ends and open on top, propelled by one or more seated or kneeling paddlers facing the direction of travel and using paddles. In British English, the term ''canoe'' can also refer to a kayak, whereas canoes are then called Canadian (canoe), Canadian or open canoes to distinguish them from kayaks. However, for official competition purposes, the American distinction between a kayak and a canoe is almost always adopted. At the Olympics, both conventions are used: under the umbrella terms Canoe Slalom and Canoe Sprint, there are separate events for canoes and kayaks. Culture Canoes were developed in cultures all over the world, including some designed for use with sails or outriggers. Until the mid-19th century, the canoe was an important means of transport for exploration and trade, and in some places is still used as such, sometimes with the addition of an outboard motor.

Trade
Trade involves the transfer of goods and services from one person or entity to another, often in exchange for money. Economists refer to a system or network that allows trade as a market. Traders generally negotiate through a medium of credit or exchange, such as money. Though some economists characterize barter (i.e. trading things without the use of money) as an early form of trade, money was invented before written history began. Consequently, any story of how money first developed is mostly based on conjecture and logical inference. Letters of credit, paper money, and non-physical money have greatly simplified and promoted trade as buying can be separated from selling, or earning. Trade between two traders is called bilateral trade, while trade involving more than two traders is called multilateral trade. In one modern view, trade exists due to specialization and the division of labor, a predominant form of economic activity in which individuals and groups ...

Niger River
The Niger River ( ; ) is the main river of West Africa, extending about . Its drainage basin is in area. Its source is in the Guinea Highlands in south-eastern Guinea near the Sierra Leone border. It runs in a crescent shape through Mali, Niger, on the border with Benin and then through Nigeria, discharging through a massive River delta, delta, known as the Niger Delta, into the Gulf of Guinea in the Atlantic Ocean. The Niger is the third-longest river in Africa, exceeded by the Nile and the Congo River. Its main tributary is the Benue River. Etymology The Niger has different names in the different languages of the region: * Fula language, Fula: ''Maayo Jaaliba'' * Manding languages, Manding: ''Jeliba'' or ''Joliba'' "great river" * Tuareg languages, Tuareg: ''Eġərəw n-Igərǝwăn'' "river of rivers" * Songhay languages, Songhay: ''Isa'' "the river" * Zarma language, Zarma: ''Isa Beeri'' "great river" * Hausa language, Hausa: ''Kwara'' *Nupe language, Nupe: ''Èdù'' ...

Tributaries
A tributary, or an ''affluent'', is a stream or river that flows into a larger stream ('' main stem'' or ''"parent"''), river, or a lake. A tributary does not flow directly into a sea or ocean. Tributaries, and the main stem river into which they flow, drain the surrounding drainage basin of its surface water and groundwater, leading the water out into an ocean, another river, or into an endorheic basin. The Irtysh is a chief tributary of the Ob river and is also the longest tributary river in the world with a length of . The Madeira River is the largest tributary river by volume in the world with an average discharge of . A confluence, where two or more bodies of water meet, usually refers to the joining of tributaries. The opposite to a tributary is a distributary, a river or stream that branches off from and flows away from the main stream. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Makoro
A mokoro (also spelled ''makoro'', Setswana-English-Setswana Dictionary, Macmillan Botswana, 4th edition) is a type of dugout canoe commonly used in the Okavango Delta and on the Chobe River in Botswana. It is propelled through the shallow waters of the delta or the river by standing in the stern and pushing against the riverbed with a pole, in the same manner as punting. The plural in Setswana is ''mekoro''. Mokoro are traditionally made by digging out the trunk of a large straight tree, such as ebony and African sausage tree. Modern mokoros, however, are increasingly made of fiberglass, one of the advantages of which is the preservation of large trees. Mokoro safaris are a popular way for tourists to visit the delta and river, much of which is located in protected areas, but the boats are still a practical means of transport for local residents to use to move around the swamp. The boats are very vulnerable to attack by hippopotamus, which can overturn them with ease. Hippop ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Paddling
Paddling, in regard to waterborne transport, is the act of propelling a human-powered watercraft using at least one hand-held paddle. The paddle, which consists of one or two blades joined to a shaft, is also used to steer the vessel via generating a difference in propulsion between the two broadside (naval), sides of the watercraft. The paddle is not connected to the boat, unlike in rowing where the oar is attached to the boat. In paddling sports such as canoeing and kayaking, the characteristics that are most important include "dynamic balance, core stability, pulling power, speed, endurance, stature, and rhythm". Canoeing Canoeing is the activity of paddling a canoe for leisure, navigation or exploration. In America the term refers exclusively to using one or more single blades or paddles to propel a canoe. In the United Kingdom and some other countries in Europe however, canoeing is also used to refer to kayaking, and canoeing is then often called ''Canadian (canoe), Canadia ...

Watercraft
A watercraft or waterborne vessel is any vehicle designed for travel across or through water bodies, such as a boat, ship, hovercraft, submersible or submarine. Types Historically, watercraft have been divided into two main categories. *Rafts, which gain their buoyancy from the fastening together of components that are each buoyant in their own right. Generally, a raft is a "flow through" structure, whose users would have difficulty keeping dry as it passes through waves. Consequently, apart from short journeys (such as a river crossing), their use is confined to warmer regions (roughly 40° N to 40° S). Outside this area, use of rafts at sea is impracticable due to the risks of exposure to the crew. *Boats and ships, which float by having the submergeable part of their structure exclude water with a waterproof surface, so creating a space that contains air, as well as cargo, passengers, crew, etc. In total, this structure weighs less than the water that would occupy the sa ...

Goods
In economics, goods are anything that is good, usually in the sense that it provides welfare or utility to someone. Alan V. Deardorff, 2006. ''Terms Of Trade: Glossary of International Economics'', World Scientific. Online version: Deardorffs' Glossary of International Economics"good" an Goods can be contrasted with bads, i.e. things that provide negative value for users, like chores or waste. A bad lowers a consumer's overall welfare. Economics focuses on the study of economic goods, i.e. goods that are scarce; in other words, producing the good requires expending effort or resources. Economic goods contrast with free goods such as air, for which there is an unlimited supply.Samuelson, P. Anthony., Samuelson, W. (1980). Economics. 11th ed. / New York: McGraw-Hill. Goods are the result of the Secondary sector of the economy which involves the transformation of raw materials or intermediate goods into goods.
