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 Greekmono- (single) + ξύλον xylon (tree)and is mostly used in classic Greek texts. In German, they are called Einbaum ("one tree" in English). Some 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.1000 Inventions and Discoveries, by Roger Bridgman 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, and density. The shape of the boat is then fashioned to minimize drag, with sharp ends at the bow and stern.

First, the bark is removed from the exterior. Before the appearance of metal tools, dugouts were hollowed out using controlled fires. The burnt wood was then removed using an adze. Another method using tools is to chop out parallel notches across the interior span of the wood, then split out and remove the wood from between the notches. Once hollowed out, the interior was dressed and smoothed out with a knife or adze.

More primitive designs keep the tree's original dimensions, with a round bottom. However, it is possible to carefully steam the sides of the hollow log until they are pliable, then bend to create a more flat-bottomed "boat" shape with a wider beam in the center.

For travel in the rougher waters of the ocean, dugouts can be fitted with outriggers. One or two smaller logs are mounted parallel to the main hull by long poles. In the case of two outriggers, one is mounted on either side of the hull.

Africa The Dufuna canoe from Nigeria is an 8000-year-old dugout, the oldest boat discovered in Africa, and is, by varying accounts, the second or third-oldest ship worldwide. The well-watered tropical rainforest and woodland regions of sub-Saharan Africa provide both the waterways and the trees for dugout canoes, which are commonplace from the Limpopo River basin in the south through East and Central Africa and across to West Africa. African teak is the timber favoured for their construction, though this comprises a number of different species, and is in short supply in some areas. Dugouts are paddled across deep lakes and rivers or punted through channels in swamps (see makoro or mtumbwi) or in shallow areas, and are used for transport, fishing, and hunting, including, in the past, the very dangerous hunting of hippopotamus. Dugouts are called pirogues in Francophone areas of Africa.

A Nok sculpture portrays two individuals, along with their goods, in a dugout canoe. Both of the anthropomorphic figures in the watercraft are paddling. The Nok terracotta depiction of a dugout canoe may indicate that Nok people utilized dugout canoes to transport cargo, along tributaries (e.g., Gurara River) of the Niger River, and exchanged them in a regional trade network. The Nok terracotta depiction of a figure with a seashell on its head may indicate that the span of these riverine trade routes may have extended to the Atlantic Coast. In the maritime history of Africa, there is the earlier Dufuna canoe, which was constructed approximately 8000 years ago in the northern region of Nigeria; as the second earliest form of water vessel known in Sub-Saharan Africa, the Nok terracotta depiction of a dugout canoe was created in the central region of Nigeria during the first millennium BCE.

The engineering and methodology (e.g., cultural valuations, use of iron tools) used in the construction of West African dugout canoes (e.g., rounded point sterns and pointed bows with 15° - 50° angle above water surface, increased stability via partly rounded or flat base, v-shaped hull, shallow draft for sailing water depths less than one foot, occasionally spanning more than one hundred feet in length) contributed to the capability of the canoes to be able to persist and navigate throughout the interconnected river system that connected the Benue River, Gambia River, Niger River, and Senegal River as well as Lake Chad; this river system connected diverse sources of water (e.g., lakes, rivers, seas, streams) and ecological zones (e.g., Sahara, Sahel, Savanna), and allowed for the transport of people, information, and economic goods along riverine trade networks that connect various locations (e.g., Bamako, Djenne, Gao, Mopti, Segou, Timbuktu) throughout West Africa and North Africa. The knowledge and understanding (e.g., hydrography, marine geography, how canoe navigation is affected by the depth of the water, tides in the ocean, currents, and winds) of West African canoers facilitated the skillful navigation of various channels of the regional river system, while engaging in activities such as trade and fishing. The construction schema for West African dugout canoes were also used among canoes in the Americas constructed by the African diaspora. The sacredness of canoe-making is expressed in a proverb from Senegambia: "The blood of kings and the tears of the canoe-maker are sacred things which must not touch the ground." In addition to possessing economic value, West African dugout canoes also possessed a sociocultural and psychospiritual value.

In 1735 CE, John Atkins observed: "Canoos are what used through the whole Coast for transporting Men and Goods." European rowboats, which frequently capsized, were able to be outmaneuvered and outperformed in terms of speed by West African dugout canoes. Barbot stated, regarding West African canoers and West African dugout canoes, the "speed with which these people generally make these boats travel is beyond belief." Alvise da Cadamosto also observed how "effortlessly" Portuguese caravels were outperformed by Gambian dugout canoes. The skill of Kru canoers to be able to navigate the challenging conditions of the sea was also observed by Charles Thomas.

Amid the 1590s CE, Komenda and Takoradi in Ghana served as production areas for dugout canoes made by the Ahanta people. By 1679 CE, Barbot observed Takoradi to be "a major canoe-producing center, crafting dugouts capable of carrying up to eight tons." Between the 17th century CE and 18th century CE, a production area and/or marketplace of dugout canoes was in Shama, which later became only a marketplace on Supome Island. Amid the 1660s CE, in addition to other local canoers manufacturing dugout canoes, the Fetu people were observed by Muller as having bought dugout canoes that were made by the Ahanta people.

West Africans (e.g., Ghana, Ivory Coast, Liberia, Senegal) and western Central Africans (e.g., Cameroon) independently developed the skill of surfing. Amid the 1640s CE, Michael Hemmersam provided an account of surfing in the Gold Coast: "the parents 'tie their children to boards and throw them into the water. In 1679 CE, Barbot provided an account of surfing among Elmina children in Ghana: "children at Elmina learned "to swim, on bits of boards, or small bundles of rushes, fasten'd under their stomachs, which is a good diversion to the spectators." James Alexander provided an account of surfing in Accra, Ghana in 1834 CE: "From the beach, meanwhile, might be seen boys swimming into the sea, with light boards under their stomachs. They waited for a surf; and came rolling like a cloud on top of it. But I was told that sharks occasionally dart in behind the rocks and 'yam' them." Thomas Hutchinson provided an account of surfing in southern Cameroon in 1861: "Fishermen rode small dugouts 'no more than six feet in length, fourteen to sixteen inches in width, and from four to six inches in depth.

Asia

An 8000-year-old dugout canoe was found by archaeologists in Kuahuqiao, Zhejiang Province, in east China.Leping Jiang & Li Liu, The discovery of an 8000-year-old dugout canoe at Kuahuqiao in the Lower Yangzi River, China. 2005 antiquity.ac.uk This is the earliest canoe found in Asia.

The Moken, an ethnic group that lives in Myanmar's Mergui Archipelago and the north of Thailand as sea nomads, still builds and uses dugout canoes. According to the Moken's accounts of their people's origin, a mythical queen punished the forbidden love of their ancestral forefather for his sister-in-law by banishing him and his descendants to life on sea in dugout canoes with indentations fore and aft ("a mouth that eats and a rear that defecates"), symbolizing the unending cycle of ingestion, digestion and evacuation.

A centuries-old unfinished dugout boat, a big banca (five tons, measuring by by ) was accidentally retrieved in November 2010 by Mayor Ricardo Revita at Barangay Casanicolasan, Rosales, Pangasinan, Philippines, in Lagasit River, near Agno River. It is now on display in front of the Municipal Town Hall.

Dugout canoes are one of the most used traditional fishing vessels in India. Forest Department at Kolleru Lake held various contests with the dugout canoe among local fishing communities. In an era where the traditional canoe faces extinction, the boat race saw 22 participants. They also noted that within two decades, there were over 1,000 dugout canoes employed for fishing in the lake. Now, their count has dwindled to less than a hundred.

Europe

In ancient Europe many dugouts were made from linden wood, for several reasons. First, linden trees were abundant in the Paleolithic after the melting of the Weichselian glaciation and readily available. Secondly, linden grew to be one of the tallest trees in the forests of the time, making it easier to build longer boats. Linden wood also lends itself well to carving and doesn't split or crack easily. It is also lighter than most other tree types in European old-growth forests, and for this reason, boats made from linden wood have a better cargo capacity and are easier to carry.

The Pesse canoe, found in the Netherlands, is a dugout which is believed to be the world's oldest boat, carbon dated to between 8040 BCE and 7510 BCE. Other dugouts discovered in the Netherlands include two in the province of North Holland: in 2003, near Uitgeest, dated at 617-600 BC; and in 2007, near Den Oever, dated at 3300-3000 BC.

Dugouts have also been found in Germany. In German, the craft is known as Einbaum (one-tree). In the old Hanseatic town of Stralsund, three log-boats were excavated in 2002. Two of the boats were around 7,000 years old and are the oldest boats found in the Baltic area. The third boat (6,000 years old) was long and holds the record as the longest dugout in the region. The finds have partly deteriorated due to poor storage conditions.Kaute, P., G. Schindler & H. Lobke. 2004. "Der endmesolithisch/fruhneolithische Fundplatz Stralsund-Mischwasserspeicher--Zeugnisse fruher Bootsbautechnologie an der Ostseekuste Mecklenburg-Vorpommerns. Bodendenkmalpflege in Mecklenburg-Vorpommern" (52: 221-41)

In 1991, remains of a linden wood log-boat of nearly were found at Männedorf-Strandbad in Switzerland at Lake Zürich. The boat has since been dated to be 6,500 years old.

In 1902 an oak logboat over long and wide, was found at Addergoole Bog, Lurgan, County Galway, Ireland, and delivered to the National Museum of Ireland. The Lurgan boat radiocarbon date was 3940 ± 25 BP. The boat has holes suggesting that it had an outrigger or was joined to another boat.
