Dugout canoe

A dugout canoe or simply dugout is a boat made from a hollowed tree trunk. 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 Germany they are called einbaum ("one tree" in English). Some, but not all, pirogues are also constructed in this manner.


Dugouts are the oldest boats 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, e.g., bark canoes. Along with bark canoe and hide kayak, dugout boats were also used by indigenous peoples of the Americas.


Construction of a dugout begins with the selection of a log of suitable dimensions. Sufficient wood needed to 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 centre.

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.


The Dufuna canoe from Nigeria is an 8000-year-old dugout, the oldest boat discovered in Africa, and the third-oldest 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 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 8000-year-old dugout canoe was found by archaeologists in Kuahuqiao, Zhejiang Province, in east China. 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 8 by 2 by 1.5 meters) was accidentally retrieved on 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.


Here many dugouts were made from linden wood, for several reasons. First of all it was abundant in the Stone Age after the melting of the Weichselian glaciation of the last iceage and readily available. Secondly it grew to be one of the tallest trees in the forests of these days, making it easier to build longer boats. Thirdly linden wood lends itself well to carving and it doesn't split or crack so easily. Fourth it is lighter and therefore have a better cargo capacity and is easier to carry, than most other tree types from the European old-growth forests.

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.

Dugouts have also been found in Germany. In German, the craft are 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 thus the oldest boats of the Baltic area in existence. The third boat (6,000 years old) was 12 meters long and therefore holds the record as the longest dugout in the region. The finds have partly deteriorated due to poor storage conditions.

In 1991, remains of a linden wood log-boat of nearly 6 meters, 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 log boat, (dugout) over 15m long and 1m 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.

In 2012, at Parc Glyndwr, Monmouth, Monmouthshire, Wales, UK, an excavation by Monmouth Archeological Society, revealed three ditches suggesting a Neolithic dugout trimaran of similar length to the Lurgan log boat, carbon dated 3700+/-35 BP.

De Administrando Imperio details how the Slavs built monoxyla that they sold to Rus' in Kiev. These ships were then used against the Byzantine Empire during the Rus'–Byzantine Wars of the 9th and 10th centuries. They used dugouts to attack Constantinople and to withdraw into their lands with bewildering speed and mobility. Hence, the name of Δρομίται ("people on the run") applied to the Rus in some Byzantine sources. The monoxyla were often accompanied by larger galleys, that served as command and control centres. Each Slavic dugout could hold from 40 to 70 warriors.

The Cossacks of the Zaporozhian Host were also renowned for their artful use of dugouts, which issued from the Dnieper to raid the shores of the Black Sea in the 16th and 17th centuries. Using small, shallow-draft, and highly maneuverable galleys known as chaiky, they moved swiftly across the Black Sea. According to the Cossacks' own records, these vessels, carrying a 50 to 70 man crew, could reach the coast of Anatolia from the mouth of the Dnieper River in forty hours.

More than 40 pre-historic log-boats have been found in the Czech Republic. The latest discovery was in 1999 of a 10 m long log-boat in Mohelnice (Šumperk District). It was cut out of a single oak log and have a width of 1.05 m. The log-boat have been dated to around 1.000 BC and is kept at the 'Mohelnice Muzeum' (Museum of National History). Geographically, Czech logboat sites and remains are clustered along the Elbe and Morava Rivers.

Poland is known for the socalled Lewin-type log-boats, found a Lewin Brzeski, Koźle and Roszowicki Las accordingly. These boats, are characterized by square or trapezoidal cross-section, rectangular hull-ends and low height of the sides in relation to vessel length. In addition, nearly all the Lewin-type boats have a single hole in the bow and two at the stern. The low height is a result of the parent log being split lengthwise in half, in order to obtain two identical timbers from a single trunk. The advantage lies in the resulting identical twin hulls, which are then joined to form a double-hulled raft. The paired hulls were joined by transverse poles, which did not go through the holes in the platform ends but were fastened to the top walls or in special grooves at the hull ends. These vessels were typically 7–12 m in length, and the largest of them could carry up to 1.5 tons of cargo because of the special design. The Lewin type logboats are usually associated with the Przeworsk culture in the early centuries AD.

Many pre-historic dugout boats have been found in Scandinavia. These boats were used for transport on calmer bodies of water, fishing and maybe occasionally for whaling and sealing. Dugouts require no metal parts, and were common amongst the Stone Age people in Northern Europe until large trees suitable for making this type of watercraft became scarce. Length was limited to the size of trees in the old-growth forests—up to 12 metres (39 ft) in length. In Denmark in 2001 and some years prior to that, a few dugout canoes of linden wood, was unearthed in a large scale archaeological excavation project in Egådalen, just north of Aarhus. They have been carbon dated to the years 5210-4910 BCE and they are the oldest known boats in Northern Europe.

Later models increased freeboard (and seaworthiness) by lashing additional boards to the side of the boat. Eventually, the dugout portion was reduced to a solid keel, and the lashed boards on the sides became a Lapstrake hull.

In the United Kingdom, two log boats were discovered in Newport, Shropshire and are now on display at Harper Adams University Newport. The Iron Age residents of Great Britain, were known to have used logboats for fishing and basic trade. In 1964, a logboat was uncovered in Poole Harbour, Dorset. The Poole Logboat dated to 300 BC, was large enough to accommodate 18 people and was constructed from a giant oak tree. It is currently located in the Poole Museum. An even older logboat (the Hanson log boat) was unearthed in 1998 in Shardlow south of Derby. It has been dated to the Bronze Ages around 1.500 BC and is now exhibited at Derby Museum and Art Gallery. There was another pre-historic boat at the same location, but it was buried in situ.

In Northern Europe, the tradition of making dugout canoes survived into the 20th and 21st centuries only in Estonia, where seasonal floods in Soomaa, a 390 km² wilderness area, make conventional means of transportation impossible. In recent decades a new surge of interest in making dugouts (Estonian haabjas) has revitalized the ancient tradition.

The Americas

Dugout canoes were constructed throughout the Americas, where suitable logs were available. The indigenous people of the Pacific Northwest are very skilled at crafting wood. Best known for totem poles up to 80 feet (24 m) tall, they also construct dugout canoes over 60 feet (18 m) long for everyday use and ceremonial purposes.

In 1978, Geordie Tocher and two companions sailed a 3.5-short-ton (3.2 t), 40-foot (12 m) dugout canoe (the Orenda II), made of Douglas fir, and based on Haida designs (but with sails), from Vancouver, British Columbia, Canada to Hawaiʻi to add credibility to stories that the Haida had travelled to Hawaiʻi in ancient times. Altogether they ventured some 4,500 miles (7,242 km) after two months at sea.

The dugout canoes were made mostly of huge cedar logs in the state of Washington for the ocean travellers, but natives that lived on the smaller rivers used smaller cedar logs.

Pacific Islands

See also Māori migration canoes, Waka

In the Pacific Islands, dugout canoes are very large, made from whole mature trees and fitted with outriggers for increased stability in the ocean, and were once used for long-distance travel. Such are the very large waka used by Māori who came to New Zealand probably from East Polynesia, about 1280. Such vessels carried 40 to 80 warriors in calm sheltered coastal waters or rivers. It is believed that trans-ocean voyages were made in Polynesian catamarans and one hull, carbon-dated to about 1400, was found in New Zealand in 2011. In New Zealand smaller waka were made from a single log, often Totara, because of its lightness, strength and resistance to rotting. Larger waka were made of about seven parts lashed together with flax rope. All waka are characterized by very low freeboard. In Hawaiʻi, waʻa (canoes) are traditionally manufactured from the trunk of the koa tree. They typically carry a crew of six: one steersman and five paddlers.

The Pacific Ocean has been the nursery for many different forms of dugout sailing craft. They differ in their sail plan (i.e., crab-claw or half-crab-claw, Latin, or triangular), hull formats (single, double, catamaran or proa), the absence or presence of a beam (a bridge for a double hull). Hull shapes and end forms vary greatly. Masts can "be right or made of double spars." Hulls can be constructed by assembling boards or digging out tree trunks. Intended use (fish, war, sea voyage) and geographical features (beach, lagoon, reefs) are reflected in design. Importantly, there is an important dividing line: some craft use a tacking rig; others "shunt" that is change tack "by reversing the sail from one end of the hull to the other." Tacking rigs are similar to those seen in most parts of the world, but shunting rigs change tack by reversing the sail from one end of the hull to the other and sailing in the opposite direction (the "Pushmi-pullyu" of the sailing world).

John F. Kennedy's PT-109

The Solomon Islanders have used and continue to use dugout canoes to travel between islands. In World War II these were used during the Japanese occupation - with their small visual and noise signatures these were among the smallest boats used by the Allied forces in World War II. After the sinking of PT-109, Biuki Gasa reached the shipwrecked John F. Kennedy by dugout.
