Construction[ edit ] Building a seagoing dugout. The sides have likely been heated and bent outward. 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.

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. Africa[ edit ] The Dufuna canoe from Nigeria is an 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. Asia[ edit ] Remains of an year-old dugout excavated in China An year-old dugout canoe was found by archaeologists in Kuahuqiao , Zhejiang Province , in east China. First, was abundant in the Paleolithic after the melting of the Weichselian glaciation and readily available.

Secondly it grew to be one of the tallest trees in the forests of the time, making it easier to build longer boats. It is lighter and therefore boats made from it have a better cargo capacity and are easier to carry, than most other tree types from the European old-growth forests.

Other dugouts discovered in the Netherlands include two in the province of North Holland: In German , the craft are known as einbaum one-tree. In the old Hanseatic town of Stralsund three log-boats were excavated in Two of the boats were around 7, years old and are the oldest boats found in the Baltic area. The third boat 6, years old was 12 meters long and holds the record as the longest dugout in the region.

The finds have partly deteriorated due to poor storage conditions. The boat has since been dated to be 6, years old. The boat has holes suggesting that it had an outrigger or was joined to another boat.

They used dugouts to attack Constantinople and to withdraw into their lands with bewildering speed and mobility. 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. More than 40 pre-historic log-boats have been found in the Czech Republic.

It was cut out of a single oak log and has a width of 1. Geographically, Czech log-boat sites and remains are clustered along the Elbe and Morava Rivers.

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 712 m in length, and the largest of them could carry up to 1.

The Lewin type logboats are usually associated with the Przeworsk culture in the early centuries AD. 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. They have been carbon dated to the years BCE and they are the oldest known boats in Northern Europe. Eventually, the dugout portion was reduced to a solid keel , and the lashed boards on the sides became a Lapstrake hull.

The Iron Age residents of Great Britain , were known to have used logboats for fishing and basic trade. In , a logboat was uncovered in Poole Harbour , Dorset. The Poole Logboat dated to 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 in Shardlow south of Derby. It has been dated to the Bronze Ages around 1. There was another pre-historic boat at the same location, but it was buried in situ. In recent decades a new surge of interest in making dugouts Estonian haabjas has revitalized the ancient tradition. Pacific Northwest canoes Native Americans making a dugout canoe, 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. 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 , was found in New Zealand in Larger waka were made of about seven parts lashed together with flax rope. All waka are characterized by very low freeboard. They typically carry a crew of six: The Pacific Ocean has been the nursery for many different forms of dugout sailing craft.

They differ in their sail plan i. Hull shapes and end forms vary greatly. Masts can "be right or made of double spars. Intended use fish, war, sea voyage and geographical features beach, lagoon, reefs are reflected in design.

Importantly, there is an important dividing line: 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.

Tanner Broadwell, 26, and Nikki Walsh, 24, sold everything they owned in Colorado to buy a sailboat and live their best lives on the open sea. But that ship set sail for them when their boat sank.

Starting at the Thames Flood Barrier at Woolwich in South East London it runs along the banks of the Thames to .
