Building a wooden boat is a huge undertaking, especially something as large as a cabin cruiser or day sailer. Take a class at Mystic Seaport and learn from the ground up.
Lofting a boat alone can be a real brain tester. Start with a rowboat or canoe, and see how it goes. From Taiwan , they first settled the island of Luzon in the Philippines before migrating onwards to the rest of Island Southeast Asia and to Micronesia by BC, covering distances of thousands of kilometers of open ocean.
This was followed by later migrations even further onward; reaching Madagascar in the Indian Ocean and New Zealand and Easter Island in the Pacific Ocean at its furthest extent, possibly even reaching the Americas. Austronesians invented unique ship technologies like catamarans , outrigger boats , lashed-lug boatbuilding techniques, crab claw Wooden Model Ship Building Supplies Name sails , and tanja sails ; as well as oceanic navigation techniques.
They also invented sewn-plank techniques independently. Austronesian ships varied from simple canoes to large multihull ships. The simplest form of all ancestral Austronesian boats had five parts. The bottom part consists of a single piece of hollowed-out log. At the sides were two planks, and two horseshoe-shaped wood pieces formed the prow and stern. These were fitted tightly together edge-to-edge with dowels inserted into holes in between, and then lashed to each other with ropes made from rattan or fiber wrapped around protruding lugs on the planks.
This characteristic and ancient Austronesian boat-building practice is known as the " lashed-lug " technique. They were commonly caulked with pastes made from various plants as well as tapa bark and fibres which would expand when wet, further tightening joints and making the hull watertight. They formed the shell of the boat, which was then reinforced by horizontal ribs. Shipwrecks of Austronesian ships can be identified from this construction, as well as the absence of metal nails.
Austronesian ships traditionally had no central rudders but were instead steered using an oar on one side. The ancestral Austronesian rig was the mastless triangular crab claw sail which had two booms that could be tilted to the wind.
These were built in the double-canoe configuration or had a single outrigger on the windward side. In Island Southeast Asia, these developed into double outriggers on each side that provided greater stability.
The triangular crab claw sails also later developed into square or rectangular tanja sails , which like crab claw sails, had distinctive booms spanning the upper and lower edges. Fixed masts also developed later in both Southeast Asia usually as bipod or Wooden Model Ship Building Videos Names tripod masts and Oceania. These sails allowed Austronesians to embark on long-distance voyaging. The ancient Champa of Vietnam also uniquely developed basket-hulled boats whose hulls were composed of woven and resin - caulked bamboo, either entirely or in conjunction with plank strakes.
The acquisition of the catamaran and outrigger technology by the non-Austronesian peoples in Sri Lanka and southern India is due to the result of very early Austronesian contact with the region, including the Maldives and the Laccadive Islands via the Austronesian maritime trade network the precursor to both the Spice Trade and the Maritime Silk Road , estimated to have occurred around to BCE and onwards.
This may have possibly included limited colonization that have since been assimilated. This is still evident in Sri Lankan and South Indian languages.
Early contact with Arab ships in the Indian Ocean during Austronesian voyages is also believed to have resulted in the development of the triangular Arabic lateen sail. Early Egyptians also knew how to assemble planks of wood with treenails to fasten them together, using pitch for caulking the seams. The " Khufu ship ", a Early Egyptians also knew how to fasten the planks of this ship together with mortise and tenon joints. The oldest known tidal dock in the world was built around BC during the Harappan civilisation at Lothal near the present day Mangrol harbour on the Gujarat coast in India.
Other ports were probably at Balakot and Dwarka. However, it is probable that many small-scale ports, and not massive ports, were used for the Harappan maritime trade. The ships of Ancient Egypt's Eighteenth Dynasty were typically about 25 meters 80 ft in length, and had a single mast , sometimes consisting of two poles lashed together at the top making an "A" shape. They mounted a single square sail on a yard , with an additional spar along the bottom of the sail.
These ships could also be oar propelled. The ships of Phoenicia seem to have been of a similar design. The Chinese built large rectangular barges known as "castle ships", which were essentially floating fortresses complete with multiple decks with guarded ramparts. However, the Chinese vessels during this era were essentially fluvial riverine. True ocean-going fleets did not appear until the 10th century Song dynasty. There is considerable knowledge regarding shipbuilding and seafaring in the ancient Mediterranean.
The ancient Chinese also built ramming vessels as in the Greco-Roman tradition of the trireme , although oar-steered ships in China lost favor very early on since it was in the 1st century China that the stern -mounted rudder was first developed. This was dually met with the introduction of the Han Dynasty junk ship design in the same century.
It is thought that the Chinese had adopted the Malay junk sail by this period, [29] although a UNESCO study argues that the Chinese were using square sails during the Han dynasty and adopted the Malay junk sail later, in the 12th century.
The Malay and Javanese people , started building large seafaring ships about 1st century AD. Large ships are about 50�60 metres � ft long, had 5. This type of ship was favored by Chinese travelers, because they did not build seaworthy ships until around 8�9th century AD. Southern Chinese junks were based on keeled and multi-planked Austronesian jong known as po by the Chinese, from Javanese or Malay perahu - large ship.
This is different from northern Chinese junks, which are developed from flat bottomed riverine boats. Archeological investigations done at Portus near Rome have revealed inscriptions indicating the existence of a 'guild of shipbuilders' during the time of Hadrian. Until recently, Viking longships were seen as marking a very considerable advance on traditional clinker -built hulls of plank boards tied together with leather thongs. Haywood [39] has argued that earlier Frankish and Anglo-Saxon nautical practice was much more accomplished than had been thought, and has described the distribution of clinker vs.
The ship was 26 metres 85 ft long and, 4. Upward from the keel, the hull was made by overlapping nine strakes on either side with rivets fastening the oaken planks together. It could hold upwards of thirty men.
Sometime around the 12th century, northern European ships began to be built with a straight sternpost , enabling Wooden Ship Building School China the mounting of a rudder, which was much more durable than a steering oar held over the side. Development in the Middle Ages favored "round ships", [41] with a broad beam and heavily curved at both ends. Another important ship type was the galley which was constructed with both sails and oars. The first extant treatise on shipbuilding was written c.
He wrote and illustrated a book that contains a treatise on ship building, a treatise on mathematics, much material on astrology, and other materials. His treatise on shipbuilding treats three kinds of galleys and two kinds of round ships. Outside Medieval Europe, great advances were being made in shipbuilding. The mainstay of China's merchant and naval fleets was the junk , which had existed for centuries, but it was at this time that the large ships based on this design were built.
During the Sung period � AD , the establishment of China's first official standing navy in AD and the enormous increase in maritime trade abroad from Heian Japan to Fatimid Egypt allowed the shipbuilding industry in provinces like Fujian to thrive as never before.
The largest seaports in the world were in China and included Guangzhou , Quanzhou , and Xiamen. In the Islamic world, shipbuilding thrived at Basra and Alexandria , the dhow , felucca , baghlah and the sambuk , became symbols of successful maritime trade around the Indian Ocean ; from the ports of East Africa to Southeast Asia and the ports of Sindh and Hind India during the Abbasid period. At this time islands spread over vast distances across the Pacific Ocean were being colonised by the Melanesians and Polynesians, who built giant canoes and progressed to great catamarans.
Shipbuilders in the Ming dynasty primarily worked for the government, under command of the Ministry of Public Works. During the early years of the Ming dynasty, the Ming government maintained an open policy towards sailing.
Between and , the government conducted seven diplomatic Ming treasure voyages to over thirty countries in Southeast Asia, India, the Middle East and Eastern Africa. Six voyages were conducted under the Yongle Emperor's reign, the last of which returned to China in After the Yongle Emperor's death in , his successor the Hongxi Emperor ordered the suspension of the voyages.
The seventh and final voyage began in , sent by the Xuande Emperor. Although the Hongxi and Xuande Emperors did not emphasize sailing as much as the Yongle Emperor, they were not against it.
This led to a high degree of commercialization and an increase in trade. Large numbers of ships were built to meet the demand. The Ming voyages were large in size, numbering as many as ships and 28, men. Shachuan , or 'sand-ships', are ships used primarily for inland transport. It is said in vol. The shipyard was under the command of Ministry of Public Works. The shipbuilders had no control over their lives. The builders, commoner's doctors, cooks and errands had lowest social status.
There were two major ways to enter the shipbuilder occupation: family tradition, or apprenticeship. If a shipbuilder entered the occupation due to family tradition, the shipbuilder learned the techniques of shipbuilding from his family and is very likely to earn a higher status in the shipyard. Additionally, the shipbuilder had access to business networking that could help to find clients. If a shipbuilder entered the occupation through an apprenticeship, the shipbuilder was likely a farmer before he was hired as a shipbuilder, or he was previously an experienced shipbuilder.
Many shipbuilders working in the shipyard were forced into the occupation. The ships built for Zheng He's voyages needed to be waterproof, solid, safe, and have ample room to carry large amounts of trading goods. Therefore, due to the highly commercialized society that was being encouraged by the expeditions, trades, and government policies, the shipbuilders needed to acquire the skills to build ships that fulfil these requirements.
Shipbuilding was not the sole industry utilising Chinese lumber at that time; the new capital was being built in Beijing from approximately onwards, [44] which required huge amounts of high-quality wood.
These two ambitious projects commissioned by Emperor Yongle would have had enormous environmental and economic effects, even if the ships were half the dimensions given in the History of Ming.
Considerable pressure would also have been placed on the infrastructure required to transport the trees from their point of origin to the shipyards.
Shipbuilders were usually divided into different groups and had separate jobs. Some were responsible for fixing old ships; some were responsible for making the keel and some were responsible for building the helm. Joinery is the interior woodwork. They built and finished the deck houses, the galley Galley joinery The kitchen on board a vessel. Read more was often very elaborate and required highly-skilled joinery work.
Painters applied coatings to protect the wood. After the ship was launched, the crew became painters, for painting never ended. Sometimes a vessel had a figurehead Figurehead A carved wooden statue or figure attached to the bow under the bowsprit of a vessel. The figurehead was mounted on the bow Bow Forward part or head of a vessel.
While the hull was being built, spar Spar A round timber or metal pole used for masts, yards, booms, etc. After the Civil War, most spar timber came from the West Coast, which had a large supply of Sitka spruce and Douglas fir.
After squaring and tapering the timber, spar makers shaped the spar into an eight-sided timber and finished it round. Shipbuilders used shear legs Shear legs shears A temporary structure of two or three spars raised at an angle and lashed together at the point of intersection.
Riggers Rigging The term for all ropes, wires, or chains used in ships and smaller vessels to support the masts and yards standing rigging and for hoisting, lowering, or trimming sails to the wind running rigging. Running rigging lines move through blocks and are not wormed, parceled, or served. They are wormed, parceled, and served for water-proofing. To protect it from rot, rigging was given a waterproof cover, a process called worming Worming Running a small line up a rope, following the lay of the line.
Running rigging Running rigging The part of the rigging that includes the ropes that move the rig: move yards and sails, haul them up and lower them, move masts, and hoist weights.
There are many kinds of blocks. Blocks with ropes run through them form a tackle. Then the rigger set up all of the spars, preparing them to receive sails, attaching iron work and blocks, and running all of the rest of the lines. A ship was constructed on large wooden blocks and posts called shores Shore A prop or beam used for support during vessel construction. Before launching, ship carpenters built a cradle Cradle In shipbuilding and maintenance, the structure that supports a vessel upright on land and in which a vessel can be moved.
Dozens of wedges made up the cradle and were driven just before launching to transfer the weight of the ship from the blocks to the cradle. A festive launching could attract hundreds of friends, neighbors, and curious spectators.
Henry B. Jump to Navigation. Keel and Frames The keel Keel The chief timber or piece extending along the length of the bottom of a vessel from which rise the frames, stem, and sternposts.
