Caulk
Caulk or, less frequently, caulking is a material used to seal joints or seams against leakage in various structures and piping. The oldest form of caulk consisted of fibrous materials driven into the wedge-shaped seams between boards on wooden boats or ships. Cast iron sewerage pipe were formerly caulked in a similar way. Riveted seams in ships and boilers were formerly sealed by hammering the metal. Modern caulking compounds are flexible sealing compounds used to close up gaps in buildings and other structures against water, air, dust, insects, or as a component in firestopping.
Foreign relations of imperial China
For the later history after 1800 see History of foreign relations of China. The foreign relations of Imperial China from the Qin dynasty until the Qing dynasty encompassed many situations as the fortunes of dynasties rose and fell. Chinese culture had influenced neighboring and distant countries, while being transformed by outside influences as well as being conquered. During the Western Han dynasty, the Silk Road trade routes were established and brought Hellenistic Central Asia, Persia under the Parthian Empire, and South Asia into contact with the Chinese empire.
Chinese treasure ship
A Chinese treasure ship (, literally "gem ship") is a type of large wooden ship in the fleet of admiral Zheng He, who led seven voyages during the early 15th-century Ming dynasty. The size of the Chinese treasure ship has been a subject of debate with the Chinese records mentioning the size of 44 zhang or 44.4 zhang, which has been interpreted by some as over in length, while others have stated that Zheng He's largest ship was about or less in length. According to the zh (1658), the first voyage consisted of 63 treasure ships crewed by 27,870 men.
Dhow
Dhow (daʊ; داو; dāw) is the generic name of a number of traditional sailing vessels with one or more masts with settee or sometimes lateen sails, used in the Red Sea and Indian Ocean region. Typically sporting long thin hulls, dhows are trading vessels primarily used to carry heavy items, such as fruit, fresh water, or other heavy merchandise, along the coasts of Eastern Arabia, East Africa, Yemen and coastal South Asia (Pakistan, India, Bangladesh). Larger dhows have crews of approximately thirty, smaller ones typically around twelve.
Galleon
Galleons were large, multi-decked sailing ships developed in Spain and first used as armed cargo carriers by Europeans from the 16th to 18th centuries during the age of sail and were the principal vessels drafted for use as warships until the Anglo-Dutch Wars of the mid-1600s. Galleons generally carried three or more masts with a lateen fore-and-aft rig on the rear masts, were carvel built with a prominent squared off raised stern, and used square-rigged sail plans on their fore-mast and main-masts.
Great Divergence
The Great Divergence or European miracle is the socioeconomic shift in which the Western world (i.e. Western Europe and the parts of the New World where its people became the dominant populations) overcame pre-modern growth constraints and emerged during the 19th century as the most powerful and wealthy world civilizations, eclipsing previously dominant or comparable civilizations from the Middle East and Asia such as the Ottoman Empire, Mughal India, Safavid Iran, Qing China and Tokugawa Japan, among others.
Proa
Proas are various types of multi-hull outrigger sailboats of the Austronesian peoples. The terms were used for native Austronesian ships in European records during the Colonial era indiscriminately, and thus can confusingly refer to the double-ended single-outrigger boats of Oceania, the double-outrigger boats of Island Southeast Asia, and sometimes ships with no outriggers or sails at all. In its most common usage, the term proa refers to the Pacific proas which consist of two (usually) unequal-length parallel hulls.
Lashed-lug boat
Lashed-lug boats are ancient boat-building techniques of the Austronesian peoples. It is characterized by the use of sewn holes and later dowels ("treenails") to stitch planks edge-to-edge onto a dugout keel and solid carved wood pieces that form the caps for the prow and stern. The planks are further lashed together and to ribs with fiber ropes wrapped around protruding carved lugs on the inside surfaces. Unlike carvel construction, the shell of the boat is created first, prior to being fastened to the ribs.
Deck (ship)
A deck is a permanent covering over a compartment or a hull of a ship. On a boat or ship, the primary or upper deck is the horizontal structure that forms the "roof" of the hull, strengthening it and serving as the primary working surface. Vessels often have more than one level both within the hull and in the superstructure above the primary deck, similar to the floors of a multi-storey building, that are also referred to as decks, as are certain compartments and decks built over specific areas of the superstructure.
