DEVELOPED in south China's Fujian Province, the watertight-bulkhead technology of Chinese junks permits the construction of ocean-going vessels with watertight compartments. If one or two cabins are damaged, seawater will not flood other cabins and the vessel will remain afloat.
The junks are made mainly of camphor, pine and fir timber, and assembled through use of traditional carpenters' tools. They are built by applying the key technologies of rabbet-jointing planks together and caulking the seams between the planks with ramie, lime and tung oil.
The construction is directed by a master craftsman who oversees a large number of craftsmen, working in close coordination. Local communities participate by holding solemn ceremonies to pray for peace and safety during construction and before the launch.
The experience and working methods of watertight-bulkhead technology are transmitted orally from master to apprentices. However, the need for Chinese junks has decreased sharply as wooden vessels are replaced by steel-hulled ships, and today only three masters can claim full command of the craft. Costs have also increased owing to a shortage in raw materials.
The watertight-bulkhead technology of Chinese junks was inscribed on the List of Intangible Cultural Heritage in Need of Urgent Safeguarding by UNESCO in 2010.
