During the Song and Yuan dynasties, Chinese ocean-going wooden sailing ships were favored by merchants and envoys from various countries. The main reason was that Chinese sailing ships were very safe, which came from the watertight bulkheads in the sailing ships. The so-called watertight bulkheads are independent and watertight compartments separated by transverse bulkheads in the cabin. The use of watertight bulkheads not only increases the strength of the hull, but also does not endanger other compartments even if a compartment hits a reef and takes in water, thus ensuring the safety of the ship's navigation. At the same time, the watertight bulkheads, as the support points for the bending of the hull plate, also improve the solidity of the sailing ship. my country's watertight bulkhead shipbuilding technology was introduced to the West by Marco Polo as early as the end of the 13th century. Since then, this technology has gradually been widely adopted by the shipbuilding industry of various countries in the world, and has had an important impact on the development of human navigation. In ancient times, Quanzhou was known for its developed shipbuilding industry. According to the "Xishan Magazine" during the Jiaqing period of the Qing Dynasty, during the Tianbao period of the Tang Dynasty, the seagoing ships built in Quanzhou had "fifteen compartments", that is, 15 compartments on the ship. Unearthed cultural relics prove that at least in the Song Dynasty, the seagoing ships built in Quanzhou had adopted a mature watertight bulkhead structure. The traditional watertight bulkhead wooden sailing ship construction technology still exists in Shenhu Town, Jinjiang City, Quanzhou, and the local people are designing wooden sailing ships according to the traditional model. The sailing ships built follow the tradition from ship design, material selection, construction technology, exterior painting to various rituals in the construction process. 14 bulkheads divide the ship into 15 cabins. There are two water holes under the bulkheads near the keel. The gaps between each bulkhead are sealed with tung oil putty and hemp rope to ensure that the cabins are isolated from each other. The shipbuilding skills of Qihou Village, Zhangwan Town, Jiaocheng District, Ningde City were introduced from southern Fujian during the Hongwu period of the Ming Dynasty, and have been passed down from generation to generation until today. During the Republic of China period, Zhangwan manufactured "three-masted" wooden sailing ships with a tonnage of 200-300 tons. After the founding of New China, Zhangwan Shipyard undertook the construction of a large number of fishing boats and transport ships, many of which were watertight bulkhead wooden sailing ships with a tonnage of more than 60 tons. After the reform and opening up in the 1980s, the manufacturing industry of Fuzhou boats in Zhangwan has been shrinking due to the widespread use of metal boats. Although Qihou Village still retains small-scale production, the number of inheritors is decreasing, and the watertight compartment Fuzhou boat manufacturing skills are in danger. With the development of modern transportation, wooden boats are increasingly losing their living soil, the wooden boat production industry is also declining, and the manufacturing skills are gradually lost. Under this situation, corresponding rescue and protection measures must be formulated as soon as possible to ensure the effective inheritance of traditional wooden boat manufacturing, a precious folk handicraft.
