Discovery

The Quanzhou ship was discovered in 1973 and excavated by Chinese archaeologists during the summer of 1974, from 2–3 meters of mud in the shore area of Quanzhou Bay. The excavation was led by the local archaeologist, professor of history at Xiamen University

It is thought that in the 13th century a shipping channel ran in that area. During the heyday of Quanzhou as one of China's major sea ports, the area corresponded to the ancient Houzhou Harbor (后渚港, Houzhougang; Hou-to in Wake (1997).

The parts of the ship located above the original waterline had perished, but the lower parts of the hull had been preserved fairly well in mud and water.

The main evidence for dating the vessel comes from 504 copper coins found inside the hull. Seventy of them date to the Song Dynasty, with the "youngest" of them dating to 1272. Based on this, the archaeologists concluded that the ship must have sunk within a few years after 1272 - that is, during the very last years of the Southern Song Dynasty (which fell to the Mongols in 1279), or perhaps already after the Mongol conquest of South China.

The ship is presently preserved in Quanzhou Overseas Relations Museum (泉州海外交通史博物馆), which has a special "Quanzhou Bay Ancient Ships Exhibit" dedicated to this vessel and several other vessels recovered in similar circumstances. The exhibit is located in the former Kaiyuan Temple. The exhibit also includes a modern model of the ship as it must have looked like during its working life.
