Ships of Zhezhi during the Ming period

UPDATED DECEMBER 31, 2025

While not as prominent as the formidable Fu Chuan (福船) and Guang Chuan (廣船), warships from Zhezhi (浙直)—that is, the regions of Zhejiang and Nanzhili (南直隸, present-day Jiangsu, Anhui, and Shanghai)—were nevertheless a critical backbone of Ming naval power. 

Being adapted to the complex mix of riverine environments of the Yangtze estuary and the shallow coastal and archipelagic waters of the southeastern seaboard, including the numerous islets of the Zhoushan archipelago, ships from Zhezhi exhibited a greater variety in designs, although they were generally characterised by their relatively small size (compared to the Fu Chuan and Guang Chuan), flat bottoms, and use of cloth sails.

Cang Shan Chuan (蒼山船, lit. 'Mount Cang's ship')

Cang Shan Chuan, also known as Cang Shan Tie (蒼山鐵, lit. 'Mount Cang's iron') and often shortened to Cang Chuan (蒼船), was the most representative ship of Zhezhi. It originated from Zhejiang Province, in particular Taiping County (太平縣, present-day Wenling City).

Being an extinct ship type, much less is known about the Cang Shan Chuan than about other Chinese ships like the Four Great Ancient Ships, although information gleaned from written materials reveals that Cang Shan Chuan had a V- or S-bottom hull that was narrower than the Fu Chuan but wider than the Sha Chuan (沙船), as well as wide prow and stern. It had two decks, the lowest level of the ship served as its ballast, while the main deck right above served as accommodation for the ship crew. All nautical operations of the Cang Shan Chuan, as well as primary fighting compartment of the militarised version of the ship, were located on its main deck, although a reinforced superstructure could still be installed for better protection. A true hybrid sail-and-yuloh ship, the Cang Shan Chuan typically featured cloth sails, and also came equipped with ten yuloh sculling oars, each sculled by four oarsmen. Unusually, all of its yulohs were mounted at the port and starboard quarters, rather than being evenly spread over the entire length of the ship.

Originally built as a fishing vessel, Cang Shan Chuan quickly gained favour in the Ming navy during the Wokou campaign due to its general robustness (which also gave rise to its "iron" moniker), all-weather mobility, and ability to traverse shallow waters unreachable by Fu Chuan. Unfortunately, being one of the smallest Ming warships, the Cang Shan Chuan was seen as merely on par, rather than superior to, Japanese warships, and therefore ill-suited for direct ramming attack and boarding action, as it could neither plough through Japanese ships like its larger cousins from Fujian and Guangdong, nor carry enough combatants to overwhelm the dangerous Japanese warriors in close combat. Nevertheless, Cang Shan Chuan excelled in the roles of patrolling, scouting, rescue operations, providing harassing firepower, pursuing fleeing ships, as well as picking dead bodies out of water after a naval engagement. 

Chong Mu Chuan (艟𦪞船)

Chong Mu Chuan was essentially an upsized Cang Shan Chuan that had its bamboo palisades removed (presumably to cut down on weight). Devised by famous Ming commander Qi Ji Guang (戚繼光) to better combat the Wokou, Chong Mu Chuan's greater size allowed it to overpower Japanese ships more easily without sacrificing the great mobility of the smaller Cang Shan Chuan.

Tie Tou Chuan (鐵頭船, lit. 'Iron-headed ship')

Tie Tou Chuan was a newer and slightly downsized version of the Chong Mu Chuan.

Similar to the Cang Shan Chuan it was based on, Tie Tou Chuan was described as being smaller and narrower than a Fu Chuan yet wider than a Sha Chuan, having a draught of four to five chi, a wide prow and stern, hybrid sail-and-yuloh propulsion with its six yulohs mounted at the port and starboard quarters, general robustness, all-weather mobility, and suitability for both shallow and deep waters.

Ba Jiang Chuan (八槳船, lit. 'Eight oar boat')

The second-most representative ship of Zhezhi, the Ba Jiang Chuan was a agile vessel fitted with sixteen oars, eight on each side, a stern-mounted yuloh, and (presumably) two masts. While poorly suited for direct combat, it excelled patrolling, scouting, and harassing enemy ships.

Shao Chuan (哨船, lit. 'Sentry ship')

Shao Chuan was an oceangoing sail-and-yuloh ship characterised by its V-bottom hull, high and pointed prow, wide stern, huge and tall sails, and large number of equipped yulohs. Originally used by fishermen from Ouhai (甌海) for deep-sea fishing, the ship's superb handling, speed, and agility also made it an excellent military vessel.

Ke Shao Chuan (殼哨船, lit. 'Shell sentry ship')

Ke Shao Chuan, also known as Ke Chuan (殼船, lit. 'Shell ship') and Ke Cao (殼艚, lit. 'Shell barge'), was, as its name suggests, an oceangoing fishing ship commonly used by clam-diggers from Wenzhou, characterised by its slender hull with minimal sheer and a V-bottom, as well as a wide stern.

Owing to the nature of clam-digging activities, these fishing vessels frequently fell prey to Wokou hijacking, the pirates preferring them over their own Japanese craft. Ming authorities eventually began to modify small Shao Chuan (see above) into decoy Ke Shao Chuan and mingle them with the ordinary fishing fleet to ambush the pirates.

Wang Suo Chuan (網梭船, lit. 'Net shuttle boat')

Wang Suo Chuan was a small fishing boat commonly used by fishermen from Dinghai (定海), Linhai Garrison (臨海衛), Guanhai Garrison (觀海衛), and Xiangshan County (象山縣) to fish at Xiabashan (下八山, part of the Zhoushan archipelago). It was the smallest of Zhezhi's fishing vessels, characterised by a hull that resembled a weaving shuttle, a bamboo mast, and a cloth sail. Despite its extremely small size (only fit for two or three crew members) and shallow 7–8 cun draught, the Wang Suo Chuan was surprisingly seaworthy, able to traverse open ocean just as well as the narrowest brooks and channels—not to mention that this shallow draught, combined with the vessel’s lightweight construction, allowed the boat to be readily dragged ashore by its small crew, offering a reliable way to evade severe weather.

While poorly suited for direct combat, the Wang Suo Chuan excelled in patrolling, scouting, and harassing enemy ships. Furthermore, thanks to its low cost, hundreds of Wang Suo Chuan—each carrying one or two matchlockmen—could be amassed easily to swarm a single ship.

Niao Zui Chuan (鳥嘴船, lit. 'Bird's beak ship')

Niao Zui Chuan was a small fishing ship originating from Wenzhou (溫州), Taizhou (台州), Songmen (松門), and Haimen (海門) of Zhejiang Province. The ship was characterised by a distinctive prow that resembled a bird's beak. Normally propelled by sail, it could also be sculled by its single stern-mounted yuloh when there was no wind.

Shui Ju Chuan (水艍船)

Shui Ju Chuan was a new type of Zhejiang warship that came into prominence in the final years of the Ming Dynasty and remained in use well into Qing period. It appeared to be a downsized version of the Gan Zeng Chuan (趕繒船), possibly as a result of transmission Fu Chuan technology into Zhejiang, or a fusion of the two shipbuilding traditions. Shui Ju Chuan was primarily equipped with breech-loading swivel guns and heavy matchlocks instead of heavier ordnance like its larger cousin.
