Chinese treasure ship

A Chinese treasure ship (Chinese: 宝船; pinyin: bǎochuán) was a type of large wooden ship in the fleet of admiral Zheng He, who led seven voyages during the early 15th-century Ming Dynasty. Scholars disagree about the factual accuracy and correct interpretation of accounts of the treasure ships.The purported dimensions of these ships at 137 m (450 ft) long and 55 m (180 ft wide) are at least twice as long as the largest European ships at the end of the sixteenth century. The tonnage Needham mentions is wrong by an order of magnitude as a result of a calculational error and, rather than 2,800-3,500 tons, should be stated as 28,000-35,000 tons. In terms of wooden ships of all time the stated length is greater than the Greek Tessarakonteres of 2nd century AD which were reported to be as long as 128 m (425 ft). Treasure ships' dimensions are debated on practical engineering grounds, with some suggesting they were as short as 61–76 m (200–250 feet) or that they could only have been used on special occasions in the relative safety of the lower Yangtze River. Although a claimed treasure ship rudder has been unearthed in Nanjing, China, its size is no larger than rudders known to have been used in <60m long Jiangsu traders in the 1930s, so cannot be taken as evidence of the uprooted giant dimensions.
