The Princess Taiping (Chinese: 太平公主; pinyin: Tàipíng Gōngzhǔ) was a replica of a Ming Dynasty Chinese junk built for a sailing trip from China to the United States and back.[1] The ship sank approximately 42 nautical miles (78 km) from its final destination on Saturday, 25 April 2009.[2] If successful, it would have been the first ship of its kind known to have done so.[2] (Fifty years earlier, a junk called Free China had been sailed to San Francisco but none had ever made the more difficult return journey to China.[3])
