A few days after South China Sea I began to be excavated in early June 2007, a second wreck, named South China Sea-II was discovered using satellite navigation. The official Xinhuanews agency cited Guangdongarchaeologists and said the wreck was 7 to 18 m long and at a depth of 20 m, and also cited preliminary studies showing the ship shows it may have sunk after hitting a reef around the early 17th century.
