The manufacturing history of Tianyuan treasure ship

Zheng He's voyage to the West promoted the development of shipbuilding technology. In order to resist the damage of waves, it is required to improve the quality of treasure ships. During the Yongle period, Longjiang Shipyard specially dispatched a large number of craftsmen from Zhejiang, Jiangxi, Huguang, Fujian and other places, becoming a place where skilled craftsmen gathered. Then a huge treasure ship 44 feet long and 18 feet wide appeared. Zheng He's fleet has many ships and various models, which is due to the different shipbuilding technologies in different places.

As for the Dabao ship type used by Zheng He's voyage to the West, Xi Longfei said in the History of Shipbuilding in China that Fujian has always been a shipbuilding center; There's another sentence in the Record of Ming Taizu's Cheng Zu: "I will send envoys to the Western Ocean and order Fujian to build five seagoing ships". More because the width ratio of captain Dabao is small; And traveled across the ocean to Africa, so he thought it was not sharp and deep.

The "lucky boat" with a small aspect ratio of water belongs to it. However, due to the installation of anti-drift and other accessories on the large sand boat, it is also possible to use the sand boat in Zheng He's fleet.
