Zheng He’s Enormous Treasure Ships | Amazing Images.
Between 1405 and 1433, during the Ming era, Chinese Admiral Zheng He,
who was also the court eunuch, commanded seven expeditionary voyages as
far away as East Africa and Middle East. These expeditions, known in
Chinese history as the treasure voyages, consisted of hundreds of ships
of enormous dimensions carrying a crew as large as 28,000 and great
amounts of treasures. The purpose of the voyages were to project Chinese
power and wealth to the outside world, as well as to establish imperial
control over the maritime trade.
Zheng He dedicated the last 28 years of his life to marine navigation until he died during or shortly after his seventh and final voyage. When Zheng He returned, China had a new emperor who was uninterested in the continuation of such government-sponsored naval adventures. The Treasure Shipyard in Nanjing, where Zheng He’s massive fleet was built was shut down, abandoned and subsequently lost to history.

If recorded accounts are taken as factual, Zheng He's treasure ships were mammoth in size with nine masts and four decks, capable of accommodating more than 500 passengers, as well as a massive amount of cargo. Some of the ships were said to have been 137 meters (450 feet) long and 55 meters (180 feet) wide, which was at least twice as long as the largest European ships of that time. Some sources claim the ships were even longer — 180 meters (600 feet).
Modern scholars argue that Zheng He's ships couldn’t have been that long because wooden ships of such extreme sizes would have pushed the limits of what was possible in wooden ship construction making them unwieldy. There are evidences in later historical periods when ships longer than 100 meters were built, such as HMS Orlando and the schooner Wyoming, and they suffered structural problems. In heavy seas, the ships flexed causing the long planks to twist and buckle. The first ships to attain 126 meters length were 19th century steamers with iron hulls.

However, scholars agree that the treasure ships were considerably large, some estimating the largest ones to be between 119–124 meters (390–408 feet) in length, while more conservative estimates puts them at about 60–76 meters (200–250 feet).
Compared with other ships, treasure ships were wide in ratio to their length which helped them achieve stability. The hull was V-shaped, the keel long and the ballast heavy. Treasure ships also used floating anchors cast off the sides of the ship in order to increase stability. Watertight compartments were also used to add strength to the treasure ships. The ships also had a balanced rudder which could be raised and lowered, creating additional stability like an extra keel.
In 2005, a Treasure Shipyard park was created in the heart of Nanjing, where several scaled-down replicas of treasures ships are to be found including a full-sized model of one of Zheng He’s smaller vessels.
