The pinned topic left out Zheng He's fleet during the Ming Dynasty...he had 9 masted "treasure ships" that were over 440 feet long { see below for an upper limit >10% smaller, and with the drawbacks of this still outlined} and displaced 1500 tons...which is about 11 times bigger than biggest European ships a century later. Complete with rows of bronze cannons.
*and recently on the history {channel}, they had a program on this.
Don't believe everything you hear.
To expand on Tadamsons reply to the above;
Although I do doubt the sailing chatacteristics of the huge treasure ships, as do experienced naval commentators, I think the Chinese need credit for advanced boat designs even in the Han period (early keels) Song waterwheels and watertight seperate compartments by the Ming period, although it should be noted boats in the Treasure fleet were still lost during the journey.
That being said this enthusiasm for the Treasure Fleets boat building technology does need to be tempered with the fact this modern new interest in Zheng He has to do with the plainly silly and fictious works of the incompetent and eccentric historian Gavin Menzies.
The pictures of a Zheng He ship looming over a European ship like a star destroyer at the beginning of Star Wars 1978 are just to me the nauctical & psychological equvialent of the big car as a penis extension. It is just ostentatious.
The actual 'treasure' ships were a small part of the combined fleet, built to statisfy a monumental ego, and probably sailed with the dynamics of a brick.
Combat by the treasure fleet fell on smaller and swifter boats for obvious reasons.
Most assuredly the massive boats were about awe, which goes a way to explaining why if there was any benefit to these that such ships were never built like this for seafaring anywhere again.
The limiting of # masts after Zheng He does not explain why nobody before or over the next 400 years ever revived such a design, i.e in crucial periods such as facing the navys of Europeans for example.
The huge boats were an addition for reasons of grandeur, and in the truest sense of the word.....a show boat.

QUENTIN MCDERMOTT: In Hong Kong, at the city's maritime museum, there's an equally sceptical critic.
And your argument of course is that if the junks had been as big as Gavin Menzies claims, then there would have been illustrations to show that.
STEPHEN DAVIES, DIRECTOR, HONG KONG MARITIME MUSEUM: There's no question. I mean, I'm sure if we've got a contemporary illustration, had there been an absolute behemoth, somebody would have drawn a picture. There's a lot of graphic art in China of that era, and I can't imagine that it would have been completely ignored.
QUENTIN MCDERMOTT: Stephen Davies, the maritime museum's director, doesn't buy Gavin Menzies' theory that fleets of gigantic junks circumnavigated the world in two years.
STEPHEN DAVIES, DIRECTOR, HONG KONG MARITIME MUSEUM: If the ships were as big as he says it was, they would be barely mobile. The drag, everything, would have meant that they would barely have moved at all, unless it was blowing a gale. Now, Zheng He, his fleet is supposed to have headed off around the world, mapping as they went, scientifically observing everything that they saw, and to have averaged something like four to five knots. Forget it. It didn't happen.
GAVIN MENZIES, AUTHOR: I said in my book, in my view, the junks were over 400ft long and 200ft wide, and a lot of very-well respected marine engineers say this is nonsense. A ship that size would hog and sag and break up in heavy sea, impossible to build - and I'm not saying that - that - that - the people who say they couldn't be built that size might eventually be proved right.
I found one picture of Zheng He's fleet said to be from the 17th century.
The # masts is rather more ordinary which is why the character of the fleet should not focus on just the remarkable & largest treasure ships. Of main masts it appears the number in this vision of several boats of the fleet is 4. Even if the huge ships (of uncertain size) existed it seems the character of the greater # vessels of the main body were perhaps not quite as grand....and a little more practical than the treasure ships.
There is evidence that really huge boats were built (including some recovered timbers that support huge dimensions), but just because they were built...does that make the treasure ships a really good idea?
Edit;
The 17th century image of Zheng He's fleet is on Wikipedia;Zheng He.
When China Ruled the Seas
The Treasure Fleet of the Dragon Throne 1405 - 1433
Louise LevathesIt is the source of the figures for different ships in the fleet on Wiki.
It does give some doubt to the practicality of the largest ships, but suggest ego may have won over in the end. The precise figures are even doubted by this author too, and
using even Ming dynasty figures there is a potential to inflate or deflate the figures by around 25% (*see below)

The shipwrights at Longjiang created a new vessel for the treasure fleet, combining these two boat designs. In keeping with the enormity of the emperor¹s desire to show the world the greatness of his reign and the righteousness of his claim to the throne, the grandest of the treasure ships in the fleet was enormous. Some historical records give its dimensions in complicated accounting characters rather than simplified ones, leaving no doubt as to the exact figures. The bao chuan (treasure boat) or long chuan (dragon boat) were "44 zhang 4 chi long and 18 Zhang wide." However, the official length of a chi, or Chinese foot, varied considerably throughout the Ming Dynasty, from 9.5 inches to over 13 inches. Moreover, the chi varied depending on what it was being used to construct and where it was being used; building standards in the empire were not uniform.
Early calculations of the size of the treasure ships were based on a chi of 12.129 inches (Ming gong bu chi) or 13.338 inches (Huai chi), which were the standards in Jiangsu province for the building of shachuan. Based on these chi, a ship of 44 zhang (1 Zhang equals 10 chi) would be 448.8 to. 49 3.5 feet long. A wooden sailing ship of this length would be very difficult to maneuver, if indeed it were seaworthy, which seems doubtful. Most scholars now believe that the treasure ships, though built in Nanjing, were fuchuan in their basic design, and that the Longjiang shipwrights, the majority of whom were from the coastal provinces, would have brought their tools with them. Based on actual shipbuilding chi unearthed in Fujian province, which varied in length from 10-53 to 11.037 inches, the largest of the treasure ships is now thought to have been between about 390 and 40 8 feet long and 160 to 166 feet wide‹still one of the largest wooden sailboats ever built anywhere in the world.
The number "444" (44 zhang, 4 chi, or 444 chi) prescribed for the length of this important imperial ship was certainly no accident. Four was the symbol for the earth, which was thought to be "four cornered." The Middle Kingdom was imagined to be in the middle of four seas. There are four cardinal directions, four seasons, and, according to Confucian philosophy, si wei, "four bonds" or virtues: propriety, integrity, righteousness, and modesty. All were auspicious associations for the treasure ships.
The treasure ships were longer than any oceangoing boat previously built in China but not inconsistent with the style and stature of early ship models. In the Tang dynasty ships were 20 zhang long, and in the Song they approached 40 zhang. The ke zhou (guest ships) of the Song emperor Huizong were 10 zhang long and 2.5 zhang wide; and the shen zhou (spirit ships) he sent on emissarial missions were reported to be three times as big. The ships of Khubilai Khan each had more than ten sails and were said to hold a thousand men. On the large lake west of Hangzhou, grand pleasure boats from the Song dynasty called Xihu zhou chuan (West Lake ships) were presumed to be more than 50 zhang long. They "were skillfully made with engraved railings and painted pillars. They moved through the water with great stability and made the passengers feel as if they were on dry land."

......Most of the drydocks at Longjiang were 90 to 120 feet wide, but two of them were 2 10 feet wide, big enough to accommodate a ship 160 to 166 feet wide.
......It is not clear just how many large treasure ships were among the fleet of 317 ships that the emperor assembled in Nanjing in the spring of 1405. As Ming novelist Lou Maotang suggests in San Bao taijian Xiyang ji tongsu yanyi, his sixteenth-century novel about Zheng He¹s voyages, there may have been only four such splendid boats for the eunuch commander and his principal -deputies.
....The second-largest boats were eight-masted "horse ships", some 339 feet long by 138 feet wide. These ships did, in fact, carry horses, which were an important part of the tribute trade, as well as other, tribute goods and all building materials necessary to repair the fleet at sea. The large holds of the seven-masted "supply ships"‹about 257 feet long and 115 feet wide-were packed with food staples for the crew, who numbered 28,000 on some voyages. Six-masted "troop transports"‹approximately 220 feet long and 83 feet at the beam‹were used to carry the treasure fleet¹s large contingent of soldiers. The fleet had two kinds of warships, five-masted, 165-foot-long fuchuan and smaller, faster-oared ships, some 120 or 128 feet in length, that terrorized pirates.
