While the decline of Chinese sea power is often blamed on having to deal with the northern threat, there were limitations on Chinese ship design that would likely have led to the Chinese decline regardless.
And while many of extolled the sailing virtues of the Chinese ships, there are some indications that the traditional Chinese sailing ships might not have been as good as some have claimed.It was in the fifteenth century that differences of great importance emerged in local naval architectural practices. For around that time, development in Europe began to accelerate in response to unique social, economic and military pressures. In short order, European naval architecture ‘took off ’, and over a period of about three centuries followed a trajectory that placed European ships and seafarers in a position of absolute maritime supremacy over any non-European maritime civilization.

Meanwhile, in broadly unified and generally well-governed dynastic China,nothing similar occurred...........

The largest Chinese ships of the mid-nineteenth century had developed incrementally from vessels from a millennium before; they would have been familiarin almost all respects to a seafarer of that earlier epoch. If we ignore the highlycontentious, indeed technically extremely dubious, claims of the Zheng Hetreasure-ship boosters,34 it will have moved from being 20–30 metres in length to60–70 metres, and from 100 or so tons burthen to at most 1,500 tons burthen.35The unstayed, multi-single-tree-masted36 rigs barely changed, though over a900-year period the sails passed from conjoined panels of a sandwich of wovenrattan or bamboo and leaves, through panels of tightly woven rattan or bamboo,to battened, complete sails of a hemp- and flax-based canvas.

But it can be argued that outwith some truly major technical changes, for anyglimmerings of which there is no obvious historical evidence, the naval architecture that had evolved in China by the Ming dynasty (1368–1644) may havefaced some intrinsic limitations in its basic design envelope. In effect, the designand performance envelopes of the Chinese junk hull and rig had nearly identical boundaries, such that if there were demands for enhanced performance as aresult of competitive or other pressures, there may not have been any margin tospare without radical changes in materials and fastening technologies. By contrast, the scalability and adaptability of the Western design envelope createdlarger margins outside the initial performance envelope that could accommodateincreased performance demands. Simply put, among several design constraintsbuilt into the Chinese design envelope, two were arguably the most important.Given the system of transverse solid framing, it was difficult to increase internalcapacity by adding depth to the hull. Given the rig, it was difficult to add moredriving power—in the form of increased sail area—to propel a larger, heavierhull. The system that had evolved in the West, on the other hand, allowed theready development of multiple continuous decks in the hull. In the rig, by theaddition of topmasts and top gallant masts with further staying, more sail areacould be added to drive the larger hulls....."The East Sails West: The Voyage of the Keying 1846 - 1855" Stephen Davies. https://hkupress.hku.hk/pro/con/302.pdf
In the replica of a Chinese traditional sailing junk, the Princess Taping, which sank by being run over by a modern freighter, some posters who actually met some of the crew who had sailed under the captain of the Taiping had this to say:
The Princess Taiping inability to sail to intended ports due to some of the poor sailing characteristics of the traditional Chinese junk design is mirrored in the 19th century Chinese junk Keying having to divert from sailing to England as intended but sailed to New York instead after rounding the Cape of Good Hope. Since sailing to New York isn't really a shorter voyage from St. Helena than Britain, it implies that the sailing abilities of the Keying were not up to sailing to England directly. I don't recall ever reading of any European ship having to divert to North America instead of sailing to Europe as planned when they rounded the Cape.My comment: Your interest of how such ancient junk like ‘Princess Tai-ping’ wound behave in different point of sail and weather/wind conditions is admirable.Am I too bold to ask you what you have learned when you talked with ‘captain’ Liu about the sailing performance of ‘Princess Tai-ping’?
OK, you said that you didn’t like to mention it in your article (you didn’t like to bore the readers…) even though it presumably is the key to understand why ‘Princess Tai-ping’ had so many problems during her voyage.
Because of her sailing characteristics, her poor pointing ability, her extreme leeway, etc.?!
Why ‘Princess Tai-ping’ was not able to call Seattle as planed but ended up in Eureka? (Eureka!!!) Why did ‘Princess Tai-ping’ not sail straight from Okinawa to Keelung where she was expected to finish her voyage, but ended up east of Suau?
And why she was shipwrecked there?
Check the charts and the weather/wind conditions at the time if you still don’t get my point.
Anyhow, don’t you at least agree with me that a historic junk like ‘Princess Tai-ping’ is extremely difficult to sail? https://blog.hiddenharmonies.org/200...pacific-ocean/
While there was great advance in ship design in Europe from the 13th century to the 15th century, what major advance was there in Chinese ship design in the same period? European ships went from just square sails or just lateen sails to a combination of both square and fore/aft (lateen) sails, while we don't see similar evolution of the Chinese sail plans to the same extent.
PS - European ships back in the 13th century could be of a large size. The Genoese ship the Oliva was capable of carrying 1,100 passengers in 1248, and the a proposal in 1268 for hiring ships in the second crusade of King Louis IX took as standard a vessel capable of carrying 1,000 pilgrims. (The Hospitallers, the Mediterranean and Europe: Festschrift for Anthony Luttrel, Chapter 6 "Hospitaller Ships and Transportation Across the Mediterranean" David Jacoby. https://books.google.com/books?id=rI...201000&f=false ) The number of passengers given for these European ships were similar to those reported for the Chinese ships around a similar time frame.
