Fu Chuan, also known as Fu Jian Chuan (福建船, lit. 'Fujian ship') and
Bai Cao (白艚, lit. 'White junk'), is a type of sailing ship originated
from
Fujian. It is the most widely used and well-known of the "Four Great Ancient Ships"
of China, and formed the backbone and workhorse of Ming navy.
Fu Chuan is an oceangoing sailing ship with a S-shaped hull with both high
sheer forward and high sheer aft, a flat prow without a stempost that appears
as a flat V-shape when viewed directly from the front, as well as a flat
stern. It is equipped with a retractable unbalanced rudder shaped like a tall
parallelogram, and has a deck that widens towards the stern. Fu Chuan's junk
sails are typically rectangular in shape. Unique to the ship type, some large,
oceangoing Fu Chuan are designed with the capability to quickly swap out
primary rudder with a smaller secondary one in order to traverse shallow
water, and many Fu Chuan are also fitted with mountings for additional Yuloh
sculling oar-cum-auxiliary rudder for more maneuverability.
While not as tough as
Guang Chuan (廣船), Fu Chuan is still sturdy enough to overpower most other types of warships
it will likely encounter. It is also cheaper and far more suitable for
offshore sailing than Guang Chuan (the deep V hull of Guang Chuan is less
stable and susceptible to rolling and banking, especially at lower speed),
making it a superior choice for a general purpose warship.
Classification of Fu Chuan
During Ming period military Fu Chuan were divided into six different classes
based on their size. Mark 1 and Mark 2, known simply as Fu Chuan or
Da Fu Chuan (大福船, lit. 'Great Fu Chuan'), were considered capital
ships. Mark 3 Shao Chuan (哨船, lit. 'Sentry ship') or
Cao Pie Chuan (草撇船, possible translation may be 'straw cushion
ship'), Mark 4 Dong Chuan (冬船, lit. 'Winter ship') or
Hai Cang Chuan (海滄船, lit. 'Haicang
ship') were medium-sized ships and served as mainline combat vessels. Mark
5 Niao Chuan (鳥船, lit. 'Bird ship') and Mark 6 Kuai Chuan
(快船, lit. 'Fast ship'), collectively known as Kai Lang Chuan (開浪船,
lit. 'Wave-cutting ship'), were the smallest classes, and served in a
scouting role. Nevertheless, this classification fell out of use by the tail
end of Ming Dynasty as older designs were supplanted by new generation of Fu
Chuan such as Gan Zeng Chuan (趕繒船, lit. 'Trawling net ship') and
Tong An Suo Chuan (同安梭船, lit. 'Tong'an
shuttle ship').
Da Fu Chuan (大福船)

A Fu Chuan has two decks and a superstructure built on its upper deck. The lowest level of the ship is used to store stones, bricks and roof tiles (as ballast). Next above is the berth deck where the accommodation for ship crew is located. Above the berth deck is the upper deck (topmost deck of a ship), which is almost entirely covered by an enclosed superstructure made of wooden planks and reinforced by bamboo. The superstructure is the primary fighting compartment of Fu Chuan, allowing soldiers to fight from inside it or on its battlemented roof (battlement is not depicted in the illustration above), although it also houses the ship's galley (kitchen) and drinking water storage, and both sails and anchors are operated from here as well.
At the Fu Chuan's stern, a three-storey tall aftercastle raises above the
superstructure. The bridge is most likely located here, as this arrangement
confers many advantages, namely it places the captain and the helmsman within
shouting distance of each other, allows the captain to have a full view of the
entire ship thus making tight turns much easier, and is sheltered from large
waves washing over entire ship deck during adverse weather.

Mark 5 Niao Chuan and Mark 6 Kuai Chuan, collectively known as Kai Lang Chuan,
are the smallest of the Fu Chuan class. They can be distinguished from their
larger cousins by their pointed (rather than flat) prow, hybrid sail-and-oar
propulsion (although oars were eventually phased out), and use of steering
oar. Too small to mount the protective superstructure of larger Fu Chuan, Niao
Chuan and Kuai Chuan make poor frontline combat vessels, although their speed
and maneuverability allow them to excel in harassing and scouting role. They
are also used to collect enemy heads from floating dead bodies after the
battle.
Transition to gun deck-based warship
For much of China's history, the principal Chinese warship design was the
so-called "tower ship"—a warship which primary fighting compartment is a large and enclosed
superstructure built on top of its hull. The design offers excellent
protection to ship crew and fully capitalises on the superior projectile
weapon technology (namely
crossbow,
trebuchet, and
gunpowder bomb) employed by the Chinese, not to mention increased height of the ship also
makes it less vulnerable to boarding.
Originally designed for riverine warfare between various Chinese warring
states, tower ship was so successful that it saw continuous use even after
more seaworthy hull designs were discovered and sails replaced oars as the
primary means of propulsion. Ming period Fu Chuan was essentially the 16th
century iteration of classical tower ship, and actually wouldn't look very
different from contemporary tower ship-equivalents such as Japan's atakebune (安宅船)
and Korea's panokseon (板屋船) save for the fact that it was smaller and more compact, lacked
the banks of oars of the other two, and had aftercastle in place of a
forward command tower. In fact, Ming tower ship was the direct inspiration
that led to the the creation of panokseon, and likely influenced the
development of Japanese warship as well.
Nevertheless, as Chinese shipbuilders began to mount more and
heavier guns
onto their warships, the primary weakness of tower ship, namely instability
caused by high centre of gravity, became increasingly intolerable. Echoing
similar development in Europe, Chinese war junks also underwent drastic
revamps and changed into a gun deck-based design. Gone was the tall
superstructure, and the primary fighting compartment of the new warship—its
gun deck—was now directly built into the hull. While it is difficult
to pin down the exact date when the transition began (it most likely
happened during very late 16th century or very early 17th century), the
process certainly took off with with resounding speed, as by early Qing
period virtually all Chinese war junks had changed into
the quintessential form still recognisable today, while tower ships all
but disappeared.

So what about the replica fuchuan at the start, is it the late Ming era or Qing era fuchuan replica? Is there any other camera angle for that replica?
ReplyDeleteClaimed to be Ming, but I have my doubt.
DeleteThis is a news page with the same ship during its WIP stage.

Where does the dimension came from? According to Wikipedia, Zheng He-era Fuchuan is about 50 m long
ReplyDeleteNo idea.
DeleteThere is no consensus about the size of Zheng He's ship. 50m seems small though as there were Fengzhou larger than that.
Will you discuss/post about Zheng He's fleet ships in the future? Such as baochuan, machuan, liangchuan, bingchuan, fuchuan (but those in the fleet), zuochuan and shuichuan?
DeleteNot in the plan right now, but eventually I will cover it as I learn more about them...I guess.
DeleteThere is an interesting paper by Andre Wegener Sleeswyk titled "The Liao and the Displacement of Ships in the Ming Navy" that attempts to re-evaluate the size of Cheng Ho's ships. There are references to Cheng Ho's fleet including ships of 2,000 liao and 1,500 liao on surviving stelae. Sleeswyk started with determining what a liao was based on Li Chao-hsiang's writings about the ships built at Lung-chiang ch'uan-ch'ang. His conclusion is that the liao is a measurement of volume/displacement (length x beam x height)^(2/3), with each of those measurements in ch'ih. Sleeswyk believes the author of Ming Shih excluded height for some reason and treated the liao as if it was just length x beam, multiplying the size of the ships significantly. Sleeswyk's conclusion is that the bao chuan was roughly 199 ch'ih (62 meters) in length, the ma chuan around 165.5 ch'ih (51.7 meters), and the fu chuan 80.5 ch'ih (25.2 meters), and that a liao is roughly half a modern ton of displacement.
Delete@Stephen
Delete62 m seems pretty in line with a 2,000 liao ship.
Sleeswyk's paper was written in 1996 I wager? The discovery of the grave of Hong Bao (a eunuch that participated in the voyage) in 2010 upped the size of Bao Chuan to 5,000 liao, so the current estimate is 75~84 m.
