Junk (ship)
Encyclopedia
A junk is an ancient Chinese
sailing vessel design still in use today. Junks were developed during the Han Dynasty
(206 BC–220 AD) and were used as sea-going vessels as early as the 2nd century AD. They evolved in the later dynasties, and were used throughout Asia
for extensive ocean voyages. They were found, and in lesser numbers are still found, throughout South-East Asia and India
, but primarily in China
, perhaps most famously in Hong Kong
. Found more broadly today is a growing number of modern recreational junk-rigged sailboats.

s that sailed long distances as early as the 2nd century AD. They incorporated numerous technical advances in sail plan and hull designs that were later adopted in Western shipbuilding.
The historian H. Warington Smyth considered the junk one of the most efficient ship designs, stating that "As an engine for carrying man and his commerce upon the high and stormy seas as well as on the vast inland waterways, it is doubtful if any class of vessel… is more suited or better adapted to its purpose than the Chinese or Indian junk, and it is certain that for flatness of sail and handiness, the Chinese rig is unsurpassed."
make the junk easy to sail, and fast. Unlike a traditional square rig
ged ship, the sails of a junk can be moved inward, toward the long axis of the ship, allowing the junk to sail into the wind.
The sails include several horizontal members, called "batten
s", which provide shape and strength. Junk sails are controlled at their trailing edge by lines much in the same way as the mainsail on a typical sailboat, but in the junk sail each batten has a line attached to its trailing edge where on a typical sailboat a single line (the sheet) is attached only to the boom. The sails can also be easily reefed and adjusted for fullness, to accommodate various wind strengths. The battens also make the sails more resistant than traditional sails to large tears, as a tear is typically limited to a single "panel" between battens. Junk sails have much in common with the most aerodynamically efficient sails used today in windsurfers or catamaran
s.
The standing rigging
is simple or absent.
The sail-plan
is also spread out between multiple masts, allowing for a powerful sail surface, and a good repartition of efforts. The rig allows for good sailing into the wind.
Flags were hung from the masts to bring good luck and women to the sailors. A legend among the Chinese during the junk's heyday regarded a dragon which lived in the clouds. It was said that when the dragon became angry, it created typhoons and storms. Bright flags, with Chinese writing on them, were said to please the dragon. Red was best, as it would induce the dragon to help the sailors.

), so that the boat relies on a daggerboard

or very large rudder to prevent the boat from slipping sideways in the water. The largest junks, the treasure ship

ships, and, due to its well-balanced design, allowed adjustment according to the depth of the water. A sizable junk can have a rudder that needs up to three members of the crew to control in strong weather. The world's oldest known depiction of a stern-mounted rudder can be seen on a pottery model of a junk dating from before 1st century AD, though some scholars think this may be a steering oar - a possible interpretation given that the model is of a river boat that was probably towed or poled.
From sometime in the 13th-15th centuries, many junks began incorporating "fenestrated" rudders (rudders with holes in them), probably adopted to lessen the force needed to direct the steering of the rudder.
The rudder is reported to be the strongest part of the junk. In the Tiangong Kaiwu "Exploitation of the Works of Nature" (1637), Song Yingxing
wrote, "The rudder-post is made of elm, or else of langmu or of zhumu." The Ming author also applauds the strength of the langmu wood as "if one could use a single silk thread to hoist a thousand jun or sustain the weight of a mountain landslide."
, strengthened the ship and slowed flooding
in case of holing. Ships built in this manner were written of in Zhu Yu's
book Pingzhou Table Talks, published by 1119 AD during the Song Dynasty
. Again, this type of construction for Chinese ship hulls was attested to by the Moroccan Muslim Berber
traveler Ibn Batutta (1304-1377 AD), who described it in great detail (refer to Technology of the Song Dynasty
). Although some historians have questioned whether the compartments were watertight, most believe that watertight compartments
did exist in Chinese junks. All wrecks discovered so far have limber hole
s; these are different from the free flooding holes that are located only in the foremost and aftermost compartments, but are at the base of the transverse bulkheads allowing water in each compartment to drain to the lowest compartment, thus facilitating pumping. It is believed from evidence in wrecks that the limber holes could be stopped either to allow the carriage of liquid cargoes or to isolate a compartment that had sprung a leak.
Benjamin Franklin
wrote in a 1787 letter on the project of mail packets between the United States and France:
In 1795, Sir Samuel Bentham
, inspector of dockyards of the Royal Navy
, and designer of six new sailing ships, argued for the adoption of "partitions contributing to strength, and securing the ship against foundering, as practiced by the Chinese of the present day". His idea was not adopted. Bentham had been in China in 1782, and he acknowledged that he had got the idea of watertight compartments by looking at Chinese junks there. Bentham was a friend of Isambard Brunel
, so it is possible that he had some influence on Brunel's adoption of longitudinal, strengthening bulkheads in the lower deck of the SS Great Britain
. Bentham had already by this time designed and had built a segmented barge for use on the Volga River, so the idea of transverse hull separation was evidently in his mind. Perhaps more to the point, there is a very large difference between the transverse bulkheads in Chinese construction, which offer no longitudinal strengthening, and the longitudinal members which Brunel adopted, almost certainly inspired by the bridge engineering in which he and his contemporaries in iron shipbuilding innovation were most versed.
Due to the numerous foreign primary sources that hint to the existence of true watertight compartments in junks, historians such as Joseph Needham
proposed that the limber holes were stopped up as noted above in case of leakage. He addresses the quite separate issue of free-flooding compartments on pg 422 of Science and Civilisation in Ancient China:
s and centerboards, used to stabilize the junk and to improve its capability to sail upwind, are documented from a 759 AD book by Li Chuan. The innovation was adopted by Portuguese and Dutch ships around 1570. Junks often employ a daggerboard that is forward on the hull which allows the center section of the hull to be free of the daggerboard trunk allowing larger cargo compartments. Because the daggerboard is located so far forward, the junk must use a balanced rudder
to counteract the imbalance of lateral resistance.
Other innovations included the square-pallet bilge pump
, which was adopted by the West during the 16th century for work ashore, the western chain pump, which was adopted for shipboard use, being of a different derivation. Junks also relied on the compass
for navigational purposes. However, as with almost all vessels of any culture before the late 19th century, the accuracy of magnetic compasses aboard ship, whether from a failure to understand deviation (the magnetism of the ship's iron fastenings) or poor design of the compass card (the standard drypoint compasses were extremely unstable), meant that they did little to contribute to the accuracy of navigation by dead reckoning.

The dimensions of Zheng He's ships according to ancient Chinese chronicles are disputed by modern scholars (see below):
Some recent research suggests that the actual length of the biggest treasure ships may have been between 390–408 ft (118.9–124.4 m) long and 160–166 ft (48.8–50.6 m) wide, while others estimate them to be 200–250 ft (61–76.2 m) in length.

, sailed from China around the Cape of Good Hope
to the United States and England between 1846 and 1848. Many junks were fitted out with carronades and other weapons for naval or piratical uses. These vessels were typically called "war junks" or "armed junks" by Western navies which began entering the region more frequently in the 18th century. The British, Americans and French fought several naval battles with war junks in the 19th century, during the First Opium War

In 1955, six young men sailed a Ming Dynasty
-style junk from Taiwan
to San Francisco. The four-month journey aboard the Free China was captured on film and their arrival into San Francisco made international front-page news. The five Chinese-born friends saw an advertisement for an international trans-Atlantic yacht race, and jumped at the opportunity for adventure. They were joined by the then US Vice-Consul to China, who was tasked with capturing the journey on film. Enduring typhoons and mishaps, the crew, having never sailed a century-old junk before, learned along the way. The crew included Reno Chen, Paul Chow, Loo-chi Hu, Benny Hsu, Calvin Mehlert and were led by skipper Marco Chung. After a journey of 6000 miles (9,656 km), the Free China and her crew arrived into San Francisco Bay under a majestic fog on August 8, 1955. Shortly afterward the footage was featured on ABC television's Bold Journey travelogue. Hosted by John Stephenson and narrated by ship's navigator Paul Chow, the program highlighted the adventures and challenges of the junk's sailing across the Pacific, as well as some humorous moments aboard ship.
In 1959 a group of Catalan
men, led by Jose Maria Tey, sailed from Hong Kong
to Barcelona
on a junk named Rubia. After their successful journey this junk was anchored as a tourist attraction at one end of Barcelona harbor, close to where La Rambla
meets the sea. Permanently moored along with it was an alleged reproduction of Columbus' caravel "Santa Maria" during the 1960s and part of the 1970s.
In 1960 Lt. Col. Herbert George "Blondie" Hasler, (Herbert Hasler
), DSO, OBE, (27 February 1914 – 5 May 1987) sailed in the first Observer Single-handed Transatlantic Race (OSTAR) from Plymouth to New York. His yacht was a modified Folkboat, called Jester, which at 25 feet (7.6 m) , was one of the smallest boats in the race.
The Jester relied on a junk rig
to reduce the physical effort of handling a conventional rig single-handed. Safety was also increased as the junk rig enabled all sail-handling to be completed from the safety of a central control hatch. Hasler realised that he could sail Jester across the Atlantic without ever leaving the cabin. Hasler in Jester finished second, taking 48 days to cross the Atlantic.
In 1968, Bill King sailed a junk schooner in the controversial Sunday Times Golden Globe Race
.
A growing number of designs of modern recreational junk-rigged sailboats has emerged, such as Benford Design Group's Badger known from Annie Hill
's book Voyaging on a Small Income. Tom MacNaughton of MacNaughton Group also has several popular junk rigged designs.
For long travels with few crew, the simplicity of the junk rig in terms of construction, maintenance and handling makes it an important alternative to more prevalent designs. Most notably the safety that follows from extremely simple reefing, which is particularly important with few crew and deteriorating conditions, minimizes the need to work on deck while exposed to bad weather. Simple construction means lower cost and simpler repairs.

to San Francisco. The four-month journey aboard the Free China was captured on film and their arrival into San Francisco made international front-page news. The five Chinese-born friends saw an advertisement for an international trans-Atlantic yacht race, and jumped at the opportunity for adventure. They were joined by the then US Vice-Consul to China, who was tasked with capturing the journey on film. Enduring typhoons and mishaps, the crew, having never sailed a century-old junk before, learned along the way. The crew included Reno Chen, Paul Chow, Loo-chi Hu, Benny Hsu, Calvin Mehlert and were led by skipper Marco Chung. After a journey of 6000 miles (9,656 km), the Free China and her crew arrived into San Francisco Bay under a majestic fog on August 8, 1955. Shortly afterward the footage was featured on ABC television's Bold Journey travelogue. Hosted by John Stephenson and narrated by ship's navigator Paul Chow, the program highlighted the adventures and challenges of the junk's sailing across the Pacific, as well as some humorous moments aboard ship.

For long travels with few crew, the simplicity of the junk rig in terms of construction, maintenance and handling makes it an important alternative to more prevalent designs. Most notably the safety that follows from extremely simple reefing, which is particularly important with few crew and deteriorating conditions, minimizes the need to work on deck while exposed to bad weather. Simple construction means lower cost and simpler repairs.
