Tongkang

Tongkang is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Tongkang rather than just read about it. In short: A tongkang is a boat used to carry goods along rivers and shores in Maritime Southeast Asia. One of the earliest written records of tongkangs is in the Malay Annals, which was composed no earlier than the 17th century.

Key takeaways

  • Tongkang belongs to science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Tongkang to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Tongkang from memory before moving on to harder problems.

Reference excerpt

A tongkang is a boat used to carry goods along rivers and shores in Maritime Southeast Asia. One of the earliest written records of tongkangs is in the Malay Annals, which was composed no earlier than the 17th century. One passage mentions them being used by the Majapahit Empire during the 1350 attack on Singapura.

Etymology Because the majority of tongkangs were built, used, and manned by Chinese people, it is frequently assumed that the name was Chinese word. In fact, tongkang is certainly a Malay word, and probably derived from bĕlongkang (properly pĕrahu bĕlongkang, a pĕrahu jalur with strakes added to increase the freeboard), a word which was formerly used in Sumatra for a river cargo boat.

Description The tongkang was an unmotorised open cargo boat, propelled by a variety of methods, including rowing, punt poles and sail. The early tongkangs were about 20 ton burthen or less; they were propelled by about ten rowers and guided by a steersman. Long punt poles were used to propel them in shallower water. The size of the tongkang increased around 1860. The tongkang was one of the two traditional Malay ships using junk rig with local hulls instead of the Chinese Junk hull. Its hull design was more reminiscent of the dhow type used in South Asia and Western Asia than to the common Chinese or Far-eastern type. Besides the Junk Rig, the ketch rig was also used on the tongkang. The last tongkangs in Singapore were towed by a motorised launch.

Types of tongkang

Because the term "tongkang" is applied to several type of boats, the description of each boat is not necessarily the same.

Malaya Tamil-manned lighter, brought to Singapore in the 1820s. The old Singapore sailing lighter. Originally the Tamil-manned lighter, brought to Singapore in the 1820s. Later a western-style lighter hull, double-ended, usually with a single mast setting a large loose-footed dipping lugsail, and frequently manned by Chinese. These latter boats still survive, but they are no longer propelled by sails. Tongkang tunda, meaning "towed tongkang". European-style lighter hull, double-ended, usually with a single mast setting a large loose-footed dipping lugsail, and frequently manned by Chinese. These boats still survive, but they are no longer propelled by sails. Hull length is 50–80 feet (15–24 m). Tongkang Melayu, manned by Malays. Typically a double-ended lighter hull, ketch-rigged with standing gaffs and two headsails. No stern gallery and a western style rudder. Some had transom sterns. The hull length is 30–75 feet (9.1–22.9 m). Penang sailing lighter. Western-style lighter hull, with a transom stern and 1 mast with a large loose-footed dipping lugsail and a single headsail, or a bermuda-headed mainsail and one headsail. Formerly also double-ended, generally with 2 masts, setting a large lugsail on the mainmast. No stern gallery and a western style rudder. Normally manned by men from southern India. Hull length is 50–80 feet (15–24 m). Singapore timber tongkang. A heavy, wide hull with a transom stern, 2 masts and with a long bowsprit. They are ketch-rigged with standing gaffs, no topsails, two or three headsails. A stern gallery and Chinese rudder. Manned by Chinese. Hull length is 85–95 feet (26–29 m). Singapore trader: General purpose trading boat, now used mostly for carrying firewood. Hull similar to Singapore timber tongkang, but less beamy: stepping two or three masts, each setting a single highpeaked Chinese junk sail. Manned by Chinese. Hull length: 40–85 feet (12–26 m).

Brunei Tongkang. Manned by Malays. Medium-sized, double-ended cargo boat, decked fore and aft, with a deckhouse amidship. It has a stern gallery and 1 mast, setting a square-sail or a dipping lug. Built at Sepitang and Brunei. The local cargo-carrier of Labuan Bay, occasionally found as far north as Jesselton. Hull length: 30–40 feet (9.1–12.2 m).

North Borneo Tongkang Melayu. Western-style hull with transom stern, had 1 or 2 masts, each setting a large dipping lugsail. No bowsprit, usually one headsail. Steered with an unpierced rudder. This boat, which is used for collecting firewood in Sandakan Bay, is very similar to the transom-stern Penang Lighter in broad outline, though rather beamier. It is made by Banjars (Malays) on Nunuyan Laut Island, in Sandakan Bay. Hull length: 40–50 feet (12–15 m). Tongkang China. The name used in the North Borneo ports for visiting Chinese junks (usually arriving from Hongkong).

Tongkangs in Singapore

Tongkangs were actively used in Singapore. For example, an area around Read Bridge was known as "Cha Chun Tau" (Chinese: 柴船頭; Pe̍h-ōe-jī: Chhâ-chûn-thâu; lit. 'jetty for boats carrying firewood'), in reference to small tongkangs carrying firewood from the Indonesian archipelago that berthed there. The firewood trade was primarily a Teochew enterprise. A tongkang in full sail appeared on the reverse of the 1990 and 1992 Singapore dollar 2 $ currency notes. Tongkang LRT station was named after this boat. Another boat used on the Singapore River along with the tongkang was the twakow. These traditional vessels began to disappear around the 1930s, following the introduction of motor-powered boats and contemporary-type lighters.

Worked examples

Example 1 — a first encounter with Tongkang

Start with the simplest possible case. Write down what Tongkang claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Tongkang before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Tongkang ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Tongkang

In research
Tongkang appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Tongkang in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Tongkang is common in secondary-school and first-year university syllabi. It links to neighbouring topics 14th-century ships, Boat types, Malaysian inventions, so understanding it makes those chapters shorter.
In everyday life
Look for Tongkang outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
