Tongkang or "Tong'kang"[1] refers to several type of boats used to carry goods along rivers and shoreline in Maritime Southeast Asia.
[2]: 85 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.
A tongkang in full sail appeared on the reverse of the 1990 and 1992 Singapore dollar 2 $ currency notes.
These traditional vessels began to disappear around the 1930s, following the introduction of motor-powered boats and contemporary-type lighters.
