This small boat is a familiar site in the East. It has a relatively flat bottom, and can be propelled with a single sail or oars, or even with poles in shallow water. Given their small size and low profile, sampans are generally used close to land. They are commonly used for fishing as well as for transporting small groups of passengers or amounts of cargo. Sometimes the owner of a sampan erects a small shelter over part of the deck, leading to them being used as floating domiciles in certain areas. In this way the model presented can be used as something of a template for larger vessels or ones that have more elaborate structures built onto them.
The deck plan below is sized so that it can be printed and cut out for use with miniatures or other figures on the tabletop.
