It has large square stern which projects at the sides of the hull and supported by two strong beams. On the side of the vessel are projecting open galleries for oarsmen.[1] Bajak has two mast with lug rig, and a bowsprit which support headsails (fore staysail and jib). The sail of bajak is made of cotton.[2] It has a large deckhouse between the foremast and mainmast, a hatchway is present abaft the mainmast.[1] The name may have originated from Malay word bajak means "plow", or membajak, "to plow".[3]Шаблон:Rp This prahu may have been used by Sea Dayak for use in piracy owing to its double type of propulsion (sail and oar) which is very common amongst pirate prahu of the region, and may have influenced the Javanese word bajak, which means hijack or piracy. Javanese word bajak laut means sea pirate.[4]Шаблон:Rp
