Djong

The djong, jong, jung, or original junk is a type of sailing ship originating from Java that was widely used by Javanese sailors. The word was and is spelled jong in its languages of origin, the "djong" spelling was a colonial Dutch romanization. In English, the jong lends its name to other ships of similar configuration, called junks, and to their characteristic style of rigging, the junk rig. Jongs are used mainly as seagoing passenger and cargo vessels. They traveled as far as the Atlantic Ocean in the medieval era. Their tonnage ranged from 40 to 2000 deadweight tons, with an average deadweight of 1200–1400 tons during the Majapahit era. Javanese kingdoms such as Majapahit, Demak Sultanate, and Kalinyamat Sultanate occasionally used these vessels as warships, but they were still predominantly transport vessels. The Mataram Sultanate primarily used jongs as merchant ships rather than warships.
