Toop (also known as toup, prauw toop or perahu toop) is a type of boat-ship produced in East Indies. Appeared at the end of the 18th century, and built in local shipyards, this type of boat is one of the results of the incorporation of 'Western' and 'Nusantaran' technologies that began in the shipyards of the 17th and 18th European trading companies. This type of boat is commonly used for long-distance shipping. In the first half of the 19th century, this was the most common type of boat used by sailors and traders in Nusantara. Majority of toop is owned by merchants from the western area of Nusantara.
