A chialoup (or chaloup) was a type of sloop used in the East Indies, a combination of western (Dutch) and Nusantaran (Indonesian) technologies and techniques. Many of these "boat-ships" were produced by VOC shipwrights in Rembang and Juwana, where the majority of the workers were local Javanese. Chialoups were used by the Dutch East India Company and private merchant-sailors of western and Nusantaran origin.
