Arabian Dhows (Single-Masted Sailboats)

Timeline

1. 800–1500Arabian Sea · Arabian SeaAgainst the backdrop of the expansion of Islamic caliphate empires, dhows became the principal merchant vessels linking Basra, Aden, Malindi, and Calicut, carrying ceramics, cloth, spices, and slaves; Muslim merchants established stable annual shipping cycles based on the monsoon pattern.
2. 1498–1610Western Indian Ocean · Indian OceanAfter the Portuguese fleet arrived in 1498, they established the cartaz permit system in the Indian Ocean, forcing dhows to pay tolls or face bombardment. By the early seventeenth century (1601–1610), Arab and Indian merchants still used dhows to maintain trade between coastal ports where Portuguese control was weak, and the two sides formed a pattern of competitive coexistence.
3. 1800Oman, Zanzibar, Red Sea · Arabian PeninsulaEven after steamships became widespread, dhows continued in coastal trade in Oman, Kenya, Zanzibar, and elsewhere into the twentieth century; they are a living symbol of Indian Ocean maritime cultural heritage, with annual coastal trading voyages still using traditional hull types and sailing methods.
