Arab Single-Masted Sailboat

Timeline

1. 600–1000Red Sea and Indian Ocean · Arabian SeaArab and Persian merchants used the monsoons to travel between East Africa, India, and Southeast Asia. The single-masted sailboat's long, shallow-draft hull suited coastal and near-ocean voyages, and combined with the monsoon sailing regime it formed a stable annual trade cycle.
2. 1000–1300Hormuz and the Malabar Coast · West coast of the Indian OceanIndian Ocean trade flourished unprecedentedly from the 11th to 13th centuries. Single-masted sailboats grew in size, capable of carrying heavy cargo across the Arabian Sea directly to India's west coast and the Swahili coast of East Africa, forming a complementary ocean-going sailing ship system with Hanseatic cogs and Chinese fuchuan in their respective seas.
3. 1211–1368Calicut and Quanzhou · KozhikodeAfter the Mongol Empire unified the overland Silk Road in the 13th century, maritime trade became more important. Arab single-masted sailboats exchanged goods with Chinese sailing ships at Calicut, Hormuz, and elsewhere, and spices and porcelain were transshipped via this vessel type to the Red Sea and the entrance to the Mediterranean.
4. 1400–1500Oman and the East African coast · OmanAfter Portuguese fleets entered the Indian Ocean, traditional single-masted sailboats turned to coastal and archipelagic routes under military pressure, but remained in long use in Oman, East Africa, and the Southeast Asian archipelago, giving rise to various local variants; similar vessel types still exist in some waters today.
