Dhow (Arabic داو dāw) is the generic name of a number of traditional sailing vessels with one or more masts with lateen sails used in the Red Sea and Indian Ocean region. Historians are divided as to whether the dhow was invented by Arabs or Indians. Typically sporting long thin hulls, dhows are trading vessels primarily used to carry heavy items, like fruit, fresh water or merchandise, along the coasts of Eastern Arabia (Arab states of the Persian Gulf), East Africa, Yemen and coastal South Asia (Pakistan, India, Bangladesh). Larger dhows have crews of approximately thirty, smaller ones typically around twelve.
The exact origins of the dhow are lost to history. Most scholars believe that it originated in India between 600 BC to 600 AD Some claim that the sambuk, a type of dhow, may be derived from the Portuguese caravel.
The Yemeni Hadhrami people, as well as Omanis, for centuries came to Beypore, in Kerala, India for their dhows. This was because of the good timber in the Kerala forests, the availability of good coir rope, and the skilled carpenters who specialized in ship building. In former times, the sheathing planks of a dhow's hull were held together by coconut rope. Beypore dhows are known as 'Uru' in Malayalam, the local language of Kerala. Settlers from Yemen, known as 'Baramis', are still active in making urus in Kerala.
In the 1920s, British writers identified Al Hudaydah as the center for dhow building. Those built in Al Hudaydah were smaller in size, and used for travel along the coasts. They were constructed of acacia found in Yemen.
