Dhow 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, says Wikipedia.
Some historians believe the dhow was invented by Arabs but this is disputed by others.[1][2]
Dhows typically have a long, thin hull design. They are trading vessels primarily used to carry heavy items, like fruit, fresh water or merchandises, along the coasts of the Arabian Peninsula, Pakistan, India, Bangladesh and East Africa.
Larger dhows have crews of approximately thirty people, while smaller dhows typically have crews of around twelve or three.
