Dhow with lateen sail in "bad tack" with the sail pressing against the mast, in Mozambique. The emergence of new evidence for the development and spread of the lateen sail in the ancient Mediterranean in recent decades has led to a reevaluation of the role of Arab seafaring in the Indian Ocean, replacing a belief that this sail has an eastern origin.
