Traditional dhows at Lamu island, Kenya. During low tide the dhows are being maintained, loaded and/or unloaded. They have been used for trading, transportation and fishing for centuries, and can easily cross the Indian Ocean to Arabia and India during the Monsoon. Besides a fast growing tourist industry, Lamu benefits from the export of Mangrove poles, oil seeds and various grains, and the dhows on returning home, bring back silks, spices and porcelain from abroad.
