A fisherman repairs the sail of his wooden sailing boat, known as mashua, along the waterfront of Kisingitini, a natural harbour on Pate Island. Kisingitini is the centre of the island's fishing industry with crayfish being the fishermen's prized catch. The island is the largest of the Lamu Archipelago lying in the Indian Ocean just north of Lamu and 150 miles north-northeast of Mombasa.Dhow is the colloquial word used by most visitors for the wooden sailing ships of the East African coast although in reality a dhow is a much larger ocean-going vessel than either the medium sized Jahazi or smaller mashua fishing boats.
