Felucas are common on the Nile in Egypt. The wooden sailing boat is moved by the wind. It seems to take two men to control the sail and the rudder. Many Nubians find work running these boats. See here. The photo below was made at Aswan, Egypt. Aswan is known as Syene in Ezekial 29:10 and 30:6.
Kitchener’s Island is visible on the left, and Elephantine Island is on the right.
Whether at Aswan or Cairo, an afternoon ride aboard a feluca is a pleasant and relaxing experience.
