There are no engines on board our Dahabiya boats; they are designed for sailing the Nile. Due to the prevailing wind, more sailing is possible upstream towards Aswan than downstream towards Esna. Even the ancient hieroglyphs show this: a boat with a sail is sailing south (=upstream), a boat with oars is heading north (=downstream). Luckily each of our Dahabiya has its own small tug that can help if the natural elements fail.
