A group of Nakhodas (captains) smoking water pipe at the Iranian city of Kong. There is only a handful number of Nakhodas still alive who used to travel with sail boats before they give their place to the boats with engine. The transition occurred gradually over the 50s and 60s. By the 70s, most of the boats had either both sail and engine or only engine. By putting sail boats aside, extremely invaluable sailing knowledge was put in danger.
