The sail boats used along the Nile are called felucca; they’re also common around Malta, Tunisia, Sudan and Iraq. Wooden hulls and masts lead to one or two lateen sails. Felucca can typically carry 10 passengers with 2 or 3 crew. They remain popular in Egypt but mainly for tourists, which may explain the presence of the aeroplane on this stamp (another stamp from the same series features a silhouetted plane flying over assorted pyramids, but I’ll save that for another day).
I should probably be referring to classics of Roman literature and the exploits of the Pharoahs, but for me, this just sends me into a hybrid of Death On The Nile, The Mummy, Thy Spy Who Loved Me and assorted Indiana Jones movies….
