Sail
A sail is a tensile structure of fabric or another membrane that uses the wind to propel a craft; sailing boats appear on Cucuteni–Trypillian ceramics from the 6th millennium BCE, and excavations of the Ubaid period in Mesopotamia give direct evidence of them. When and where the sail was invented is not known. Sails are depicted in Egypt around 3200 BCE, on reed boats sailing up the Nile against its current. Austronesian crab claw sails, used with outriggers and catamarans, carried settlers from Taiwan as far as Polynesia and Madagascar.
