Development From Log to Clipper Part II
Skin boats were used where vegetable material was lacking; in the Artic and desert Arabia. Rush canoes were built of bullrushes or papyrus around the Pacific, Africa, the Persian Gulf , Peru and Bolivia. Coracles or circular baskets from the Tigris and Nile were made large enough to transport horses. Another development was rafts, sometimes with sails and platforms with outriggers set to leeward or windward. Dugouts gave way to planked boats through sown washboards. Paddle development from hands was obvious but sails did not evolve spontaneously in many lands.
