Ancient Egyptians used which wood to build their boats?

Eventually, the Egyptians began to make boats from wood. They used acacia wood from Egypt and imported cedar wood from Lebanon. They also began to use a giant sail in the middle of the boat so they could catch the wind when heading upstream. The Egyptians built their wooden boats without nails. Boats were often made from a number of short planks that were hooked together and tied tight with ropes. Steering was accomplished by using a large rudder oar at the back of the ships.
