How did Vikings make the ships?
They were built beside a river, a tall oak tree would make the keel and long planks of wood were used for the sides. They used wooden pegs and iron rivets to to screw the pieces together. Animal wool and sticker par from pine trees were stuffed in between every joint to keep the water out. Instead of using saws they used axes. Pitch’ was painted on the wood to make it waterproof
. When the ship were to be launched they pushed it over log rollers and into the water.
