Transport through Water
At first man might have moved through water clinging to a log and paddling along with his hands and feet.
The early boat was made by burning the inside of a tree trunk and chipping away the charred wood. This was made to move through water with the help of oars.
As centuries passed, the single-masted sailing ship changed to the three-masted type of the 15th Century AD, and latter to the fully-rigged ship of the 18th and 19th Centuries AD.
