A boat is a watercraft of any size designed to float or plane, to provide passage across water. Usually this water will be inland (lakes) or in protected coastal areas. In naval terms, a boat is a vessel small enough to be carried aboard another vessel (a ship). Another less restrictive definition is a vessel that can be lifted out of the water. Boats have served as short-distance transportation since early times. They  were used between 4000 BCE and 3000 BCE in Sumer, ancient Egypt and in the Indian Ocean. The oldest recovered boat in the world is the Pesse canoes. However, we will pass all the definitions and this time we wont mention all the expensive ones but  we will  present you some of the most unusual and unique boats.
