Answer:
Boats of the Neolithic era were very simple. They were essentially rafts, made of easy to find materials such as wood.
In the Neolithic, there were many cultures that built boats, and sailed across the sea, but mostly for relatively short distances. Interoceanic navigation was essentially null.
Boats of the modern era have evolved a lot. From sailing boats, to large rowing boats like the Viking longships, to mechanical boats of the modern era. This evolution is to be expected since boats are among the first human inventions in history, dating back to thousands of years before the Neolithic Revolution.
