From rafts to ocean liners

We don’t know exactly how the first human transportation over water happened. But it’s not hard to imagine how it might have come about.

Long ago, people used anything that would float to move things across water—bundles of reeds, even jars and covered baskets.

Perhaps one day someone tied three or four logs together. This made a raft. Maybe someone else hollowed out a log as a kind of canoe. These log boats could be moved by people paddling with their hands. Later they might have used a stick or a pole to make their boat move faster.

Whoever put the first sail on a boat made a wonderful discovery. Sailing was faster and easier than paddling because it caught the wind and made it do the work.

Eventually, someone built a ship that used a sail and long paddles, called “oars.” When there was little or no wind, the sailors rowed with the oars. In time, sailors learned to turn, or “set,” a sail to make the boat go in almost any direction they wished.

Paddles began to be used again much later in giant wheels that moved large boats through the water. A steam engine powered these paddle wheels, which were too heavy to turn by hand. Steamboats cruised rivers, lakes, and oceans all over the world.

Today ships and boats use many different kinds of engines. Most ships use oil to generate power. Some submarines run on nuclear power. But on warm days, many people still enjoy traveling on water by paddling, sailing, and even rafting.
