From rowing boats to nuclear powered boats, the modes of propelling and constructing boats have changed over time. .
Paddle Power: .
The earliest proof of boats using paddle power was in an Egyptian illustration dated around 5000 B.C. This boat was made of papyrus reed and was propelled by two paddles. Although this is the first solid record of a rowing boat, many people believe that boats were being propelled by paddles long before.
Many boats still us paddles and oars as a type of propulsion and also nearly all small motorboats have paddles in case their engines fail.
Some of the types of boats that use paddles/oars for power and a brief description:.
Coracle: A small rounded boat made of animal skins stretched over a bowl shaped framework. It is very light and easy to carry. It is powered by one person with a paddle and is still in use today.
Raft: A group of logs lashed together to form a floating platform that can seat lots of people and can also carry cargo. Some rafts are/were propelled by either a few people paddling on both sides or a sail/s.
Dugout: A dugout was a log that was carefully hollowed out by using either small controlled fires or by slowly scraping out a hole. They were powered by one or two paddles and could hold several people but not as many as a raft.
.
Sail Power: .
The earliest evidence of sail powered vessels is dated around the same time as that of paddle power. Most of the boats in the Middle Ages and ancient times were powered by oar/paddle, sail or a hybrid version where there is both a sail and oars are used. .
By harnessing wind power ships are able to travel long distances faster without as much manpower involved. .
Because sail power does not use fuel some modern ships have been designed with computer-controlled sails (to get the most out of them as possible) effectively halving the fuel consumption on journeys. .
