History of Ships and Water Transportation:

History of Ships and Water Transportation History and Hull Design

The Early Days:

The Early Days Most likely the earliest form of water transportation was a single log found floating in the water. Later, groups of logs might be lashed together into a crude raft. These were utilized well into the 20 th century.

Archimedes’ Eureka Moment:

Archimedes’ Eureka Moment Archimedes of Syracuse ( c. 287 BC – c. 212 BC) was a Greek mathematician , physicist , engineer , inventor , and astronomer . Although few details of his life are known, he is regarded as one of the leading scientists in classical antiquity . The story goes that he was sitting in the bath tub one day when he had an epiphany.

Archimedes Bathtub:

Archimedes Bathtub Archimedes noticed that when he got into the tub, the water level rose. He determined from this fact that the density of a body determined how much water it would displace. This is why even huge steel aircraft carriers will float and tiny steel balls won’t. The ship has much more airspace inside and so is much less dense. Archimedes used this discovery to determine the guilt of a dishonest goldsmith who was supposed to make a crown of pure gold for the king. He measured the density of the crown by placing it in water and seeing how much was displaced. He then put the same amount of pure gold in the water and found that it displaced more water. What ever the crown was made of, it was not pure gold.

Ship Building:

Ship Building Evidence suggests that the Egyptians were lashing planks into ship hulls as early as 3000 BC. Apparently they used reeds and grasses to form straps to hold their ships together. By 2500 BC, harbors and port cities were beginning to appear around the Mesopotamian region and in India.

No More Rowing:

No More Rowing Evidence of masts and sails have been found among relics of Egypt’s 18 th dynasty. By this time, trade along coastlines is well established but little offshore navigation can occur until a way is found to navigate without landmarks.

Asia:

Asia In Asia, the Chinese were building “castle barges” with heavily fortified decks to carry soldiers and weapons. Over time these evolved into the traditional Chinese “junks” and the design is still in common use today.

Iron-clads:

Iron- clads Finally in 1843, the Great Britain of Isambard Kingdom Brunnel was the first ship whose hull was fabricated entirely of iron. Interior bulkheads and steel construction replaced iron in the later half of the 19 th century paving the way for the modern shipbuilding practices of today.

Bigger is Better:

Bigger is Better Today super tankers and cargo vessels are bigger than anything the ancient world could have imagined. Oil carriers can be over 1000 ft long and can carry over 3 million barrels of oil.
