Question

How did the ship industry begin and how is it at present ?

Answer 1

around 4000 BC the Egyptians said rather that drag this stuff lets build a raft and let current and wind push us.

around 2000 BC the Phoenicians said if we put sides on this raft to keep the water out we can go out in the ocean.

in 2006, 75,000 20 foot containers were unloaded or loaded EVERY DAY in the US.

95 % of the world's trade goes by sea.
