Ship are made for traveling and exploring on sea. Some ship sink because of the rough water and because of rocks/icebergs.
S.s Titanic was the finest ship in it's day but. The Titanic died a few day later after it left port. It's ironic because if they crashed into the iceberg instead of trying to dodge it they would have lived.
Why Boats Sink
Boats sink because when water comes in the ship. It starts getting heavier and it is only a matter of time before everything starts turning off.
In the past pirates loved sinking ships. The reason they it is because they wanted money and treasure. Some might have just did it to feel alive.
