Random question that I need ideas on.

What would be a good way to give demise to a ship and those who are on it?

I know of an Ice Burg that was what sank the Titanic which is sad but fascinating. Many ships do sink by them and depending on how bad it is depends on how long it takes to sink and where it got cut at.

I also know of rouge waves which are really awesome! Yes they are common and are deadly to ships of all kinds. Many ships have capsized because of them, the Queen Mary almost capsized but didn't. That inspired books and movies and it is unpredictable.

Those are two ideas I have for a way a ship is gonna do down and by ship i lean luxury ocean liner *coughs* like the Titanic *coughs*.

A this us merely an idea for a future book I have in mind. So if you have any other ideas shoot. And no, i am not meaning megalodon, those sharks are extinct and thank goodness that they are they are freaking scary. But it could easily take a chunk out of the ship and sink it, meaning no one is safe even survivors. Ooh.

Just please give me some ideas guys, thanks!
