Think of every pirate and seafaring type movie you have ever seen, now pour all that into writing your own great shipwreck scene.
Are you on the ship, or watching from the shore? Do you end up in the sea, holding a piece of the floating debris, do you sink to the bottom or do you wake up and find yourself lying on a sandy beach somewhere? What happens to the ship itself, how does it sink or does it get stranded on a coral reef, some submerged rocks or was it taken over by some pirates? So much drama for the writing!
