How do sunken ships like the titanic not get crushed under the pressure?

Question

I assume the metal and materials the boats are made of are strong but surely not to withstand the pressure of being 12,000 feet underwater? At the end of the day it’s not like the engineers had to consider holding up to that much pressure in their design right?

Answer 1

Probably already got your answer, but if you want to see it in action, fill a balloon or a plastic bag with air and put it under water in your bathtub for example. That’s the submarine. Now fill it with water and do the same. That’s the ship. You will see the difference yourself.
