OK, not about the landing crafts themselves, but the ships that carry them. What are they called? LST's? Anyway, I was watching the movie "The Longest Day" and it showed the part where they are deploying the landing craft out of the big ship and the front of the big ship is open to allow the landing crafts to depart.

Maybe a silly question, but how does the big ship not sink? Here is the clip from the movie

Eureka!

It's all about displacement! As long as there were enough watertight areas below the waterline displacing an equal weight of water, that equals the weight of the ship, then she stays afloat. I imagine the keel/bilge and side areas accommodated the necessary voids.
