I'd expect to be able to fill my under-water-boat with water, the very thing it's designed to be submerged in, drain the water, and sail along. If something breaks from that, it's wrong. Shouldn't make a difference if the inside or the outside is exposed to it. Yes, that implies that everything inside the submarine is waterproof, and that things that need to be open to the inside environment must have ways of being drained.
