> Wat? Couple of meters above waterline you need water tight guns?

Water does an incredible amount of damage to deck equipment. Imagine how much volume (and therefore mass) and *force* is in the waves that break over the deck. That's why you often see breakwaters in front of forward mounts -- and even then that might not be enough. Destroyer and light cruiser weapons started being mounted in enclosed turrets (as opposed to open or shielded pedestals) partly to protect them from weather. Fleets actually resisted this trend at first because enclosed turrets are cramped and slow down reload cycles, among other drawbacks. On top of all that, it's salt water, which does a number with corrosion, especially if you've got sensitive electronics
