Living on a ship at sea, or underground / underwater, should give enough protection against whatever post-apocalyptic situation exists on Earth, it's pretty much always going to be more survivable than Mars or outer space. You might need a protective suit, air filters etc. Still 100x easier than having no atmosphere at all.

If they can reach your submarine, they can reach your space colony.

		Surprise Dodgeball reference. But I don't think the ocean is as far away as deep space. I also think due to its proximity, it could be entangled in political paradigms that lead to entanglements in international conflicts and the independence from those political paradigms affords a form of insulation.
