I don't think they would have individually built such complicated harbours for just one location. Maybe they dropped the "harbour blocks" and made some sort of generated harbour that follows the coastline of the given area?
What's frustrating with 0 realism screenshots is that we learn nothing about the 100% realism method of targetting.
