Second, I don't see this as a pure Antarctic expedition ship, but also as a patrol vessel for the Southern Ocean.

Well, in my thought that ought to be covered by the "TDS" weight and the "200 tons: Reinforced icebreaker bow" miscellaneous weight (and also the ballast rocking tanks), as she is already intended to be an intermediate-sized icebreaker. Unless you're proposing that I add that strengthening as end belt instead?
