Rodney versus Iowa in a stormy Atlantic

How would HMS Rodney fare against an Iowa-class battleship in a stormy Atlantic?

With Rodney's Bismarck-era captain, Rodney is favoured; under other command the fight looks much more even and possibly mutually destructive.

Command and environment are central to this hypothetical rather than specifications alone. In a stormy Atlantic, Rodney is favoured if she retains the captain who handled her against Bismarck. Without that leadership advantage, the expected result is closer to mutual destruction. Seakeeping, tactical judgment, and willingness to close can matter as much as nominal speed or gun statistics in a battleship duel.
