Would a Tiger-derived Admiral improve underwater protection?

Would a Tiger-derived Admiral really be better if underwater protection issues still had to be addressed?

The reply points to Tiger's better freeboard and initial underwater protection, without specifying a complete revised protection scheme.

An evolved Tiger-based Admiral would still need adequate underwater protection. Tiger's higher freeboard and better initial protection supply the argument for her advantages as a starting point. She is treated here as a substantial battlecruiser design. The exchange does not specify a complete revised protection system.
