There's no such thing as "accidentally" sinking a ship.

You should be able to craft Z1 if you use Bismarck, I-8, Prinz Eugen or Z3 (and probably Z1, but that's not really an option for you) as your Flagship, assuming you did the Quest for her. I don't think crafting is possible without clearing the Quest first (that probably doesn't apply to many people).
