5 or 10 meter. Makes a difference?

People argue what decks awash is in game, to me it's only diving deep enough, but engines are still running. If you dive deep enough, your electrics will engage and watch crew vanish, yes, you can still roam the bridge, but in all aspects the game views you as dived and you are now a target for sonar. To be it's a cheat to do decks awash when your sub is technically dived.
