And here's the first negative comment. In real life Decks Awash was useful for attacks, as it lowered the profile. It wasn't useful for cruising as the boat is technically submerged and maintaining the precise depth at any speed above minimum is extremely difficult. The shape of the boat is designed for surface cruising, and anything else will totally destroy fuel economy. If you use Decks Awash for cruising you are taking advantage of the part of the game that is screwed up.
