I just finished 3 Patrols with a Sboat for the first time (I usually started late war)
Makes you fully appreciate the tactical freedom of stern tubes, being able to get past 13 Knots and having a boat with a bit of mileage.
And I'm only in a Porpoise class =p
On Topic: The dive times on it are crazy, but notice that once the decks wash over it sinks like a stone. If you compare it to a fleet boat, which have a fairly steady rate of descent, the Sboat's delay before going down makes it seem like a eternity. Just order crash dive and hold on
