I agree. We always go to the Muster Drill, but really, when it comes down to sinking or swimming everything's up to us. The crew are trained to go to their Muster Stations. That's great if the ship is upright and has lights! Otherwise, I think the crew will panic along with the passengers.
For instance, a man on the Costa Concordia was quoted as insisting that the lifeboat's be launched when the crew had no idea what to do.
