The engineroom, for instance, incorporates quite a few of the same items I've seen on the larger models. You need to squat a little to get into it, but personally, I couldn't care less about standing height in an engineroom. My normal posture usually involves trying to service the engines or some hidden pump while blood rushes to my head. This won't be the case on the 45, where the outboard sides of the 800hp MAN diesels are accessible and there is plenty of room forward of them, as well. Thanks to 22 inches between the engines, you can turn around and maneuver easily.
