I have yet to hear a convincing argument from you that states otherwise. You need to keep in mind that the Catalina 400 is not your run of the mill deep-v rough water boat.
Clearly your top view shows the Catalina 400 much more full bodied than the First 40 (ignoring for the moment this does not represent waterline area). Such a boat creates more righting moment.
