To some extent this is true, volume as such will remain same, interior volume will remain same, but the cargo space becomes more organized with 2, no doubt, no doubt about it. But definitely the shoulder effects matter, this also the same thing.
For the same reason the LCB plays an important part in resistance. Longitudinal centre of buoyancy- it indicates how much volume is in the forward and how much volume in the aft, is it not? So, if in my design, if the forward portion is giving me a major effect of resistance, then I should adjust my LCB accordingly, maybe I require to move the LCB aft, so my aft becomes full and forward becomes finer may be. But that is not always the case, this is the case generally for fast ships, fast fine ships that I move my LCB aft so that my forward portion is finer, but in full form ships just the reverse occurs, I may have large amount of separation coming up in the aft, so I may like to refine my aft more than my forward where wave making is not a major component, I may like to shift my LCB forward. So, as the block coefficient goes up the LCB starts moving from aft to forward, this is general, I am only talking to you how the parameters get affected due to resistance, I am not saying these are guidelines strictly, you can have a different design with different LCBs, test it and find that it is better- am I clear?
Now, you see, this sectional area curve is so much related to how much area I give in the middle- is it not?
