A Question to Scott Kelloggs Designs

Hello out there,

I have some trouble with Scott Kelloggs designs. In part 7.3 of his
submissions, he describes the Battleship BISMARK and in part 6 he
describes a Boeing 747. I wonder, why both have a displacement of 6000.
Can somebody tell me, why so different vehicles have the same displacement ?
