Have you ever been on a carrier? I have only served on the RN CVS and getting around one of those 'baby carriers' is hard enough, without adding the extra hulls to get lost on
! Also I would imagine the cost would be prohibitive - I think it would be cheaper to build one hull instead of two or three.
Mind you, you could keep all the fishheads in one hull and the wafus in the other............................
