I'm all about "pack as much crap as safely possible into bare-minimum space", so I vot "Standing Option 1"--if the walls between compartments are thick enough, it might be possible to stick labels on top of 'em to keep track of what's where.

Next question: do reflags get slots by sculpt or by country? (For example, does HMS Impetueux go with the other Temeraires, or the other Royal Navy SOL's?)
