I'm really enjoying Hull Zero Three apart from one problem. Lacking the ability to create mental pictures I can't work out from the descriptions what the ship should look like, nor what direction inboard/outboard is, nor what the direction of spin is.

If the following image is an accurate picture are the three hulls spinning around the central spine or are the hulls spinning on the point where they're attached to the spin. Do all three hulls spin in unison or can they spin independently?
