Unlike the Skookukway Carrier and the Sky Reach, the Whaleship evades being drawn as my mind's eye sees it. Probably calling it a Whaleship is a bad idea, since it limits the shapes I can use.
The Whaleship is a gigantic airship. The buoyancy lifters are the huge bags on the flanks of the ship. The livable area is the size of a skyscraper building turned on its side. Skooks and Sky Reaches can access the cargo via the underslung dockyard. I drew one of each for scale.
This version is the intermediate between my two other ideas. This one is whale-shaped, so it's got a nice organic visual appeal. The more obvious idea is to take two zeppelins and duct-tape a sideways skyscraper in between them: that's been done before, but it might be a more feasible design. The other idea is to make the buoyancy lifters be more like sails or wings so that the Whaleship looks more like a massive butterfly or moth. The slender body would be dwarfed by the lifters, giving the craft unlimited buoyancy.
