Not really. They wouldn't design special cargo containers for just one ship class. They would use the standard DY series cargo containers, the ones that were designed to go around the cylindrical hull of the DY's. This hull design simply doesn't permit such a placement with said containers. So, they loose some theoretical cargo capacity, but they can charge a premium for shipping because of it's reduced transit time, which offsets the smaller total amount of cargo shipped. Sounds perfectly logical from a business standpoint.
Perhaps it's simply "form over function"...it looks good? (I'm not criticizing your question, as it made me think about it) I know I do things like that all the time, (in my case) bizarre shapes that have no correlation to any real-world engineering, but "look cool"...or at least try to Maybe these could be specialized containers, for a specific customer, 2 part or multi-part containers that have rounded areas for fluid/pressurized containment, as well as dry/non-pressurized areas? With big square boxes, I keep picturing the old kit-bashed BSG "cargo hauler" ships... About Kerkythea, Good Mercy! Is the stuff on their site representative of what you could render from sketchup meshes? That's amazing.
Made a subtle change to the shape of the hammerhead. It was just a little too square in the overhead view for my liking. You can also see I am working on ideas for alternate cargo pods.
Looks great. Can't wait to see the finished version. That blank spot on top of the tower would be a good spot for a docking adapter.
Yea, I actually left it blank in possible anticipation of putting an airlock there, though it would intrude on the cargo control room, so if an airlock does get put in, it will have to be moved forward and those greebles re-arranged. Couple more small details to end the night:
Mixing the Dy lineage with the XCV-330 ringship type drive is great stuff. The DY-700 could easily be a contemporary of the "SS Enterprise". I'm liking this big time.
