White Knight "Air Water Space Combat Transport Ship" (Just call it the White Knight)
When you want to move people there are few better options than the White Knight. It has a crew of three and space for ten more passengers + cargo. As the title implies, it is capable of traveling in space air and water, so visits to the Titanic should not be a problem. Due to the fact that there are hostile forces out there, the White Knight is equipped with a massive triple ion cannon, usually scares enemies out of their socks at the sight of it. It also has various other weapons as well.
About this creation
"Gravity must shift in order to change the balance of the universe" (Daniel Bulliner)
I definitely know what you mean by the empty space in the interior. I was thinking that space could be used for small cargo crates, but I never got around to building them. Odds are, I will not fix that (I built this more than a month ago).
You managed to make two?! TWO?!?! *Warning. System overload detected. Restarting software.* Sorry about that... Anyway, the exterior of the ship great! Lots of details to be seen. However, the interior seems a bit too empty considering all of the space you have available inside the vessels.
