Was that major refinement to the DungStain ship or refinement to your MOC? You could possibly "refine" the DungStain ship into a pirate ship!
Oh, sorry that I wasn't clear, I did a refinement on my ship (Now that I took Joe off I don't have a name :-| ) I despise the design of that HP ship even though it has good pieces. It is WAY to high for it's length and I think I can't change that since middle hull pieces that match these don't exist yet (I think). But if you really, really want I can make a horrendously out of proportion pirate ship that wont be as good as mine.
