[Spaceships]Questions

[Figleaf23]

Hello,

I'm just delving into GURPS Spaceships for really the first time, despite having the book for many months. I don't have any of the later supplements yet, so maybe my questions are already answered in them, but here goes:

-How do you handle vessels whose symmetry is not linear (front, center, rear)? What about a craft shaped like a butterfly, let's say, where there are three sections but two basically identical and the orientation of travel is perpendicular to the arrangement of sections?

-What would be the consequence of allowing some sections to be more than 7 slots and others less, provided the basic envelope of total size is maintained?
