An example is if I do the out of the main book and just decide you are getting 70 SP. I think the repulsive costs like what, 70 points. So now you have nothing really aside from the hull and basic stuff to make the thing go vroom vroom. If I take the expansion warrant of trade path thingie, I think you max out at like 68 or 69 points, which is just shy of the whole GC idea. When I go through character paths I see a few instances of +1 profit, but nothing that says +1 SP.
IIRC, the Warrant path can get you 72 ship points at most - I might be wrong.
The Dynasty "homeworld" (in Into the Storm) gives you +3 extra Ship Point per character taking it.
