I looked into supplies used by larger ships, and don't see a way to do it except by engines (I don't think anything else can be made to use supplies per movement - if someone knows differently, please let me know).

So, to make larger ships more range-limited, all I can think of at present (since larger ships generally have _more_ spare space for supply storage), would be to jack up their engines/move rating, and then provide two sorts of engines - high-output engines with high standard thrust but high supply consumption, and long-haul engines with lower thrust but lower supply consumption. In this way, a large ship could be either very slow and long-range, or reasonable-speed but short-range (or jammed full of supply storage). The side-effect would be that you could put high-output engines on a small ship and get a very fast short-range interceptor. Which might be a neat system overall - I'll play with making Proportions more this way, and see what I can come up with. I think I won't make it as extrme as dogscoff mentioned, because Proportions ships are already pretty short-ranged unless they stock lots of supplies, and I think just having large ships be significantly slower already limits them pretty well.
