What is the maximum speed possible without hyperdrive?

This question:

How do you go from Naboo to Tatooine without the hyperdrive?

seems to be making an assumption about the speed of travel for mainstream craft in the Star Wars universe without using hyperdrive.

What exactly is the maximum speed without hyperdrive in canon?

Is it possible to get arbitrarily close to the speed of light?

This should be in canon, and not using some loophole alternative to hyperdrive which is still FTL.

• This isn't a fair question if you exclude the loophole alternatives, because you assume that FTL travel is impossible.

• @Richard: It doesn't matter to this question. I'm just giving the context of why I'm asking the question. It doesn't matter if the premise of the linked question was wrong. Jan 7, 2016 at 17:55
• I think we can definitively state that the majority of small craft can do, at most, 12 parsecs per Kessel Jan 7, 2016 at 18:08
• Time and distance in SW universe are completely inconsistent, it's all set up in a fairytale-like fashion, to avoid all the waiting. Basically, you can get everywhere before the audience gets bored. Also, communication transmission appears to be instantaneous. Jan 7, 2016 at 20:55

I think there is no speed limit. In space there is no really drag force so the ship is inertial. The FTL drive is use as an big accelerator to get to the speed of light fastly. Because using ION engine it will take too much time.

• Apparently, you are unfamiliar with Einstein's Special Theory of Relativity, which states (briefly) that nothing with a non-zero rest mass can be accelerated to the speed of light. Jul 28, 2016 at 0:27

• @Spencer, yes. You're right. But in just about every variation of Sci-Fi the restriction on FTL travel is recognized, thus the necessity of things like hyperdrive, warp drive, etc. I can think of no Sci-Fi that gets to FTL travel just by applying more and more thrust. Yeah, sometimes the physics of getting there is still...hokey...but... Jul 28, 2016 at 18:53
