10 percent lightspeed is the limit

Above 0.1 cee, interstellar protons impacting the ship hull will have sufficient energy to flood the ship interior with gamma rays, killing everything inside. Not instantly of course, but long before reaching the destination.

Below 0.1 cee, you'd never get there.
