There's abundant precedent of accelerating to high speeds in space, where there's no friction with an atmosphere that slows you down and where you can use gravitational fields as sling shots.
0.3c might seem high but if you keep accelerating you will eventually reach that speed.
The ISS (1998) travels at 17,400 mph.
