If you've achieved escape velocity from the 2nd body (eg, Earth) but not the first body (eg, the Sun) you can keep swinging around the 1st body stealing speed off of the 2nd one each time. Takes some careful orbits and a long time, but NASA does it all the time.

- hinkley 7y agoIf you have the energy to get to black holes rotating around each other, you probably can build ships that don't need to slingshot. 'Cept perhaps for braking maneuvers.
