My impression on the short moment where the whaler ship steered toward the Ady Gil, was that it was a last ditch effort to break the intercept path by steering toward the opposite direction the Ady Gil was traveling, in hopes of skating by the other side of the craft. Unfortunately, there was just not enough clearance for this to be useful. The Ady Gil had left themselves in a spot where it would not have made much difference if the whaler ship turned left, right, or just went straight. There was going to be some sort of inevitable contact.
Margot Robbie is THE most exquisite human creature on the face of the planet, in this moment in time.
