The collision at the very end, involving the Steve Irwin is another related incident showing the bow of the Irwin ramming a Japanese ship. Note that, according to the voice over, the eco-terrorists deny that the collision in that clip (the end) ever occurred!
The first part of the tape appears to be the collision referred to by the title - where the stern of the Japanese ship hits the side of the other.
Video seemed to be of Steve Irwin ship turning and hitting a ship marked Research ship.
I’m not sure if that video was supposed to be the incident under discussion.
