Both the whalers and the protesters blame each other for the crash..."In the last few seconds we realised, they're actually going to collide with us..." I wonder which boat was more maneuverable - the smaller faster boat?
If you play chicken with a whaler, you're the fool to expect them to flinch.
What the fools do is race up to the whaling ship and then cut across the ship's bow in an attempt to deploy a homemade 'Prop Fouler'.
I haven't see the video, but I'll a get this is what they were trying to do.
