Here’s a video of the collision and it shows the damage to the bow.

Okay. I just watched that video a few times, with the sound off. Looks to me the little black boat rammed itself into the “really really big ship”.
Also looks like the ship was trying to ward them off with some kind of large water hose. They refused to stop their ramming into the big ship and got hurt.
