I found another video from the same incedent. I suppose this may have happened 2 years ago (if the date they provide is correct). If so, I wonder why it took so long before this video "went viral" and became famous (infamous?).
Anyway, this other video seems to show the CCTV (survelence) video inside the dinning room of the ship. I think this video is even more dramatic/shocking than the previous one. You decide: Rough seas on a cruise: Part 2
