The video does show the crew of the Andy Gil to be reckless idiots though.
That part you got right, because they appear to be kicking back basking in the after glow of a fun and productive day harassing the whalers, not reacting soon enough to the obvious aggressive and eventually illegal attack by the significantly larger "Research" vessel.
While the last "lurch" starboard by the whale murderers may have been due the swell, the Captain put his ship in a position where he could not keep from running into the Ady Gil. In a panic, the fact that AG throttled the wrong way does not make the SS crew the criminals in this incident.
Say all the bad things you want about Captain Paul Watson and his tactics but it would seem the Whalers have finally played into his hands and shown who is actually endangering human lives over the "right" to kill whales.
