yeah... the Sea Sheppards captain via interview claimed that the Whaling ship changed course to hit it while it was "dead in the water".
yeah right.. you can see it "power up" from the cavitation bubbles from the outdrives and run it into the stern of the whaling ship.
Looks to me that they tried to take a easily breakable boat without watertight compartments (either that or they weren't smart enough to close the hatches) and try to ram a bigger object. Because of that, they flooded all compartments of their new toy boat. their stupidity .... it's almost entertaining....
