International Rules of the Road say the black craft was responsible. They approached the other vessel and cut across the bow from the port side. Port side has a red running lights and rules of the road say if you see approach the side of vessel with red (port side) then you must yield the right of way unless restricted in your ability to maneuver or are a vessel under sail, neither of which apply here. The vessel that caused the collision is responsible for all damages to both vessels.
Picking nits here perhaps, but the schmucks piloting the Ady Gil crossed in front of the Japanese whaling vessel from the *starboard*, not the port side. In any event, pity they and their boat weren't completely crushed and subsequently chewed up by the prop.
