both ships have responsibility to ensure there is no collision.

a general rule of thumb on all water ways is that "working" vessels have priority of "lesuire" vessles.

however that is not a right to take no action or ram.

example:

a sailing boat and cargo ship are on collision course.

the cargo ship will hold its course as it has priority (right of way) over the lesuire craft.

however if it becomes clear that a collision is likely then the cargo vessel must take action to avoid the impact.

another point, the maru has bow thrusters, these were not engaged, were the captain of the maru doing everything to avoid a collision then they would be at full thrust.

what it comes down to is that the gil was obviosly "provoking" the whalling ship, the maru stepped in.
and got pissed off and thought to hell with it, lets take out the tiny boat.

its not the crime of the century, and if they were flitting around the bigger ships with water cannons being fired at them, they clearly knew they were taking a risk.

I doubt they were expecting the maru to ram them (which it did) but thats really neither here nor there when your in international waters
