It was hopeless by the time they got there -- a total write off in any case. I suppose they were fighting the fire only to try to prevent the boat from sinking, creating an environmental problem. Or maybe to keep down the air pollution.
I think that's also why a lot of the fire hose water was going over the boat -- if they had trained the hoses right on the fire, that water would have sunk the boat.
Anyway, it was hopeless from the beginning. The hull
was already breached, before the fire boat got there.
