The empty trawler, the one they've been cutting up for scrap, has been hit by a burst from the big gun on the deck of the Enterprise . It looks as though a big wave picked it up and tried to wrap it around a pillar: one whole side is collapsed in, the bow and the stern are actually bent toward each other. Its back is broken. Its empty holds are ingurgitating a vast, continuous rush of murky brown seawater, sucking in that variegated sewage like a drowning man sucks air. It's heading for the bottom fast.
