To Sink or Not To Sink

I have been in that situation for a couple of times already, it's really frustrating after a long and exhausting approach especially in heavy fog and rain when all you can use is the hydrophone. I myself wouldn't bother to attack such a tiny fishing boat, after all they're just fishermen who wouldn't hurt a fly. On the other hand, that ridiculously low amount of tonnage of a fishing boat isn't worth giving away your presence in the area at all. At least, that's the way I see it.
