Something else just occurred to me . . . is it a scupper ball valve? A drainage valve that only works in one direction (we have something like this on our heating system). . . The ball is now missing - but it allows bilge water to escape from a hull without allowing sea water back in. The hinge bolts are there to allow it be opened occasionally so the ball can be cleaned (bilge water would be full of oil and occasional chunks of decaying rat - so ya gotta keeps da ball clean or it won't work.) Normally this kind of thing would have to be above the water line, if it was below sea level it wouldn't work.

I can't find anything that looks quite like it on the web but ebay has a whole variety of them - brass ones available too.
