If I understand John correctly, the River Hull flows into the Humber at Kingston-Upon-Hull. Correct?
This site (click) seems to confirm that, and gives lots of other information about Hull. This site (click) gives a pictorial river tour.

OK, you Hull people, maybe you can help me in my quest for lighthouses. On the shores of the River Humber, there's a very nice pub that is supposed to be a good spot for singarounds - what's the name of that pub?

In front of the pub is what is reputed to be the Finest Loo in All England, with hanging plants and all manner of decoration.
OK, if I look a long way downstream from that pub, I see something on the north shore of the river that looks like a lighthouse. Is it? If it is, what's the name of the lighthouse?
