I know the starting point was near a series of cranes, then i steamed under a long iron bridge, then turned her to starboard, heading towards a mariner. There was a long jetti before the mariner, with about 6 mooring post. Enabling me to moor up there. That was when she was listing real bad. Even aongside, moored up. Try it out. I was in free sailing mode.
As I said before, I think she's sat on the mud or on the ledge that may protrude from the quayside... Been there, done that with her in a number of quayside locations. You should know the dangers of tieing up too close, being an ancient mariner.
