Could not get the displacement calcs to conform to anything near reality.
I have a sneaking suspicion that at some time in the past the Docks board (as it was then) pumped about 200 ton of concrete into the lower ballast chambers. Will have to put a man in SCBA to check it out (the air in the caisson is foul).
