Hi jobhboy,
The following is taken from Hull docklands, An Illustrated History of the Port of Hull.
Princes Dock 1829-1968
"Powers were granted in 1802 for the construction of a junction dock, between the two older docks (Queens and Humber). But only after pressure from the forerunners of the present Chamber of Commerce and Shipping was work started on the second part of the project.
Mr John Parker, Chairman of the Hull Dock Company, laid the foundation stone on the 10th December, 1827. The Junction Dock was constructed at a cost of £187,262 6s 5d at the sole expense of the HDC. It was opened to traffic on the 1st June 1829 and completed a line of docks connecting the River Hull with the River Humber, along the site of th old wall, the military fortifications formerly protecting the ancient city.
The Junction Dock was renamed Princes Dock in homour of the Prince Consort's visit in 1854.
Princes Dock was used for vessels trading to the following ports: Bremen, Dundee, Hamburg, Rotterdam, Rouen, Bordeaux, London, Leith, Grangemouth, Aberdeen, Ipswich and Lyon.
The dock closed to shipping in 1968."
The dock has been given a new lease of live as the entrance to Humer Dock has been blocked and a shopping centre built on stilts over the dock which is now called Princes Quay.
There are a few pictures on Princes Dock (one of 1900) and the dock is filled with barges.
btw, is Princes Dock on any of the maps I sent you? If not I'll send you a copy.
