Cape Town has the Sturrock and Robinson Dry Dock, and Clinton Hattingh was kind enough to send me these images of the latter showing the keel blocks
The Robinson Dry Dock is the oldest operating dry dock of its kind in the world and dates back to 1882. The foundation stone for the dock was laid by Prince Alfred, second son of Queen Victoria.
Now wind forward to August 2015 and to Gloucester where there were two dry docks, and one was occupied by a sailing ship.
I don’t think that caisson has been opened in many years, although in 2017 I revisited Gloucester Harbour and that dock was occupied.
The vessel is the Den Store Bjorn, built n 1902.
Of course there are a number of these drydocks around in the the UK, The most famous one in Southampton is the King George V, and it was the place where the really big liners were overhauled. Many images exist of the dock with one of the Queens in it but sadly the caissons have been demolished and the dock is now used as a wet dock. What a waste!
The first is the dock where the Monitor M33 is on display.
and the drydock where HMS Victory has been for so many years.
Liverpool also had two docks in the Canning Dock area that interested me and both we occupied. The first by the MV Edmund Gardner, a former pilot cutter that was launched in 1953. I was hoping to look around her but she was fenced off and painted in dazzle camouflage.
The other dock was occupied by De Wadden, a three-masted auxiliary schooner built in the Netherlands in 1917.
And finally, there are two more dry docks that I would like to mention, both with preserved vessels in them. The first houses the Cutty Sark in Greenwich.
and the other houses the SS Great Britain in Bristol.
Both of these provide an interesting glimpse at the underside of ships, as well as the opportunity to marvel at their construction and how large they really are.
