I was invited on board an 80' Norfolk Wherry on the Seine. Although the mast was down, the owner explained that he had sailed it on the Seine, dropping the mast to pass under the bridges. There was an enormous capstan in the focs'le which winched it up again before losing way. And he sailed only with his wife as crew!

Spritsail barges used to do it often. I think they called it shooting bridges. I suppose the Humber keels had to be able to do it but I'm not sure.
There's a couple of photos in Frank Carr's fine book "Sailing Barges showing a barge shooting Rochester bridge.
