Those strange vessels reminded me of a photo from Rivoldini Ron I showed on TEESSHIPS back in 2004:
I posed the question: Ron's title of "floating kettle" seems apt but he can tell me nothing about this strange craft. So, who can, please?
And, yes, relevant info did arrive, as follows:
Ron! the floating kettle, the photograph is taken on the River Tyne approx - wait for it! - on the 15th Sept. 1960. I say approx that date because I have a photograph of the same vessel with that date on the reverse. It is the vessel alright - it's even got the same two fellows onboard! So I said the date was approx but I bet it's not far away. It's even got the same two pumps in the hold. As to the name it's the "Ill try" {or should that be I'll Try? - Ron}
it's a clinker built Tyne Wherry Oak planking on oak joggled frames with a counter stern and was built in 1863. It has what was known as a haystack boiler. There were a number of these screw wherries as they were known on the Tyne as well as the more numerous dumb wherries, the Elswick No 2 being the last one, it's now in the Beamish museum ( not on display) Other screw wherries were Kimberley 1900, one of Cookson's. Thomas & Alice, Sovereign, and the Alice.
The boat was a "water boat" taking fresh water to the ships in the river Tyne.
I hope this is a help. regards Richard Walton. This "floating kettle" was thereby still in service approaching 100 years of age. While not identical to those in Kevin's photo they all seem fairly similar in concept.
Who can tell us more??
Ron
