Looks to be one of the boats at the site where the EA did the adverse possession claim . Old scouts wharf / Thames water inlets.
Could get interesting.
I don't think it is a hotel boat. Its not one of the slum boats anyway.
Boat name "Pioneers Joy" does not show up on the canalplan boat list which is a database of vessels registered with the various navigation authorities including EA.
It will probably be one of the boats which had been moored there for about 12 years now attempting to make a claim for residential rights.
The story is that the EA did an adverse possession claim followed by boat owners doing veg management and fencing in their "plots".
One would assume that the land will be awarded to the EA and the boats cleared at some point. It's just a matter of when.
And I guess it will be down to the EA to pay for the detritus which will need to be cleared to get the land back as it was previously.
