Twenty odd years ago, a small cruiser was served with notices and eventually dragged off the towpath mooring it was on, where it stayed for a few weeks. A 'perspective buyer', (tea leaf?), had a look inside one day and found thousands of dead flies and the remains of its unfortunate owner, a loner, who had worked on the nearby trading estate.
Obviously no one had told the section 8 yard at Hanwell about this policy, there was a merry go round of semi derelict craft seized and taken there, only to be bought cheaply by the occupiers of the Toll House at Cowley, and returned to within spitting distance of whence they were seized!
