Wow, I'm so pleasantly overwhelmed with the all these amazing offers of help. Thank you all so much
Unfortunately the plot of my journey has had a slight twist...
I was unaware that on route by lorry from Macclesfield to Watford, the unusual roof mounted fuel tank that provides diesel to the stove inside the boat was, due to the vibrations of the road, spilling diesel through the vents all over the outside of the boat, which in turn has taken off all the black paint on half the boat. So I've now got to hose down, scrap and clean off all the diesel and re black the hull. D'oh!
Note to self and anyone else with this set up: empty or seal the fuel tank before putting it on a lorry!
I'm guessing by the time I've done this work there will probably be far too many stoppages along the route to make it to hackney.
Anyway, despite all this I'm still happier than a pig in sh*t to be the owner of my first Narrowboat, and to discover this awesome community of fellow enthusiasts
