Stratford-upon-Avon boats

We spent some time in Stratford-upon-Avon, of course I knew of it because of Shakespeare, but I was surprised at how many long/narrow boats (which ever you call them, not sure of the difference) there are, trouble is you can't stop yourself from wanting to have a quick neb through the windows as you walk past! Trouble is it's now set him off wanting to live on a boat again, all very well in the summer I suppose, apart from the lack of garden, but in the winter!!
