I just finished reading an excellent canal book called "Journey into England"---Can"t remember the author, sorry ! Anyway,there were a couple of references to ghosts---One ,a headless woman who shrieks at boaters as they enter a tunnel ( Blisworth ??) and also a haunted stretch of canal cutting where the old-time boatmen & their families were too terrified to moor for the night !! Sometime in the last 2 or 3 years, I read,either in "Waterways World" or "Canal Boat" ,an article about a live-aboard couple,where the wife is ,in fact, a professional medium specialising in inland waterways ghosts !!! --if you contact either of those magazines,they would probably let you have the article---it"s fascinating !!
