I think most folks have missed the word NARROWBOAT in this post... Living on the cannals of England is a lot less trying than many living aboard problems. I have been toying witht he idea myself, though the Mrs. says, Nope, so nope it likely will remain. There is a very good complete little narrowboat marina just outside Devises, called, remarkably enough, the Devizes marina. I believe the fellow to speak to there is Richard. Drop me an email at InOBU@aol.com and I will search up his number for you. Also there are some narrowboat folks at Foxhangers in Wiltshire who can assist you. You have my best hopes and wishes. Of course the only major difference between a boat and a house is that both the roof and floor leak...
