Hello to all you big and little boat people I have a house that wont go anywhere and my own pavement(yes its a terraced house) and at sometime in the future I would like to sell up and move to a boat,but I dont know which I would choose.I like the big wide beam boats for the space but I like the narrow boats as they can go anywhere and having read all your comments Im still no nearer a decision. Can someone please invent a narrow boat that you can inflate to a wide beam when your not cruising around
