Well, I don't like the fat narrowboat ones, I think they are a result of lazy boat design, or in fact not much design at all. Most narrowboats are (loosely) based on an existing historic design, there is not much history of wide boats on English canals to design a half decent `Replica` from so what you end up with is a boxy thing with all the grace of a brick built with little shape and as cheaply as possible. People will say that it would cost far too much to build some shape into them, OK, it would cost more but decent side decks for ease of use and safety and better ends is not hard to do. Just to say, my own boat is `Wide` and a damned hard thing it was to fit out because it is all curves but somewhere between the two extremes it should be possible to do it better. Now where`s my pencil and a sheet of paper,
