Hi Dave
Thanks for the extra advice, no your boat was not too narrow at all (it's really what I want) . I'm still throwing it all about and as it's a retirement project I thought why not do it in France too, where it's a bit warmer in winter. I agree with your point about going over the top and the extra expense just to cross the channel maybe once or twice. (and lose out here too). I'm back to the narrowboat and transporting it by road, looks like the cheapest and best option. If they are not ideal for all canals in France, I'll just be more selective over there. I also take the point of not being able to transit North to South easily.
Daft question: When say transiting a busy canal with commercial traffic in France. Could you fit a stabiliser of some kind??
Don't worry, I'll invite you over for a tour!
