My licence is like road tax and covers all canals and navigable rivers unless they are privately owned in a narrow boat you can cover over 2000 miles of waterways, but mine is a bit big and limited to about half of that though I can go to sea in it and nip around the coast if I really needed to, the canal network is like the original motorway so you can travel around most of it without getting out of the water, if I want to go to Bristol, London etc I have to go down here the Severn estuary though I,m not in any rush to do that, nice to look at but a bit of a bum twitcher in a flat bottom boat
