To try to cut to the chase and stop unnecessary chasing of rainbows, do you have an approximate idea of budget and what part of the UK system are you thinking of? Are you a newcomer to the waterways or do you have any prior knowledge of what is involved in owning and maintaining a boat on the waterways? As you can imagine this site gets a number of such requests and peoples ideas of what is available and for what price varies enormously. It is always helpful if you could give an indication of what you hope to get out of boat ownership, i.e. extended cruising, weekending, living on board permanently etc.
