Hello again, Chris - there are several different mags - one possibly called Narrow Boat or something similar. I would suggest getting someone in your local WH Smiths to look up on their computer index of mags, you should find quite a few. Or - have a look in a newsagents situated by a canal marina, where they are likely to stock such mags (that's how I came across them - our Spar shop gets them in cos we're by the canal).
