I've got almost all the copies of "The Boatman" + the supplement printed with Classic Boat after they took it over, looking for a good home, otherwise they will go in a skip. I'm missing a few issues: they may be somewhere but haven't surfaced yet!
If you want them you're welcome to them, but you needs collect them from St Albans (or maybe Barton Turf).
(For those who don't know it, The Boatman was Pete Greenfield's publishing venture before "Water Craft" and has much the same flavour. It was bought up by the publishers of Classic Boat, merged into it, and disappeared)
