Meanwhile - the Dinghy Cruising Association journal is held at the printers, for obvious reasons ad so the DCA committee arranged for it to be sent as a PDF. I was really keen to get this edition - part two of my article on cruising the Tamar and Lynher rivers is in it. Nice to see it in print. Too long, too wordy but you have to start somewhere I guess.
