Martin Lawrence was the editor of the CCC Sailing Directions and left the Editorship to produce his own for Imrays. I thought both different but complimentary in their own way - though I thought - and still think - that CCC SDs are more WCV* friendly in that Martin Lawrence's SDs who tended towards 'here there be dragons', though I'm sure some of you WCES* will poo-poo that idea.
I've never even looked at the Imray directions, let alone used them. I think, though, that the CCC ones were very much dumbed down when they went from the hardback book to the multiple large-format paperbacks, and that may be the same as saying they became more aimed at the virgins.
At the changeover, many of the small anchorages ("Stores:none. Water: at burn.") went oot the windae to be replaced with far more detailed coverage of far fewer places. I get the impression that the level of coverage has been creeping up with successive editions since then.
I'm a grouchy old sod, though, and I really don't like or want a pilot book with aerial photographs and all that guff, for the same reason that I absolutely refuse to use a chartplotter. I like my destinations to be interesting adventures and new discoveries, and for me having photographs ruins the fun. Bah, humbug.
That said, or grumbled, it sounds as if Mr Lawrence made a very kind gesture in suggesting the merger. Well done, that editor.
