Here's a "new arrival" from Freetime Hobbies that may be of interest to lots of sailing ship fans: http://www.freetimehobbies.com/artwox-planking-spread-sticker-woodsheet-width-2-0mm-for-wood-sailing-ship/ .
The company offers the stuff in several widths, from 2 mm to 3 mm in increments of .2 mm. Looks like it might be just the thing for application to plastic sailing ship decks. (Caveat: I haven't seen it.)
I've always had some reservations about the pressure-sensitive-adhesive-backed wood decks for modern warships that seem to be all over the place at the moment. (Another caveat: I haven't seen any of them "in the flesh" either.) It seems to me that pattern of the wood grain stretching across all the planks on a given deck would spoil the effect. But this new product appears to be made up of individual planks. So one could peel planks from different parts of the sheet and apply them to the model adjacent to each other.
2 mm works out to about 7 1/2 inches on 1/96 scale. A 7 1/2-inch plank is a pretty wide one - though certainly not unheard-of. But for larger-scale kits this might be just the thing.
On a somewhat less happy note, the same manufacturer offers this: http://www.freetimehobbies.com/1-240-artwox-hms-campbeltown-for-revell-3016/ .
Oops. As anybody who's tried to turn that nice old Revell kit into a serious scale model knows all too well, the "planking" detail on its decks is utterly bogus. Flush-decked, four-stacked destroyers did not have wood decks. (In fact, I'm inclined to think the U.S. Navy has never had a destroyer with a wood deck. Can somebody correct me on that point?)
Youth, talent, hard work, and enthusiasm are no match for old age and treachery.
