A couple of threads involving the Cutty Sark are active at the moment. Whenever this subject comes up, I can't resist calling attention to what I regard as one of the best (and certainly one of the cheapest) sources of information about her: the set of three plans by George Campbell. I think it's appropriate to mention them now, because the process for buying them seems to have changed recently.
The plans used to be available via mail order through the ship's website. That site appears to be gone from the web now. It seems the Cutty Sark has, at least for some purposes, been amalgamated with the National Maritime Museum, Queen's House, and the Royal Observatory into one organization called Royal Museums Greenwich. Part, at least, of what used to be the ship's own website is now included in a sort of super-website: http://www.rmg.co.uk/ . Click on "Cutty Sark," then on the big picture of the ship. That takes you to her portion of the website. When you get there, click on "Shop." Then type "plans" into the "Search Shop" box in the upper right. Here's the link that will take you to them directly: http://shop.rmg.co.uk/search.html?SearchTerm=plans .
As you can see, the three sheets cost 4 pounds (that's $6 or $7) each. I don't know what the shipping charges would be, but when I ordered a set a few years ago they were quite reasonable.
I bought my first set on board the ship many years ago, and literally wore them out. That old set was printed with the "blueline" system (blue lines on white paper); the ones available now are printed in black ink on (pretty cheap) white paper. They aren't quite as sharp as the old ones, but they're plenty good enough for modeling purposes.
Mr. Campbell was the naval architect in charge of the ship's restoration back in the late '50s and early '60s; he knew whereof he spoke. Those drawings contain just about every conceivable detail of the ship, from the hull lines to the sizes of the rigging lines to the sails to the pattern of the linoleum in the galley. (They also make pretty conspicuous the errors and simplifications of the Revell kit. It's a fine kit - especially by 1959 standards - but it does offer the modeler lots of opportunities to improve it.) The voluminous notes all over the sheets make for quite a bit of good bedside reading. Highly recommended to anybody tackling a model of the ship.
I googled "Cutty Sark plans," and was led to another rather interesting web page: https://www.google.com/search?q=Cutty+Sark+plans&hl=en&client=firefox-a&hs=zmJ&tbo=u&rls=org.mozilla:en-US:official&tbm=isch&source=univ&sa=X&ei=KlnsUIqwE8eW2QXV_4DQDQ&ved=0CDIQsAQ&biw=1024&bih=605 . All three of the Campbell sheets are there (if your printer is of sufficiently large format you might be able to print them out at a usable scale), as are several pages from the original Revell instructions - along with lots of other drawings, photos of the ship, photos of models, etc., etc. (How those other ships, and airplanes, got there I have no idea. For that matter, I have no idea who put the page together.)
She is, of course, a great subject for a model. The Revell kit has a lot to recommend it. My favorite plastic version of her, though, is still the long-unavailable 1/125 one from Imai. (I've commented on it - and its rather amusing inaccuracies, at least one of which looks like it stemmed from the Japanese designers' not being able to read Mr. Campbell's notes - several times before here in the Forum. A Forum search on "Imai Cutty Sark" should bring them up.)
Fascinating and rewarding stuff.
