The short answer to steve5's question is - yes.
The trick lies in figuring out what "their highest positions" are. A number of fittings stop the yards from being hauled up right under the crosstrees. There's a "swelling" of the lower masts and topmasts a few feet below the tops (in the case of the lower yards) or topmast crosstrees (in the case of the topgallant yards).
The lower yards and spritsail yard don't change positions when the sails are furled.
The topgallant yards and the spritsail topsail yard get hauled up just below the points where the shroud and stay collars are secured.
The lateen mizzen yard gets hoisted up a few feet below the square-rigged crossjack yard (which doesn't have a sail on it). The lateen yard is carried inside the lower shrouds.
I have to disagree, respectfully, with CapnMac on the subject of lifts. The lines he describes are "standing lifts," which came into use in the latter part of the nineteenth century. They were part of the standing rigging. In the seventeenth century the lifts were running gear, running through blocks to be belayed on deck. Quite a few old master paintings from the period show ships with their yards cocked at an angle.
I always recommend that anybody taking on a model like this get hold of a copy of R.C. Anderson's book, The Rigging of Ships In the Days of the Spritsail Topmast. It's an old classic, but just as useful now as it was in the 'twenties. And it's cheap. You can pick up a used paperback copy (try www.bookfinder.com) for practically nothing. I just found one for $5.00, including US shipping. (I'm sure shipping to Australia would cost more, but not too much.)
Hope that helps a little.
