Mike, I agree with you completely - and I've got quite a list of sailing vessels I'd like to see kitted in large scales. (American clipper, American whaler, seventeenth-century English warship, any American frigate other than the Constitution, etc., etc.) But I'm afraid the chances of getting our wishes fulfilled are slim to none. If I'm not mistaken, the Heller Victory was the last large-scale (and large-sized) plastic sailing ship to come on the market - and it was initially released more than thirty years ago. Heller hasn't released a genuinely new sailing ship since. Revell USA has been out of the sailing ship business for about forty years (about twice as long as it was ever in it). Revell and Heller, remember, are the only companies that have ever produced three-foot-long sailing ships. And they only made a handful: the Revell Cutty Sark, Kearsarge, and Constitution, and the Heller Soleil Royal, La Reale, and Victory. All the other big Revell kits (Thermopylae, Pedro Nunes, Alabama, and United States) are modified reissues. (I'm not counting that "Spanish Galleon," which isn't a scale model of anything.) I think Imai may have made one or two that approached that size, but Imai's been out of business for well over thirty years.
Revell Germany has released a few smaller sailing ships since Revell USA got out of the game (the Pamir and Wasa, for instance), but those have been few, far between, and, apparently not exactly big sellers. Trumpeter, apart from a couple that, as I understand it, were reissues of kits from some other Chinese company, has never made a sailing ship kit. Zvezda made a couple a few years ago, but seems to have dropped out of the market.
I'm afraid the plastic sailing ship market is just about dead. Anybody who wants to get into the sailing ship model hobby needs to look carefully at switching over to wood. The number of good wood kits isn't exactly overwhelming either, but there are enough out there to keep people like you and me busy for the rest of our lives.
Youth, talent, hard work, and enthusiasm are no match for old age and treachery.
