I need to make a sorta correction to what I wrote earlier about the Unimat. After considerable web searching I learned that an Austrian company still makes two machines called Unimats - the "Unimat I Basic," which is intended for kids, and the "Unimat 1 Classic," which is designed for modelers and other machinists. On the basis of several websites, the "Classic" version deserves to be taken seriously. It can be set up as a wood lathe, metal lathe, drill press, horizontal milling machine, vertical milling machine, and jig saw - all with the parts that come in the box. It's got a lot of plastic in it (one reviewer gave it 2 1/2 stars out of 5), but it looks like, used with care, it could be a good tool for modelers.
Bad news: 1. No table saw conversion. 2. The best American price I could find was over $700.
I don't think the ship in GM's latest post is a fishing vessel. Its bulwarks are too high ( a fisherman had low bulwarks, so the fish in the dory alongside could be forked over them), there are no fish visible (there almost always are in deck shots of fishing schooners), and I've never heard of a fishing schooner with a big deckhouse like that. I think we're looking at a small to mid-sized coasting schooner - maybe something like Bluejacket's Fannie A. Gorham: http://www.bluejacketinc.com/kits/fannie.htm . But for mast hoop details, it's a great shot.
A little care with terminology is in order. A mast band is a permanent, tight-fitting piece of ironwork, usually with one or more eyebolts in it, by which various pieces of rigging are secured to the mast. Bluejacket makes cast britannia mast bands with eyes cast integrally.
A mast hoop is a wood hoop that's used to connect a sail to a mast. Bluejacket's mast hoops are laser-cut from very thin plywood. They're very well done, but there's just no way a piece of plywood can be cut, even by a laser, as thin as a plane shaving or a piece of paper. If I were building a model on a really big scale (say, 1'4"=1'), I'd use Bluejacket hoops. But not for anything smaller.
Now, about boom crutches. Last night I stumbled across a couple of photos of the America relatively early in her career. Here's a link: http://www.sandemanyachtcompany.co.uk/blog/america-an-appreciation . The author of the article, David Matzenik (whom I know nothing about, but he seems quite knowledgeable), says he thinks the shots were made during the Civil War, when the ship was onlyabout 15 years old.
In both shots she's apparently at anchor off Annapolis. In the first shot, all her sails are furled. The main gaff is lying on top of the boom, with the sail between them. The fore gaff is fixed at the lower masthead, and the foresail is furled against the mast and gaff. There's no boom on the foresail.
The second shot is even more interesting. The ship seems to be in the process of getting under weigh.The photo clearly shows the configuration of the sails when they're being unfurled. (Or maybe I've got it backwards; maybe the ship is coming to anchor, and the sails are being furled.)
The author of the article notes astutely that the main sheet is draped over the boom. You can get at least an impression of how long that line is.
That author also makes some interesting remarks on the way her rig got changed over the years.
Boom crutches (sometimes rendered "crotches") were in use by 1851, all right. The Elsie has two - one for each boom. (The Elsie has a hoisting gaff, and therefore a fore boom.) I can't find a trace of a crutch - even one for the main boom - in any contemporary picture of the America. That boom is huge - and, with the sail and gaff on top of it, mighty heavy. The crutch would have to be a really sturdy fixture.
The shots of the currently-sailing replica don't show a boom crutch either. I did, however, find a couple of shots on the web where her fore gaff has been lowered on top of the furled sail. To my eye it looks a little weird.
If I were building a model of the America, I'd probably build her as Mr. Matzenik suggests she looked at the time of The Race: fixed fore gaff, hoisting main gaff, jibboom, and jib club, no fore topmast - or boom crutches. But that's just me - and I don't pretend to be an expert on this subject. To each his/her own.
Here are a few more interesting pix I stumbled across. The first one shows her being towed out of Boston Harbor by a Navy subchaser in about 1930: https://www.digitalcommonwealth.org/search/commonwealth:3t946q72v .The second apparently right after she got to ... well, wherever she was going: https://www.digitalcommonwealth.org/search/commonwealth:3t946q74d . Lots of deck details are visible, including the beautiful skylight that's now at the Mariners' Museum. But no crutches.
