Jerry, the 192 came stock with the Schaefer furler for the 110% jib. The drum mounts to the U bolt mounted through the deck just behind the stemhead fitting. Then, the jib halyard hoists the jib with the swivel at the top. This is why they have a winch mounted on the port side of the mast - it's an attempt to get the jib luff somewhat tight.
I had heard that most Scheafer furlers broke at some point, or didn't work too well to begin with. I sailed with mine for about a month after I bought the boat, but I didn't care for it, because my halyards were tired polyester double braid, I could never get it tight, and the jib was original, so was pretty blown out. Since my boat came with a newer hank-on jib, that's what I've been using instead. After I replaced the running rigging with Vectran cored 1/4" (total overkill, but more money than brains…), sure, I probably
could have got that luff tighter, but now I'm using that hank on exclusively, and I have a downhaul rigged and a deck bag, so it's not a horrible setup. This year, I took off the winch so that I could make room to put on a swiveling cam cleat for the asym spinnaker halyard. Makes for easier takedowns than the horn cleat mounted above the gooseneck…
If I ever go furling again, it will be a Scheafer Snapfurl with a 135% genoa with foam luff, reef point reinforcements in leech and foot, and Sunbrealla strips. Gosh, that setup adds up quickly $$$, and then I'd have to figure out where in the world to mount jib track. One guy I know has it down his side decks (ick) and another has it along the edge of the cabin top, so that it looks like an eyebrow over the windows. Not sure if it's long enough in that position.
Have been considering removing the fixed jib sheet fairlead block in the middle of the cabin top, and replacing with a 12" strip of jib track, so that I can control jib twist and power better, but for right now, she sails ok and I'm tired of fix up projects



Any jib track would involve "potting" the deck with epoxy to protect the core. Just another time consuming and annoying job. Might be easier to consider if I had a garage to work on the boat in the off season...
Oh, shoot, there was a very nice writeup of the 192 in Small Craft Advisor a couple years ago. I should scan that for you… It's where I got my avatar picture...
