Haaaha. You guys..
My roller furler works flawlessly, due to a lot of attention of setting it up. If the headsail doesn't roll up reletively easily on a broad reach, sumpins not right. Like ill cranking Harleys. They are EASY to crank, if the damn dumb rider knew how to fix his motorbike..
I step masts commonly on the yard that are 65 feet high, and requires a crane. Most if not all of them has roller furlers. And it is a easy walk in the park to do this. I couldn't imagine it being any more difficult on a 22.
And sun covers are easy as hell to put on. Without writing a book, because Don Casey already did on this, that is a home job. Bearing in mind that you are not 'building a sail', just stitching on canvass. If you send that sail off, (to a major sail loft I know in Annapolis that you know as well), it will cost you $11.00 a FOOT! On the leach, and on the foot. To hell with all that. I'm not broke, OR stingy but that'll never happen.
Long straight stitches, use good thread, it'll last a few years depending on how well you do it. Remember they call these "Sacrificial Covers". Do to it as the name implies..
