Seriously? You are kidding, right?
Which part did you think was funny? Too much work or a before dinner sail? He made sense to me.
Yes, I have laminate sails, no, I have not raced in many years. Lost interest. But I still sail fast and I remember racing.
I've been trying something else out on an old dog of a laminate sail this season. Paint (but not house paint). 99% UV block, no chipping, hasn't worn on the spreaders, very light. In fact, I had samples in the sun for a year first. So far, the only down side I can see is the lack of mechanical protection a heavy Sunbrella cover gives, but that's not really an option, so it is a false comparison. I'm not knocking sleeves, BTW, just adding something to the thread.
I have heard of some disappointments with paint, but the knucklheads used white, which is only about 75% UV block in most brands. In fact, fabric covered airplanes (they use something much like dacron sailcloth) put a UV blocking silver layer under the color coats to insure 100% UV blocking.
I curious to hear of shortcomings, other than Sunbrella is tougher.
