They are much kinder to a laminate sail...
Speaking of Leisure-Furl, the other day on Delaware Bay, I saw a freakin' BRISTOL CHANNEL CUTTER sporting a L-F boom! I think it is finally safe to say, I have now seen EVERYTHING... (grin)
Yeah, I'm getting to the same point with my 3DL main, as well... I won't be buying such a sail again, as much as I have loved it, next time it will be a straight dacron sail, for me...
Your boat still sure looks great in all those North Sails ads, Bruce... what a beauty...
