Man, those things don't float...
We lost several on our first big trip out. When the first one hit the water I heard it, (sounded like I bullet going by) but it didn't even make a splash. I saw the second one working it's way out while we were luffing, but couldn't get the sail down in time to save it. Our first fix was simply replacing/ upgrading the Doyle velcro, which slowed the departure rate some, but was ultimately not the best solution. After Elvis left the building again, repeatedly, we just removed the velcro altogether and sewed the battons in place. The only disadvantage is you can't fold the sail lengthwise. You can buy batton material and caps from WM and cut to length. As I recall, it was quite inexpensive and they shipped almost immediately. We also considered installing a metal snap in the velcro closures, but concluded it wasn't worth the bother. I'm no engineer, but the battons do seem to me to help the sail shape in light air.
