earlier this summer I managed to spit a batten out at some point during a day sail. Yesterday we had some pretty good wind (18-20kts), and after a few hours out playing around I looked up and noticed that same batten had jumped overboard again. I'm trying to figure out how I managed to screw up sliding a batten into the pocket. These are not full length, in fact that one is only about 24" or so. Should I be sewing them in place? I slide the batten in, push against the elastic enough to get the aft end in, then tuck it into a little pocket. Seems simple, but after losing two now I must be doing it wrong. Any help or advice? Also, what's a good place to get more?
