A simple job, really, easily accomplished:
- Sand the batten.
- Cut the TOWs to size.
- Laminate one layer of 1" wide by 11 oz. graphite to each side. Taper fibers to avoid a hard spot. I did this by ending the fibers about 6" differently on opposing sides.
- Sand lightly and add a second coat of epoxy.
- Sand lightly again, by hand, 220 grit or finer, to get any sharp spots.
- Epoxy again. Optional; I didn't.
I am still going to re-cut the sail. I believe I need to remove ~ 3/16" out of 2 seams, 50-70% of the way up. The "after" photo shows some residual sag. But the stiffer battens were a huge help on the sag and treated some vertical wrinkles as well. I will be happy until fall.
