on the first sail pic...more tension on the bottom batten...

Cheers, I usually get the batten tension, close and adjust again after a sail or two, to let it bed in and stretch, etc.
Ive been running 17 blades that have a fantastic range, and stable power, super strong construction.
Ive been loving my 5.6 S-1 as my light wind DTL wave sail, super light and crisp to wave sail with, de powers when you want it to, not the wind range of the blades, and needs careful setting of the outhaul and downhaul, but comes alive when you get it spot on !
Looking forward to some epic wave days with my 96L CA Kina and the S-1's !!
