The diagonal batten is a right pain in the proverbial for the cruising sailor.
Every hoist and stow requires one to climb up and remove attachment so it can be stowed flat in sail bag. In any sort of breeze you need lots of leach loading to keep this sail area working. Try for a little more roach, as you will find there is very little difference in total SA going this route
, or a slightly bigger heady for those light wind
days. Any small shift in CoE will make very little difference to a cat with your underwater profile.
