Yep. Back off a bit on your max setting. I did. No more cracks. But I also
slapped a couple layers of biaxial tape over the area. I use a dinghy batten
taped to the backstay. It's marked with strips of green, yellow, red and
finally black tape to mark the tension. Lot easier to see than looking at the
gauge. Gauge reading is really irrelavent to us. We adjust to the sailshape,
look at the tape and then reset it to the tape on the next windward leg if the
breeze is the same.
I've also found the 35-1 likes to "breathe" so we don't use as much backstay
tension as when I first started racing the boat.
The 35-1 has a transverse rib of balsa in that area. Probably more for hard
grounding reinforcement but a bit of strength nontheless.
