Jake, thanks for the suggestion. Actually, I might have contributed to the breakage. I just switched over from the SS 1x19 bridle wire to using 1/8" Amsteel and the "D" shackle to attach to tang. My thoughts on using the D shackle was once the boat was rigged and the forestay was under load the bridle line/shackle wouldn't move anymore than the stock fork wire fitting. There is no doubt that corrosion played a big part. You can tell from the photo but your thoughts have me thinking.
