I just broke a side stay shackle last weekend racing, while in the lead, I might add. Finally got ahead of Leah and Dave.
My fault, however. I sailed Mary's boat and when I got to the club there were no sidestay adjusters or shackles, so I dug around in my box of goodies and found a couple that "might do!"
They didn't do.
So, I went to my very own store and ordered a bunch of Wichard Shackles (best on the market) so I am good to go now.
