i am replacing my standing rigging on my p16. i have ordered all of the parts to make my own. the stock forestay has 2 parts, an upper and a lower. the two are connected with a shackle. i think it was done this way because there needs to be a place to attach the halyard loop at the intersection of the 2 parts. i noticed that the threads on the shackle are wearing out and i need to replace the shackle. is there a reason that the new forestay i make cannot be a single piece as long as i figure a way to suspend the halyard ring at the appropriate position?
