I don't have holes in my bows I have dyneema line running from my bridal tangs to the end of the pole and another dyneema line running from the bridal tang straight across the boat to the other tang attaching to the pole in the middle. Just do the two shackles up at the bridal tangs then tighten the line under the jib bridal until your happy with the bend.
