I just bought a 1978 25' and I am unclear on how the jib tack gets attached to the front of the boat. There is a fitting there with one hole, I assume for the forestay, and two inverted "hooks"... I imagine that if I attached the jib penant there it could slip off... so how does this all work?The rig was lost overboard before I bought the boat, and I am in the process of re-rigging the entire boat, without, I should add, much experince on sailboats!many thanksKai
