Jib attachment


New Member
i apologize in advance for not knowing all the terminology, but I am hoping someone can help confirm how the jib attaches to the bow of a 90s vintage Parker 470. The previous owner used a steel s hook, but I don't think that's the best way to go. I can see the jib Cunningham and I can see how that should attach, but the sail does not appear to have an extra hole for the Cunningham, only the one grommet currently occupied by the s hook. Is this right? Should the s hook be replaced by a line of some sort? Also, what is the purpose of a jib Cunningham when you can operate the jib halyard from the cockpit?

Thanks for any help!
