headstay tension

Hi folks.. Had my boat now for 6 months (new to me) have really been enjoying it a lot. Teaching wife to sail is fun too. I have a 2 part question here. I have a lot of slack in my foresaty. I have a (profurl) jib system. We have been caught in 2 'big blows" in 6 months. Jib has taken a whippin or 2 hahaha. My roller furling does not furl the sail all the way in now. I still have 2-3 wraps of jib left and no more furling line and I have to wrap jib manually.. NADA end on line on pulley. I have discovered my jib halyard has done a 180 wrap around my forestay up topside of mast. 1st question is: how do I undo the wrap on stay??? 2nd question: My hunter has a raked mast to aft. Backstay and forestay are very loose. When I say loose,, If I grab and shake the forestay above my head as far as I can reach, the play is maybe 8-10 " inches, Way too much I know. How tight do I need the forestay??

Thanx in advance

Seriously, with all due respect, you need to contact a knowledgeable, local rigger, or even another sailor that you trust, to familiarize you with your furler. You obviously don't know enough about it to operate it safely.

Also, if you have a Hunter, it's possible you have a B&R rig. Some of these boats don't have backstays. If you have one of these, you may as well give up on trying to get headstay tension.

You'll want to tighten the forestay and backstay to about 15-20% of their breaking strength. Shrouds are tightened to about 10% of breaking strength.

You'll need a tension gauge. Like this one:


When you get your tension gauge you get all the information you'll need, i.e. breaking strength of 3/16 stainless steel cable, which is probably what you've got.

My boat uses 1/4 inch cable and the breaking strength is 8,000 pounds, so my forestay and backstay are tensioned to 1200 pounds and shrouds are at 800 pounds.

It'll make a heckuva difference is the way your boat sails.

BTW.....America's Cup racers tension all rigging to 100% of breaking strength!

There is an article posted by a fellow member that goes into great detail.

Adjusting Your Rig

I think talking to a local rigger is a pretty sound idea. One of the possible concerns is that the furler could be loosening your forestay which could have disastrous results...

Nice looking boat by the way:

good luck!

KH, not all the B&R rigs from Hunter were backstay-less. The early masthead versions had normal backstays, and even up to the mid 90s the fracs had a conventional backstay too.

It does sound like the OPs rig is ridiculously loose - and he does indeed need the services of a rigger as you suggest.

Yeah, I quit reading before I got to the part where he mentioned the backstay. Some of the older hunters had a traditional rig and you're right, most of the older B&R's had backstays too.

I was mostly concerned about the fact that he doesn't know how to add a wrap or two of furling line on the drum or a wrap or two of the sheets around the sail and the fact that he is getting halyard wrap with a Pro-Furl. The Wrap Stop should prevent that from happening as long as it's installed correctly and the halyard is tensioned.
It really sounds like he could use some instruction.
