Hi!
I am in my third season with my 1986 C-25, and the first summer I had her, the roller furling got stuck a couple of times at the top. Last summer I had no problem, and now at the end of the summer, again, it is getting stuck at the top and I can't get my 135 genoa unfurled more than half way... Is there anything I can try before going up in the bosun's chair??? I have shook the forestay and it unfurled a little more, and every time I wind it up I keep good pressure on the jib sheets, but for some reason it is getting fouled up at the top. Is there a backstay adjustment or anything that might be out of order that I can check??? Thanks!

Karen: Can you see if the halyard is wrapping on the forestay? That's a common problem that is generally solved by having a small block on the mast that leads the halyard down from the masthead, and then turns it out to the forestay just above the swivel--keeping it away from the forestay and preventing the top of the swivel from turning with the sail. Do you have such a block, and are you using it?

Karen,

Please tell us what brand of furler you have.

I have a CDI FF4. Since it has an internal halyard there is nothing to wrap around the forestay...But, if the knot tied to the head of the jib is too large, it can interfere with the rotation at the mast head.

Karen,

When I run into this problem it usually indicates that the furler has wrapped around the main halyard. Also hasn't happened for some time but you never know. The CDI furler is more likely to be the culprit, especially in the older models with the hook on top.

If you still have the instructions for your furler, check out "halyard wrap." There should be an explanation in the installation manual. If not, you could try to get a manual online, or at least order one from the vendor.

A Google search of halyard wrap shows:

From one of Stu's links (Harken):
<BLOCKQUOTE id=quote><font size=1 face="Verdana, Arial, Helvetica" id=quote>quote:<hr height=1 noshade id=quote>
Halyard Wrap
Everyone knows about gift-wrap, sandwich wrap, plastic wrap, bikini wrap, but what the heck is halyard wrap? Halyard wrap usually occurs when the sail is a little on the short side and doesn't run all the way up the length of the foil. The problem is in the geometry of the foil and halyard relationship. In other words, the halyard is running parallel to the foil and wants to rotate with the foil. The result, unfortunately, is the halyard will bind tight on the foil preventing it from rotating. This is no good.

There are two approaches to fix halyard wrap and neither involve a cutting torch or a chainsaw:

1. If your boat uses only one furling headsail, what works best is a halyard restrainer. The halyard restrainer simply mounts to the mast and pulls the halyard away from the foils so that it doesn't wrap around the foils.

2. If you frequently change furling headsails (say between a 100 and 150), the solution is to add a pendant to the top of each sail. The pendant increases the height of the halyard swivel, so the halyard isn't quite parallel to the foils. Adding a pendant is easy, but it is important to make sure the pennant is at the top of the sail and not on the bottom. If the pendant is mounted at the bottom, there is a danger of blowing out the luff of the sail. The halyard restrainer and pendant are the two best ways to solve halyard wrap.

I have both--the "restrainer" is the little block I referred to earlier. The pendant was on my genoa when I bought the boat, and allows the swivel to raise to the highest possible position. These points apply to most furlers that use the standard jib halyard--CDI does not.

Wow, can you believe I don't know what kind of roller furling I have? Was just messing around on her tonight and didn't look. Which ever kind I have, I do know that I don't have an instruction manual.
I will try to check out the top of the mast but it is a little hard to see without a bosun's chair... Thanks so much!
