Line Choice for Single-Line Reefing
 
I am going to replace my worn mainsail reefing lines on my Pearson 39. The current single-line system tends to get twisted in the boom. What line choices do I have to best utilize this system?

Thanks

How do you have the single line reefing line run? What I normally suggest is that you have small blocks added to the reefing cringle at the luff and leech reefing points, and then have the line come up from the boom, to the luff/tack reefing point and then back down to the boom, aft along the boom, then up to the leech/clew reefing point and then back down to the boom... and back forward if you want. I prefer two-line reefing systems, as they have far less friction in them and are faster to set IMHO. See this webpage as to other reasons for using two-line reefing.

It would help if you said what boat you're talking about... the size of the boat does matter. I'm using Sta-SetX for the reefing lines on my boa, but will probably upgrade the halyards, topping lift and reefing lines to NER T900 at some point this year. It is stronger and lighter than the Sta-SetX.

The boat is a Pearson 39
 
See this link for current set-up.

I think I would go with StaSetX, rather than a higher tech line, because it is easier to splice and takes knots quite well. But getting the line in through those blocks in the boom is going to be a bear...

The reason I'm recommending StaSetX, rather than just StaSet, is that it has a parallel core, rather than a braided core and as such will stretch a bit less.

a bear...?

Why? Shouldn't I just sew the new line to the but of the old line and pull it through? Or am I missing something obvious? Do you think there would be any advantage to using a single-braid line?

Thanks,

Not sure what your set up looks like but generaly you can stitch a new line to an old one and pull it through. If you are brave you can use duct tape like I usualy do. give it a good tug before you try it to be sure it is solid.

Actually since we are talking about reefing I just use a hook in my cunningham and move it up to a reef cringle if needed. Not a good solution if you are short handed but I generaly have a boat full.

Since I sail on these mills ponds we call the Great Lakes I only have one reef point.

That should probably work, but Mr. Murphy has a way of screwing things up... and getting into the boom to straighten out a jam would suck. Then again... I have really short arms. :)

I wouldn't use a single braid line since they're far less tolerant of chafe than a double braid or braid and core line. In the latter, a majority of the strength is often found in the core, which is protected from UV damage and chafe by the exterior braid.
