She’ll do.
Not sure of the value. But it can be done.
Goal, I have always understood, you want to have a minimalist entry over the loft of the jib so that you don’t create turbulence as the wind goes across the jib sail.
The furled jib is a protuberance. It would create considerable turbulence. This would reduce the wind adherence to the sail and create drag.

Hi Jssailem
RE: The furled jib is a protuberance. It would create considerable turbulence. This would reduce the wind adherence to the sail and create drag.
That was my first thought, BUT the reef furled genoa has that problem and so does a mast on the mainsail.
I sail often in 20 plus knots and my furling genoa is pretty light so I am looking at something that will prolong the life of my furling genoa.
We will see how it works out after a few mods and a stiffer breeze.
It is a freeby so nothing to lose at this stage.

Hi Greg.
That is where the inspiration came from.
There were some other considerations.
I often sail in 20 plus knots with the genoa partially furled.
It has luff pads and furls pretty well.
However, it is pretty new and I was worried about stretch.
That is why I started looking at some way to rig a proper jib.
The other point was that the boat next to me was demolished and lots of stuff when into the bin.
I got the main (really past it) and jib (not so bad, but nothing special) for free.
So it became an exercise in "can I reused old sails".
Up to now it is looking pretty good. I have spent $13. Compared to $1300, I am doing OK,
Here is a vid I a guy trying to set a storm (wrap around sail) with a zipper. Not so impressive.

Hi Greg.
I sewed loops that went through the cringles.
Then on the bow I threaded a line from tack to head through the loops and tied off at the head.
These photos are the test at home. On the boat I uses 4mm braid, but it was too limp and a hassle to thread.
I will epoxy about 2 inches of the end so it is stiff.
Also will try small line with toggles going through the horizontal pockets.
I had no trouble hoisting once it was together, but threading too too long.
A work in progress.

I have an old jib I could try to make into a “storm jib”, but I suspect that if I am out for a sail and it blows up a stink, I am not going to go to the bow and try to set a storm jib. I would roll up the genny and motor home. And if it is blowing enough to need a storm jib before I head out…I will sit at the dock and drink a beer.
If I was out for days cruising, it might make sense, but for my day sailing lifestyle, I don’t know how often it would come out of the bag.
Neat idea though. Keep us posted on the refinements.

That was much the same as I was thinking. If your higher winds are mostly seasonal like we have in the PWN, i know of several sailors who have a 150% for summer but put on a 100% or smaller for winter sailing.
