I have a large overlapping Genoa (125 %) on a roller furler and a couple of older but good hank sails. One about 100% the other a storm jib. If needed I hoist a wire stay on my second Jib halyard and hoist the sail using the spinnaker halyard. This sets like a solent with the temporary stay just aft of the forestay on a very secure pad eye.

Sails stripped for the winter.
I'm contemplating using the older 100% jib this season for no other reason than curiosity but don't want the expense of converting it.
What's the simplest way of setting a hank-on sail around the forestay blade without damaging it?

My thoughts so far are to hoist the temporary stay(5mm steal) between the upper and lower swivel points and hoist the sail using the second jib halyard or use a series of soft shackles on the hanks.

First runs the risk of buckling the blade. Second of denting it at the point loads. Not sure if either is realistic but I'm brain storming so everything is valid at this point.

Any other suggestions?

I would definitely avoid point loading on the roller furler light alloy extrusions.
This might be an alternative: it is a sort bring-you-home solution for a storm sail, a sleeve around a rolled genoa where hanks are hooked; it might of course be adapted for use around the bare aluminium profiles.

Have a bolt rope sewn to a piece of sail cloth 2-3 inches wide. Cheapest to take an old sail to a sail maker to cut down. Double the cloth over to increase strength & triple stitch.
Put eyelets in it opposite the hanks of the sails you want to use. You would have to take the sail to the sail maker as well so he can match for you.
Slide the new bolt rope into the furler & as you do clip the 2 together & at the top & hoist on the halyard with little tension. At the bottom, hook the sail to the furler & then with a thin line doubled up to form a couple of bights, or soft shackle ( when you have established the exact length) tension the bolt rope so that they match in tension. Then tension the halyard which will tension both sail & bolt rope & sail together. It would be preferable that the bolt rope one is shorter than the sail. It could actually be a couple of feet shorter so you could use it on a couple of sails if you had extra eyelets

It can be furled but you will get some bumps where the hanks are wound into the sail.

Honestly I'd just suck up the conversion to bolt rope. Everything else is either introducing loads to the foil that it wasn't designed for, adding complication, or both.

And I can't see a way that you could do anything else and still be able to furl the sail.
 
I've converted hank-on to roller furling just by removing the piston hanks. I was lucky that the diameter of the bolt rope already behind the hanks fitted the slide. I had to modify the head, removing the eye which was too large to run up the groove in the foil and clamping the bolt rope via two aly plates to connect to the uphawl wire.

There is a product calle kiwi slides. I think Bainbridge sell them.
You replace your hanks with them, just tie them through the Hank eyes, this would allow you to fuel the headsail.

However if you aren't using your furler don't you have a spare halyard that would normally be used to hoist the Genoa on the furler?
Hoist your removable stay as you usually do, then use the Genoa halyard to hoist the jib (rather than the spinnaker halyard).
It should have a better lead than the spinnaker halyard.

No need to buy or change anything.
Or have I missed some detail in the setup?

You haven't missed anything. This is my plan A.

I was just thinking if there was an obvious way to hoist on the furling blade that I had missed. Looks like there isn't. The slugs/slides risk the same point loading problem that soft shackles present.
I also thought of coiling a line around the blade so that the hanks would attach every 2 or 3 wraps round to spread the load.

Will probably try a few zero or low cost options to see what does or doesn't work. I just don't want to convert the sails as the option of hoisting on the spare halyard/ stay offers a solution if the furller ever fails.

Not really bothered about furling. I'm ok with traditional hank on sailing.
Converting the sails is the obvious solution but frankly I can live without the expense.

Will look at this, never know, I might get lucky as you did. But I would like to be able to go back the hanks so won't modify past that point.
 
Kiwi slides. I bought some to fit to a genoa for my Twister. They consist of a plastic slug which slides in the furler foil groove having two webbing tabs attched which are simply stitched onto the luff of the sail at suitable spacing.

Not having any shackles enables the sail to be tightly furled without.

I have not yet got around to fitting them and, given my age and other factors, it's possible I never will so I can't report on how well they perform, but the sailmaker I bought them from uses them.
