Stayless Storm Jib ?

[daddle]

One might build a running stay that includes a halyard block at the upper end. The entire rig would be hoisted up with the mast halyard, hardened with the runners or backstay, followed by the storm sail being hoisted up the running stay on hanks.

BTW, a furled genoa is a huge disadvantage in a blow that requires a storm jib. It should be dropped and stowed if possible...hopefully in a lull.
