I'm a bit embarrassed at being elevated to the role of world expert of flying storm jibs , but here goes:-
the whole issue should be seen through a lens which is covered with spray and probably a fair amount of solid water as well. By definition it is going to be blowing like hell, and not only will the fellow hoisting this sail need to know what he's doing, but there will be no hope of meaningful communication with whoever is at the helm, assuming there is someone there.
Added to which he is going to have one hand for the ship and one hand for setting up the jib. Simplicity is key to the whole thing
. It needs to be a assembled with a minimum of fuss and time. The system I advocate is a compromise with certain inherent problems (principally the lack of a stay to maintain control of the sail).
I guess my default position would be that (a) if you want to keep a rolled headsail and (
set a storm jib flying and © dont have a strong tack point on the foredeck, then it would be better to tack the headsail to the foot of the forestay and put up with a bit of chafe.
Hope this helps.
