So I figured out how to use my hanked sail, while looking for one I can furl:
Ran across something called a Gerr downhaul. Set up like this
So I rigged up a forstay. Attached the jib and added a halliard (green) and downhaul (red).
With slack in the downhaul I can run up the jib and, in this test, use my nacra jibsheet to control the jib.
If I keep the halliard cleated, uncleat the jibsheet and pull the downhaul it bunches the jib up against the forstay. In this picture it's bunching low, but this is because one of my hanks is broken. Once fixed the point at which it bunches the jib will be higher.
I can then uncleat the halliard and the jib bunches up into a ball at the bow.
Or, I can drop the jib straight down by leaving the jibsheet cleated, uncleating the halliard and pulling the downhaul.
I plan on taking one of my old army duffle bags and making a jib bag that stays on the deck. It will have grommet holes for lines to run through it and keep it in place, and a zipper along the top. To use the jib all I have to do is unzip the bag and pull on the halliard. When dowsing it, it will go back down into the bag without me or my passenger having to go forward. At the end of the day all I'll have to do is zip up the bag and be on my merry way.
