Sorry about that John. This is an older thread and that jib video showed an earlier inferior attempt so I disabled those videos to not misdirect those who are trying to come up with a jib on their islands.
For awhile I was using a Hobie kayak sail (from I14T) as the jib and it worked ok especially in downwind but not the greatest overall as a jib. It was fun but not that much better performance wise. In fact it may have even slowed me down in some situations unfortunately.
So the current version has gone back to using one of my earlier jib sails re-sewn with a better shape and to allow a PVC pole to go through the luft/leading edge to hold it's shape better. Especially when furled. The PVC pipe keeps it from being a lumpy inefficient mess when furling. It seems to work pretty good now.
Currently the whole system has been removed from the AI so I can't take any current pictures. The following pictures show the furling system and show the inexpensive ($80) ronstan furler on the bow frame as well as the mast topper which is what allows independent mainsail furling as well as jib furling. There are several cleats mounted to my haka extensions (not shown) that I cleat the jib sheets to.
