I finally sorted out my oversized genoa problem and reefing problem. I fitted a spar to the foot of the genoa and by rolling up the excess sail from the foot and tying it off with bunji straps effectively making it a jib. I fix the jib sheet to the spar (and not to the sail); I fix the other end of the spar to the jib forestay and attach it also to the hull by shackles/rope. The spar is cut to length so it will miss the side stays and swing easily. I use one jib sheet that goes inside of the side stays and I bring the sheet back to the cockpit.
I can roll up the jib for reefing in the same way by attaching the jib slug to the spar and tying off the other end, but I cannot do this from the cockpit...yet, but it does reduce the sail to a manageable size and it seems well balanced compared to the other ways I have tried.
By having a spar on the jib it will be more stable and less likely to flog in the wind, I think performance will be improved by having it. I can drop it quickly when needed and raise it just as easily.
