Make sure that the halyard has the right tension next time. What happens is that when its furled and you try to pull it out the next layer want to come out as well as the clew because of friction and therefore jamming the sail. I used a piece of wood 2 x 3 x 1/2 and a soft hammer to push the sagging sail back into the slot. You have to be patient, make sure that all the control lines are loose, spray soappy solution on the portion of the sail that is comming out of the slot, start from the bottom of the to the top moving up a few inches at a time. After all the sail is back inside the mast than use the outhaul to pull the sail out. I also found out that if you pull the sail from the outhaul and let it rest a few minutes the process gets easier than if you have tension applied all the time.
I now unfurl the main sail by using the outhaul only and when I have guest aboard I dont let them touch the main sail furling lines.
