I've had several instances of my furling mainsail on my 2007 343 becoming caught so that I can't pull it out with the outhaul. The leech of the sail becomes twisted and doubled at or above the second spreader. Getting the sail extracted from the slot then requires going up the mast on a bosuns chair to yank it out by hand. Since this first happended I've been particularly careful to release the vang and slack the sheet when I'm pulling the sail out or retracting it, but it hasn't eliminated the problem. Has anyone else had the experience or found a solution?
