I have a 2000 Hunter 460 with the Seldon main furling system. I have owned the boat for 3 years and until recently have not had any problems with the mainsail furling system. Currently the mainsail has hauled out without any problems, but now has a tendency to bunch up and get clogged inside the mast, preventing it from out hauling beyond the top spreader. When I furl it back in it clogs about mid mast. I've had riggers and sail specialist make adjustments and even trimmed the sail. No luck. Any one have any history like this or suggestions.
