I can't believe the ruck would been caused by stretched sails so I would hazard a guess that, if this boat is being sold after barely a year from new, there may be other not-so-obvious problems that have been caused by the 'gross ignorance' mentioned by Yngmar. I've not used in-mast furling but it can't be that flimsy or difficult to operate, judging by the number of manufacturers that fit it.
