Scott,
Has it been "up" for longer then 4 hours ??????
When was the last time you washed out the mast's luff track and washed the sail's boltrope??? And lubed the lufftrack and the sail's boltrope w/ "SailKote"???
I find I have to this to my mast and sails several times a season .... especially if the boat is at a oceanfront event for several days w/ blowing sand.
