[C320-list] Sail chafe

[Robert Seastream]

All:

While taking the sails off, we noticed there are several points where 
the sailcloth has worn away along the 'bead' (sewn into the luff) which 
you thread into the furler.
We're wondering what could cause this, as the sail threads up into and 
drops down (practically by itself) out of the furler fairly easily 
every season.
The sail is original (2002), so we didn't think age should be the 
issue.  Thoughts, repair procedures?
