I've got a few old sails out in the trusses (been meaning to turf them). I'll have a look tomorrow and let you know their condition and sizes, I think they're dacron they're 20-25yo! I'm heading to Geelong in a week and can get them that far.
Sam, Give me the sail and I will drop them down at Mordi when I next go Laser sailing. I will not be at the club this week as it is the masters at Mount Martha, but I will be there next week + I am also going down to the club on friday, so if we sail tomorrow or Thursday you can hand them over.
