Thank's David I should have said that photo was the worst I could find that actually showed the sail luffing. It was just after the start and a puff had just passed through that flattened a 5.7 and A just out of the photo before my wife pulled on much downhaul, it was one of those days where it goes from nothing to full on which was why she grabbed me going upwind. When she pulls the downhaul it sorts out the wrinkles no worries and sorts out most of the luffing so it doesn't show in a photo but it's still there. Chris I added a 6 inch lead to the bottom of my jib to fit in my downhaul arrangement, could the lifting of the jib create this problem?
regards
