The batten pocket rule as per the April 2010 set allows for a max of 30mm wide batten pockets in mainsail and 25mm on jibs. Not one sail at the worlds complied. 

The cloth issue was simply a small area of reinforcement at the tack and clew of the main and jib. The body of the sails were fully compliant. Just a small area of stickyback was applied to the corners. 

The reason everyone (except for the one) let the issues slide is one of sportsmanship. The sails were measured by the head measurer and approved. Everyone knew of the issue with the stickyback from the first day of the worlds, I had people asking for my thoughts before the first race. My comment was that if you want to protest then you better do it on day one or let it be.
