In one of the qualification races the fleet is split into two groups, which start with a five minute interval. At the finish of the first race a boat in the first group hits the "pin-end"-mark of the finish line and drags it behind it's rudder some 30 - 40 meters downwind, before she manages to get it released.
The RO tells the mark boat to get the finish mark back to it's original position, as soon as group one are all finished and before group two get too close. The mark boat only partly manages this and the mark is dragged back a good twenty meters. The first three boats of group two are about one hundred meters from the finish, with two boats at the committee-boat side and one at the left side.
The first one (Yellow) finishes at the committee boat side and 40 seconds later the second (Blue), finishes also at the boat side. The third (Green), crossing the line at the pin-end side, another 10 seconds later.
Green request redress, claiming she would have finished second if the mark was put left in it's position. She states on her request form that she specifically sailed to that end of the finish line to accomplish this
