Slovenia's Tina Mrak and Teja Cerne had their best days sailing at Perth 2011 to climb from the 17th ranked nation, and outside the qualification places, to the 13th ranked. The girls found out the news as soon as they reached the shore and were delighted, Mrak said, "We sailed two great races today. We improved on every lap and we are very happy."
"After yesterday we were angry," added Cerne, "and we didn't believe we could do it so it is a really great feeling at the end of the championship."
Five more nations have the opportunity to qualify at the 2012 470 World Championships from 10-19 May 2012 in Barcelona, Spain.
