Kussatz competed for the German sailing squad, as a crew member in the women's 470 class, at the 2008 Summer Olympics in Beijing. Building up to their Olympic selection, she and skipper Rothweiler finished a credible fourteenth in the gold fleet to secure one of the twelve quota places offered at the 2007 ISAF Worlds in Cascais, Portugal. The German duo entered the final race with a myriad of top-ten marks recorded throughout the series. A sixth-place finish at the end of the regatta, however, witnessed their medal chances fade, dragging the duo farther to the back of the fleet in ninth overall with 90 net points.
