PERTH, Australia -- Two-time Olympic gold medalists Robert Scheidt and Bruno Prada of Brazil won their second straight title in the men's Star keelboat class at the world sailing championships.
Scheidt and Prada took a commanding 18-point lead into Saturday's top-10 medal race and finished fifth to cement first place ahead of Robert Stanjek and Frithjof Kleen of Germany, who leapfrogged Americans Mark Mendelblatt and Brian Fatih to finish second.
The Brazilian pair sailed consistently throughout the championships including a win, four second and two third placings over the course of 10 races leading up to the medal race.
They sailed a sound race in light and shifting wind conditions to clinch back-to-back world championships, ending a year in which they won six international Star events, including the Weymouth and Portland International Regatta in July.
Australia's top-ranked pair of Nathan Outteridge and Iain Jensen will take a comfortable 17-point lead into Sunday's top-10 medal race in the 49er skiff class.
Outteridge and Jensen had fifth, seventh and 10th placings in Saturday's races to move their overall points total to 85, ahead of Emil and Simon Toft Nielsen of Denmark at 102.
World No. 2 Nico Delle Karth and Nikolaus Resch of Austria had two wins and an eighth placing Saturday, continuing a stunning comeback from 22nd place to qualify in seventh place for the medal race.
Top-ranked Tom Slingsby of Australia came close to wrapping up his fourth world title in the laser class Saturday and needs only a mid-fleet finish in Sunday's top-10 race to clinch the gold medal.
The 27-year-old takes a 14-point lead over Germany's Simon Goteluschen into the medal race after finishing 10th and 12th in Saturday's races. Slingsby had previously won five of the 10 races in the class and said he was disappointed not to clinch the gold medal on Saturday.
