In The Netherlands, Lange and teammate Vicky Travascio failed to qualify for the Olympics in the French capital next year, bringing an end to an illustrious sailing career. 

"This will be the last racing of my Olympic career that began in 1980," Lange was quoted as saying by Nacra 17 Class after the race.  

"I have been very emotional all week, but I also remember my career fondly."
