The 24-year-old Young, who earned her call-up to Team GB for the 2012 Games just 11 days ago, secured her confidence-boosting result after six days of competition at the German venue, which served up a mix of conditions during the course of the regatta.
Young, whose previous World Championship best came at the Perth 2011 event in December where she finished seventh, was poised in third place – just one point behind the silver medal position – heading into the final two races on Sunday, and counted seven top 10 results from the 10 races held to that point.
In spite of picking up a disqualification for a second yellow flag in the penultimate race of the regatta – a fate also suffered by one of her key medal rivals Sari Multala of Finland – the British sailor still remained within touching distance of the podium spots.
A 19th from the final race saw Young ultimately miss on the medals by just four points behind Multala, with gold going to Lithuania’s Gintare Scheidt and silver to China’s Xu Lijia.
Team-mate Charlotte Dobson concluded her regatta in 10th, with development squad Radial sailor Chloe Martin securing 14th.
