The FIG competition – the hardest of them all, according to her coach, Tory du Mond – was the setting for the youngster, who was one of Jersey's water carriers at the opening ceremony on Saturday night, to open the Island's account in gymnastics.
Fifth in the floor event and 12th on the beam, she won bronze on the vault with a 12.950 and gold on the asymmetrical bars with 10.650, all adding up to an overall silver with a total of 45.400.
The overall winner was Grace Harrison of the Isle of Man with 48.750, with Jersey team-mate Charlotte Pollard just pipped for the overall bronze, finishing fourth on 44.850, just 0.1 behind Nicole Burns of the Isle of Man.
Pollard, also 14, a JCG student, claimed joint silver in the asymmetrical bars behind Shurmer with 10.150. It was a great boost for the whole team, especially after they had just failed to get team bronze on the first day of competition, just 0.5 off the medal. The two boys in the Jersey squad, Chessy Williams and Zee Adamson, gained experience of a good level of competition, finishing 14th and 12th overall respectively in the FIG competition.
