The RYA Eric Twiname Cup is presented to the winning helm and crew in the Mirror fleet at the RYA Eric Twiname Championships. In 2013 the RYA stopped inviting Mirrors to compete at this championship. The Eric Twiname Trust said the class could retain the cup.
It's currently being presented to the youngest helm to complete all the races at the National Youth & Junior Championships.
