The Spitfire was selected to replace the Hobie Dragoon as the RYA Youth Catamaran and since then it has become a top youth class. After the 34th Americas Cup which was held on AC45 and AC72 Catamarans, the numbers of sailors not only in the youth squad, but in the class in general, reached record numbers and at the 2016 RYA Youth Nationals, 13 entries were recorded (almost twice the number of entries in 2014). The UKCRA Youth Squad use the Spitfire as their training platform and their main racing class however the squad also attend events in other classes such as the SL16 World Championships and the Red Bull Foiling Generation. The Spitfire was replaced as the RYA Youth Multihull in 2017 by the new Nacra 15.
