SHRS has been developed by radio sailors who also have considerable current experience in various dinghy classes either as competitors or officials. The resulting system follows very closely the format used by such classes as the 29ers, 49ers, Laser, Optimist and others. The main difference is that as those classes use different courses for the different heats they only change at the end of the day. As radio sailing use only the one course the heat movement can occur after every race giving an even greater mix.
