One-design

One-Design

One-Design is a racing method where all vehicles or boats have identical or very similar designs or models. It is also known as Spec series. It is heavily used in sailboat racing. All competitors in a race are then judged based on a single start time. One-Design can be contrasted with the Development class, the classic example being the America's Cup 12-metre class, or to the Box Rule used, for example, in the TP 52 class.
