The International Small Catamaran Handicap Rating System provides a systematic way of rating more than 300 catamaran classes and variants. The system is based on 17 measurements combined in a formula which is varied in the light of experience. It is widely used by clubs for mixed catamaran fleet racing, and for larger long distance events. It can be linked to other systems, such as Portsmouth Yardstick or USPN, and is used to provide starting figures for classes or variants where there is insufficient performance data.
