Reaseach efforts regarding the handicap system for the fair determination of the ranking of yacht racing for various sizes have started in the end of 19th century led by Europe and America.The development of the handicap system started in 1952 as inshore and offshore races began. A simple empirical handicap system has been selected by IOR and IMS rule in mid 70's, and more advanced technique based on theoretical and computer simulation has been selected in late 70's by IMS rule. While each techniques have relative merits, it is found that the simple empirical handicap system is more effective than the advanced technique in term of reliability and easiness of use as more racing records are accumulated.
