LYS

Svenskt Respitsystem (SRS), formerly known as Leading Yard Stick and Lidingö Yard Stick (LYS). SRS is a semi-empirically based handicapping system used in yacht racing in the Nordic countries. The first version of the handicap system was developed in 1970 by the Swedish yacht designer Lars-Olof Norlin. He based the system on regatta results from the Round Lidingö Race. His own design, Allegro 27, was used as the benchmark and was by definition assigned a LYS value of 1.00.
