The Portsmouth Yardstick handicap system allows sailboats of different designs and classes to race together by adjusting the time it takes each boat to complete the course to reflect the potential speed of each boat racing. This is a windspeed based handicapping system, which means it accounts for performance differences between designs in different ranges of wind speed. Typical boats ar Day Sailor, Lasers, multihulls, RS Aeros, 420, 470, MC-Scow, ie, if it floats, is sail-powered and not a keelboat, this is the class.
