PY (Portsmouth Yardstick) rating iPortsmouth Yardstick is an empirical rating system allowing small sailboats (dinghies included), of different sizes and designs, to race each other fairly. Therefore, by comparing these values, we can have an indication of the relative speed of 2 boats.: 693
Upwind sail area to displacement iThe ratio sail area to displacement is obtained by dividing the sail area by the boat's displaced volume to the power two-thirds. The ratio sail area to displacement can be used to compare the relative sail plan of different sailboats no matter what their size. Upwind: under 18 the ratio indicates a cruise oriented sailboat with limited performances especially in light wind, while over 25 it indicates a fast sailboat.: 714 ft²/T66.34 m²/T
Downwind sail area to displacement iThe ratio sail area to displacement is obtained by dividing the sail area by the boat's displaced volume to the power two-thirds. The ratio sail area to displacement can be used to compare the relative sail plan of different sailboats no matter what their size.: 1283 ft²/T119.2 m²/T
