How to read the ORC certificate of DELTA
The GPH (General Purpose Handicap) is a single-number rating expressed in seconds per mile. A lower GPH means a faster boat. DELTA has a GPH of 590.6, which allows comparison against other ORC-certified yachts.
The ORC certificate includes the polar diagram and the speed table for different wind speeds (TWS) and wind angles (TWA). This data is used in regatta routers such as Wind Regatta to calculate the optimal route from the weather forecast.
