D-PN is the basic, "all around" handicap number for each boat. The wind HC columns are specific handicaps based on windspeed, and the numbers are Beaufort scale numbers.
https://en.wikipedia.org/wiki/Beaufort_scaleIf you can reliably measure/monitor/estimate wind speed, the recommended numbers to use are the wind handicap numbers.
http://www.ussailing.org/racing/offshor ... h-numbers/The handicap numbers for a Hobie 16 and a Prindle 16 are as follows:
Boat Class | D-PN | 0 - 1 | 2 - 3 | . 4 . | 5 - 9
Hobie 16.. | 76.0 | 81.5 | 78.7 | 74.1 | 71.3
Prindle 16 | 77.5 | 84.1 | 80.7 | 76.3 | 71.3
So by basic numbers, they're pretty evenly matched, with a slight advantage to the Hobie 16. The Hobie 16 has the largest advantage in very light air, a slight advantage in a light/gentle breeze and a moderate breeze, and the boats are exactly evenly matched in a fresh breeze or stronger.
If you were racing in a moderate breeze, with wind speeds of ~10-15 kts (beaufort 4), you would use 74.1 for the Hobie 16's handicap number and 76.3 for the Prindle 16.
