PN (F16) = 63.0
PN (F18) = 62.4
PN (I20) = 59.3
I remember the F16 USPN to being alot higher till recently, from memory 65.2 as D-PN. Upon checking I discovered that US-sailing has back-dated this adjustment to march 2008.
The ratio of (2-up) F16 to F18 US D-PN is now the same as the Texel, SCHRS and Aussie VYC ratios !
Therefor the same the world over for the very first time !
That is a very good development.
These changes are :
Old
65.2 69.3 67.5 64.4 62.3
New
63.0 66.0 64.5 61.9 60.1
Change
-3.4% -4.8% -4.5% -3.9% -3.6%
I think we can thank the F16 sailors up the Chesapeake for finally achieving the impossible; having USPN converge to a realistic rating. Of course, the hammer called Team McDonald had weakened the defenses sufficiently over the years.
