The F18 number changed in the following years:
2002
2003
2004
2005
2006
The F16 number changed in:
2005
2006
2008
And the A-cat... it's the winner in this little race... it's number has changed every year from 2001 - 2008, excluding 2007 I can't find tables for 2007.
So Timbo... what was your point?
I thought I said it already, the F18 number has not changed at all since the Infusion and Capricorn and Wingmast came out. I agree with Jake here, the F18's have gotten faster since their last adjustment.
The "problem" with Portsmouth numbers, if there is one, is the F18's now have enough of a fleet so they get their own starts usually so nobody is keeping times, so no adjustments. When a F16 beats an F18, instead of saying the skipper sailed a great race, it's "Wow, that F16 has such an unfair rating, let's lower it."
I am in favor of a measurement type rating, and Texel gives the F16 the least favor of all those rating systems, so I am not trying to win a race based on a slower rating, just pointing out that the F18's have gotten faster in the last couple years, yet not adjusted their numbers. How many guys are still racing Tigers? Didn't Hobie just come out with a new F18? Why?
