I believe that a similar thing should happen in Europe if not Worldwide.
I already sail on the same handicap at both the clubs where I sail whether Uni or Sloop. I simply had a word with the sailing secretary at each club and they are sailing me off the UK PY of 698 - same as F18.
If US sailing, RYA, SCHRS and Texel are made aware that this is the intention of the class and in addition that ALL F16s race off the same handicap irrespective of manufacturer then I think we'll have it sorted. All the other yardstick and calc systems will fall into line as well.
Once the main F16 Associations US, UK, NED, AUS, SIN are formed, and the F16 Council is in place, we would be in a strong position to write an open letter to each of the yardstick authorities asking for this to be implemented.
