I noticed that Nacra are having a Worlds and Europeans with primarily boats that are not registered as an official ISAF class.
They call it a Nacra F18 Worlds but it will probably be 90% Infusions.
http://nacraeurope.com/news_details.php?id=88I guess ISAF is more relaxed then we think?
Maybe someone from the F16 class could write up a comprehensive report outlining all the pros and cons of joining ISAF?
I've spent a good bit of time on the ISAF website today.
The pros and cons seem to me, subjective. Either you belong or you don't. I haven't yet found any benefit to be derived beyond what U.S. Sailing offers. There is, however, much more information than I can cover in a single day.
In any case, we may not have sufficient numbers for consideration.
You may want to read part 26 pp. 101-106.
