It seems to me that the ICCT being sailed on F18HT's is just a "Worlds" competition. The "C" class boats are such that you will not see one racing in just any regatta, just as you will not see any of the AC boats in just any race. They all have their plusses (we won't talk about the minuses)and the racing is all great but if you use a standard class to do the race it becomes just another "worlds", "continentals", "european championship" or what ever you want to call it.
JMO...
Its all sailing to me.
