4.2.3 The competitor needs to apply for a unique "nation code and sailnumber" combination with the international Formula16 class and have it attached to the designated places before registering for an event. The builder supplied combination will be accepted when possible.
It is not clear to me whether the owner of F16 is actually REQUIRED to display the nation code. "needs to" is not the same as "shall" or "must."
As Lee Parks at US Sailing told me, even ISAF International and Recognized Classes often do not display country codes if only racing within the United States and not participating in international events.
Also, you said you will assign a nation code based upon the boat owner's country of citizenship or residency. Is this going to be the preference of the sailor applying for the number? If so, that should be added to that rule.
Also, if participating in an international event, the country code has to be based upon the country that person is representing in the event.
Right now, for instance, Robi might request and be given a country code of PUR, even though he is only racing in the United States. But if he is still in the United States when the F16's start having international competitions, and if he wants to represent the United States, he will have to replace the PUR with USA. Right?
Also not clear to me: If national F16 Class associations are formed in various countries, will numbers within those countries be assigned by the national class association, or will the numbers continue to be assigned by the F16 International Class Authority ad infinitum?
