Okay, Jamie, so do I have this right?

Two of the sailors at the Alter Cup are from the same class, Nacra 20, even though it is supposed to be only one sailor representing each class as its national champion (or runnerup).

And the Nacra 20 class is not even listed in the directory of US Sailing, much less having paid dues. And even if we still think of it as the Inter 20 class, which IS listed in the directory, that class has not paid its dues, either.

And, meanwhile, two other classes that have faithfully paid their dues to US Sailing and who do hold national championships every year, are not invited to the Alter Cup. (That would be the Shark and the Wave.)

The Isotope Class, unfortunately, has not paid its dues and, even though it holds a national championship every year, is not represented at the Alter Cup.

I guess you have to be in the "In" crowd to go to the Alter Cup.
