I know it is confusing! But the good news is that there are lots of Wave races to attend.
The Hobie Class Association of N. America (HCA-NA http://www.hcana.hobieclass.com/
) is a region of the International Hobie Class Assoc. which is sanctioned by the international Sailing Federation. http://www.sailing.org/
) Our N. Americans is in Sandy Hook.
The other group of, incredibly active racers, call themselves the International Wave Class Association. The Pensacola race will be run by them, double check info at http://www.catsailor.com/index.html
GREAT to hear your are racing your Wave!
