Thanks Matt
It would appear that the Tornado Class told ISAF to stuff it and have their international event requirements in their class rules appendix. (I assume being in the appendix does make it part of the RRS...)
http://www.tornado.org/uploads/documents...ppendix%20C.pdfBasically
2 races per day, 10 to count for the championship with one throw. Lay day in the middle. My experience is that they want 1.5 hour races. I know for OCR's the schedule called for two or three tornado races (just like the lasers)
Could you point me to the Hobie event document.. I could not find it on the IHCA site.
