I think there are only two areas in North America runing Tiger only events. Your region and upstate New York. I think the rest of the continent is using the NAF18 rules and could care less what brand you sail.
Mark,
I'm not sure I know of any "Tiger Only" events. I was speaking about Hobie Class Racing.
I'd be surprised to learn that there were only 2 Hobie Divisions with Tigers.
I stand by my advice to go with what's the strongest in his area.
I know some of the Tigers in Southern California aren't even class legal anymore. They run with aftermarket sails so they can only race F18 or Opens.
But if that's what is going strong in their region then it makes sense.
