Contrary to popular belief, there are catamaran regattas in Northern California which are not Hobie-only. I should know, I've been to six of them so far this year. Sometimes we see Hobies Tigers at these regattas.
Glad you brought that up, Rhino. (All Hobies, Nacras, A-class, SolCats, Prindles, Taipans, Capricorns, Tornados, etc. welcome at th MHRA events! see
www.catamaranracing.org.)
Sorry I missed Rio--hope you guys had a good time.
