The Olympic selection (if returned to medal competion) has to be an internationally recognised class. Must also meet the ISAF standards for world wide and national championships. The new "One Design" Tornado , and Hobie Tiger F-18 are the final two boats on the list.
The Tornado was not a recognised International Class when it was selected for the Olympics. It was designed for the Olympics as was the 49er. Thye both gained International status later on down the track. I beleive the RSX is likewise. It would be interesting to see how many Olympic classes were actually Internationaly recognised before selection. The Laser is one of them off course. Were any of the others????
