I dont think the Tiger will dominate the fleet, but perhaps the top guns will continue to dominate the F18 fleet? Bundy and Ashby, Mitch Booth and others will work on promoting the Wildcat at the big F18 events, just like other olympians and olympic hopefuls will promote NACRA or other designs. I dont see the large difference for the F18 class if the Tiger is choosen. The same persons might still win, but does that mean the Tiger will be the boat of choice for everybody. Why does it have to go the same way as the B-class did when the Tornado was choosen? I think the F18 fleet and concept is strong enough to handle the Tiger as an olympic class, just like the B class was not back in the 60s.
BUT, if the F18 class dont want the Tiger as an olympic class and a legit F18, I have all respect for that. No multihull sailor wants any damage done to the F18 (or any other) fleet I think/hope.
