I beg to differ. As far as I'm concerned, that title is shared also with the 18 Square. A well sailed Cat I comes to mind as far as competing with the newer designs... and upwind, even I on my Cat II stock NACRA can have moments of glory against same, I have the pic to prove it.
When them thar light boats are suffering overpowered in more than 15kt, my tuff ol' CatII Sq is waking up. Can you say, 'singlehand in 20kt+?' I bet y'all cain't ;-)
