wasn't there a chine version of the Kitty cat? If I recall correctly kitty's were sailing by adults as largish teenagers. These boats were originally intended to fit inside 12 foot skiff/R class skiff rules..
It was/is a very quick boat. May I say very wet as well!! I remember on a short course one eating the Australian Champion Tornado!! Each leg was too short to allow the T to do much..

Just the thing for excitement driven kids.. So the equivalent F12 would work.. The F16 may be better but as pointed out is tortured ply..

Good luck..
