Isn't that the point of a Formula Class? Comparing boats the same length, width, height and sail area while allowing innovation from within those parameters to take place. Thats what catsailing is about "Inovation".
Which bothers you the most about the 22...cost [your figure is low] , setup time [I have put mine together singlehanded in 3 hours and down in 2.5 hours on an expandable trailer], "NO FITNESS INVOLVED [have you sailed one in heavy air??], or turtling [which all boats do]???
As far as being an old design; what about the Tornado before and after Marstrom started his quest??? The 22 basic design has not been significantly changed since 1992 I believe [Roberts will know]. Its a good design that a Formulas Class could be developed around with plenty of room for innovation.
