Why stop then at the jib? Why not continue on with the hulls, they aren't wave-piercing style. Or why not the centreboards, they aren't the high aspect style that we see nowadays. Also why is there a batten on the foot of the mainsail, that ain't modern. Where do you start and stop?

My view is that the design is to show the F16 as a box rule design and what the parameters are for this box. Each manufacturer will then promo themselves what they believe is the best interpretation of this box.
