Yeah... Like which one? ... I can't think of a single developement. I think the Tornado class has developed and led EVERY improvement you see in the production spin boats. You have 50 teams all trying to come up with a better way of doing it... AND... they are working 24/7 at it... What company would not go to school on the Tornado fleet. Hell... they just buy the talent.
The A class rules allows hull and mast and sail changes... but the hard wing sail may obsolete the entire fleet unless rule changes are put in.
In fact the F18 wants to LIMIT development. ... the F18 mantra is to also a SMALL amount of developement to keep more boats in the game.
