Hi Carl.. <br> <br>I understand the formula rule Plus grandfathering system that F16 is using. I understand why NA rejected this scheme for older boats in the US.. (cause they were not gonna measure boats). <br> <br>I don't really follow what you mean with this idea. <br> <br>Carl Wrote: <br>-Why not clearly define these , and at the same time correct the crew weight equalization problem ,--Not by listing extensive corrector weights, sail areas of jib and spin sizes , but by a comprensive total equal list of sail area to weight in an equal ratio scale . -Isn't this the reason we have design measurement .Lets use it to it.s full benifit in forming these classes so ALL designs can race equally , not just High Performance or regular catsdesigns . - <br> <br>This is just not clear to me what you intend. <br>Thanks <br>mark<br><br>
