I think you should read my post again. I did find the 6 degree cant "rule" in the definitions section, however I don't think it will be very effective at stopping someone putting more than 6 degrees of cant in the board. My point is that it should be put in the actual rules for centreboards, not the definitions.

I realise that I may be splitting hairs, but the definition of a centreboard/daggerboard is well known by sailors, so having the F16 class redefine it seems silly.
