If sailboats are balanced systems with regards to forces. How can a high AR daggerboard make you fly a hull earlier? Doesnt this suggest that the daggerboards with longer chords should have been longer (and thus have a higher AR) from the beginning, developing more lift earlier?

I do think the daggerboard discussion blocks out the more important news of how Boyers announcement might influence the F-16 class.
E.g. what will now happend with the one-design Taipan 4.9 class?
