I think the added complexity of adjustable foils, especially individually, dont neccesarily pay off largely. But I am more inclined to not disallow what hasn't been built and tested yet. Performance data both on this and banana boards (which are already disallowed) are not clear, so why ban them? Perhaps someone shows up at Zandvoort with something experimental and sweep the fleet, but I think the risk for that is relatively small. The odds of getting it wrong or breaking the stuff is probably larger. If the technology shows itself to either add too much complexity, fragility or cost, then ban it.

Mast tip weight should in my opinion still be there. Carbon is still expensive, while there are lots of alu masts/sections available. I wonder how much the corrector weights on the carbon masts mean for crew weight range on the boats? Are we talking1.5kgs or 15kgs wider weight range?
