Wasn't it the Capricorn F18 that had the reverse canted daggerboards (they pointed toward each other at their tips). F18 quickly made a rule change to disallow such designs. The theory that I recall was that they help produce a vertical lift component and also helped lift the boat to windward more...come to think of it the ORMA 60 tris all have these complicated curved daggerboards in the amas that achieve the same inward tilt - I understand that those are necessary because the AMAs do not have enough volume to support the boat alone and the foil is required to keep the ama above the water.

I think all this means that you have to tack your boards now.
