My bet; that will never happen. We will see foils that will provide some lift but nothing that will clear the boat from the water. While lifting foils work on super lightweight and low aero-drag moths, on anything of any size lifting foils have not yet proven to get to weather efficiently enough to be an advantage around a technical course. They tend to be more of a "drag" upwind as the boat can't get airborne at high angles of attack and turn out to be a source for a lot of slowness. Yes, Hydroptere absolutely rocks, but she doesn't go to weather well at all...all video you see of her is a very deep beam reach since she generates such incredible apparent wind.
