Well spotted.
Neil being the guru that he is has been experimenting with these for about 6 months now.
Neil has been loving them - And me too - they absolutely fly upwind and seem to keep the board trim in a much narrower corridor compared to a standard fin.
Works amazing with the Active Trim technology variable tail rocker.
I see they're using pocket foils, any feedback ???
And where to get or try and how much (ball park)?
