I see, though i don't see the photo as it didn't come through.
But i thought you meant braced near the cockpit, so seemed like you meant on ww hull.

Any idea how it might perform if it was at ww hull?
I saw video just yesterday of rob in kiteboat on moreton bay and their board is braced at ww hull.
Even caused flying of hull.
Maybe it could have a slight incline like Rob's and generate some lift.
Worth thinking about on thd more minimalist H's.

Board sounds like useful idea for HPs in general.
