Dave explaining why concave or double concave doesn’t work on a downwind board.

[@gcammar]

thanks, always a pleasure to listen to the master. would be nice if you could post the whole conversation! Thanks!

[@Flowfoiling]

I didn’t film the entire thing and I wish I had because it’s priceless. I’ll clip together what I did get.

[@Bido11561]

Would this concept apply to prone paddleboard bottoms for downwinds as well? Or doesn’t matter because you’re not on a foil?

[@skobichevskii]

i think blue planet has egg-shaped bottoms due to the same logic

[@IRWE905]

So would a slight Convex be better for Air Replacement or would Stability be Compromised?

[@Flowfoiling]

Great question, we did cover this. Your foil gives off sooo much stability it really doesn’t effect its overall stability. The performance gains outweigh the compromise for stability in this case.
