I had the same problem with that foil. Also with the NL’s, lotsa faceplants… I swapped to lift foils which are great, and since then to Axis and I’m really enjoying them. Wish I had better news for you.
When you say you are periodically moving the mast further and further back…you’ve rammed it to the back already, right? Then maybe drilled some holes in the mast plate to get it further back?
You’re heading in the right direction…
No I haven’t drilled holes in the plate yet. I assumed that once I hit the back of the fin box that maybe it was something I was doing wrong so I started moving my stance. Maybe I need to explore that idea. Thanks
