Wow, got my first couple of sessions on the 925 and my mind is blown ?? So fast and so much glide! Coming off the 1250, 1550v2 and 1850.
First session was tow-in into some head high lumps, we ran it on 85cm mast, 60 fuse (A+), 232v1 and one red shim (making it 0deg). Board was an Appletree 4'6" Pro foil surf 37L. Felt great, balanced, fast, no pitch issues. Really really nice.
Then yesterday and today we had some nice 20-25kts cross offshore conditions with 1.5m waves. What dreams are made of ??
I took some time to try different tails and shim settings to see what would work for winging, and I was on my 90L 5'4 Quatro board. I tried first both the 232v1 and a 14" Kane tail with one red +1 shim, but I found for both tails with the +1 shim that the nose wanted to pitch down when going faster, especially when heeling over hard going upwind. I had to put a lot of pressure on my back foot and then still every now and then my board would hit and bounce off the water.
I removed the +1 red shim and then rode the 14" Kane tail without the shim on the A+ 60 fuse, and while that helped a little, it still wanted to dive when heeled over going upwind. With the wing flagged out and going straight I didn't experience the pitch down tendency.
Could it be the board? If noticed the same sensation with other Armstrong wings (1550v2, 1250).
Either way super stoked with this setup, I've never gone so fast on a foil! Hit 45kph today!
Here's a photo of the setup, riding it almost all the way forward in the quatro.
