On your video, it looks like you first got out of balance due to a slight roll, then started up down up ending up with a breach.
Using smaller wave sails usually reduce the down pressure of the sail, and your kit is then more reactive, and need good skills to control. regarding straps position, I ended up thinking that inboard forward straps need to be more forward than outboard forward. I always use rear strap.
Shiming the stabs needs to be done with some thinking : more nose up shiming gives more stability provided you can counter balance the nose up force with the sail (big camed sail mast foot forward for expanble), less shim reduce the nose up force when speed increase and the drag... I shim my Aeromod foil between 0 and 0.7? (never more). Thats less than 1m for 5cm.
If I had time to prepare for overpowered situation (when I anticipate a gust), I can go upwind or bank the board wind ward in a straight line (very effective to reduce nose up motion, but also require to shift bodyweight forward to maintain straight motion).
If I get off balance and feel the foil is going to breach, emergency measure is to bend both legs (the so called frog position, or toilet...) and sheet out putting as much weight on the sail as I can.
IMHO you're doing quite well on the video you posted. It looks quite windy. I don't know how long you've been windfoiling, but do you remember how long it took you to be able to handle such a wind with a fin ?
More flight time builds up the skills...
Thanks 6u1dO. Clearly more skills needed. I've been out about 12 times. 90% of my crashes (not including trying to jibe) are from overpowered foil out. The video is with a 3.7 sail which feels like a handkerchief compared to my 7.5 fin board sail. ?? With the 5.3, I get overpowered easily. Regardless of sail size, I can't keep the nose down when the puffs roll in. The only time I feel like I'm using rear foot pressure is launching. As soon as I break surface tension immediately move all weight forward. Scootch back foot closer to front foot to fly level. Turning down wind with the big sail I get the porpoise happening. With the small sail, downwind much more manageable. I actually had a foiling jibe finally. I made it through the turn, sail flip riding switch foot, but failed at the foot transition. Also need to work on flying as low as possible, but without clipping tops of waves in big chop. It's like hitting the brakes. Sounds like what I'm experiencing is pretty normal, just need more time. Probably try the shim to see what effect that has.
