Hmmm, well just guessing, I'd say you need a more adjustable weight changing apparatus. You might think about adding a bar, bathroom towel rack in appearance, on which you can add or subtract weight easily to achieve balance by trial and error. Another thing I think I saw in the video is plenty of forward thrust, but marginally adequate cushion air volume. Is there a method to change the ratio of forward/down thrust split?
1. Yes, I need better balance, both with the weights and the thrust angle via elevators.

2. Lots of thrust launching right off the boat ramp, but water drag on the skirt contacting the water builds up rapidly in turns.

3. Head winds have always been a problem with this low powered craft.

4. I've stolen as much lift air from the thrust air as I dare. Original was 33%, now at 40% give or take.

5. The experiment is the skirt (yellow part) and a few things in the ducting you don't see. The original finger skirt was more of a racing skirt allowing you to lean the craft for banking in a turn, but this meant it was unstable front to back as well as side to side. For cruising a stable skirt is nice to have. The experiment started when making major repairs to the hull from an incident I had.
