Great question. What's different in our case is that the flight controller captures the boat’s movements from 7 sensors. Then it establishes the full-state 3×6 state matrix (position, velocity and acceleration with regards to position in x, y and x and rotation around the same axis). This is partly done using sensor fusion algorithms.

We then use the outputs to control the angle of attack, along the longitudinal axis of the foil, essentially twisting it. The R&D that has gone into making this work reliably enough for a consumer product is our secret sauce.
