First conclusive test

I've done towed tests of my new foils.

The flight is stabilized, I could fly 1min 50 without falling!

The boat behavior is really great. I didn't need to adjust the incidence of my rudders for stable flight. 

My two front foils are quite different. The starboard lifts more but it has more problem with ventilation.My port foil has very little ventilation. (Only when I had a big algae.) 

Although the drift force created by the sail will accentuate ventilation, I am very optimistic about the boat behavior on starboard tack. 

Waiting for a weekend windy enough to fly under sail ...
