That's really useful footage. It seems that the ventilation occurs when the T gets close to the surface, sucking air down the rudder. I get exactly the same on a short T foil rudder I have for the SK4 skiff when sailing offwind in waves. You fly off the back of a wave and the next thing there's a lot of noise from the rudder and you can't steer!
cool footage

great footage. I think a vent fence might help that situation?
