Take that back, the AFS F770 wing can be pumped in-flight, but it is not as powerful as the F1080 wing, so have to pump it with less effort so that you do not push it through the water, can be pumped to cover a short drop in wind speed.
Was going to say, I've been able to pump the starboard 650, 900 and slingshot i76 and i99. There's just a big difference in race and much larger freeride foils.
