Failed Engineer,

I am not sure who said boards are riding on a cushion of air, not me, but I do believe there is "lift" from air passing under the board.

I bow to your expertise, but if I am moving at 25+ knots of boards speed off the wind on my Formula board, I can keep it on the water and in control without too much effort. However, if I am on a beam reach at slightly slower speeds and then turn into the wind, lift off can be a serious problem unless I add significant downward force to the boom. Any sheeting out or taking weight off the mast foot and disaster strikes. Board speed is slower, but the chances of lift off are higher. The only thing I see is increased air flow under the board causing it to take off.

What am I missing?
Formula 160; iSonic 111; HiFly Move 105; Tiga 263; '85 Mistral Superlight.
Maui Sails TR 11.0; 9.2; 8.4; 7.6; 6.6; Maui Sails Switch 6.0; 5.2; Maui Sails Global 4.5; 4.0.
