"The only way to foil faster is to be comfortable and balanced. Foiling is just like balancing sideways at the fulcrum of a teeter-totter .... while you're windsurfing. If your weight is too far forward, the teeter-totter goes down, and your board touches the water. If your weight is too far back, the teeter-totter goes up and you will foil out. The most counter intuitive part of bringing your speed up and mastering foil control, especially if you have any muscle memory from regular windsurfing, is the need to lean forward and drive the foil down as your speed increases."
"Practice flying lower as you try foiling faster and are pushing your control limits, as its safer to touch down than foil out."
"Faster foiling requires a more forward stance to counter balance the increased lift from the foil at higher speeds. If you find yourself foiling out as you go faster, then move your footstraps, especially your front straps, further forward to achieve a more balanced stance."
"You can't avoid foiling out by sheeting out, as this leaves you standing on the tail of the board without any mast base pressure to help trim the foil down. Instead, sheet in and drive the nose down with your front foot and mast base pressure from the rig."
