Foil - Surf Foil Boards
Surf foiling is sometimes called prone foiling. It is the hardest discipline to get into as you are riding a smaller board, and need to pop up onto it with your feet pretty close to being in the perfect position. The relatively small amount of time spent actually foiling at the beginning, makes the progression quite slow. Unless you can surf already, this is going to be a tough discipline, but potentially also the most rewarding.
