By analyzing the flow dynamics of the fin and wing, the S-Wing was designed to create active dynamic stability when coming into the buoy, yet have less drag from the finish of the turn to the first wake. As you start your pull, part of the wing becomes inactive as water flows past, allowing the ski to lift and create speed. Coming into the buoy, however, the wing creates increased dynamic stability, making your turns feel slow and controlled. You truly can get the best of both worlds with the S-Wing!
