    Being inside of a sail wing would protect the pilot from the extreme wind chill of traveling at 70MPH and streamline the aerodynamics, but the major disadvantage that I see is they would not be able to use their bodies as counter ballast making it more difficult and dangerous to tack for changing directions
    Never try to tell me it can't be done
