Sail shaping balances the speed and power of a sail with control and handling. Shaping lower down in the sail will produce a little less power, but increases maneuverability. Shaping higher up in the sail creates more drive and low-end power. In the performance oriented sails this extra power is easy to control, due to the profile stability supported by cams and tube-battens. In the maneuver and wave-oriented sails, low shaping distribution provides uncompromised manoeuverability.
