Wings - At 200 apparent wind and 100 AOA, a wing generates normal lift and drag.
Since lift is perpendicular to air flow, the driving force component is small and heeling is high.

Sails - At 200 apparent wind and 100 Angle of Attack, the Genoa generates very small lift and no driving force. The main sail generates lift and drag at 200 Angle of Attack. However, since it generates greater drag relative to a wing, the driving force component is smaller while heeling force component is higher. |
