Summary[edit]

Description
English: Downwind polar diagram to determine velocity made good at various wind speeds for a hypothetical displacement sailboat and sail plan. The blue and red dots denote the optimum downwind velocity made good (VMG) for each wind speed. For example, for a windspeed of 10 kts, optimum VMG is almost 6 kts on a course of 150°, whereas for a windspeed of 20 kts, optimum VMG is almost 8 kts on a course of 174°. After Textor, Ken (1995) The New Book of Sail Trim, Sheridan House, Inc., pp. 228 ISBN: 0924486813. , pp. 52-3.
Français : Exemple de diagramme "polaire" pour déterminer en fonction de la vitesse du vent, la meilleure Velocity made good d'angle et de vitesse du bateau. Exemples d'optimum VMG :
  • vent de 10 nœuds : 150°, 6 nœuds;
  • vent de 28 nœuds : 174°, 9,5 nœuds.
Ce type de diagramme n'est valable que pour un type de voilier, voire uniquement pour un seul bateau.
