Abstract

La présente invention concerne un dispositif de propulsion de navire comprenant : une pluralité de moteurs hors-bord installés dans une poupe d'un navire ; et une unité de commande qui commande une sortie de chacun de la pluralité de moteurs hors-bord. Pour retourner le navire pendant la navigation, l'unité de commande commande la pluralité de moteurs hors-bord de sorte qu'une poussée générée par un moteur hors-bord installé soit à tribord soit à bâbord est maintenue, et en même temps la même poussée temporelle générée par un moteur extérieur installé sur l'autre côté est réduite. Par conséquent, l'efficacité du carburant associée à la navigation du navire peut être améliorée par un virage efficace du navire.
