description An air lubrication device (1) is mounted on a ship and reduces frictional resistance of water, to which the ship is subjected, by discharging air from the bottom of the ship. The air lubrication device (1) has at least three discharge opening groups (12-15) which are arranged in parallel in the widthwise direction of the ship. When a parallel discharge mode is selected, scavenging air is supplied to the discharge opening groups (13, 14) which are disposed on the inboard side of the ship, and air having increased pressure is supplied to the discharge opening groups (12, 15) disposed on the left and right outboard sides of the ship. L'invention concerne un dispositif de lubrification par air (1) monté sur un bateau et réduisant la résistance de frottement de l'eau, à laquelle le bateau est soumis, en évacuant l'air du fond du bateau. Le dispositif de lubrification par air (1) comprend au moins trois groupes d'ouvertures d'évacuation (12-15) qui sont agencés parallèlement dans la direction de la largeur du bateau. Lorsqu'un mode d'évacuation parallèle est sélectionné, un air de balayage est fourni aux groupes d'ouverture d'évacuation (13, 14) qui sont disposés sur le côté intérieur du bateau, et de l'air présentant une pression augmentée est fourni aux groupes d'ouverture d'évacuation (12, 15) disposés sur les côtés extérieurs droit et gauche du bateau.
