Abstract
An air lubrication system of an outer installation type has good efficiency. An air recovering device includes a recovery side chamber provided on a bottom of a ship on a stern side from an air ejecting device which supplies air bubbles to the ship bottom. The recovery side chamber includes air intake holes formed in a portion of the recovery side chamber opposite to the ship bottom through a gap. The air recovering device also includes a recovering section recovering air inside a recovery side chamber. The air bubbles acquired from the air intake holes are accumulated inside the recovery side chamber to generate pushing pressure so that air can be smoothly recovered from the recovering section.
