<p>Provided is a frictional-resistance reduced ship which has a frictional resistance reduced to improve the mileage thereof. As a navigation speed rises the higher, the vacuum to be established by a wing (33) grows the higher. In the state where a gas-liquid interface is depressed to the vicinity of an aperture (34), the air and the water (the sea water) move there at different speeds. Since the air and the water are different in densities, fine bubbles (micro bubbles) are generated by the Kelvin-Helmholtz instability phenomenon in the inner space of the aperture (34) of a fine bubble generating member (3). The fine bubbles flow downstream along and close to the hull of the ship.</p> |
