Abstract
A ship resistance reduction apparatus using air is disclosed. The objective of the present invention is to spray air at the bottom side of a ship to cause generated bubbles to remain at the bottom side thereof, and thus reduce frictional resistance to water, so that an increase in sailing speed and an improvement in fuel efficiency are promoted. The present invention suctions the air generated during ship maneuvering without using a separate driving source while having a simple structure, to form, at the bottom side of the bottom of the ship, an air layer comprising air bubbles, and thus can be economically manufactured and increase operating efficiency.
