Abstract

A friction-reducing ship is provided with laminar protrusion sections on outer hull of the ship, and jet outlets are located at the apex region of the laminar protrusion section for ejecting gas into water to produce micro-bubbles. Gas is supplied to the gas jet outlets from a gas supply pipe located directly nearby to shorten the path as far as practical.
