Abstract
Disclosed is a ship equipped with a propulsion system using wave force, the ship including: a hull; a tube fixed to the hull to be at least partially submerged in water and having a variable volume; a restorer including weights disposed on a bottom in the tube and elastic members pushing down the bottom of the tube to apply restoring force to the tube so that the volume of the tube is restored; an air discharge unit including an air discharge pipe connected to the tube with an end exposed in water and a first valve disposed on the air discharge pipe to open and close the air discharge pipe; and an air suction unit including an air suction pipe connected to the tube with an end exposed to the atmosphere and a second valve disposed on the air suction pipe to open and close the air suction pipe.
