PURPOSE: A resistance reducing apparatus using the waste heat of a ship is provided to minimize frictional resistance generated according to the movement of a ship and to easily control the amount of compressive air discharged to the bottom of a ship in proportion to the operational states of an engine. CONSTITUTION: A resistance reducing apparatus using the waste heat of a ship comprises a turbo charger, a heat exchanger(200), a turbine(300), an air compressing part(400), an air feeding part(500), and a control part. The turbo charger is operated by exhaust gas exhausted form an engine. The heat exchanger heat exchangers the exhaust gas receiving from the turbo charger and working fluid. The turbine is driven by the working fluid heat-exchanged while passing through the heat exchanger. The air compressor is connected to the turbine in a same axis and generates compressive air with the turbine. The air feeding part feeds the compressive air to the bottom of a ship. The control part controls the amount of fed air fed from the air feeding part.
