The invention discloses an air layer monitoring device suitable for an air layer drag reduction ship and the air layer drag reduction ship using the air layer monitoring device. The air layer monitoring device comprises at least one detection part, further comprises at least one conductive probe. The conductivity probe comprises a plurality of probe bodies, the probe bodies protrude into the air layer of the air layer drag reduction ship in different lengths, part of the probe bodies penetrate through the air layer, the dielectric conductivity at different heights is correspondingly measured,and the single-phase air layer thickness of the probe position corresponding to the current air layer detection point is obtained according to the measured dielectric conductivity at the probe position. And the gas layer monitoring device is used for analyzing the heights of the highest probe in the gas and the lowest probe in the water by measuring the conductivity of each probe and utilizing thedifference between the co
