The invention provides a water airship, which is composed of an airship and a boat. The lower part of the airship is connected with the upper part of the boat, and the immersion depth of the boat is lowered by means of the lifting force of the airship. By adopting the water airship, the immersion depth of the boat body is effectively lowered, thus the water resistance of the boat is reduced, and the sailing speed of the boat is increased.
