Disclosed is a boat having a plurality of independent air chambers. At least two independent small tubes are included in one cover to form a porous tube body with a plurality of independent air chambers so that air is injected into and exhausted from the independent small tubes at the same time but air is independently lost from the independent small tubes when a puncture is formed therein. The boat is provided with a plurality of such porous tube bodies so as to be connected with each other in series or in parallel by means of a connection pipe having an air input/output control unit. This boat gives absolute safety against puncture or external damage, is constructed and dissembled within a short time, and also has a competitive force in terms of production costs in comparison to function and safety.
