Abstract: The inflatable buoyant tent apparatus provides a buoyant shelter for use on water. The apparatus is deflatable and inflatable except for the battery pack, alarm, pump, and pressure sensor. The apparatus is therefore compactly transported. The included switched air pump provides for automatic inflation. The most complete apparatus embodiment provides a spine and ribs that ensure rigidity of the tent. Rigidity for the float chamber is aided by corrugations that extend from the chamber first end to the chamber second end. The pressure sensor provides constant monitoring of the inflatable apparatus, with automatic pump operation initiated at a given low pressure setting, and automatic pump cessation upon the apparatus reaching a given air pressure. The beacon atop the tent provides clear visibility of the apparatus, especially at night, to ensure the safety of the apparatus and anyone within the tent. Tent flaps are provided for each end of the tent.
