An emergency buoyancy system mounted to a vessel includes a depth sensor to sense a predetermined maximum depth, and an actuator actuated by the depth sensor. The actuator, upon actuation, opens a membrane between tanks, each holding one of a pair of gas producing chemicals. The gas producing chemicals, preferably bicarbonate of soda and vinegar, mix together to produce carbon dioxide. The carbon dioxide fills a plurality of balloons, thereby providing buoyancy to the vessel to which the balloons are attached.
