A deployable flotation device including buoyancy members tightly packed in a container mechanism in which the container is either permanently mounted within a watercraft or removably deployed for periodic recertification and receives inner and outer buoyancy members for providing positive buoyancy in a watercraft over a shelf life of up to five years. In a modification a single outer container may be used. A particular composition for the buoyancy member suitable for the marine environment is disclosed. Deployment may be manual, semi-automatic, or automatic depending on the requirements of particular watercraft.
