A pyramid constructed of upstanding inflatable beam members extending from an inflatable base upwardly to an apex. The inflatable base carries an integral sea anchor depending therefrom, comprising an inflatable cross tube carrying a centrally depending inflatable anchor tube with an achor weight positioned in the lowermost end portion thereof. The sea anchor includes a plurality of flood ports positioned in lower flat panels of flexible sheet material extending between the base and the end of the anchor tube to form a pyramidal surface enclosing the vertical anchor tube and weight. Upper flat panels of flexible sheet material extend between the upstanding inflatable beam to form a pyramidal surface. The upper panels include an upper radar reflective panel portion, a lower colored panel portion, and a translucent panel portion positioned between the upper and lower panel portions. A solar still mechanism is positioned within the enclosure formed by the pyramidal surface. Pockets are provided for survival gear on the exterior of the pyramidal surface.

A pyramid-shaped floating search and rescue inflatable signal device, comprising: four endwise connected generally horizontally disposed inflatable base tubes defining a generally rectangularly shaped base; a generally horizontally disposed inflatable cross-tube connected to and extending diagonally between two of the four corners of said base defined by the interconnection of said base tubes; an inflatable anchor tube centrally positioned along said cross-tube and connected thereto, said anchor tube extending downwardly from said cross-tube and having a free lower end portion supportably containing therein a ballast weight, said ballast weight having sufficient weight and said anchor tube extending downward sufficiently far to cause the device to be resistant to overturning in the water from wind and waves during use and to cause the device to be self-righting if overturned in the water during deployment or subsequent use; four inflatable frame tubes, each connected by one end to one of the four corners of said base and extending upwardly therefrom to an apex at which the other ends of said frame tubes are connected together; four flat upper panels of flexible sheet material, each extending between adjacent ones of said frame tubes and said base tubes to form an upper pyramidal surface; four flat lower panels of flexible sheet material, each extending between one of said base tubes in the lowermost end of said anchor tube and joined along its common edges with the adjacent lower panels to form a lower pyramidal surface enclosing said anchor tube and ballast weight therein, said lower panels having flood ports for restricted entry and exit of water from the interior space defined by said lower pyramidal surface, said base tubes, cross-tube, anchor tube and frame tubes collectively having sufficient buoyancy and said ballast weight having sufficient weight to maintain said upper pyramidal surface generally above the water and said lower pyramidal surface generally below the water.
