Abstract
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.
