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 depending inflatable anchor tube with an anchor weight positioned in the lowermost portion thereof. The sea anchor has a plurality of flood ports positioned in panels enclosing the vertical anchor tube and weight. Flat panels of flexible sheet material extend between the upstanding inflatable beams to form a pyramidal surface. The 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.
