A single person survival craft comprising a bottom panel, and two side panels, the bottom panel, in turn, comprising a plurality of hollow tubular structures, said bottom panel having two pointed ends, and a wide mid-section, there being two full length peripheral hollow tubular structures, and a predetermined number of intermediate reduced length hollow tubular structures in the region of said bottom panel mid-section, said number of tubular structures progressively decreasing towards each of said pointed ends, said tubular structures in said bottom panel being of curved shape said two full length peripheral hollow tubular structure, and at least some of said intermediate hollow tubular structures being curved around a radius which decreases progressively from said mid-section to each of said ends, adjacent said hollow tubular structures being joined to one another in side by side abutting relationship: and each of said side panels having pointed ends and a wide mid-section, and there being a predetermined number of hollow tubular structures at said mid-section and said numbers of said tubular structures decreasing progressively from said mid-section towards each of said pointed ends, each said side panel being joined to said bottom panel along a first edge at the adjacent respective ones of said full length peripheral hollow tubular structures of said bottom panel, and, there being releasable closure means extending along portions of a second edge of each said side panel, whereby said second edges may be at least partially opened up and closed together, and air permeable mesh means in at least one of said side panels.
