ABSTRACT:
An improved shark screen reduces the possibility of a survivor of a shipwreck or air disaster from being attacked by sharks. A thin film bag is vacuum packed and stored in a cigarette package sized container. After it is unfolded and filled with water, the disaster victim crawls inside. A small inflated annular chamber at the top of the bag ensures that it remains in an upright position and presents an even protuberance-free surface. The top is closed by a drawstring to lower the screen's above-water profile and hides its occupant.
