ABSTRACT:
A marker buoy, attachable to a submersible article by controllable explos cutter, is provided with a buoyant housing having an interior chamber for storage of a coiled length of flexible cord connecting the buoy to the submersible article. The chamber is provided with vents to permit water flow therethrough. An element of buoyant material within the chamber helps to orient the top surface of the buoy in the upward direction. Release of the buoy by the explosive cutter permits it to float to the surface, with the flow of water through the chamber vents ensuring rapid ascent.
