Title: Mooring buoy

Abstract: A buoy having a generally hollow float body and a control arrangement thereon for flooding regions in said body sufficiently to overcome the buoyancy of the buoy by the weight of the buoy. The buoy can be sunk at a predetermined speed, for example upon or during the approach of a ship which would otherwise collide with the buoy. An arrangement is also provided for subsequently reestablishing the full buoyancy of the buoy, and for thereby raising the buoy to the water level.
