ABSTRACT:
A navigational buoy is provided having a buoy and an inflatable anchor. The buoy and anchor are connected by a hollow stem that is itself flexible or is rigid and is connected to the anchor by a flexible elastomeric bearing. The stem is adapted to provide fluid communication with the anchor so that the anchor can be inflated after being positioned below the sea bottom. The flexibility of the stem is regulated by the materials used to form the stem, solid or liquid fillers in the stem and pneumatic pressure in the stem.
