ABSTRACT:
A portable anchoring device for supporting swimmer harnesses while allowing the swimmer freedom of swimming movement. The anchoring device is a waterproof container with a closable top opening for filling the container with water or other material. The bottom of the container is covered with a material having a high coefficient of frictional resistance to prevent the container from slipping on a wet or dry surface. Removable rotatable flexible posts are mounted in threaded orifices on the container for securing the swimmers harness to the fixed container.
