1. In a wave-driven pump comprising a float portion detachably interfitted with a hydrodynamically resistive portion for reciprocating motion therebetween, the pump adapted to float in a body of water so that the hydrodynamically resistive portion extends beneath a surface region of wave activity and the float portion moves vertically under the influence of wave motion with respect to the hydrodynamically resistive portion, an improvement comprising mooring apparatus, the mooring apparatus comprising:

  • anchoring means at a bottom of the body of water;

    an anchor line extending from the anchoring means to a tether-buoy floating on the surface of the body of water;

    a tether line having two ends, the first end of the tether line attached to the tether-buoy, the second end of the tether line attached to the pump adjacent a vertical axis thereof and distal from a periphery of the float.
