Abstract: A prolate spheroid shaped buoy is resiliently moored to an anchor by means of a cable wound on a reel in the anchor with the reel latched to power springs coaxially wound upon a shaft extending through the reel. The springs are pretensed on the shaft, prior to deployment, and the shaft is latched against rotation by a pair of spring biased pins engaging a plunger. The reel may thus rotate freely under control of a brake as the anchor falls from the buoy during deployment. The plunger is operated automatically when the anchor falls to the ocean bottom to release the pins in sequence with one pin engaging the cable reel before the other pin releases the shaft to ensure that the springs are latched to the buoy and cable to resiliently moor the same. A plate on the plunger arm closes the bottom wall of the anchor to prevent the ingress of contaminants.
