ABSTRACT:
A mooring buoy includes a buoyant shell that defines a chamber and has a channel extending from the chamber through the outer surface of the shell. The channel accommodates a pendant line therethrough. Within the chamber is a rotating takeup/payout that rotates about a drive axle and a drive mechanism coupled to the takeup/payout device that can drive the rotating takeup/payout device to rotate in a first direction to take up pendant line slack. The drive mechanism permits the takeup/payout device to rotate opposite the first direction in order to pay out pendant line under tension. Suitable takeup/payout devices include pulleys and spools. Suitable drive mechanisms include gravity-driven mechanisms, spring-driven mechanisms, and pendulum-driven mechanisms.
