ABSTRACT:
A simplified, self-setting marker buoy having an outer shell of abrasion-resistant plastic material, two end portions (14) that are filled with foam or hollow to provide buoyancy, an integrally formed medial portion (18) on which the anchor line (22) is wound, an anchor line (22), and an anchor weight (38). The medial portion (18) is slightly offset from the axis of rotation of the floatation unit (10) to provide rotational resistance to impede rotation of the floatation unit (10) and the resulting release of excess anchor line (22) due to the action of wind, waves, or currents. The amount of offset of the medial portion (18) is preselected to provide the maximum amount of rotational impedance that will still allow rotation of the floatation unit (10) while the anchor weight (38) descends to the bottom of the water body. The medial portion (18) also has a relatively large cross-sectional area resulting in greater ease in rewinding the anchor line (22) onto the medial portion (18). One or both of the end portions (14) can be hollow and composed of light-transmissive material with a removable cap (30) to allow access to install one or more removable lighting devices (34).
