A buoy anchoring system includes an anchor device in the form of a weighted cannister that pays out line from the center of a fixed, hollow-cored bale during free fall. The line is secured against further pay out after the device impacts the bottom by wrapping about a shaft that is driven upwardly within the bale by the impact. The shaft has a line engaging cross-bar at its upper end, and is held in an extended position prior to impact by a shear pin. Author
