ABSTRACT:
A buoy (10) carries a light (16) at the upper end of a mast (14). The lower end of the mast (14) is connected to a buoyant body (12) which is weighted to present a maximum diameter zone (20) slightly below the water level when the buoy (10) is at rest in the water. The body (12) tapers inwardly both above and below the maximum diameter zone 20. A towing bar assembly (18) is provided on one side of the buoy (10). It includes an upwardly and outwardly sloping guide bar (30) connected at its upper end to a tow bar (36). An eye (50) at an end of a control line (46) is slidably received on the guide bar (30). An initial tug on the control line (46) causes the eye (50) to slide upwardly along the guide bar (30) until it engages a bight (38) of the tow bar (36). The bight (38) is positioned radially outwardly from the maximum diameter zone (20). Then, when the control line (46) is pulled upon, it pulls the buoy (10) into the water. Initial water movement acting on the lower portion of the buoy (10) raises the buoy (10) from the water. Then the buoy (10) moves in the water sideways while remaining substantially upright.
