Described herein is an apparatus for coupling a flotation device to a boat. The apparatus includes a clamping device with a clamp base, a fixed clamp portion extending from the clamp base, and an extensible clamp portion extendably coupled to the clamp base. Extension of the extensible clamp portion changes a distance between the extensible clamp portion and the fixed clamp portion so as to permit clamping of a portion of the boat there between. A tether member extends downwardly from the base. A retention device is associated with the tether member and operates to couple the flotation device to the boat.
