A floating dock mooring article, which slidably fits around a watercraft dock pipe, comprising a flotation device attached to a mooring member and a flange generally located at the upper end thereof. A watercraft is moored to the dock, as by a rope, via the flotation mooring article. When the water level rises as due to a flood, the float will cause the mooring article to raise-up the dock pipe and maintain securement of the watercraft to the dock.
