A retrofit kit retrofits a buoy to provide dynamic control of a freeboard of the retrofitted buoy. The retrofit kit includes buoyancy chambers, an air reservoir, and a valve arrangement. A method for retrofitting a buoy retrofits a buoy to provide dynamic control of a freeboard of the retrofitted buoy. The buoyancy chambers surrounding a vertical axis of the buoy with a center of mass of the buoy disposed on the vertical axis below the buoyancy chambers. The buoyancy chambers provide a variable buoyancy ranging from a minimum buoyancy to a maximum buoyancy. The air reservoir inflates of the buoyancy chambers. The valve arrangement dynamically sets the freeboard of the buoy upon inflation and deflation of the buoyancy chambers for varying the variable buoyancy between the minimum buoyancy and the maximum buoyancy.
