A buoy assembly for at least partially containing a floating material on a surface of a body of water in a selected area thereon. The buoy assembly includes a roll subassembly with a core element defined by a central axis thereof and a concentric roll of a predetermined length of a barrier material wrapped around the core element, the barrier material extending between a fixed end attached to the core element and a free end thereof, and a body defining a cavity therein, the body including a mounting subassembly for locating the roll subassembly in a predetermined position therein. The body includes an aperture through which a deployed length of the barrier material passes as the deployed length exits the body, the aperture being formed for twisting the deployed length into an at least partially helical configuration.
