Abstract: A simple covering mechanism for use as an awning, tent, boat cover, or the like, and a method of utilization thereof. The covering mechanism includes a self-coiling continuous sheet of substantially liquid impermeable material having an upward bow when uncoiled. The sheet is mounted at a first end thereof and is releasably mounted at a second end thereof when the sheet is in an uncoiled position so that the sheet extends generally horizontally with an upward bow when uncoiled. The sheet may be constructed of a single piece of plastic heat set in its coiled position, or may include a cloth covering for ribs that provide the self-coiling function.
