Abstract
A collapsible spar buoy made of separable sections having a flag and requiring no conventional, additional float device. A central section and a base member entrap air to serve as a float. This central section houses all the other components when the buoy and flag are stored. The flag may be conventionally mounted or centrally mounted so that its mass is centered with respect to the mass of the buoy; thus the buoy and flag assume a vertical attitude in the water.
