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.
Claims8
A collapsible spar buoy comprising as separable components:
- an upper, flag post assembly;
- a central storage and floatation section;
- and a lower, submerged, elongate, weighted base member;
- said upper assembly, central section and base member being relatively dimensioned in length and diameter whereby said upper assembly and said weighted base member fit entirely within said central section when said spar buoy is collapsed to a storage configuration and sealing means on said central section whereby, with said spar buoy in extended assembly, said central section is sealed substantially air tight to thereby function as a float.
