ABSTRACT:
An improved marker buoy having a body made of nesting segments wherein each segment has a cup-shaped lower portion filled with buoyant material and a hollow cylindrical upper portion with a cup-shaped cavity for nesting with the lower portion of a similar segment. The segments nest one within the other such that the outer wall of each cup-shaped portion reinforces the walls of the segment below it and the nesting segments are held together by a shaft passed longitudinally through the nesting segments with barbs protruding from the shaft for preventing the segments from slipping off the shaft. The segments nested one on top of the other define a cylindrical buoy, of horizontal striped pattern, standing erectly and visibly in the water by reason of a weighted, lower end on the shaft.
