My invention comprises an ovoid plastic buoy of the

the body and being co-terminous at their upper ends, or
in other words, at the pole 2 of major amplitude. The
ribs extend in fact substantially for the length of the

accompanying ?gures, in which:
FIGURE 1 is an elevation partly in section, of my
ovoid buoy.
FIGURE 2 is a section on the line 2——2 of FIGURE 1. 45
FIGURE 3 is a section on the line 3—3 of FIGURE 1.
In the drawings like characters of reference designate
corresponding parts in the several ?gures.
Describing ?rst the buoy of FIGURES 1 through 3,
the same will be seen to consist of a body collectively 50

in use surmounts the pole of minor amplitude 3.
The anchoring means associated with the buoy of FIG

having a gap 5 therebetween. Above the said gap is 55
positioned an open-ended sleeve 6. From a contempla

the axes of gap 5 and sleeve 6 may be said to lie in
parallel. Although in the accompanying FIGURE 5,
